[XMLType] : Appending list of XML elements
hi everybody,
I have a lttle question : a would like to append a list of XML elements to another XML document :
I have two XMLs :
<rowset><A>..</A> <A>..</A></rowset> (1)
and
<rowset><B>..</B> <B>..</B></rowset> (2)
and I would like to have
<rowset><A>..</A> <A>..</A><B>..</B> <B>..</B></rowset>
I have generated the two XML (1) and (2) by using DBMS_XMLGEN package, and I have them stored in an XMLType, but I dont know how to operate to get the wanted result.
Can anybody tell me how to do this in a PL/SQL program?
thanks,
Marie.
I don't use XSLT, i just query the XML-documents stored in an XMLType column with a simple SQL-statement.
I have posted a simple example over here Re: Is it possible to influence the creation of empty elements?

XML file too large or XML element too large
I am attempting to import an xml file into the repository and have it shred into the object-relational tables. I registered a schema and it created object-relational xml_tables, triggers, and types. The full xml file is > 80MB. XDB created all the fields as VARCHAR2(4000).
error code when importing the full XML file. This is what I need to ultimately fix.
DECLARE
res BOOLEAN;
BEGIN
res := DBMS_XDB.createResource('/home/pharma/drugbank.xml',
bfilename('XMLPHARMA', 'drugbank.xml'),
nls_charset_id('AL32UTF8'));
END;
COMMIT;
XML file encounters errors on the import.
An error was encountered performing the requested operation
ORA-30951: Element or attribute at Xpath references exceeds maximum length
ORA-06512 at "XDB.DBMS_XDB", line 315
ORA-06512 at line 4
30951.00000 - "Element or attribute at Xpath %x exceeds maximum length"
*Cause: An attempt was made to insert a node of length exceeding the maximum length (specified by the maxLength facet) into an XML document.
*Action: Do not attempt to add a node exceeding the maximum length to XML documents.
Vendor code 30951Error at Line:18I would guess that some of the fields have max lengths > 4000. I plan to annotate the schema with SQLType="CLOB", but need to know which fields to change. I was able to copy the xml file and reduce that xml file to one record, which imported into the tables. My plan was to write a view over the bfile to get the lengths of certain fields, annotate the .xsd with CLOBS where needed, and then import again. In order to do that, I have a 1 record file imported into a table and as a bfile.
Here is my code selecting length from a generated object-relational table of only one record.
CREATE OR REPLACE VIEW pharma.drugs_vw AS
SELECT d.*
FROM drugs, XMLTABLE
('/drugs' PASSING OBJECT_VALUE COLUMNS
drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id',
name VARCHAR2(50) PATH 'drug/name',
description VARCHAR2(4000) PATH 'drug/description'
) d
select max(length(drugbank_id)) as dbidlen,
max(length(name)) as nmlen,
max(length(description)) as desclen
from drugs_vw;
DBIDLEN NMLEN DESCLEN
7 9 229
1 row selected.Here is the code for the bfile. Same results, but using deprecated functions. I read the whitepaper, Oracle XML DB: Best practices to get optimal performance out of XML Queries. It says that extract(), extractvalue(), Table(XMLSequence()), and XMLType() are deprecated in 11gr2.
-- Note extractvalue is deprecated in 11gr2 replaced by W3C standard
-- XMLCast(XMLQuery())
-- TABLE(XMLSequence) is replaced by XMLTable
-- XMLType() is replaced by XMLParse()
SELECT max(length(extractvalue(column_value, '/drug/drugbank-id'))) dbidlen,
max(length(extractvalue(column_value, '/drug/name'))) nmlen,
max(length(extractvalue(column_value, '/drug/description'))) desclen
FROM TABLE(XMLSequence(XMLTYPE(bfilename('XMLPHARMA',
'db00001.xml'),nls_charset_id('AL32UTF8')).extract('/drugs/drug'))) d
WHERE ROWNUM <= 5;
DBIDLEN NMLEN DESCLEN
7 9 229Is this better code for getting the maximum length of xml fields from a bfile? Here is what I have so far. This works on a single drugbank-id.
SELECT max(length(drugbank_id)) AS dbidlen,
max(length(name)) AS nmlen,
max(length(description)) AS desclen
FROM (XMLTABLE('*'
PASSING (XMLType(bfilename('XMLPHARMA', 'db00001.xml'),nls_charset_id('AL32UTF8')))
COLUMNS
drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id',
name VARCHAR2(50) PATH 'drug/name',
description VARCHAR2(4000) PATH 'drug/description'
);I try to run it on the full file and get this error

