Delete an end (leaf) Node in an XML Document
I have an object type node, where each of them was a node of object type, which can contain a node of type object etc. I need to remove the last item and returns the new xml document, see example, any ideas?< id menuItem = "itemID" Graphic = "" name = "test01" text = "test01" > "
< id menuItem = "itemID" Graphic = "" name = "test01" text = "test01" > "
< id menuItem = "itemID" Graphic = "" name = "test01" text = "test01" > "
< id menuItem = "itemID" Graphic = "" name = "test01" text = "test01" > "
< / menuItem >
< / menuItem >
< / menuItem >
< / menuItem >
Thank you

How to remove a node in an XML document
Hello
My flex plugin loads an XML document that is passed from the ExternalInterace. I have a list control that displays the data from the XML document.
The XML looks like:
< document >
< response >
< objectlist >
< list type = "type" >
< object type = "type" name = "Value name" id = "GUID value1" >
< params >
.........
.........
< params >
< / object >
<! - several items in this list - >
< / list >
< / objectlist >
< / answer >
< / document >
I set the dataProvider of the list to xmlDoc.response.objectlist.list.object
Here, I want to delete one of the object before displaying the data nodes (in other words, I don't want one of the nodes in the document XML should appear in the list).
How can I do this? I couldn't find a way to remove a node in the XML api.
-GerardYou can either use the operator 'delete ':
delete xmlDoc.response.objectlist.list.object [5]
When the object to delete can be the fifth down (you need to play with your xml code in debugging down actual values) or convert xmlListCollection. The xmlListCollection provides easy methods to remove the offending nodes or you can provide a function filterFunction for the collection that allows you to "hide" the node. -
XML document lack of implementation in the form after adding the node
Hi all
I'm adding a new node to my XML document using java.
After I add, when I print the doc, I can see the xml code is not properly 'indexed' or 'formatted' (with a step internal node within the parent node.)
I have put OutputKeys.INDEX that Yes. But I still have this problem.
Kindlly help me regarding this.
Thank you
Sabarisri. NAfter I add, when I print the doc, I can see that xml is not properly "indexed" (sic, "indented") or 'formatted' (with a step internal node within the parent node.)
It is indeed a common place of what to get. Rarely these whitespace contravene semantic aspects of xml, but it's annoying to the human eye. The OutputKeys.INDENT on the transformer fixing certainly wouldn't heal and makes it worse.
If the lack of alignment gets enough wide, sometimes I use a custom xsl file to put an order of it. This is how the xsl looks like: it is just a slight development of an identity transformation. And I assume you are using jdk1.5 + packaged xerces and xalan.
Suppose to be called indenter.xsl, and put themselves in the working directory. Printing to a file may seem just that.
TransformerFactory tf = TransformerFactory.newInstance(); Transformer t = tf.newTransformer(new StreamSource("indenter.xsl")); //suppose the doc is the document parsed and edited in the memory, and outfile is the path to output file t.transform(new DOMSource(doc), new StreamResult(new FileOutputStream(outfile)));I use xalan namespace to control the amount of space to indent. If you don't use of xalan, just leave these namespace declaration and the xalan:indent - amounted to and let the xsl processor using its default value.
If you prefer instead of writing your own small xsl utilities, you can maybe google (mainly in using key as pretty print or a utility called htmltidy with w3c) to clean the misaligned output. Or check the documentation on the xsl processor used, some processor could have custom method to do the same.
But cleaning may still run the risk of too interpret what can hold and is not. It is important to know what you finally want what to do and adjust according to your need.

