in reply to Re^2: 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

$ cat dav-rfc4918-dingaling.xml <?xml version="1.0" encoding="utf-8"?> <D:propfind xmlns:D="DAV:"> <D:prop xmlns:R="http://ns.example.com/boxschema/"> <R:bigbox/> <R:author/> <R:DingALing/> <R:Random/> </D:prop> </D:propfind> $ $ cat dav-rfc4918-allprop.xml <?xml version="1.0" encoding="utf-8" ?> <D:propfind xmlns:D="DAV:"> <D:allprop/> </D:propfind> $ $ cat dav-rfc4918-propname.xml <?xml version="1.0" encoding="utf-8" ?> <propfind xmlns="DAV:"> <propname/> </propfind> $ $ $ xmllint.exe --xpath " //*[ local-name() != 'propfind' and contains(l +ocal-name(), 'prop ') and namespace-uri() = 'DAV:' ] " dav-rfc4918-dingaling.xml <D:prop xmlns:R="http://ns.example.com/boxschema/"> <R:bigbox/> <R:author/> <R:DingALing/> <R:Random/> </D:prop> $ $ xmllint.exe --xpath " //*[ local-name() != 'propfind' and contains(l +ocal-name(), 'prop ') and namespace-uri() = 'DAV:' ] " dav-rfc4918-allprop.xml <D:allprop/> $ $ xmllint.exe --xpath " //*[ local-name() != 'propfind' and contains(l +ocal-name(), 'prop ') and namespace-uri() = 'DAV:' ] " dav-rfc4918-propname.xml <propname/> $
