Hi,
My problem is "I have to upload a big XML File into a relational master child model of hierarcy=5,but the struture of the xml is not as per the Data Model".I am using the xpath approach in PL/SQL because there is no other way I can get this done.Can you tel me how can I do this effeciently using this approach.Secondly,How can I increase the performance in this scenarion ?
Thanks a Lot !!!

Hi Marco,
Thanks for your advice.
Please tel me how canI use Xmltype view to come out of this problem.As I already mention that the xml tree is not per the Data model and the nodes name is also differenr so how can I do this.I don't know java but can handle pl/sql.

Count multiple nodes in XML using xPath

Hi',
How to count the CUSTSERIAL node in the below XML using xPath.
<missingICCRec>
<MissingField xmlns="http://www.Google.com/MissingFields/v1.0">
<CUSTSERIAL xmlns="http://Google.com/InboundService">23809002RN</CUSTSERIAL>
<CUSTSERIAL xmlns="http://Google.com/InboundService">23809003RN</CUSTSERIAL>
<CUSTSERIAL xmlns="http://Google.com/InboundService">23809004RN</CUSTSERIAL>
</MissingField>
</missingICCRec>
Thanks
Yatan

Yatan,
I created a simple BPEL with assign to count the node. Using ora:countNodes() function is throwing exception but when i tried with count() it works.
XSD seems to be valid. Only you need to have the function as below.
count(bpws:getVariableData('inputVariable','payload','/client:process/client:missingICCRec/client:MissingField/client:CUSTSERIAL'))
XSD Used:
<?xml version="1.0" encoding="UTF-8"?>
<schema attributeFormDefault="unqualified" elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/PIMtoRPASAmendment/BPLENodeCount/BPLENodeCount"
xmlns="http://www.w3.org/2001/XMLSchema">
<element name="process">
<complexType>
<sequence>
<element name="missingICCRec">
<complexType>
<sequence>
<element name="MissingField">
<complexType>
<sequence>
<element name="CUSTSERIAL" maxOccurs="unbounded" type="string"/>
</sequence>
</complexType>
</element>
</sequence>

</complexType>
</element>
<element name="processResponse">

This works !!!
Please let me know if this helps.

Write XML using XPath

Hi,
I have a problem. I need to WRITE a XML using XPath.
Supose that XPath String : "/clients/client/name"
Equivalent XML :
<clients>
<client>
<name></name>
</client>
<clients>
Please, helpme ...
The XPath Strings are dinamic, there are lot of combinations.
Is there an API (free ?) that support this ?
Thankz

Normally XPath is used for searching existing XML documents, not for creating new ones. So it's unlikely that anything exists to do what you ask. But not impossible, people do the strangest things. Have you searched Google?
Of course you realize you can't use arbitrary XPath expressions here, for example what would you do with a predicate?

Creating New XML using xPath

Hi,
I wanted to know if an XML Document created in the Database using xPaths. I mean, I don't want to creat any XML file on the OS in the first place. I want to create an XML using a table containing xPaths. Can this be done in XDB ?
Thanks in Advance,
Piyush

Hi Piyush
I don't see how you can create a XML document via xpath!?!? xpath it's only used to reference data in an XML document...

Creating XML using XPath

Hello,
I want to creat XML document using Dom and XPath, as per my knowledge goes I can't create it using XPath {I may b wrong, if I am then pls tell me know :-) }.
If there doesn't exists any thing like this I am thinkin of wrapping a class {say its XPathProcesserDom} which takes the XPath querry and internaly creates XML Document and returns on request. Is this a good idea :-)
waiting for comments :-)....
thanks and regards,

Read xml using xpath in java

Hi ALL,
I have a xml as follows:
<AAA>
<BBB>
<CCC>xyz</CCC>
<DDD>abc</DDD>
</BBB>
</AAA>
Now using any of the java class, i just need read the value of "CCC" as follows:
(i.e using xpath i need to read the value)
String val = x.somemethod("/AAA/BBB/CCC");
Thanks!

In case you're curious - here's the dom4j equivalent of dvohra09's sample code.
SAXReader saxReader = new SAXReader("org.apache.xerces.parsers.SAXParser");
Document doc = saxReader.read(source); //Where source is your file, input source, input stream, reader, or url
String value = doc.valueOf("//AAA/BBB/CCC"); //Result given the xml from OP = 'xyz'OK - not much difference with this simple example but if you haven't settled on an API, dom4j is worth looking at (IMHO).