How to extract the node where the value of the node is the max in all of the XML document?
Hello
I have a transaction that refers to an xmltype in iRecruitment, containing multiple versions of the same node as follows:
(only for the example data)
{noformat} & lt; Transaction & gt;
& lt; data & gt;
& lt; ObjectVersionNumber & gt; 1 & lt; / object_version_number & gt;
& lt; EO & gt;
& lt; Attribute1 & gt; A & lt; / Attribute1 & gt;
& lt; Attribut2 & gt; B & lt; / attribut2 & gt;
& lt; /EO & gt;
& lt; / data & gt;
& lt; data & gt;
& lt; ObjectVersionNumber & gt; 2 & lt; / object_version_number & gt;
& lt; EO & gt;
& lt; Attribute1 & gt; A & lt; / Attribute1 & gt;
& lt; Attribut2 & gt; C & lt; / attribut2 & gt;
& lt; /EO & gt;
& lt; / data & gt;
& lt; data & gt;
& lt; ObjectVersionNumber & gt; X & lt; / object_version_number & gt;
& lt; EO & gt;
& lt; Attribute1 & gt;? & lt; / Attribute1 & gt;
& lt; Attribut2 & gt;? & lt; / attribut2 & gt;
& lt; /EO & gt;
& lt; / data & gt;
& lt; / Transaction & gt; {noformat}
I can extract a value for FULL-TIME 1 or 2, is not a problem.
However, how can I go on the selection of a value of an attribute below FULL-TIME X, where X is the maximum value of FULL-TIME in any node in the XML document?
I tried to the last node corresponding to my way, but it is not always the case that the FULL-TIME max will correspond to this scenario.
Any help would be greatly appreciated!
Thank you very much, Pete

Move a node in an XML (Jdev 11.1.1)
Hi all
I'm writing a query to move a node within a XML.
For example, of:
< root >
< fields >
< field id = "1" >... < / field >
< field id = "2" >... < / field >
< field id = "3" >... < / field >
< field id = "4" >... < / field >
* < field id = "5" >... < / field > *.
< / fields >
< / root >
TO:
< root >
< fields >
< field id = "1" >... < / field >
* < field id = "5" >... < / field > *.
< field id = "2" >... < / field >
< field id = "3" >... < / field >
< field id = "4" >... < / field >
< / fields >
< / root >
I can do it in 3 steps:
1 exctractnode +//field[@id="5"]+ for recovery < field id = "5" >... < / field >
2 deleteXML for the +//field[@id="5"]+ node
3 insertXMLBefore +//field[@id="2"]+
Is it possible to do in 1 single step and for several overseas departments? (I need to do it in java)
Thank you

My event.result may or may not return a node in the xml file. How can I avoid that TypeError: Error #1009: cannot access a property or method of a null object reference.
I have a very simple question. I want to take the value of
Event.Result.Item.nodeindex1.nodeindex2.Row.MyValue;
and assign it to a text field
mytextTi.text = event.result.item.nodeindex1.nodeindex2.row.myvalue;
But if a part of the tree is missing, which is also valid, so I get TypeError: Error #1009: cannot access a property or method of a null object reference.
I tried various solutions such as the following. Is there any simple way to do this?
If (event.result.item.nodeindex1.nodeindex2.row.myvalue! = undefined)-does not work
Unfortunately, one must test all levels to ensure that it is not null before the reference to it. You can take advantage of the short-circuit evaluation in tying together, for example
if (event.result.item && event.result.item.nodeindex1 && event.result.item.nodeindex1.nodeindex2 && event.result.item.nodeindex1.nodeindex2.row && event.result.item.nodeindex1.nodeindex2.row.myvalue) { // access the variable } else { // one of the XML nodes in the path is null }Or you could stay away from her a little hacky and wrap the reference in a try/catch block.

Change "current node" of the XML object
Hello
I am trying to edit the "current node" of an XML object, but I still don't know what will be the current node.
My XML object to load an external XML file:
< mx:XML id = source="assets/article_text.xml"/ "featureData" >
and I read that data through a < mx:Repeater > create a < mx:TextArea > for each 'currentItem '.
< mx:Repeater id = dataProvider = "{featureData.body_text.children ('repeatParas')}" >
"< mx:TextArea htmlText =" {repeatParas.currentItem} "width ="80% "borderStyle ="none"click =" showBodyEditor (event, event.currentTarget.getRepeaterItem ()) "verticalScrollPolicy =" off "creationComplete ="resizeTextArea (event); "updateComplete ="resizeTextArea (event); "/ > < / mx:Repeater >
A click on < mx:TextArea > event load a pop-up window containing a RichTextEditor that contains the content of currentItem:
private void showBodyEditor(event:Event,_item:String):void {}
var pop1:BodyEditor = BodyEditor (PopUpManager.createPopUp (this, BodyEditor, true));
Set the properties of the custom component BodyEditor.
POP1.showCloseButton = true;
POP1.targetBodyText = event.currentTarget;
POP1. CurrentNode = item;
PopUpManager.centerPopUp (pop1);
}
I then passes the value of everything that has been entered in the return to the initial < mx:TextArea > RichTextEdior via a function on a button click event '' made '' (processBodyText()):
[Bindable]
public var targetBodyText:Object;
[Bindable]
public var currentNode:String;
Transfer data to text boxes
private function processBodyText (): void {}
targetBodyText.htmlText = String (bodyTextForm.htmlText);
currentNode = String (bodyTextForm.htmlText);
Remove pop-up.
PopUpManager.removePopUp (this);
}
But what I can't do is actually updated for that node in the featureData XML object without explicitly saying what node to update (for example, it works: parentApplication.featureData.body_text.p [1] = String (bodyTextForm.htmlText);) I don't necessarily know which node to update, I just want to be able to update some node I happen to be editing at the time.
Is this possible?
Thanks to anyone who can enlighten us!I'll reply to my own post (where everyone was watching).
I just changed the parameters/variables currentNode type Object (instead of string) and within the processBodyText function, I replaced
currentNode = String (bodyTextForm.htmlText);
with
currentNode.setChildren (bodyTextForm.htmlText);
who updates the node in the XML data provider.
I still need to get rid of some of the gobblygook of html that is passed to the rear (for example < TEXTFORMAT LEADING '2' = >) but as long as I am able to update the current node, I'm happy (for now).

