XPATH problems

I use xpath to filter a xml document. When I use the xpath expressions from a main method everything works fine. But when I try to run my classes on through a servlet, the xpath returns nothing. I am using WSAD 5.0.1. Why would it not work on the server?

I am using the xalan api to access xpath features.

Xindice - XPath Problem

Hello,
I've been using Xindice DB to manage XML files. Everything seemed to work well, but then i've run in some problems concering XPath queries.
I have two "resources" (item1 and item2) for testing purposes in a collection named items. Both xml resources look like the following:
<?xml version="1.0" encoding="UTF-8"?>
<assessmentItemType title="item1" timeDependent="false"
identifier="item1" adaptive="false"
xmlns:ns2="http://www.imsglobal.org/xsd/imslip_v1p0"
xmlns="http://www.imsglobal.org/xsd/imsqti_v2p1"
xmlns:ns4="http://www.w3.org/1998/Math/MathML"
xmlns:ns3="http://www.w3.org/1999/xlink" xmlns:ns5="http://www.w3.org/2001/XInclude">
<itemBody id="itemBody1"/>
</assessmentItemType>i (e.g.) want to get the id of the itemBody element, so i use the xpath query
//itemBody/@id For a strange reason i don't get any results back.
(I tested the query with the xpath trainer on http://www.write4food.orangegear.com/xptr.html to check if my xpath query was wrong, but it wasn't)
If i just use
/* as an xpath query, i get both resources (item1 and item2), which means that some xpath queries work.
I'm fetching the data with the following code
String query = "//itemBody/@id";
XPathQueryService service = (XPathQueryService) col.getService("XPathQueryService", "1.0");
ResourceSet resultSet = service.query(query);
ResourceIterator results = resultSet.getIterator();
while (results.hasMoreResources()) {
Resource res = results.nextResource();
System.out.println((String) res.getContent());
}Has anyone an explanation for this behavior?
Thanks in advance!
Figured it out: Forgot to add the namespaces information. Now everything works fine...
XPathQueryService service = (XPathQueryService) col.getService("XPathQueryService", "1.0");
service.setNamespace("ns-prefix", "ns-url");n10e

XPath problems (or XKMS problems)

Hi,
I'm working with XKMS (XML Signature) package, and i have found some annoying problem (maybe someone has found it too and has solved it).
When i create an XPath expression to point the Signature element of my XML file and try to construct a verifier which will check that signature, i get the next error:
com.verisign.xpath.XPathException: /dsig:Signature does not contain Signature, found null

Thanks in advance. David.

I've already solved that problem. Seems that xpath expression was correct, thanks anyway. The problem was that XKMS seems not to understand Java XML parsers, so it needs its own one to understand the doc structure.
Does anyone know why does this happen? Is it a codification matter?
Thanks again.

Java XML Parser v2 xpath problem

I have a lot of trouble using the xpath functionality. I want to get the name of different elements. I'm using some xpath expressions which in my opinion should work (see http://www.w3.org/TR/xpath ), but they don't. I'm calling XMLNode.selectSingleNode.
For example :
/*/name()
name(/*[1])
name(/*)
name()
I've tried those with Saxon and they do work. Using the Oracle implementation an exception is thrown on most expressions. So what's wrong here?
Bye,
Jan

