Using XPath on JDOM

Hi,
I am looking for am elegant way to extract data from JDOM.
I tried using org.jdom.xpath.XPath but am not sure what jars I need or what needs to be initialized before XPath works.
While execution the XPath.newInstance fails..
Element result = data.getRootElement();//partner_results
try{
XPath xpath = XPath.newInstance("/partner_results/partner_result[@name=\"Amazon\"]");
result = (org.jdom.Element)xpath.selectSingleNode(data);
}catch(Exception e){}
Is there an easy way to get this ball rolling. There does not seem to be enough documentation on using XPath on JDOM
Any pointers would be really useful.
thanks
M

Thanks for suggesting Jaxen. I am now able to pull most of the data out of JDOM.
However, here is a issue I am facing with following snippet of XML. What is the correct XPath expression to extract the node MultiOperationResponse?
- <partner_results>
- <partner_result id="3" name="Amazon">
<status code="200">OK</status>
- <data>
+ <MultiOperationResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2005-07-26">
</MultiOperationResponse>
</data>
<partner_result>
<partner_results>
Here is the XPath expression
XPath expr = new JDOMXPath("/partner_results/partner_result[@name=\"Amazon\"]/data/MultiOperationResponse");
expr.addNamespace("","http://webservices.amazon.com/AWSECommerceService/2005-07-26");
I get a null when I apply the
result = (org.jdom.Element)expr.selectSingleNode(data);
Where data is the JDOM tree.
However, I can extarct the <data> node.
What is it that I am missing?
thanks a bunch
M

I feel this xml output is not like the regular xml output. Do you know why it is diffrent from the regular xml xml output? Please comment on this matter.
Thanks,
Scott Chang
What do you mean by regular xml document? Are you referring to fact that its missing a root element? if yes it can be added as below
USE AdventureWorks;
GO
SELECT
p.NameStyle AS "processing-instruction(nameStyle)",
p.BusinessEntityID AS "Person/@ID",
p.ModifiedDate AS "comment()",
pp.PhoneNumber AS "text()",
FirstName AS "Person/Name/First",
MiddleName AS "Person/Name/Middle",
LastName AS "Person/Name/Last",
EmailAddress AS "Person/Email"
FROM Person.Person p
INNER JOIN Person.EmailAddress e
ON p.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.PersonPhone pp
ON p.BusinessEntityID = pp.BusinessEntityID
FOR XML PATH('ElementName'),ROOT('RootName');
replace ElementName and RootName with whatever name you need to set for element as well as the root element

Using xpath expressions in Document-Builder

Hi all
we have re-designed our (existing) DDX-templates with the Document Builder in LC Workbench. The DDX templates are used to assemble PDFs with LC Assembler-Service.
Now my question: Is it still possible to use XPath-expression in the DDX template? Please find our example below:
The XPath expression works only if we copy&paste the DDX source code directly to the Assembler-Service property view (picture below). But referring the DDX-template doens't interpret the xpath path at run time (2nd picture below). Any help on that will be appreciated!
Works (using DDX source code directly):
Doesn't work (using DDX template):

Hi,
>
I tried to get a portion of an XML by using XPath Expressions as follows:
String xPathExpression =
"declare namespace xq='http://inti.notariado.org/indices' " +
"$this/xq:RULES/xq:RULE[@disabled]";
I think any XPath expressions which use [] are not supported in stand alone
version, but as this is not documented I could be wrong.

Using XPath for DOM traversal

This question falls into the category of 'I know it's possible, I just need to find the idom in Java'.
I'm coming from a MSFT world were the DOM-centric model of XML processing makes heavy use of XPATH for node selection. Basically using the method element.selectNodes(XPathExpresson) allows one to quickly extract the relevant subset of the parsed tree in the DOM as a nodeList. I've become accustomed to using XML for all strucutured storage that doesn't require a full database.
The W3C DOM Level 3 spec supports evaluateExpression() for this purpose, but I can't believe that Java developers are still using tree traversal waiting for the spec to be implemented. I suppose that I could use getNodesByTagName(), but this is a chainsaw, and I need a scalpel. Anyway, I'm trying to figure out how, exactly, this gets done in Java.
I figure the following are possibilities:
1) It's in JAXP and I missed it
2) One or more of the XML parsers supports XPATH as an extention
3) There's a common package that sits on top of the DOM Document.
4) There's a standard way to apply and XSLT methods to the DOM document
5) Something I've never thought of.
This is a generalized problem for me, so I can't rely on object serialization, Java-XML data mapping, etc. Any guidance would be greatly appreciated.

