XMLType - reorganize nodes?

I tried to migrate Berkeley DB XML to Oracle XML DB. Each container of Berkeley DB XML has become one table of relational database in Oracle XML DB with an XMLType column to contain the XML document:

CREATE TABLE MyTable 
    (
        id VARCHAR2(1024) PRIMARY KEY, 
        xml XMLTYPE NOT NULL
    ) XMLType COLUMN Xml STORE AS CLOB 
      XMLSCHEMA "http://xmlns.abc.de/xdb/schemas/RTIDB/abcfinlib.xsd" ELEMENT "abcfinlib"

In my application Java migration I ask Berkeley DB XML XML document and insert it on the fly in the appropriate Oracle XML DB table.

When I now selects the document XML of the Berkeley DB XML and the Oracle XML DB (to check if the copy has been a success and the two XML documents an equal somehow) XML documents are not equal because parts of the XML in the Oracle XML DB are placed in other locations in the XML document.
What is a behavior known to Oracle XML DB? I have to say one other thing when creating the database table?
How can I stop rearraning the XML document?

Oracle 11g 11.2

I created a problem where no problem is not at all? ;)

Looks like so much ;)

Here are practically two entries from geo (the /result of xml nodes), and each entry has multiple secondary entries of type address_component and a secondary entrance to the geometry of type.

I can get the entries in the result of this query:

SELECT xt.*
OF zip_tree_sort_xml x,.
XMLTABLE ("' / GeocodeResponse/result")
PASSAGE x.google_geodata_xml
COLUMNS
Path of 'FORMATTED_ADDRESS' VARCHAR2 (200) "formatted_address".
) xt;

The subnodes XML type address_component and type geometry of teas and those below:

SELECT xt.*
OF zip_tree_sort_xml x,.
XMLTABLE ('/ GeocodeResponse/result/address_component ')
PASSAGE x.google_geodata_xml
COLUMNS
Path of "LONG_NAME' VARCHAR2 (200)"long_name. "
'SHORT_NAME' VARCHAR2 (500) PATH 'short_name ',.
Path ACCESS VARCHAR2 (200) from 'TYPE_1' 'type [1]. "
Path ACCESS VARCHAR2 (200) to 'TYPE_2' 'type [2].
) xt;

SELECT xt.*
OF zip_tree_sort_xml x,.
XMLTABLE ("/ GeocodeResponse/result/geometry/location")
PASSAGE x.google_geodata_xml
COLUMNS
"latitude" NUMBER PATH 'lat ',.
"longitude" NUMBER PATH 'LNG '.
) xt;

But y at - it anyway to join the two subnodes XML below with the parent that above? So I can only get correct result attributes?
Best regards

But y at - it anyway to join the two subnodes XML below with the parent that above? So I can only get correct result attributes?

You can do chaining XMLTABLE another that will handle the address_component expandable nodes.

Data from the geometry node can be extracted at the same level as a result.

Add the xmltype attribute node

How can I add an attribute node to xml in an xmltype?
Say that I

declare
  t_xml xmltype;
begin
  t_xml := xmltype( '<x a="1"/>' );
end;

How can I manipulate this variable t_xml become

<x a="1" b="2"/>

Anton

Depends on the version.

Before 11.2.0.3:

SQL> with t as (  select xmltype('') as t_xml from dual )
  2  select insertchildxml(
  3           t_xml
  4         , '/x'
  5         , '@b'
  6         , '2'
  7         )
  8  from t;

INSERTCHILDXML(T_XML,'/X','@B'
--------------------------------------------------------------------------------

On 11.2.0.3, by using XQuery Update:

select /*+ no_xml_query_rewrite */
       xmlquery(
        'copy $d := .
         modify ( insert node attribute b {$val} into $d/x )
         return $d'
        passing t_xml
              , '2' as "val"
        returning content
       )
into t_xml
from dual
;

(not tested, but should be close)

The generic approach would require market the entire tree down recursively to the copy existing nodes and add the new in the right place.
Although XQuery (without involving XQUF) can do it, it's more of a task for XSLT:

