XPath and XML: Multiple namespaces
- by emragins
So I have a document that looks like
<a xmlns="uri1" xmlns:pre2="uri2">
<b xmlns:pre3="uri3">
<pre3:c>
<stuff></stuff>
<goes></goes>
<here></here>
</pre3:c>
<pre3:d xmlns="uri4">
<under></under>
<the></the>
<tree></tree>
</pre3:d>
</b>
</a>
I want an xpath expression that will get me <under>.
This has a namespaceURI of uri4.
Right now my expression looks like:
//ns:a/ns:b/pre3:d/pre4:under
I have the namespace manager add 'ns' for the default namespace (uri1 in this case) and I have it defined with pre2, pre3, and pre4 for uri2, uri3, and uri4 respectively.
I get the error "Expression must evaluate to a node-set."
I know that the node exists. I know that everything up until the pre4:under in my xpath works fine as I use it in the rest of the document with no issues. It's the additional pre4:under that causes the error, and I'm not sure why.
Any ideas?
Thanks.
