Re: Svar: Re: [xml] XPath problem with namespaces

That won't work because you can have a doc that looks like this:

<a:foo xmlns:a="ns1">
      <a:bar xmlns:a="ns2"></a:bar>

Which bar element would //a:bar refer to?  Would /a:foo/a:other/a:bar find an element?
It just doesn't work.

The xmllint shell does need someway to specify prefix<->namespace mappings.  
It not very useful without that.

that was it. I knew I knew it, there was just too much info at once ;-) But why can't it simply register all 
the namespaces from the document itself in xmlXPathNewContext?

  You *must* provide the namespace declaration to the prefix used.
Read the example it shows how to bind namespaces to XPath evaluation context !