restrict the application of hierarchy based on a given value at the leaf node level
Is it possible to restrict a query of the hierarchy based on a test given at the leaf node level?
For example, in the data presented below, I like to shoot the entire hierarchy for terminal nodes that have 'John' in the criteria:
Parent value criteria
Z
A Z
B HAS
C B John
D B Smith
E Z
F E
John F G
H F Neal
I have F John
Filertering on John I want to return together to resemble the following prints:
A
B
C
F
G
I have
I tried the following, but it only gives me the nodes:
SELECT
LPAD (' ', (LEVEL) * 3,'.) ') || t.Valeur
OF tbl_test t
WHERE t.criteria = "John".
START WITH t.valeur = "Z".
CONNECT BY PRIOR t.valeur = t.parent;
Rule return form the above query:
C
G
I have
Any help is greatly appreciated.It is possible, but not conventional =)
Sys_connect_by_path allows you to concatenate the path and another request of the hierarchy of dividing a value generated in the rows.
with t as ( select 'Z' as Val , null as Par, null as Criteria from dual union all select 'A' as Val , 'Z' as Par, null as Criteria from dual union all select 'B' as Val , 'A' as Par, null as Criteria from dual union all select 'C' as Val , 'B' as Par, 'John' as Criteria from dual union all select 'D' as Val , 'B' as Par, 'Smith' as Criteria from dual union all select 'E' as Val , 'Z' as Par, null as Criteria from dual union all select 'F' as Val , 'E' as Par, null as Criteria from dual union all select 'G' as Val , 'F' as Par, 'John' as Criteria from dual union all select 'H' as Val , 'F' as Par, 'Neal' as Criteria from dual union all select 'I' as Val , 'F' as Par, 'John' as Criteria from dual ) select distinct regexp_substr(path, '[^,]+', 1, level) as val from ( SELECT sys_connect_by_path(val,',') as path , rownum as row_id FROM t WHERE t.criteria = 'John' START WITH t.val = 'Z' CONNECT BY t.par = PRIOR t.val ) connect by nocycle regexp_substr(path, '[^,]+', 1, level) is not null and prior row_id= row_id and prior dbms_random.value is not null -
I was ruining my brain on this and I am sure that it is possible that I am not sure what is the appropriate search expression.
If I have an XML document, like this:
elements <>
< item >
foo < linkurl > < / linkurl >
< item >
< linkurl > bar < / linkurl >
< / point >
< / point >
< / object >
Lets say, I am looking for the parent of the item element that has an element linkurl with value 'bar' I expect to write something like this:
< cfset itemArray = xmlSearch (xmlDoc, "ancestor: / / item [linkurl = 'bar']") >
I know that for this case specific I could access it directly, but in my case, it can be a lot < element > tags nested so I want it to be dynamic, so that I can continue to walk up the tree.
Any help will be appreciatedThis has been posted a few times because of a bad internet connection, in any case with my XPath Explorer plugin faithful, I was able to get the solution:

ORA-19030: invalid method for the schema not based XML Documents
Hi everyone can u help me please when I am trying to execute query below his throw errror
DECLARE
doc xmltype.