Extract a specific node of XMLTYPE value

I have a piece of code that puts an answer Google geocoding in an XMLTYPe variable. I then use lines similar to the following to retrieve values such as address and location:
```
px_xml.EXTRACT('/GeocodeResponse[1]/result['||pn_result_number||']/formatted_address[1]/text()').getstringval();
```
It's a pretty lazy way of just looping through my results and picking a specific value.
Now, I need to extract just the addresses zip_code of XML component and can't do in the same way. Someone at - it ideas?
A call to the example is:
https://maps.googleapis.com/maps/API/geocode/XML?address=London+Eye & Bounds = 49.90878, - 7.69042. 60.88770,-0.83496 & key =
but you need to add your own key to operate. There are several components of the address and I just want to identify who has the type "zip_code".
Thank you!

It's a pretty lazy way of just looping through my results and picking a specific value.

And what about using a more friendly approach, XMLTABLE namely:

Extract data from complex XML of XMLType with nodes parents containing several internal nodes

Use an XPath predicate to target only the required component, for example:
```
select x.long_name
from xmltable('/GeocodeResponse/result'
       passing px_xml
       columns
         long_name   varchar2(200) path 'address_component[type="postal_code"]/long_name'
     ) x
;
```

Formatting XML in VARCHAR2

Hello

I am interested in an XML file/feed, and in it there are points and page breaks (< para >,
). When I extract the data in a field in varchar2, I want to preserve the structure of the paragraph/pause...

for example

SELECT   text_col
FROM     XMLTABLE('/'
                  PASSING (xmltype('<para>This is paragraph 1.<br/>This is p1, line 1.<br/>This is p1, line 2.</para>'))
                  COLUMNS text_col VARCHAR2(1000) PATH '/'
                 );

gives

This is paragraph 1.This is p1, line 1.This is p1, line 2.

What I'm after is:

This is paragraph 1.
This is p1, line 1.
This is p1, line 2.

Is it achievable?

Hello

11g, I would like to use this:

  5        return

 12       columns text varchar2(2000) path '.'
 13       )
 14  ;

TEXT
--------------------------------------------------------------------------------
Line1
Line2
Line3

but I'm not sure it works on your version. You can try however.

Another solution would be:

SQL> select utl_i18n.unescape_reference(replace(x.text.getstringval(), '

')) as text
  2  from xmltable('/para'
  3         passing xmltype('Line1&Line1.1

  4         columns text xmltype path 'node()'
  5       ) x
  6  ;

Funny problem with generating xml looks like table.
Hello
I have the following problem:

1.I has table:
CREATE TABLE DESCRIPTION
(
NUMBER OF DESC_ID
SK VARCHAR2 (500 BYTE),
OF VARCHAR2 (500 BYTE).
EN VARCHAR2 (500 BYTE)
)

2.I need to create an xml looks like:

< "NODE1" >
< "NODE2" >
data column < /de > < >
column < www.tourocloudbackup.com > < en > data
given < sk > column < /sk > sk
< / "NODE2" >

where "PAR1" and "PAR2" is CASE-SENSITIVE SETTING of RESPECT.

3. I create for that to be the next function:

If I add the new column to the table Description the XML should include this new column.
Problem is a RESPECT for the CASE, the table tags MUST be LOWER case, and of course without column DESC_ID, BUT the two NODE1 and NODE2 SHOULD be case-sensitive.

5. function whihch I cooked up in my opinion is not fast enough. IS THERE a SOLUTION to make this better? Help, please.

Do I need my own taste?

I have a treeview, and I'm currently implementing drag drop the widgets reorganization (identical to the Panel style). Here are some of the questions, I'm having a hard time understanding.
1. Is it necessary to set up my own taste. Each node represents an xml element that is stored in the memory of the plug-in and reorganize nodes will have to reorder items.
2. How do you get a unique alphanumeric combination for your own flavor, it's something that should be saved, and why is it different for Windows and Mac
3. During the reorganization, changes to widgets in the treeview do it manually or treeview should be reset and filled with the underlying xml structure. (However if refresh is performed, then the treeview will lose status, reset all the closed nodes?)
Thank you for any advice, assistance, or even sympathy

(1) own flavor? Yes, you have your own data type and a separate model that will not work for the other SD objectives.

