Need Help??

in reply to Re: Using XPaths with XML::LibXML and XPathContext
in thread Using XPaths with XML::LibXML and XPathContext

I get it now. (I was getting confused between the namespace DAV: and the namespace DAV, duh!)

Is it compulsory to register a namespace prefix? I can seem to find no way of using a fully qualified XPath. For a namespace NS calling registerNs(NS, NS) works. Is that the only way?

If you want to use a prefix in xpath, a prefix that doesn't occur in the xml, you have to register it

You don't have to use a prefix in xpath, just write longer xpath

//*[ local-name() != 'propfind'
     and contains(local-name(), 'prop')
     and namespace-uri() = 'DAV:' ]

It all works the same
