Hello,
is there any possibility to test if there is a specific XPath Node in an XML
Document.
For Example:
I've got an Document A which contains the specific XPath
(Root//namespace:Element//namespace:@id)
And I've got an Document B which contains this specific XPath not.
I tried an
[JAVA]
if ( doc.selectSingleNode("//Root//namespace:Element//namespace:@id") != null )
[/JAVA]
but didn't really expect to get it work.
I got the following exception:
"XPath expression uses unbound namespace prefix"
So it is and namespace problem again. I tried the same JAVA code for very
simple XML without any Namespace an it works.
The XML:
[XML]
<TEST>
<A>
</A>
<B>
<C>
TEST
</C>
</B>
</TEST>
[XML]
And the JAVA-Code:
[JAVA]
if ( doc.selectSingleNode("//TEST//B//C") != null ){
System.out.println("Dokument1");}
else
{System.out.println("NO");}
[/JAVA]
With the XML I got "Dokument1" with another testXML I got "NO". Even with
namespace XML I got "NO" then.
The problem is: I can't leave out the namespace.
A possible (but untestet solution until now) could be to temporarilly insert
the namespace (with JAVA) in the XML which I want to test and afterwards to
delete it. Because there are only about 20 possible namespaces it would be OK.
But I'm not sure if it would work and I don't think it would be the best
variant to do so.
So maybe you got any solution how I could test an XML for an specified XPath.
Thanks and best regards,
André