Consider this example
--- Test.java -----
import java.io.*;
import javax.xml.transform.sax.SAXSource;
import net.sf.saxon.sxpath.*;
import oracle.xml.parser.v2.*;
import org.w3c.dom.*;
import org.xml.sax.InputSource;
public class Test
public Test() {
try {
DOMParser domParser = new DOMParser();
domParser.parse(new FileReader("test.xml"));
XMLDocument document = domParser.getDocument();
InputSource is = new InputSource(new File("test.xml").toURL().toString());
SAXSource source = new SAXSource(is);
testXPathOracle(document,"count(//*)");
testXPathOracle(document,"name(/*)");
testXPathOracle(document,"name(/root)");
testXPathOracle(document,"/*/name()");
testXPathSaxon(source,"count(//*)");
testXPathSaxon(source,"name(/*)");
testXPathSaxon(source,"name(/root)");
testXPathSaxon(source,"/*/name()");
} catch(Exception e) {
System.out.println(e.getMessage());
public void testXPathOracle(XMLNode context, String xpath) {
try {
Node node = context.selectSingleNode(xpath);
System.out.println(node.getNodeValue());
} catch(Exception e) {
System.out.println(e.getMessage());
public void testXPathSaxon(SAXSource source, String xpath) {
try {
XPathEvaluator xpe = new XPathEvaluator();
XPathExpression exp = xpe.createExpression(xpath);
Object object = exp.evaluateSingle(source);
System.out.println(object);
} catch(Exception e) {
System.out.println(e.getMessage());
public static void main(String[] args) {
Test test = new Test();
--- test.xml -----
<root>
<element/>
</root>
Result is on my computer:
Unknown expression at EOF: (count(//*))[1].
Unknown expression at EOF: (name(/*))[1].
Unknown expression at EOF: (name(/root))[1].
Error in expression: '(/*/name())[1]'.
2
root
root
root
I think the xpath expressions are valid. So what's wrong?

XPATH problem in Receiver Determination

Hi Experts, I get stucked in the XPATH expression in the Receriver Determination(RD) :
The input xml (default namespace settting) is like this :
<?xml version="1.0" encoding="UTF-8" ?>
<MT_XML_SENDER xmlns="http://test.com">
<LAST_NAME>Bryant</LAST_NAME>
<FIRST_NAME>Kobe10</FIRST_NAME>
</MT_XML_SENDER>
In the RD, I tried serveral XPATH expressions :
/MT_XML_SENDER/LAST_NAME = Bryant
/MT_XML_SENDER/LAST_NAME = "Bryant"
/MT_XML_SENDER(LAST_NAME = \"Bryant\") EX
But in every case, the PI always told me it could not find the receiver, I don't know what to do........
(BTW,if I remove the condition, PI could work as desired, so it is 100% related to XPATH setting)
Thanks very very much!!!!!
Ray

You probably noticed by yourself, but in the Condition Editor, it is necessary to set the namespace to a prefix and then create the XPath expression based on that prefix. i.e.
/p1:MT_XML_SENDER/p1:LAST_NAME
And on the prefix definitions, you set it to your namespace:
p1 http://test.com
Easiest way to do it is to go through the message structure, though, since it will fill the prefix automatically as per the definition in the message type in repository.
Best regards,
Henrique.

Import Schema leads to XPath Problems

Hallo,
When using a bpel process where I have some schema definitions included, I'm not able to access the contents of variables with XPath.
<schema attributeFormDefault="unqualified"
elementFormDefault="qualified"
targetNamespace="http://service.achrist.net/price/"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://service.achrist.net/price/"
xmlns:md="http://service.achrist.net/masterdata/">
<import schemaLocation="MasterData.xsd" namespace="http://service.achrist.net/masterdata/"/>
<element name="PriceServiceProcessRequest">
<complexType>
<sequence>
<element name="item" type="md:Item"/>
<element name="supplier" type="md:Supplier"/>
</sequence>
</complexType>
</element>
</schema>
The XPath expression in the BPEL process then crosses the two namespaces
/client:PriceServiceProcessRequest/client:supplier/md:Name
When using the expression inside an assign-activity, the bpel-engine claims
"empty variable/expression result."
A workaround for this is to copy paste the xsd types into the same namespace ... but rather ugly ...
What is wrong with the imports ?

Hello,
I found one solution:
Changing the way how elements are created to:
<element name="PriceServiceProcessRequest">
          <complexType>
               <sequence>
                    <element ref="md:ItemElement"/>
<element ref="md:SupplierElement"/>
               </sequence>
          </complexType>
     </element>
... now it works as expected...

