Re: document identity in xpath : was RE: [xml-dev] XPath and a continuous, uniform information space

( I am not quite sure of the later ... is doc("x" ) == doc("x") ? )

Yes.  From the XSLT 1.0 spec, 12.1:

 

Two documents are treated as the same document if they are identified by the same URI. The URI used for the comparison is the absolute URI into which any relative URI was resolved and does not include any fragment identifier. One root node is treated as the same node as another root node if the two nodes are from the same document. Thus, the following expression will always be true:

 

generate-id(document("foo.xml"))=generate-id(document("foo.xml"))

 

-----------------------

 

This was confusing me why this would be in XSLT not in XPath (i.e fn:doc() is declared in XPath so both  XSLT and XQuery can use them.
