[GSoC] XPath namespaces

[Varuna Jayasiri <vp...@gmail.com>]

I need to clarify somethings about how namespaces are handled in XPath. I
tried searching through tutorials and specifications but still have a few
doubts.

Can you please let me know how expressions such as *** are and *ns:** are
handled when there are namespaces in the XML.

e.g.
*XML*
<ns1:node xmlns:ns1="test">abc</ns1:node>
<node>abc</node>

XPath  1
*

*should this select node* with namespace

XPath 2
ns:*

should this select node without namespace


Please also advise me if there's anything I'm missing out here

Thank you

(Assuming that you meant to say "//*")
Yes it should.

(assuming "//ns:*")
No.

However, if you are selecting a particular node, it should behave in a
different manner. For examples:

"//node" should result in only the second node and "//ns:node" should result
in only the first node.

HTH,