XMLBeans / XPath problem

Hi,
I'm getting java.lang.UnsupportedOperationException: This query is too complex to be processed. on the method call XmlObject[] h = doc.selectPath(queryText); I have googled the net looking for answers. I even downloaded XPath Explorer (Eclipse plugin) and my path works there for my XML file, so I'm stumped why it doesn't work in code. Please help!
Here are the assets involved:
The XML data file:
<trx:box xmlns:trx="http://mysite.com/foo">
    <trx:transaction>
        <trx:id>100</trx:id>
        <trx:handler>Dog</trx:handler>
    </trx:transaction>
    <trx:transaction>
        <trx:id>200</trx:id>
        <trx:handler>Cat</trx:handler>
    </trx:transaction>
    <trx:transaction>
        <trx:id>300</trx:id>
        <trx:handler>Mouse</trx:handler>
    </trx:transaction>
</trx:box>
The XSD file:
<xs:schema
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:trx="http://mysite.com/foo"
    targetNamespace="http://mysite.com/foo"
    elementFormDefault="qualified">
     <xs:element name="box">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="transaction" type="trx:transaction" minOccurs="1" maxOccurs="unbounded"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
   <xs:complexType name="transaction">
        <xs:sequence>
            <xs:element name="id" type="xs:string"/>
            <xs:element name="handler" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
</xs:schema>
The .xsdconfig file
<xb:config
    xmlns:xb="http://xml.apache.org/xmlbeans/2004/02/xbean/config"
    xmlns:trx="http://mysite.com/foo">
    <xb:namespace uri="http://mysite.com/foo">
        <xb:package>com.mysite.foo</xb:package>
    </xb:namespace>
</xb:config>
The code (don't yell, it's just proof of concept code):
    public Handler getHandler(String id) throws Exception
        Handler handler = null;
        BoxDocument doc = BoxDocument.Factory.parse(file);
        String nsText = "declare namespace trx='http://mysite.com/foo' ";
        String pathText = "$this/trx:box/trx:transaction[trx:id=\"" + id + "\"]/trx:handler";
        String queryText = nsText + pathText;
        System.out.println(queryText);
        XmlObject[] h = doc.selectPath(queryText); // fails here with "This query is too complex to be processed"
        Class ch = Class.forName(h[0].xmlText());
        handler = (Handler)ch.newInstance();
        return handler;
    }

java.lang.UnsupportedOperationException: This query
is too complex to be processed. In the source for XMLBeans, (xmlbeans-1.0.3/src/xmlstore/org/apache/xmlbeans/impl/store/XqrlDelegate.javaspecifically), you'll see that the rocket scientist who created this code throws an UnsupportedOperationException if it can't find the method for executing the query. The message in the exception is clearly designed to mislead his enemies.
Saxon (http://saxon.sourceforge.net/) has 1000x more robust XQuery support and they have documentation for embedding it in your app.

Dom4j xpath problem

Hello all
I have several methods in which I noticed strange behavior
Here is the example:
I create xpath as object because of performance, cause i use it on thousands of files
XPath pathSpanPodzakonska = DocumentHelper.createXPath("//span[@class='palnk']");
I found h4 element via xpath with relative path to h4 element...
That works fine so far and founds h4 element that I need to.
final Element elementH4= (Element) document.selectSingleNode("//h4[@id='someId']");
Now i need to found some element inside that h4 tag
but what I get is first element in document, outside h4 element !!!
final Node nodeSpanPodzakonska = pathSpanPodzakonska.selectSingleNode(elementH4);
That works same even if i write
final Node nodeSpanPodzakonska = elementH4.selectSingleNode("//span[@class='palnk']");
If I write code with absolute xpath that works fine when the span is directly inside of h4 but this isn't always case and cant depend on that.
And more important have some other similar methods and want to clarify what happens in this xpath implementations and how can I use it in the best way.
final Node nodeSpanPodzakonska = elementH4.selectSingleNode("span[@class='palnk']");
Danilo Cubrovic