*Cause: XML parser returned an error while trying to parse the document.

http://www.oracle.com/technetwork/database/features/xmldb/xmlqueryoptimize11gr2-168036.pdfI attempted to insert the xml file into an xml table and into a relational table with an xml column both based on the schema. I get the same errors.

XMLType column based on XML Schema: several questions
Hi,
I've a table on an oracle db version 10.1.0.4 where I stage the xml files containing orders created on a third party's system using BizTalk.
Although the storage I opted for is based on an XML Schema, defined by this third-party, I am facing big perfomance issues with files bigger than a few hundreds of kBs.
For instance, a 32Mb file takes more than 2 hours to be processed.
Now, after reading other threads in this forum and the documentation, my understanding of the problem is that the whole issue is with the correct indexing of the nested tables.
Here is my current XML Schema definition:
<?xml version="1.0" encoding="UTF-8"?>

When I registered the XMLSchema, the following types and tables were automatically created and you can see the hierarchy below:
(by the way, I could not find any xdb_utilities.printNestedTables mentioned elsewhere)
XML_ORDERS
|_PickData381_T
|___ProdRun382_T
|_____PickWave388_COLL
|_______PickWave383_T
|_________Customer387_COLL
|___________Customer384_T
|_____________InvOrder386_COLL
These objects are then used in the following nested tables:
TABLE_NAME TABLE_TYPE_NAME PARENT_TABLE_NAME PARENT_TABLE_COLUMN
SYS_NTaK/5zar5S0WitSsgu6OKPQ== PickWave388_COLL PickData389_TAB "XMLDATA"."ProdRun"."PickWave"

Note that I cancelled this operation before it was over so I imagine that these figures refer to the statistics as of the time when the operation was interrupted.
So, here are finally my questions.
In order to create the constraints on the nested tables as shown in other threads, do I need to drop the existing xml_orders table and ancillary object types and recreate them or is there a way to add such constraints using the existing system generated object names?
Secondly, the xml_orders table may contain severale documents, not just one and his current primary key is the column ID. So, in order to uniquely identify the deepest element in the xml document, I need first to select the relevant document by means of the id column.
Would it be better to create the indexes containing this id column together with the nested_table_id and array_index?
Thanks for you help.

PS: I wrote a 10 lines xsl transformation that I passed on to Saxon together with the 32Mb file. It took less than 1 minute to produce a flat file that was loaded almost instantly by SQL*Loader. So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

[CS3] [JS] add XML Element to Insertion Points
hi list,
i'll do some text parsing in indesign cs3 intended to add some xml elements to my document.
i just wonder why i can't markup an insertion point. is the following approach correct? The code works fine, only the return value (stored in the _xml variable) is not the new element but the parent element. The same code works without using the insertion point (marking up the text object [xmlElements.add(_dokument.xmlTags.item("index") , erg[0]))] ).
Any ideas or thoughts?
var _dokument = app.activeDocument;
main ();
// ** main ()
function main() {
//Set the find options.
app.findGrepPreferences = NothingEnum.nothing;
app.changeGrepPreferences= NothingEnum.nothing;
//find any string encloased by @
app.findGrepPreferences.findWhat = "@.*?@";
erg = _dokument.findGrep();
while (erg.length > 0) {
_xml = _dokument.xmlElements[0].xmlElements.item("text").xmlElements.add(_dokument.xmlTags.item( "index") , erg[0].insertionPoints[0]);
erg[0].contents = "";
erg = _dokument.findGrep();hi dave,
gui testing is always a good idea :-) but in this case the behaviour is different:
your observation is correct (anyway at least a strange behaviour compared to any xml editing tool i know == how adobe intended to insert an empty element?), tagging in the gui a tagged insertion point tags the whole story.
in the script a new element is added but the return value is the parent element (the xmlElement of the whole story).
this causes a problem when i add an attribute (the intention of the above script is to add references) which is added to the parent element.