I've written a Config file reader for XML in java,
and it extracts values using XPath. This is
some of the code you'll need:
imports:
import javax.xml.transform.TransformerException;
import org.w3c.dom.*;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.apache.xerces.parsers.DOMParser;
import org.apache.xpath.XPathAPI;
import org.apache.xpath.objects.*;
Document doc=....;
* returns a single DOM Node from the config file.
public Node getNode(String xpath) throws ConfigException {
try {
return XPathAPI.selectSingleNode(doc, xpath);
} catch (TransformerException e) {
throw new ConfigException("Can't find '"+xpath+"' ("+e.getMessage()+")");

Using XPath to create nodes

Hi,
Obviously the main use of XPath is to query the state of an XML document... the equivalent to a "select" statement in SQL.
DOM4J has methods that allow you to use XPath as the equivalent to "insert" statements in SQL. You can specify an XPath like "/Hello/World/Value = 3" and apply this XPath to an XML document so that it creates something like this for you:
<Hello>
<World>
<Value>3</Value>
</World>
</Hello>
This is actually very useful for an investment banking application that I'm working on.
The problem with DOM4J is that it doesn't handle attributes or conditionals well. If you specify
/Hello[@name=2]/World = 3
I would expect
<Hello name=2>
<World>3</World>
</Hello>
to be produced. Instead, it produces
<Hello[@name=2]>
<World>3</World>
</Hello>
These are all simple examples. What I'm doing in real life is using XPath to insert nodes into a complicated XML document that already has a lot of structure. I'm only adding one or two elements to big documents.
Is there anything at all like this available in the JDK 1.5 release. I've had a good look, and XPath looks like it's only for queries. Is this correct?

I think this might do what you need...
// Create a dummy XML document
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputStream bais = new ByteArrayInputStream("<test><e1/></test>".getBytes());
Document doc = db.parse(bais);
// Define the XPath expression to "select" the parent element in the document
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression xpathExpression = xpath.compile("/test/e1");
// Select the parent node (should probably chuck an ex if not present)
Node node = (Node) xpathExpression.evaluate(doc, XPathConstants.NODE);
// Create and append the child element
node.appendChild(doc.createElement("newElement"));
// Convert the Document into a string
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(baos);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(source, result);
// <?xml version="1.0" encoding="UTF-8"?><test><e1><newElement/></e1></test>
System.out.println(baos.toString());

Using XPATH to extract value.

I need some help to extract the LatestFillQuantity element value using XPATH.
in Java.
I am unable to extract the value of 10000.
Please help as to what have I done wrong.?
The Document configNode contains the flwg:
<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<i:Interest >
 <i:Generation>3</i:Generation>
 <i:Extension>
 <i:Active.From/>
 <i:Order>
 <i:Status>Confirm</i:Status>
 <i:LatestFillQuantity>100</i:LatestFillQuantity>
 </i:Order>
</i:Extension>
</i:Interest>
My Java Code
private void extractValue(Document configNode)
 XPathFactory factory = XPathFactory.newInstance();
 XPath xpath = factory.newXPath();
 try{
 XPathExpression expr
 = xpath.compile("//i:Order/i:LatestFillQuantity/text()");
 Object result = expr.evaluate(configNode, XPathConstants.NODESET);
 NodeList nodes = (NodeList) result;
 for (int i = 0; i < nodes.getLength(); i++) {
 System.out.println(nodes.item(i).getNodeValue());
 }catch(Exception e){
 System.out.println("Sorry,this aint working");
 }