Sorry. I will have to think about the XPath question in more detail.
As to the side by side comparison: I meant of - open source HTML parsers
http://java-source.net/open-source/html-parsers
and also of XML frameworks that support XPath (such as DOM4j vs XOM).
I am going to try HTMLParser with XOM, as I have, in informal speed testing, seen HTMLParser to be quite fast compared to others.
The reason I would like to have speed is that I am working on a Web automation toolkit:
www.mkosh.com
and it looks like I will be re-parsing the entire tree after many Javascript commands.
I would like to make this as speedy as possible. HTMLParser seems to win hands down, although if it does not work with real world HTML, that could be an issue.
I will have to test.
Thank you so much

XPath Expression Problem

Hi again,
still a newb and stillsomequestions, but hope dies at last :)
I want to extract values from a xml file which is stored in a table.
i have the following code:
COLUMN div DEFAULT
SELECT extract(value(x), '//DIV/@ ID = ''FXAC93006ENC.0001.01.00''/text()').getStringVal() AS div
FROM versuch2 x;
With this code ive got the following Error Message: ORA:31012: Not supported XPath Statement.
I tried this XPath statement in SlyXML and got a boolean:true result, so i think its not a xpath problem.
Isthere a syntax problem?
Thx for help!

The correct syntax for fetching attributes is different from what you did.
Not sure which syntax is the standard, but the Oracle Version seems more intuitive (too me). Why? Because an attribute is on the same hierachy level of the xml tag and therefore should not be queried with an additional /.
SQL> with versuch2 as (select xmltype('<doc><div id="FXAC93006ENC.0001.01.00">Test</div></doc>') xmlcol from dual)

XPath - limited logical operators?

Hi out there!
Currently I am experiencing an XPath problem, evaluating an XML file with it.
Imagine I got an XML file like this:
<xml? version="1.0" encoding="UTF-8"?>
<OverallSet>
<Set1>
<group_of_fields>
<requesting_component_command>WUZ</requesting_component_command>
<request_identifier>WUZ</request_identifier>
<request_status_indicator>APP</request_status_indicator>
<mission_number>4bubu </mission_number>
<complying_component_command>PROGRZLW</complying_component_command>
<revised_priority>5</revised_priority>
<comment_abbreviated>NONE</comment_abbreviated>
</group_of_fields>
</Set1>
<Set2>
<requesting_component_command>WUZ</requesting_component_command>
<request_identifier>WUZ</request_identifier>
<request_status_indicator>APP</request_status_indicator>
<mission_number>55</mission_number>
<complying_component_command>PROGRZLW</complying_component_command>
<revised_priority>4</revised_priority>
<comment_abbreviated>NONE</comment_abbreviated>
</Set2>
</OverallSet>
Using XPath i would like to get a Node back, not a boolean value. The Evaluations works fine for the following expression wiht any value:
//child::*[name() = 'mission_number and starts-with(descendant-or-self::*,'4') and contains(descendant-or self::*,'bubu') or name()='revised_priority' and starts-with(descendant-or-self::*,'45') and contains(descendant-or-self::*,'')]/parent::*
as soon, as i put in another AND condition, i get no result anymore - no matter which way i try. May it be name() = 'request_identifier' within the brackets, concatenated with an AND, or may it be as stand alone expression like this [name()='request_identifier'].
So my question is just if there is a certain limit to the logical expressions, and how to put in another AND condition. Do i miss something? Any suggestions welcome!
Thanks for paying attention!
Regards, Jens

Having created the XML files with the XML Spy, i use the XPath evaluation option of the tool itself. Just recognized some inconsistencies and getting confused quite frequently. But the expression should work in any case - shouldnt it?

Will the next build support loading from a string correctly?

Several weeks ago I posted a topic entitled: setDataFromDoc
and XPath problem
It dealt with restrictions when using an XML String to
populate a dataset rather than using a URL.
The simplest way of seeing what fails is to modify the RSS
demo to use a string.
The "features" area of the display doesn't then work. I've
tried setting observers but this doesn't work.
The topic has dropped off the forum without an answer.