XML support that you mention. As a general rule, would mean a drag of your object in the view of the structure (XML layout window sidebar) you instantiate a XMLElement there? Your palette would accept view structure from wildfire?

There are a lot of examples if you are looking for the CDataExchangeHandlerFor SDK.

(2) a good idea would be to reuse the script corresponding to your model class ScriptID.

If (probably not) you need an external Windows flavor, use RegisterExternalFlavor to save your flavor of chain.

(3) decouple your model tree. Do not strictly follow the examples, they are too simplified. Read about lazy notifications (e.g. TreeLazyNotificationData) - they are used to see updates of UI until they fit into.

Insert node xmltype

He said this support oracle xml db xquery 1.0 and xquery update 1.0.
I want to insert a node in the xmltype column.
My like this xmltype column:
< + photos >
< default pic = "yes" >
< master > 1.jpg < / master >
1_thumb.jpg < go > < / inch >
< / pic >
< pic >
< master > 2.jpg < / master >
2_thumb.jpg < go > < / inch >
< / pic >
< pic >
< master > 3.jpg < / master >
3_thumb.jpg < go > < / inch >
< / pic >
< pic >
< master > 4.jpg < / master >
4_thumb.jpg < go > < / inch >
< / pic >
< / photos >
My update sql like this: (the xmlquery is see xquery update 1.0)
Update t set t.info XML = xmlquery ('declare variable $e: = $d / / pic [last ()]; insert $e into node $d/pics ' PASSING t.info have "d" RETURNING CONTENT) where t.id =: id and t.info is not null
It went wrong: ORA-18150

Like the above, I have an xmltype in a table that has other non-xmltype columns.   I have a requirement to extract them out in a single xml document in a manner similar to the last SQL it.
the problem is that if I do it according to the foregoing, I add a redundant node artificially. the first node < x_data > is not necessary, but how can I go and add the xmltype column to the result without having to qualify it with another element around it?
know how to do the following:
< outerelement > < itemID > 1 < / itemID > < x_data dummyattr = "1" >
< item > blah < / item >
< element > more blah < / item >
< / x_data > < / outerelement >

Too bad... I had a moment mute:

Add several different nodes from one xmltype to another

Hello
Given the two following bits of XML:

I need to insert a few nodes of the second xml in a new node at the top of the first xml, as follows:
< root >
< InfosSuppl >
< b > < /b > valb
< d >
vald1 < d1 > < / d1 >

At the time I thought that I had to only add a few nodes (eg. b and f), I used:
with sample_data as (select xmltype ("< root >

ExtractValue (sd.xml_to_extract_from, ' / a/b / text () ').
"< /b > < f >" |
ExtractValue (sd.xml_to_extract_from, ' / a/f / text () ').
' / f <>|
((/ extrainfo > ')) updated_xml
of sample_data sd;
that worked, but I now need to add several other knots, I don't think that is the wisest way to continue to use. I tried Googling and forum searching but my search-fu must be low today, because I have not found similar examples that I can copy base my solution to. I'm sure that there is a funky way of doing it using xquery or something, but I admit not having a clue about where to start even with xquery!
We are on 11.2.0.3, and the xmltype columns are stored as a CLOB (sorry Marco Gralike!).
Can anyone help point me in the right direction please?

Read the column of XMLTYPE with Parent and several child nodes
Hello

I have an xmltype column which stores the data in the format below. There is possible that some of the parent node will have several child nodes. I'm not able to extract children nodes. Get the error as a value of type multiset... required singleton...
I tried the sub query, but it returns only the records from parent with children nodes.

I tried to use 2 xmltable querys and using the child node of the xmltable 1 as input to xmltable 2. But it returns only the records that has child nodes. But I wanted all the records of CrntRgstn and if no child node CrntDfcnys so that also displays.

Thank you

You're almost there, you just have to do an outer join:

Note: I have tested the above on 11.2.0.2 and it seems that there is a bug, if we add an outer join on the first XMLTable operator too.
Normally, the first outer join is not necessary, in order to also test on your version without it.

Extraction of a node in an XMLtype table - selection of the previous query
Hey all,.