How to use Xpath to query elements loaded from different xml docs?

I have a big DBLP XML doc (95mb), to load into the container, i splitted the doc into many small xml docs by the publication types, such as articles, books, inproceedings, etc.
I tried to use xpath query such as
query 'collection()/dblp[article/author]/book[title]'
I got empty answers.
but if i use XQuery such as
query 'let $r:=collection()/dblp,$a :=$r/inproceedings/author
for $l2 in $r/book
where $a and $l2/title
return <result> {$l2}{$a}</result>'
i got answers. However, if i remove {$a} from the return clause, i still got empty answers.
is there any problem with my Xpath query and flwor Xquery?

xiaoying

Hi John,
Following is the procedure i have used to load the xml docs (after the indexes have been created):
private static void loadXmlFiles(File path2DbEnv,String theContainer, File file) throws Throwable {
 //Open a container in the db environment
 XmlManager theMgr = null;
 XmlContainer openedContainer = null;
 myDbEnv env;
 try {
 env = new myDbEnv(path2DbEnv);
 theMgr = new XmlManager(env.getEnvironment(), new XmlManagerConfig());
 //use node container
 theMgr.setDefaultContainerType(XmlContainer.NodeContainer);
 try{
 openedContainer = theMgr.createContainer(theContainer);
 }catch (XmlException e){
 //if the container alreay exist, then open it;
 openedContainer = theMgr.openContainer(theContainer);
 //Get an update context.
 XmlUpdateContext updateContext = theMgr.createUpdateContext();
 String theFile = file.toString();
 String docName=file.getName();
 //Get the input stream.
 XmlInputStream theStream = theMgr.createLocalFileInputStream(theFile);
 System.out.println("Adding " + theFile + " to container " +
 theContainer);
 // Do the actual put
 openedContainer.putDocument(docName, // The document's name
 theStream, // The actual document.
 updateContext, // The update context
 // (required).
 null); // XmlDocumentConfig object
 System.out.println("done.");
 //XmlException extends DatabaseException, which in turn extends Exception.
 // Catching Exception catches them all.
 } catch (XmlException e){
 System.err.println("Error loading files into container " + theContainer);
 System.err.println(" Message: " + e.getMessage());
 //In the event of an error, we abort the operation
 // The database is left in the same state as it was in before
 // we started this operation.
 throw e;
 finally {
 cleanup(theMgr, openedContainer);
Unfortunately, i waited for around 20 hours 148mb doc was not loaded; so i gave up.
Could you please give me some suggestions on how to load the large doc efficiently ? thanks.
regards,
xiaoying

Adobe Designer 7.0 - XML parsing error when data connection to XML with UTF-16

Hi all
 
 I need to change my data connection xml file to use UTF-16 instead of ISO-8859-1. When I connect the file with the UTF-16 encoding, I receive the following error
 
 Invalid XML: Xml parsing error: encoding specified in XML declaration is incorrect (error code 19) ..
 
 The XML declaration is:
 <?xml version="1.0" encoding="utf-16"?>
 
 I am able to succesfully set the encoding to "UTF-8". UTF-16 should also be possible.
 
 Has anyone seen this error before ? How can I resolve this ?
 
 Thanks in advance
 
 Bilal Haniff

Thank you, expert, for your quick reply.
Described problem got solved: we noticed later that the extra text only appears for users using Adobe professional 7.0, 'normal' users with adobe 8.0 reader don't get the extra text, so that is ok for us.

How to remove elements/attributes from XML using Xpath in XSLT ??