The error I get is following
ORA-19030: invalid method for the schema not based XML Documents
Yes, Odie meant something like that.
See how the employee node can now occur more than once in the employees node.

Schema validation fails on the transformed XML document
OK, this is weird.
I get XML files that are supposed to conform to a given XSD. There are dozens of different parties who send these files. To be more precise, I refer to the Ontario Energy Board (OEB) PIPE Documents.
I found that at least one sender sends invalid files. I can't that fixes to the source, so I'm working around that.
for example
Oracle is not like this:<?xml version="1.0" encoding="UTF-8"?> <PIPEDocument xmlns="http://www.oeb.gov.on.ca" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.oeb.gov.on.ca/ PIPEDocument.xsd" Version="4.0" DocumentReferenceNumber="xxx" CreationDate="20110825100008000ES"> <MarketParticipantDirectory> <Sender> ...
OK, so to work around this problem, before schema validation, I apply an XSLT transformation to clean the top-level element:ORA-31154: invalid XML document ORA-19202: Error occurred in XML processing LSX-00344: namespace values "http://www.oeb.gov.on.ca" and "http://www.oeb.gov.on.ca/" differ
Nice: the fact that it is intended for:<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.oeb.gov.on.ca"> <xsl:output method="xml" indent="no"/> <xsl:template match="/"> <xsl:copy> <xsl:apply-templates/> </xsl:copy> </xsl:template> <xsl:template match="*"> <xsl:if test="local-name() = name()"> <xsl:element name="{local-name()}"> <xsl:apply-templates select="@*|node()"/> </xsl:element> </xsl:if> </xsl:template> <xsl:template match="@*"> <xsl:if test="local-name() = name()"> <xsl:attribute name="{local-name()}"> <xsl:value-of select="."/> </xsl:attribute> </xsl:if> </xsl:template> </xsl:stylesheet>
If I now the schema validate the above transformed XML, then it validates OK.<?xml version="1.0" encoding="UTF-8"?> <PIPEDocument xmlns="http://www.oeb.gov.on.ca" Version="4.0" DocumentReferenceNumber="50520110825080908VA0001.EBT" CreationDate="20110825100008000ES"> <MarketParticipantDirectory> <Sender> ...
Large? No, if I try to turn on the fly (i.e. without first transformation and followed by reading in the transformed data from the file), I get a strange error:
declare v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML()); v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; begin if v_xml.isSchemaValid(v_xsd_name) = 1 then dbms_Output.put_line('valid'); else dbms_Output.put_line('invalid'); --in order to get specific error info for a non-schema message need to convert the XML to schema based v_xml := v_xml.createSchemaBasedXML(v_xsd_name); v_xml.schemaValidate(); end if; end; /
Exsqueeze me? What element in the schema?ORA-31043: Element '' not globally defined in schema ''
The transformation itself works very well. Specifically, if I run the following:
... I get the desired result. Of course, if I save the result file and validate the fact that it works:select xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604.xml'), 0).transform(XDBURIType('/ERS_TEST01/PIPE/XSLT/V1.0/pre_validate_XSLT.xsl').getXML()).getclobval() from dual;
I would like to join example XML file, but it contains customer data so I can't do that. I would fix the XSD but it is the nest of a rat of 50 XSD with includes and a 300 script online registration scheme, so I can't do that.declare v_xml xmltype := xmltype(bfilename('ERS_FILE_LOAD_308', 'DecryptedFile-30873604_manually_saved.xml'), 0); v_xsd_name varchar2(255) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; begin if v_xml.isSchemaValid(v_xsd_name) = 1 then dbms_Output.put_line('valid'); else dbms_Output.put_line('invalid'); --in order to get specific error info for a non-schema message need to convert the XML to schema based v_xml := v_xml.createSchemaBasedXML(v_xsd_name); v_xml.schemaValidate(); end if; end; /
What I'm missing here?
Looks like an Oracle bug for me at this isSchemaValid binds to a beginning of the XML instance and not to the instance transformed.
thoughts?

That wouldn't be surprising. There are "few" bugs on the XSL transformation.
Here's a recently posted: {: identifier of the thread = 2245703}The solution was to serialize the output and analyze again.
So, what you describe on 'reading of a works file' makes me think it's the same kind of problem.You can also view the contents of the variable just after that:
v_xml := v_xml.createSchemaBasedXML(v_xsd_name);?