The nodes being parsed are namespace prefixed.
To parse a namespace node with the JDK 5.0 javax.xml.xpath package, set the NamespaceContext on the XPath object.
An implementation of NamespaceContext with a single prefix corresponding to a namespace uri:
public class NamespaceContextImpl implements NamespaceContext{
public String uri;
public String prefix;
public NamespaceContextImpl(){}
public NamespaceContextImpl(String prefix, String uri){
 this.uri=uri;
 this.prefix=prefix;
public String getNamespaceURI(String prefix){
 return uri;
public void setNamespaceURI(String uri){
 this.uri=uri;
public String getPrefix(String uri){
 return prefix;
public void setPrefix(String prefix){
 this.prefix=prefix;
public Iterator getPrefixes(String uri){return null;}
}

Copying Variables in BPEL using XPath Query

Hi,
I am new to BPEL and i want to know if it is possible to copy data from one variable to another using XPath Query in the <from> <to> tags, when the two variables are of different message types.
I am trying to create a sample BPEL that would receive a String through the receive tag tied to one partner link (WSDl) and then invoke a different webservice using the <invoke> tag tied to another partner link (WSDL) by passing the received variable.
I have pasted the BPEL File and the two WSDl files involved.
My Issue is that when I send a soap request to the BPEL, it is passed as null to the webservice invoked.
Probably because the copy tags don't work.
Please help.

Hi,
Yes, it very much is possible.
Xpath query provides a lot many data type conversion functions(string to int, string to date etc), which can be used in copying variables.

 </ns1:applicationData>
 </xsl:template>
 </xsl:stylesheet>
After this I can see the document created in the process flow as this :
 <ns1:applicationData>
 <ns1:applicationId>MMMM</ns1:applicationId>
 <ns2:ApplicationsHDRAddInfo>
 <ns3:genericFromBasePrimitive>iuoui</ns3:genericFromBasePrimitive>
 <ns4:EstimatedMarketValue>77</ns4:EstimatedMarketValue>
 <ns4:PropertyInsuranceFee>jih</ns4:PropertyInsuranceFee>

 <ns4:LoanPaidInCashFlag>cddffgd</ns4:LoanPaidInCashFlag>
 </ns2:ApplicationsHDRAddInfo>
 </ns1:applicationData>
But whenever I am trying to extract any of the output nodes I am getting an empty result. I can copy the whole dataset into similar kind of variable.
But I am unable to get individual elements using XPATH.
I tried using exslt function for node set and xslt 2.0 without avail.
The namespaces might be the culprit here . The test method in the jdev is able to output a result but at runtime the xpath returns empty .
I have created another transform where I try to copy data from the precious dataobject to a simple string in another data object .
This is the test sample source xml for the transform created by jdev while testing with all namespaces, where I try to copy the data in a simple string in another data object.

 <ApplicationsHDRAddInfo>
 <genericFromBasePrimitive xmlns="http://xmlns.oracle.com/bpm/pa/extn/types/BasePrimitive">genericFromBasePrimitive290</genericFromBasePrimitive>
 <EstimatedMarketValue xmlns="http://xmlns.oracle.com/bpm/pa/extn/headerCategories/">291</EstimatedMarketValue>
 <PropertyInsuranceFee xmlns="http://xmlns.oracle.com/bpm/pa/extn/headerCategories/">PropertyInsuranceFee292</PropertyInsuranceFee>

 <LoanCashInFee xmlns="http://xmlns.oracle.com/bpm/pa/extn/headerCategories/">LoanCashInFee295</LoanCashInFee>
 <LoanPaidInCashFlag xmlns="http://xmlns.oracle.com/bpm/pa/extn/headerCategories/">LoanPaidInCashFlag296</LoanPaidInCashFlag>
 </ApplicationsHDRAddInfo>
 </applicationData>
And the xslt
 <xsl:template match="/">
 <ns1:DefaultOutput>
 <ns1:attribute1>
 <xsl:value-of select="/fslo:applicationData/fslo:ApplicationsHDRAddInfo/custom:LoanOriginationFee"/>
 </ns1:attribute1>
 </ns1:DefaultOutput>
 </xsl:template>
This results in a empty attribute1. Any help will be appreciated .