I work with a server Oracle 11 g r2 and basically need to be able to analyse and select nodes from it. I spent hours scouring the net and reading the manual oracle xml db trying to find an appropriate solution to my problem, but I can't seem to identify the correct way to do it. I have some experience in programming, but none with databases oracle, sql or xml in general so forgive me if this is a trivial question.

OK, so the question:

I have a very simple XML file saved under catalog.xml and it is as follows:

<>Catalog
< cd >
< title > hide your heart < /title >
< artist > Bonnie Tyler < / artist >
< Country > UK < / country >
< company > CBS Records < / company >
< price > 9.90 < / price >
< year > 1988 < / year >
< CD >
< cd >
Empire Burlesque < title > < /title >
< artist > Bob Dylan < / artist >
< country > USA < / country >
< company > Columbia < / company >
< price > 10.90 < / price >
< year > 1985 < / year >
< CD >
< / catalogue >

Now, I want to be able to extract the title of the given cd a certain artist. So, for example, if the artist is "bob dylan", the title should be "empire burlesque".

Now I created an XMLType table in Oracle as follows:

CREATE BINARY XMLTYPE STORE AS XML BINARY XMLType TABLE.

I then load my xml file into oracle by:

Insert the BINARY values (XMLTYPE (BFILENAME ('XML_DIR', 'catalog.xml'), nls_charset_id ('AL32UTF8')));

So far so good.

Now for the part of the excerpt:

First of all I've tried:

SELECT extract (b.object_value, ' / catalogue/cd/title ')
Binary b
WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;

EXTRACT(B.OBJECT_VALUE,'/CATALOG/CD/TITLE')
--------------------------------------------------------------------------------

< title > hide your heart < /title >
Burlesque Empire < title > < /title >

1 selected line.

It did not work because the xml file was all in 1 row then I realized that I had to split my xml in separate rows. Doing that, I had to convert the nodes < title > a virtual table using the functions XMLSequence() and table(). These functions convert nodes two title returned by the extract() function in a virtual table composed of two XMLType objects, each of which contains a single title element.

Second test:

SELECT value (d)
Binary B,
Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
WHERE existsNode (b.object_value,'/catalog/cd [artist = "Bob Dylan"]') = 1;

VALUE (D)
--------------------------------------------------------------------------------

< cd >
< title > hide your heart < /title >
< artist > Bonnie Tyler < / artist >
< Country > UK < / country >
< company > CBS Records < / company >
< price > 9.90 < / price >
< year > 1988 < / year >
< CD >

< cd >
Empire Burlesque < title > < /title >
< artist > Bob Dylan < / artist >
< country > USA < / country >
< company > Columbia < / company >
< price > 10.90 < / price >
< year > 1985 < / year >
< CD >

2 selected lines.

It's better because it is now divided into 2 different lines so I should be able to make a selection - where, and then select the title from the artist.

However, this is where I have questions, I tried to literally hours but I can't understand how to use the results of the query above in my next. So I tried to use a suquery in this way:

Select extract (sub1, ' cd/title')
Of
(
SELECT value (d)
Binary B,
Table (xmlsequence(extract(b.object_value,'/catalog/cd'))) d
) sub1
WHERE existsNode (sub1,'/ cd [artist = "Bob Dylan"]') = 1;

However, sql * plus displays an error:

ORA-00904: "SUB1": invalid identifier.

I've tried dozens of variations to try to use subqueries but I simly can't do things.

I heard you can do also do this using variables or pl/sql, but I don't know where to start.

Any help would be greatly appreciated I tried everything at my disposal.
This should help you get started!