Carriage Returns and Tabs in XML element
I have a number of carriage returns and tabs within an xml element. When I take that element I would like it to transform to html in which I am then displaying within a JEditorPane. However, when I do this it is one long string. I have tried the xml:space="preserve" within that element and this still is not working.
Here is part of the xml with the carriage return line feeds. The element that I am talking about is called pseudocode. You can see it is displayed correctly below.
Design Document XML : <?xml version="1.0" encoding="ISO-8859-1"?><design-doc><title-page><title>Testing Document</title><class-prepared-for>Lloyd</class-prepared-for><authors>Ben Garbers</authors><date-created>September 23, 2004</date-created></title-page><introduction text="This is the introduction.

if (player =null)
NullPlayerException;
if (NOT (isPlayerNameExist(player)))
throw PlayerNameNotExistException;
/* Ensure player name exist in the team already*/
i ? 1;
while (i <= length(mPlayers)) {
if (mPlayers.mPlayerName != playerName)
throw PlayerNameNotExistInTeamException;
this.mPlayers ? this.mPlayers - player;</pseudocode>
However, when I do the transformation I get the following with the pseudocode:
/* Ensure that player name exist in the system*/if (player =null) NullPlayerException; if (NOT (isPlayerNameExist(player))) throw PlayerNameNotExistException; /* Ensure player name exist in the team already*/ i ? 1; while (i <= length(mPlayers)) { if (mPlayers[i].mPlayerName != playerName) throw PlayerNameNotExistInTeamException;}this.mPlayers ? this.mPlayers - player;
It looks like it adds some spaces but no carriage returns or line feeds.
My transformation code is the following:
public ParseFile(String xmlString) {
try {
//Here we will load the correct style sheet for the message
//that will be formatted.
String urlString = "DesignDocument.xsl";
URL url = this.getClass().getResource(urlString);
System.out.println("URL to style sheet = " + url.toString());
String styleSheetName = url.getFile();
System.out.println("Style sheet name : " + styleSheetName);
InputStream styleSheetInputStream = this.getClass().getResourceAsStream(urlString);
//We will than load our SAXParerFactory and parse the message.

I have been searching and trying to figure this out forever. Any help would be greatly appreciated. Bottom line is that I want carriage returns and tabs to work when transferring from the xml to xsl.I get the following line when adding the <pre> tags.
/* Ensure that player name exist in the system*/if (player =null) NullPlayerException; if (NOT (isPlayerNameExist(player))) throw PlayerNameNotExistException; /* Ensure player name exist in the team already*/ i ? 1; while (i <= length(mPlayers)) { if (mPlayers[i].mPlayerName != playerName) throw PlayerNameNotExistInTeamException;}this.mPlayers ? this.mPlayers - player;
On the screen this is shown on 1 line. It looks like the tabs are working correctly. However, the carriage return, line feeds do not seem to be working. The xml that is pushed into the transformation has the carriage returns and line feeds and is formatted correctly. There has to be something happening when the xsl takes the xml String. When I add <BR></BR> within the xml that doesn't seem to work either.
I am really sumpted. If you could help DrClap I would really be appreciated. -
Remove XML tags from XML element in Oracle
Hi,
I have a requirement where I have to remove all the xml tags from xml element with banks, currently I'm using replace 4 times to replace all different types of xml tags, performance is really bad. is there any better option to remove xml tags from xml data leaving the actual data. please find the example data below.
select
TO_CLOB(REPLACE(REPLACE(REPLACE(REPLACE
('<Concatcolumn><ConcatGroupID>MyText Data goes here </ConcatGroupID><ConcatGroupID>Data agian</ConcatGroupID></Concatcolumn>','<ConcatGroupID>'),'<Concatcolumn>'),'</ConcatGroupID>',';'),';</Concatcolumn>')) AS Concatcolumn