What is the best way to apply choice relational tables in the XML document?
I've got an XML document from outside I turn with full DB XSLT document.
Some parts of the document contain codes I want to tranfsorm to significant labels of relational tables in our database.
On road is to disassemble the XML into the relational views and join these views with tables of choice and then back, this time with labels translated, using XMLElement, etc...
Is there another way less heavy? For example,.
Select updateXML)
xml_dta
,'/ / section_to_translate/node_to_translate/variable / text () '
,(
Select the label
of table_recherche
where Group = extractValue (current_node, '... / Group/Text () ')
and code = extractValue (current_node, '... / variable/Text () ')
)
) xml_dta
from my_table
where... criteria
However, I do not know how to move from the current node to the extractValue function (if it is possible?.)
Anyone done the second way?
Thank youYou didn't tell the version of your database, so I assume one of them later.
You can include the part of the translation in the XSL transformation, by accessing an external research paper generated from the database beforehand.
Here is an example of use of the HR diagram example:
(1) the source document that are to be processed: emp.xml

Merge the XML document in a table
Hello
I want to merge some of the values of an xml document in a table "Project_Table".
CREATE TABLE Project_Table
(
TASK_ID NUMBER (15),
TASK_NAME VARCHAR2 (100 BYTE),
START_DATE DATE,
)
I am using the following procedure, that I adapted from another post. It inserts null values, I think because I'm not showing the nodes correctly.
DECLARE
BFILE v_bfile: = BFILENAME ("'DTEMP","test.xml");
v_clob CLOB.
BEGIN
-Create directory DTEMP as "C:\TEMP";
-grant read the < schema > DTEMP directory;
DBMS_LOB.CREATETEMPORARY (v_clob, TRUE);
DBMS_LOB. OPEN (v_bfile, DBMS_LOB.lob_readonly);
DBMS_LOB. LoadFromFile (v_clob, v_bfile, DBMS_LOB.lobmaxsize);
Dbms_output.put_line (v_clob);
MERGE IN project_table t
USING (SELECT TO_NUMBER (EXTRACTVALUE (VALUE (x), ' / task ')) task_id,)
To_date (EXTRACTVALUE (value (x), "/ start"), 'DD-MM-YYYY') start_date,
EXTRACTVALUE (value (x), "/ name") TaskName
(SELECT XMLTYPE (v_clob) XML
THE DOUBLE).
TABLE (XMLSEQUENCE (EXTRACT (xml, ' / project'))) x) r
WE (t.task_id = r.task_id)
WHEN MATCHED THEN
UPDATE
SET t.start_date = r.start_date, t.task_name = r.task_name
WHEN NOT MATCHED THEN
INSERT (task_id, start_date, taskname)
VALUES (r.task_id, r.start_date, r.task_name);
COMMIT;
END;

Any ideas how to change the procedure, in order to merge the data in the xml document in the table?
Thank youHello
Here's what you need in your USING clause:
SELECT to_number(extractvalue(column_value, 'task/@id')) as task_id, to_date(extractvalue(column_value, 'task/@start'), 'YYYY-MM-DD') as start_date, extractvalue(column_value, 'task/@name') as task_name FROM TABLE( XMLSEQUENCE( EXTRACT(xmltype(v_clob), '//task') ) )Since you want nodes "task" request, just extract them directly. In addition, 'id', 'start', 'name' is attributes, you must access them with an '@'.
You can also take a look at function XMLTABLE (which tends to replace construction TABLE (XMLSEQUENCE (...))):
SELECT * FROM XMLTABLE( '//task' passing xmltype(v_clob) columns task_id number(15) path '/task/@id', start_date date path '/task/@start', task_name varchar2(100) path '/task/@name' )Edit: the XMLType constructor overload taking a BFILE type as an argument, so you can simplify the code a bit more:
DECLARE v_xml XMLTYPE := XMLTYPE( BFILENAME('DTEMP', 'test.xml'), nls_charset_id('AL32UTF8') ); BEGIN MERGE INTO project_table t USING ( SELECT * FROM XMLTABLE( '//task' passing v_xml columns task_id number(15) path '/task/@id', start_date date path '/task/@start', task_name varchar2(100) path '/task/@name' ) ) r ON (t.task_id = r.task_id) WHEN MATCHED THEN ... WHEN NOT MATCHED THEN ... ; ... END;HTH