Hello ,
Is there anyway or method of Xpath from which I can delete the elements and attributes from XML at runtime ??
Like I have such XML and I have to remove per attribute highlighted below
<person per="and">
<e:emp a="ir" b="ad" >
</e:emp>
</person>
And want a result like this
<person>
<e:emp a="ir" b="ad" >
</e:emp>
</person>
Thanks

To achieve this you can use the bpelx:remove function: http://download.oracle.com/docs/cd/E12483_01/integrate.1013/b28981/manipdoc.htm#CIHJBJFD
your assign will look like:
<bpel:assign>
<bpelx:remove>
<target variable="person" query="/person/@per" />
</bpelx:remove>
</bpel:assign>

Melvin

Insert Node into XML using XPATH

Hi,
I'm having problems inserting a node into a XML. After getting some attributes from the CRC result i'd like to store them in a temp xml variable.
After that the parent node of the attributes should be inserterd in a goal XML with a repeating node structure.
Whats the right way to set a node to a certain position in the goal XML?
Now the only thing i'm getting is erros about transaction:
Caused by: javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: a307d1e:fd15:4d35c503:1351f50 status: ActionStatus.ABORT_ONLY >
at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectio nManager.java:304)
at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnec tionManager2.java:396)
Etc..
Thx!

You can always append new nodes which has a unique tag name (this won't get overwritten).
Which means, each time when you add a node, it should have tag name which has not already present within the same parent node.
Later you can replace the tag name with the actual name by using XSL transformations.
I've tried this in one of my project and worked fine.

Retrieve records based on condition from xml using XPATH

Hi all,
I have a table form_content where there are two columns - form_content_id (numeric) and xml_content (clob). The structure of xml_content is
<RAF xmlns="http://www.abnamro.com/WCS/GCEG/KRT">
<XBorderRAF>

</ClientProfile>
</XBorderRAF>
</RAF>
I want to retrive all form_contant_id from form_content table where country is 'GB' inside RegisteredAddress tag.
I am able to retrive all form_content_id with country value using below query,
SELECT form_content_id,
extractValue(xmltype(xml_content),'/RAF/XBorderRAF/ClientProfile/RegisteredAddress/@country', 'xmlns="http://www.abnamro.com/WCS/GCEG/KRT"')
as registerAddress
from
form_content
but I am finding it difficult to reterive records based on any condition..
SELECT form_content_id,
extractValue(xmltype(xml_content),'/RAF/XBorderRAF/ClientProfile/RegisteredAddress/@country', 'xmlns="http://www.abnamro.com/WCS/GCEG/KRT"')

where
(extractValue(xmltype(xml_content),'/RAF/XBorderRAF/ClientProfile/RegisteredAddress/@country', 'xmlns="http://www.abnamro.com/WCS/GCEG/KRT"')='GB'
Please help me to resolve this problem. ....
Thanks

Ok, thaks to all who looked this query, I found the answer
select form_content_id

Try this code, just keep a reference to your root node so you can keep appending children to it:
DECLARE
xmlDoc xmldom.DOMDocument;
xmlNode xmldom.DOMNode;
xmlNode1 xmldom.DOMNode;
xmlElem1 xmldom.DOMElement;
xmlElem2 xmldom.DOMElement;
xmlText xmldom.DOMText;
CURSOR cur_emp IS
SELECT *
FROM emp;
--WHERE empno = 7369;
row_emp emp%ROWTYPE;
BEGIN
xmlDoc := xmldom.newDOMDocument;
xmlNode := xmldom.makeNode(xmlDoc);
xmlElem1 := xmldom.createElement(xmlDoc,'root');
xmlNode := xmldom.appendChild(xmlNode,xmldom.makeNode(xmlElem1));
OPEN cur_emp;
LOOP
FETCH cur_emp INTO row_emp;
EXIT WHEN cur_emp%NOTFOUND;
xmlElem2 := xmldom.createElement(xmlDoc,'name');
xmldom.setAttribute(xmlElem2, 'empno',TO_CHAR(row_emp.empno));
xmlNode1 := xmldom.appendChild(xmlNode,xmldom.makeNode(xmlElem2));
xmlText := xmldom.createTextNode(xmlDoc,row_emp.ename);
xmlNode1 := xmldom.appendChild(xmlNode1,xmldom.makeNode(xmlText));
END LOOP;
CLOSE cur_emp;
xmldom.writeToFile(xmlDoc,'c:\xmltest1.txt');
END;

Forming XMLs using XML beans

Hi ,
I am forming XMLs using XMLBeans whose XSDs been provided.
The tag values are coming from the database which I am querying.
and then adding the various tags as per the XSD.
In the End,I am using the ,doc.toString() where doc is the Document object as per the XSD.
and then writing it to a file.
I want to know ,what limitations can this method have or what might be a better way.
Will there be a restriction on the size of the xml being formed??
Thanks in Advance