Multi-level nested tables for repeatable XML Elements
Hi there,
Suppose we have a XML Schema „ASchema“ like this (XMLDB schema annotations are left out for simplicity):
<xs:schema xmlns:xs=" .... " />
<xs:element name=“A“>
<xs:complexType>
<xs:sequence>
<xs:element name=“B“ maxOccurs=“unbounded“/>
<xs:complexType>
<xs:sequence>
<xs:element name = “C“ maxOccurs=“unbounded“/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
After registering this schema in Oracle, I can define a table like this:
CREATE TABLE ATable
id NUMBER,
doc XMLTYPE
XMLTYPE COLUMN doc
XMLSCHEMA “ASchema“ ELEMENT “A“
VARARRAY doc.“XMLDATA“.“B“ STORE AS TABLE “BTable“
((PRIMARY KEY (NESTED_TABLE_ID, SYS_NC_ARRAY_INDEX$)) ORGANIZATION INDEX)
This creates a nested table "BTable" within the table "ATable". So far so good, I can use this nested table to gain faster access on every possible subelement of Element B when I set an appropriate index.
I now want to create another nested table for element “C“ like this:
DROP TABLE ATable;
CREATE TABLE ATable
id NUMBER,
doc XMLTYPE
XMLTYPE COLUMN doc
XMLSCHEMA “ASchema“ ELEMENT “A“
VARARRAY doc.“XMLDATA“.“B“ STORE AS TABLE “BTable“
((PRIMARY KEY (NESTED_TABLE_ID, SYS_NC_ARRAY_INDEX$)) ORGANIZATION INDEX)
VARARRAY doc.“XMLDATA“.“B“.“C“ STORE AS TABLE “CTable“
((PRIMARY KEY (NESTED_TABLE_ID, SYS_NC_ARRAY_INDEX$)) ORGANIZATION INDEX)
But this statement fails with the error message something like „ ... no such attribute ... „
And here's my question: is it possible to create nested tables for repeatable XML Elements that are subelements of other repeatable XML Elements ? And if so, how can I do it ?
Thank you very much in advance
JanFound a (partial) solution myself:
If you add the attribute xdb:storeVarrayAsTable="true" to the root element of the XML schema, Oracle XMLDB generates nested tables for all repeatable XML Elements while registering the XML schema.
Unfortunately, the names of these nested tables are system-generated, hence it's a bit uncomfortable to set indices on them. You can find out the names of these nested tables as follows:
select table_name, parent_table_name, parent_table_column from user_nested_tables;
Further information on that subject is supplied in the following thread:
Re: default tables for elements with maxoccurs > 1
It would be nice if there was a way to name the generated nested tables via appropriate XMLDB schema annotations.

XML Element of XML Element of XML Element (and so on...)
Here is my XML data (shorted, in a file myFile):
<LiveData>
<Voltage>
<Total>
<VoltageNow>1052</VoltageNow>
</Total>
</Voltage>
<Power>
<Total>
<PowerNow>345</PowerNow>
</Total>
</LiveData>
I would like to get the VoltageNow and PowerNow values, but the following script does not work:
tell application "System Events"
set elem1 to XML element 1 of XML file myFile /*<LiveData>
set power to XML elements of elem1 whose name is "Power"
set total to XML elements of power whose name is "Total"
set powernow to value of XML elements of total whose name is "PowerNow"
end tell
Error: System Events got an error: Can’t make {} into type string.
BTW, I don't want to use XML Element X because the order may change.
What is the correct method to traverse these elements to obtain values?AppleScript can handle the strings, but the System Events XML Suite doesn't work with text strings - it deals with the XML objects, which have name and value properties. The handler can be modified to show the names of an element, but it is just designed to work with the XML Suite.
The contents of an XML file is just text, so you can forgo System Events and just use regular text manipulation statements, or use another tool such as the Satimage XMLLib osax, which is much more robust and does include commands to display the XML object as a string.
By the way, my original handler was designed and tested in Leopard, but I discovered a Snow Leopard bug that alters the way it returns array/list contents. The following script has changes that return the functionality, in addition to a dialog handler that will display lists:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
font-weight: normal;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px; height: 340px;
color: #000000;
background-color: #DAFFB6;
overflow: auto;"
title="this text can be pasted into the Script Editor">

