extraction of xmltype table in the xml output: redundant nodes

• Adding namespace to the XML output

  Hello
  
  I have a requirement to generate an XML document for the columns in the table. I use DBMS_XMLgen.getXML inside my procedure to get the XML document.
  
  The result I get after my procedure is:
  
  <? XML version = "1.0"? >
  < EMP >
  < EMPLOYEE_NO > 000017 < / EMPLOYEE_NO >
  ASSETS of < EMPLOYEE_STATUS > < / EMPLOYEE_STATUS >
  Mini < NAME_LAST > < / NAME_LAST >
  < NAME_FIRST / >
  < / EMP >
  
  But I also need to prefix and uri of namespace in the xml output. Is it possible to add the prefix and namespace uri to the xml output.
  
  So what I need, is something like below one:
  
  <? XML version = "1.0"? >
  < xs:EMP > xmlns: out = "http://xmlns:out="http:/example.org/ver1.0/ThisISTest#">
  < xs:EMPLOYEE_NO > 000017 < / xs:EMPLOYEE_NO >
  ACTIVE < xs:EMPLOYEE_STATUS > < / xs:EMPLOYEE_STATUS >
  Mini < xs:NAME_LAST > < / xs:NAME_LAST >
  < xs:NAME_FIRST / >
  < / xs:EMP >
  
  
  Any solutions or examples of code on it would be a great help.
  
  Thanks in advance.

  Strange...

  OK, back to the basics:

  What is your version of db (all four digits please)?

  The following gives the expected result?

  select xmltype('
  
  000017
  ACTIVE
  Mini
  
  ').transform(
   xmltype(
  '
  
  
  
  
  
  
  '
   )
  ).getClobVal()
  from dual;
  

• 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 you

  You 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.

• Using the overall table for the XML results

  I'm new in the flash script and it drives me crazy...

  I searched the internet and I could not find a solution for this.

  I am trying to load XML, analyze the values in the global table and use this picture later in my code... it does not work.

  _Global.AutoID = Array ();

  function ParsingXML() { }

  var pokXML:XML = new XML();

  pokXML.ignoreWhite = true;

  pokXML.onLoad = function (loaded) { }

  If (loaded) { }

  var full_niz:Array = pokXML.firstChild.childNodes;

  len:Number=full_niz.length-1//getting the number of child nodes var

  for (var i: Number = 0; i < = len; i ++) //looping hollow values

           {

  _global.AutoID [i] = full_niz [i] Sublst.ChildNodes(1).ChildNodes(0) [0] .firstChild;

            }

  trace (_global.autoid);  Back table OK

  out of //function return _global.autoid;

       }

  } //end function (loaded)

  pokXML.load ("my.xml");

  AYUSH

  What I meant is that if you load the XML e4x, you have to analyze in a table to use it. You can retrieve the syntax of e4x XMLList and use it directly in your code. You can treat the XMLList almost as you treat any array using a for each loop for example.

  Take the code below as an example and adapt it to your needs:

  var mainMenu:XMLList = this.testXML.menu;

  for each {var menu: XML (in mainMenu)}

  trace ("Menu:" + menu.@txt);

  You can use your logic to create menu main point here

  var mynavItem:Navitem = new Navitem (0, spatie * i, GlobalVarContainer.my_array [i] [0], [i, 0], false, true);

  this.holder.addChild (mynavItem); ABLE TO VIEW THE MAIN MENU

  var items: XMLList = menu.children ();

  If (items.length () > 0) {}

  for each {var point: XML (in the points)}

  trace ("point:" + item.@txt);

  Logic of creation of subitem here

  var mySubnavItem:Navitem = new Navitem (dash, spatie * (i + 1 + j), GlobalVarContainer.my_array [i] [2], [i, j], true);

  this.holder.addChild (mySubnavItem);        DISPLAYS ONLY THE LAST ENTRY IN THE SUBMENU

• Center aligning images in table using the XML file

  Hello
  I use a flash file that uses an xml file to download a series of images one by one in a photo-gate.
  There are two different widths of images. The height is always the same. Is it possible to set up so that each image that calls file xml is center aligned as part of image.
  At the present time when using the xml file to load the image she always left aligns the image when he brings it in image even if you change the alignment to center align in the Panel align.
  Does anyone have a suggestion why this happens or how to fix it?
  Thanks for the help

  I did this quickly and did not test - but if it does not directly at the exit it might give you a starting point - or someone else can correct if there are errors. I'll check tomorrow - where I am its time to go to sleep...
  CHANGE the DETAILS: Just changed a few pieces of code I posted last night - I forgot to change the statement holder_mc.loadMovie in xml.onLoad Manager. I have not tested, but its along the lines of the approach I would use to solve your problem with resizing the image. Let me know how you go with it.

• The results in the debugger do not correspond with the result in the xml output is spent OPA

  
  Hello

  I use the OPM Version 10.4.6. I am facing a problem where I have a result field which is calculated by OPM in session of the debugger gives the correct result. While the same field has a different value in the output xml file passed from OPA to another system. Please give some advice on above question.