Please delete attributeFormDefault="qualified" elementFormDefault="qualified" from your XSD

How to use XPath in the adapter framework

I am creating a XI adapter to our system.
In the adapter I want to use XPath expression.
I use the classes from javax.xml.xpath.*
This way does not work in the XI application server. (Java 1.4.2)
What is the correct way? Which packages/classes must be used?
Miklos

Hi Miklos,
The package javax.xml.xpath was introduced with Java 5 (1.5), thus it is not available in XI which runs Java 1.4.2. There are (at least) a couple of ways to use XPath in Java 1.4:
1. Use a third-party library that supports XPath, for instance Xalan-J from Apache.
2. Embed your XPath expression in an XSLT transformation, execute the transformation using classes from the javax.xml.tranform... packages (which are part 1.4) and extract the result.
Cheers,
Thorsten

Using Xpath in Receiver Determination for greater than 500

Hi,
I am trying to use Xpath in the receiver Determination step and I want to check a field which is at item level and comes multiple times(0-unbounded) greater than 500.I tried with different options per SDN blogs,Xpath functions,but still I couldn't able to get what i am trying.I want to process the message when "quantity" is greater than 500,else I want to ignore the message with no errors.
I gave like this /p1: /LIST/item[quantity>499] EX
item loop is 0-unbounded and I need to check for every quantity.I selected the check box multi line as well.
I played around different options,but still did not get what I am looking for.
please suggest in this regard ,how I need to give the expression.
Thank you,
Sri

Hi,
For validating that the item field is occuring more than 500 times you need to choose the
2.The exact XPath would be in your case *(/p1: /LIST/itemquantity[499]EX)*
This means if the 500 th occurance of the item exists then the condition satisfies that is always true for 500 and above occurance of the item.
Please revert if the suggestion proves to be helpful.
cheers,
Abhishek.

How to use XPath with Namespaces in the xml ?

Hi all,
I need to reference a certain Node in a Document using XPath notation.
The problem is the the XML Document contains Namespaces inside it
f.e.
<xn:SubNetwork id="JRANM">
 <xn:VsDataContainer id="1">
 <xn:vsDataType>vsDataAreas</xn:vsDataType>
 </xn:VsDataContainer>
</xn:SubNetwork >Using DOMXPath (from weblogic.xml.xpath)
DOMXPath xPath = new DOMXPath("xn:SubNetwork/*");
Set nodeset = xPath.evaluateAsNodeset(this.xmlRootElement);When I Iterate through the Set I can see it's empty.
(On the other hand without namespaces everything is fine.)
So how can I reference a Node that contains a namespace in it ?
Thanks a lot
Francesco

We use the following class to perform XPath Queries on our XmlBean objects.
Hope this helps,
Craig
import java.util.Set;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.apache.xmlbeans.XmlException;
import org.w3c.dom.Document;
import weblogic.xml.util.StringInputStream;
import weblogic.xml.xpath.DOMXPath;
* Class to encapsulate API specific (i.e. weblogic) XML functions
public class XmlUtil {
 * Returns a set containing objects of type reflected in the query. 
 * e.g. 
 * /saur:tree/saur:treeNode[@label='My Reports'] 
 * Returns a Set of TreeNode objects 
 * Sample Code: 
 * <code>
 * Set set = XmlUtil.executeXPathQuery( myQuery, tree.xmlText());
 * for( Iterator iter = set.iterator(); iter.hasNext();) {
 * TreeNode node = TreeNode.Factory.parse((Node)iter.next());
 * // Do whatever...

I am loading xml using xpath query bu i am stucked here.I am not able to pass the loop counter "I" into the query.Please help.
The problem is in line " 13 FROM xml_table,table(XMLSequence(extract(OBJECT_VALUE, '/BIF/SBI/SBC/flag'))) li;
" in the below block

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;

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>
</sequence>
</complexType>
</element>
<element name="processResponse">
<complexType>
<sequence>
<element name="result" type="string"/>
</sequence>
</complexType>
</element>
</schema>
This works !!!
Please let me know if this helps.
Thanks,