How to insert Text physically to xml in xml Element
hello friends,
I am newb of jDom. i am trying to change xml "Element's"--->"Text". My xml is as follows .....
<?xml version ="1.0">
<Elements>
<code>
<data>EE550</data>
</code>
</Elements> I am trying to replace that "<data>" by <data>AA550</data>
my code is as below
SAXBuilder sb = new SAXBuilder();
Document doc = sb.build(new File("src/xml/M90EE.xml"));
Element element = doc.getRootElement();
List children = element.getChildren();
String key = (element.getChild("text").getChild("mkey").setText("AA550").getTextTrim()); System.out.println("mkey :"+key);
output:
mkey :AA550 but is it possible to change in the xml file phisically.
thanQ
Ajayhello Reegz,
ThanQ so much for perfect solution....
when i do like that it is actually adding text to the existing Element Text.. so i wrote as follows....
SAXBuilder sb = new SAXBuilder();
Document doc = sb.build(new File("src/xml/M90EE.xml"));
*String skey = (element.getChild("text").getChild("mkey").removeContent().toString());* //--------->step 1
*String skey1 = (element.getChild("text").getChild("mkey").addContent("ISO9001").toString());* //-------->step 2
String rdmkey = (element.getChild("text").getChild("mkey").getTextTrim());
XMLOutputter serializer = new XMLOutputter();
String str = serializer.outputString(doc);
FileWriter fr = new FileWriter("src/xml/M90EE.xml");
fr.write(str);
fr.flush();
fr.close();Is there any other way to replace text in step1 and step2 other than above or will it be enough for multiuser programming. Because this application will be accessed by so many number of user's what do u sujjest.
thanQ ...

XML element to wanted position in content text?
Hi,
I am using java's XML document builder (javax.xml.parsers.*)....
is it possible to create XML element to wanted position in content text, such as:
<mycontent>
Here comes text <AndHereIsElementInWantedPosition ... /> and the normal text does continue.
Here comes text (2) <AndHereIsElementInWantedPosition ... /> and the normal text (2) does continue.
</mycontent>
I see only Element::appendChild(), and Element::setTextContent() functions, but it seems it's not possible with those functions.
and if it's possible, what functions I should use to read Elements & their position from content text? (Node class doesn't tell the position).is it possible to create XML element to wanted position in content textYes. Text is just another kind of node. You can interleave Elements with Text nodes. The Elements aren't 'inside' the text, they are beside it, as sibling nodes.
I see only Element::appendChild(), and Element::setTextContent() functions, but it seems it's not possible with those functions.Should be. Just append children, Text nodes or Elements.
and if it's possible, what functions I should use to read Elements & their position from content text?You don't. You read the child nodes from the parent element. Some of them will be Text nodes, some of them will be Elements. -
How to refer ?XML element tag name? in the RTF variable
Hi All,
I want to declare variable and assign the value of XML element tag to that variable.
Following are the steps:
<?xdoxslt:set_variable($_XDOCTX, MYCOUNT,1)?>
<?xdoxslt:get_variable($_XDOCTX, MYCOUNT)?>
<?if: xdoxslt:get_variable($_XDOCTX, MYCOUNT) =1?>xxx<?end if?>
In the declaration part,I need to replace 1 with some of the xml element tag value(for example : <?vendor_name?>).
But when I try to do so,I get some list of exceptions.
Please suggest how to proceed.
Thanks and Regards,
KaveriHi Pradeep,
Thanks for your response.Here my requirement goes:
for -each:
text(database value)
end for-each
This text value will continue from page 1 to N.
So for page1 I want HEADER1 and from page2 onwards,I require different header HEADR2.
By using your approach,my text which needs to be continued on different pages will not be acheived.
One more thing I got from XMLP User guide:
<xdofo:inline-total
display-condition="exceptfirst"
name="InvAmt">.
SInce all my tags are generated from Oracel reports,I am unable to use the above xml line.Is there any way to use this by modifying the syntax..
Please let me know your suggestions since this is show stopper for my report.
Thanks and Regards,