  Kind regards

  Mounia

  Sorry, I did not respond earlier. Do you have a support call opened in this regard, otherwise there is someone who has a very similar problem.

  I answered internally on this and the problem seems to be that of mathematical accuracy and very low values, which are then compared with zero. The debugger uses a .net implementation that can give slightly different numerical values at the extremes. I think that your rules would benefit from a degree of rounding applied before you test for equality with anything. Note the type of value that I've seen is 4-16

  I have provided more information to Schneider, who also provided a (Simplified) modules and some sample data.

  The debugger uses essentially the same engine of determinations and in general, you will see exactly the same result except that you've discovered to some extremely small numbers. In your case even if the value is 4-16 in the debugger and 0 in the API (or vice versa) the effect that has on the logic is that a single value is zero, so that the other does not which translates an extra 1000 added and results of 1000 and 2000 respectively.

  by the way: it is generally a good idea to store date values in date columns.

  One of the many reasons why store date information in VARCHAR2 columns (especially VARCHAR2 (200)) is a bad idea, it's that the data invalid get there, causing errors. Avoid the conversion of columns like that at times, if possible:

  SELECT     *
  FROM     production
  WHERE     productiondate     >= TO_CHAR ( TRUNC (SYSDATE, 'IW')

  Hello

  Here are a few options...

  (1) using a scalar subquery rather than the CURSOR constructor (as long as it's supposed to always return a single line):

  SELECT dbms_xmlgen.getxml(
  'SELECT wo.work_order_no,
          ( SELECT XMLForest( regacc.work_order_no,
                              regacc.work_order_task_no,
                              regacc.regulatory_account_no )
            FROM sa_work_orde_reg regacc
            WHERE regacc.work_order_no = wo.work_order_no ) reg_test
  FROM sa_work_order wo'
  ) xml
  FROM dual;
  

  (2) incorporating a XSL transformation (Yes, still!) to copy all nodes except REG_TEST_ROW:

• Analyze the XML order getElementsByTagName node

  Is the order of the elements in a NodeList returned by a rootElement.getElementsByTagName ("item") coherent? I have an XML that returns items in order descending by date (most recent at the top).  Can I count on item (0) is always the most recent and the order preserved?

  As long as your XML file shows how you said, the order does not change.

  Item (0) should be your most recent.

• Processing the XML file

  I have a requirement to process a stream of xml files and load its content in the oracle as a name-value pair tables. Basically, my table has three columns ID, Detail_NM, Detail_val.  I have to extract the ID and the corresponding details and store it in this table. The XML file looks like in below.  I can use an extract sql but you are looking for the most effective way to do it. I would like to highlight the elements dynamically as an element may or may not be present in every game. for example. Second series below has address2 that isn't there in the first document set. Even if nothing new is introduced, I should be able to treat them without explicitly mentioning the name of the element.  Is there a better way to deal with?  Please, share your ideas.  Thanks in advance

  Thanks again.  Yes, we can have a node root here.

  -What is the average size of a single XML entity? (Number of nodes, size in bytes)? -A file can be up to 2MB size. Each ID can have different elements from 0 to 200 under him. (Each document tag).

  Sorry, missed your last answer once again.

  If there is a root node, it is even simpler.

  And you can certainly use an intermediate binary table of XMLType:

• IBY_FD_PAYMENT_FORMAT_TEXT xml output

  Hello

  IBY_FD_PAYMENT_FORMAT_TEXT used to always save the XML output, generally as follows:

  ....

  No extract has been created beforehand. Create extract. Timestamp: Wed Mar 05 12:42:20 WST 2014

  Size of the product extract - doc::590376

  After create extract, extract is not null.

  Check-in first 1 MB of generated excerpt below:

  ==================

  <? XML version = "1.0" encoding = "UTF-8"? > < OutboundPaymentInstruction...

  After application of a number of CPP (17167654 & 17176017), the XML is no longer registered in the log file.  The log looks like:

  ...

  No extract has been created beforehand. Create extract. Timestamp: Kills Mar 04 15:59:21 WST 2014

  Size of the product extract - doc::23158

  After create extract, extract is not null.

  Start formatting. Timestamp: Kills Mar 04 15:59:25 WST 2014

  Before formatting: Timestamp: kills Mar 04 15:59:25 WST 2014

  Model type: ETEXT

  ...

  Anyone would offer any suggestion as to how restore us this connected XML functionality?

  Thank you

  Hello

  This change was due to a fix implemented in bug 11828195. They have limited xml extracts to be included in the payment format logs instructions when FND 'Statement' debug level is ONE, then the section of code that primts the xml extracted for the log file is included when the FDFormatProgramUtils.java file is version 120.35.12010000.34 or 12.0.x, version 120.30.12000000.39 and more.

  You can still see, but you will need to turn on statement-level debugging.

• Validate the XML column when inserting

  Hello

  I'm on 11 GR 2.