Problem retrieving a list of values with XPATH

Hi,
I am trying to get a list of all 'Fields' (under the SubscriptionList -> EconomicIndicator -> Code) which have 'Provider' =DJ.
I am using the below xpath expression. But It is not working. I tried other variations but none of them return mulitple items.
Can some one please tell me if Iam missing something.
               XPathExpression xPathExpression= xpath.compile("/SubscriptionList/EconomicIndicator[*]/Code[Provider=DJ]/Fields");
               NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
          for (int i = 0; i < result.getLength(); i++) {

Hi DrClap,
I have a similar problem again. This time I am trying to extract a list of values from a xsd. Below is the code that I am using.
          try{
               djxsd = new FileInputStream("djei-3.1.xsd");
               XPathFactory factory = XPathFactory.newInstance();
               XPath xpath = factory.newXPath();
               SimpleNamespaceContext nsContext = new SimpleNamespaceContext();
               xpath.setNamespaceContext(nsContext);
               nsContext.addNamespace("xs", "http://www.w3.org/2001/XMLSchema");
               nsContext.addNamespace("xsi","http://www.w3.org/2001/XMLSchema-instance");
               +//String exp = "//xs:element/@name/text()";+
String exp = "/xs:schema/xs:group/xs:sequence/xs:element";
               XPathExpression xPathExpression= xpath.compile(exp);
               NodeList result = (NodeList)xPathExpression.evaluate(doc, XPathConstants.NODESET);
               FileOutputStream outputfile = new FileOutputStream("log.txt");
          for (int i = 0; i < result.getLength(); i++) {
               Element element = (Element)result.item(i);
               String output = element.getTextContent().trim();
               if(output.length() > 0)
                    outputfile.write(output.getBytes());
                    //System.out.println(output);
Highlighted in Itlalics is the actual expression that I want to use. For some reason this is not working .. it returns nothing.
The other expression works. Please let me know if there is anything wrong with the expression.

Problem in xpath reading

hi to all,
Iam using javax.xml.xpath.XPath to parse and read the xml file. It is working fine in java 1.5 version. but i want the same requirement in java 1.4. When iam using same code in java 1.4 it is throwing exceptions. Iam giving the code....
First of all iam creating XPathReader class for xpath parsing and reading.
import java.io.IOException;
import javax.xml.XMLConstants;
import javax.xml.namespace.QName;
import javax.xml.parsers.*;
import javax.xml.xpath.*;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
public class XPathReader {
private DocumentBuilder documentBuilder=null;
private Document xmlDocument;
private XPath xPath;
public XPathReader() {
initObjects();
private void initObjects(){
try {
documentBuilder= DocumentBuilderFactory.
newInstance().newDocumentBuilder();
xPath = XPathFactory.newInstance().
newXPath();
}catch (Exception ex) {
ex.printStackTrace();
public void parse(String filename){
try {
xmlDocument=documentBuilder.parse(filename);
} catch (Exception e) {
e.printStackTrace();
public Object read(String expression,
QName returnType){
try {
XPathExpression xPathExpression =
xPath.compile(expression);
return xPathExpression.evaluate
(xmlDocument, returnType);
} catch (XPathExpressionException ex) {
ex.printStackTrace();
return null;
In another class iam just creating object of XPathReader
XPathReader reader= new XPathReader();
reader.parse(....xml file path that which u want to parse......);
String expression = ....
NodeList rootNode = (NodeList)reader.read(expression,XPathConstants.NODESET);
here generally i will get NodeList object...
this code works fine in java 1.5
but it is showing exceptions in 1.4 as...
java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: No XPathFctory implementation found for the object model: http://java.sun.com/jaxp/xpath/dom
at javax.xml.xpath.XPathFactory.newInstance(Unknown Source)
I think XPathFactory is not in the 1.4. So, is there any alternative to overcome the above problem?
if any buddy knows please help me...
thanks to one and all...