XMLTYPE extract some nodes
Hello
< book >
< book >
< id > 12 / < ID >
Oracle < name > < / name >
< / book >
< book >
< id > 15 / < ID >
< name > net < / name >
< / book >
< / books >

Please how can I retrieve the node containing the oracle book without the order of the element, in 10 g and 11 g

I mean that the result should be

< book >
< id > 12 / < ID >
Oracle < name > < / name >
< / book >

Thanks in advance
How about using the EXTRACT with following XPath function? :
book/books / [name = 'oracle']

The whole sample test case:
------------------------------------------------------------
CREATE TABLE testtab)
ID NUMBER PRIMARY KEY,
XML XMLTYPE
);
INSERT INTO testtab VALUES (1, XMLTYPE ('))

12
Oracle

15
NET

'));
COMMIT;

SELECT EXTRACT (xml, '/ books/book [name = "oracle"]') FROM testtab;

Update multiply nodes on the XMLType field
Hi all.
I have this table

+ 'DOCUMENT ' +.
+(+
+ 'ID' NUMBER ENABLE NOT NULL, +.
+ 'ID_ARCHIVE' ENABLE NUMBER NOT NULL, +.
+ VARCHAR2 (20 BYTE) "USERNAME," +
+ DATE 'CREATION_DATE ', +.
+ DATE "LAST_UPDATE" +
+ VARCHAR2 (20 BYTE) "LAST_USERNAME," +
+ NUMBER OF 'VISIBLE ', +.
+ VARCHAR2 (20 BYTE) 'STATE ', +.
+ 'XML' 'SYS '. ("' XMLTYPE ',) +.

It is an example of XML value:

<? XML version = "1.0" encoding = "UTF-8"? >
< root >
< fields >
< field fieldId = "text_141536485" = "true" type iterable = specifications 'text' = name of the 'simple' = value 'tiolo"="1"required ="false"status = 'ok' searchable ="true"="true"isIterate ="false"isField / > < field fieldId ="comp_1235813718"iterable ="true"type ="composite"specification ="composite"status = 'ok' searchable ="true"="true"isIterate ="false"isField >
< fields >
< field fieldId = "texte_-1661573009" iterables = "true" type = specifications 'text' = name of the 'simple' = 'New' value = "1" required = "false" status = 'ok' searchable = "true" = "true" isIterate = "false" isField / >»»
< field fieldId = "texte_-1661573009" iterables = "true" type = specifications 'text' = name of the 'simple' = 'New' value = "2" required = "false" status = 'ok' searchable = "true" = "true" isIterate = "true" isField / >»»
< / fields >
< / field >
< field fieldId = "comp_1235813718" = "false" isIterate = "true" type iterables = 'default' specification = 'default' status = 'ok' isField = "true" >
< fields / >
< / field >
< / fields >
< / root >

I'd like to update the attribute name of all fields of Pentecost fieldId = "texte_-1661573009", that is to say, "meter".

I have try this query:

SELECT d.XML.extract('//field') in DOCUMENT d
* where d.XML.existsNode ('/ / field [@fieldId = "texte_-1661573009"]') = 1; *

It returns all fields with fieldId = "texte_-1661573009".

The update:

update the document overall. OBJECT_VALUE = d.XML.updateXML(OBJECT_VALUE,'//field/@fieldId','Counter')
* where d.XML.existsNode (OBJECT_VALUE,'/ / field [@fieldId = "texte_-1661573009"]') = 1; *

I get this error:

SQL error: ORA-00904: "OBJECT_VALUE": invalid identifier
* 00904. 00000 - "% s: invalid identifier."

Could someone help me find the error?

Thank you very much!

Hello

I have try this query:

SELECT d.XML.extract('//field') in DOCUMENT d
* where d.XML.existsNode ('/ / field [@fieldId = "texte_-1661573009"]') = 1; *

It returns all fields with fieldId = "texte_-1661573009".

In fact, it returns all the fields of a document where there is at least one field with fieldId "texte_-1661573009".
It will make a difference with updateXML, because it does not update the nodes you expect.

I get this error:

SQL error: ORA-00904: "OBJECT_VALUE": invalid identifier
00904, 00000 - '% s: invalid identifier '.

OBJECT_VALUE is only used to refer to the column of a table of Type Object, such as an XMLType table.
Here, you're dealing with an ordinary table, so use the appropriate column name, that is to say "XML".

Do you want to:
```
UPDATE document d
SET d.xml = updateXML( d.xml,
                       '//field[@fieldId="text_-1661573009"]/@name',
                       'Counter' )
WHERE d.xml.existsNode('//field[@fieldId="text_-1661573009"]') = 1
;
```
?