  I have a table

  create table root_table (id number, text xmltype);

  I tried to sign up:

  Start

  dbms_xmlschema.registerSchema ('test', xmltype)

  "' < xs: schema xmlns: XS ="http://www.w3.org/2001/XMLSchema"xmlns:xdb ="http://xmlns.oracle.com"elementFormDefault ="unqualified">

  < name XS: complexType 'RootType' = >

  < xs: SEQUENCE >

  < xs: element name = "Required" / >

  < xs: element name = "Énumération" >

  < xs:simpleType >

  < xs:restriction base = "XS: String" >

  < xs:enumeration value = 'A' / >

  < xs:enumeration value = 'B' / >

  < xs:enumeration value = 'C' / >

  < / xs:restriction >

  < / xs:simpleType >

  < / xs: element >

  < xs: element name = "MinLength" >

  < xs:simpleType >

  < xs:restriction base = "XS: String" >

  < xs:minLength value = "4" / >

  < xs:maxLength value = "20" / >

  < / xs:restriction >

  < / xs:simpleType >

  < / xs: element >

  < xs: element name = "MaxLength" >

  < xs:simpleType >

  < xs:restriction base = "XS: String" >

  < xs:minLength value = "1" / >

  < xs:maxLength value = "4" / >

  < / xs:restriction >

  < / xs:simpleType >

  < / xs: element >

  < xs: element name = "MaxOccurs" type = "xs: String" maxOccurs = "2" / >

  < xs: element name = "MinOccurs" minOccurs = '2' maxOccurs = "2" / >

  < xs: element name = "Optional" type = "xs: String" minOccurs = "0" / >

  < / xs: SEQUENCE >

  < / xs: complexType >

  < xs: element name = "root" type = "RootType" xdb:defaultTable = "ROOT_TABLE" / >

  ((< / xs: Schema > '));

  end;

  /

  table should point to the table where the XML column is default, I guess that

  is the 'root' in the same line a reference to the name of the xmltype column?

  Now - how do I ensure the XML I have insert in the column "change" is validated against the schema above?

  concerning

  Mette

  
  

  For both options, save the diagram with these options (you can substitute the url of course):

  Start

  () dbms_xmlschema.registerSchema

  schemaURL-online "test.xsd.

  schemaDoc-online xmltype (bfilename ('TEST_DIR', 'test.xsd'), 873)

  local-online true

  genTypes-online fake

  genTables-online fake

  enableHierarchy-online dbms_xmlschema. ENABLE_HIERARCHY_NONE

  options-online dbms_xmlschema. REGISTER_BINARYXML

  );

  end;

  /

  Then the #1 option:

  create table root_table)

  Identification number

  text xmltype

  )

  XMLType column can store as xml binary securefile

  XmlSchema 'test.xsd' element 'root '.

  Both options will perform a validation of strict type.

  There are other possible configurations, such as CLOB based on a storage schema, but this approach is now obsolete.

  If you are only interested in whether the XML instance is valid or not, you can also use a constraint check with the XMLisValid function.

• Retrieve / search a specific node of the XML file

  Hello
  
  I have a question about reading the XML (search) in PL SQL file:
  
  There is an XML file with the following structure:
  

  <root>
    <Hnode1 attr1="value1" />
    <Hnode2 attr1="value1" /> 
       <node1_of_Hnode2 id="10" personname="Steven"/>
       <node2_of_Hnode2 id="20" personname="Christian"/>
       <node3_of_Hnode2 id="30" personname="Arnold"/>
       .
       .
    <Hnode2/>
  <root/>

  How it is possible to filter a node by one of its attribute value. For example:
  The id of a person - I guess that id = 20. In this case I would like to get the whole node (in this case node2_of_Hnode2) to get the personname = > 'Christian '.
  Just like a SELECT statement (WHERE ID = 20)
  
  Is it possible to get it in a single order or should it be buckled on all the lines in the Document. Can you please provide an example for me.
  
  Thank you for advice!

  The basic version is 10.

  Sorry, this is not a version.
  For example:

  SQL> select * from v$version;
  
  BANNER
  ----------------------------------------------------------------
  Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
  PL/SQL Release 10.2.0.5.0 - Production
  CORE     10.2.0.5.0     Production
  TNS for 64-bit Windows: Version 10.2.0.5.0 - Production
  NLSRTL Version 10.2.0.5.0 - Production
   
  

  The use of the extraction of the values?
  1. better in a Select statement. assignment directli in a variable, or by using the xmlquery function?

  PL/SQL or SQL calls to the XMLType methods such as getStringVal() or extract() function should be equivalent (save the change of context).
  However, none of them are the right way to retrieve a scalar value of a given node.
  You must use the rather extractValue() function (SQL only) for immediate release< 11.2="" and="" xmlcast/xmlquery="" starting="" with="">

  Another Question:

  I've seen a lot of options for dealing with XML files.

  In my case only query data in XML files is relevant.

  I've seen to many API called XMLDOM, DMBS_XMLDOM, XMLTYPE...

  When to use these APIs. Can you give me feedback on this please?

  It is a broad topic.
  An appropriate response will depend on your condition.

  -You have to deal with large files and if so what size?
  -Performance/memory management is a concern for you?
  -You want to extract unique values or process the XML content in the form of relational data?

  If you have any specific test cases to show us, please post in the {forum: id = 34} forum and make sure to include all the necessary details (see the FAQ).
