Hi,
I tried what you suggested but it still does not seem
to work for me.
I get a NullPointerException on the line of code that
calls getXmlElementUsingXPath()
String xpath =
"Document/[EMAIL PROTECTED]'Primary']/LOGIN/USERID";
String primaryUserId =
getXmlElementUsingXPath(inputDocument, xpath
).getText();
Here is the method that I defined using the code that
you provided
private static Element
getXmlElementUsingXPath(Document document,
String xpathExpression)
{
try
{
HashMap map = new HashMap();
map.put("",
"http://www.nget.com/coreapps/RunDVPRequest";);
XPath xpath = new Dom4jXPath(xpathExpression);
xpath.setNamespaceContext(new
SimpleNamespaceContext(map));
return (Element)
xpath.selectSingleNode(document);
}
catch (JaxenException e)
{
System.err.println("Trouble with Jaxen...");
e.printStackTrace();
return null;
}
}
And here is the xml file that I am feeding it:
<Document
xmlns="http://www.nget.com/coreapps/RunDVPRequest";>
<LOGIN_LIST filter="Primary">
<LOGIN>
<USERID>testuser1</USERID>
<PASSWORD>somepassword</PASSWORD>
</LOGIN>
</LOGIN_LIST>
</Document>
However, when I run the same peace of code without the
xmlns namespace declaration
<Document>
<LOGIN_LIST filter="Primary">
<LOGIN>
<USERID>testuser1</USERID>
<PASSWORD>somepassword</PASSWORD>
</LOGIN>
</LOGIN_LIST>
</Document>
It works fine and I don't get any errors.
Any ideas on how I can get the code to work without
errors?
Thanks.