Extracting the Attributes values of an XML Element
Dear Forum Members
Please tell me any XML Function which is used to extract the Attribute value of an XML Element.
Given below
<BRKCD_STREDSWTINVIN_C Key="6708">
is an Element With some Key value.
I want to have that Key value.
Using Extract and Extractvalue I am not able to get the Attribute value.
Is there any way..
Regards
Madhu KYour xml is not really complete ;), but this should get you started:
michaels> with t as
(select xmltype('<BRKCD_STREDSWTINVIN_C Key="6708"></BRKCD_STREDSWTINVIN_C>') xml from dual)
select d.xml, d.xml.extract('//BRKCD_STREDSWTINVIN_C/@Key') key

[JS-CS4] Associated XML element...
Hi,
I'm going crazy with this.
I have a table built with XML import and I need to get the XML element associated with a cell.
I use this code:
cell.associatedXMLElement
but it always returns "null".
Obviously that cell has a content in XML structure...
Any idea why?
Thanks.Here's my script:
var my_doc = app.activeDocument;
var my_table = my_doc.pages.firstItem().textFrames.firstItem().tables.firstItem();
my_table.columns.firstitem().select();
var my_selection = doc.selection;
for(var c = 0; c < my_selection.length; c++){
if(my_selection[c].associatedXMLElement.xmlAttributes.itemByName("type").value != "house"){
my_selection[c].appliedCellStyle = doc.cellStyles.itemByName("column");
my_selection[c].clearCellStyleOverrides(true);
This will run once the table is placed through XML import
I need to check the "type" XML attribute value for every XML cell, that's why I'm performing that if statement.
Basically if a cell's XML element has a "type" attribute with "house" value the script will not apply the "column" style.
The problem is that
my_selection[c].associatedXMLElement
always return null.
The XML data structure is:
<List><Category><Table><Cell/><Cell/>....</Table></Category></List>
So I have a simple table inside a textFrame.
I know what I'm doing could sound weird, but I experienced it's the most quick way to handle a big table within ID.
Here's the background story
Thanks again. -
SAX, incor. data for XML element, XML 1.1 doc (1.0 ok) in JRE 6 (JRE 5 ok)
Hello,
for some reason, the test case below fails when driven with Java 6. Looks like, when long string data is stored in a XML element, DocumentHandler's characters() method will be provided with incorrect data.
With XML 1.0, parsing works fine in all my tests, Apache Xerces, JRE 5, JRE 6.
With XML 1.1., parsing works fine with Apache Xerces, JRE5 but not with JRE6.
I've checked it with latest JRE 6 update 4.
Anyone else xperiencing such problems with XML1.1 parsing when using JAXP bundled with Java 6?
I've tried to file a bug at bugdatabase, but for some reason I got no response for my issue - so I'm trying the forum now ;-)
Thanx for comments

}thanx, DrClap, haven't seen the "code" button for some reason, code is attached again
The output of my test is like this for JRE6 (truncated)
xml_sun 456789 This is is some text 0. 0123456789 This is some text 1.
xml_apache 0123456789 This is some text 0. 0123456789 This is some text 1.
Notice, xml_sun not only starts wrong ("0123" missing) - for some reason, the text there is not "This is some text" but "This is is some text" - very interesting in a way. I guess there's an issue with repeated text chunks ...
So, the data in my XML element is kind of changed, the length of the string is okay but the characters are "misplaced" or so :-) I thought about a problem with StringBuffer first, but the StringBuffer works fine for Apache ... so I really think there's an issue with JRE 6's parser for XML 1.1
