RE: [xsl] using document in xsl:key match...

["M. David Peterson" <m.david@xxxxxxxxxx>]

A key needs to be set up as a generic reference.  As such it wont accept
variables or the document function as values.  Simply set the values of
use and match to the elements or attributes you are trying to index and
then within your stylesheet use it with the key function within a block
of code whose context is set to the point where the values of the xpath
contained in the match and use attributes evaluate correctly.

See Jeni Tennisons site for a better understanding of how to use keys
with variables and/or the document function.

Subject: [xsl] using document in xsl:key match...

I am using the libxslt from the GNOME project
(http://xmlsoft.org/XSLT/).
I would like to confirm that this is a bug, and not a design issue.

I am trying to use xsl:key to index a set of elements from another
document.
When I try to do:
<xsl:key match="document('ed.xml')/root/sup" use="@name"/>
I get:
XPath error : Invalid expression
//document('ed.xml')/root/sup
           ^
compilation error: file tb.xml line 7 element key
xsl:key : XPath pattern compilation failed
'//document('ed.xml')/root/sup'

It appears that a // is being prepended to my XPath query, which is
causing
it to fail.  Is this suppose to be a valid construct (using document in
an xsl:key match term)?  Or is this a bug in the library?

After additional reading of: http://www.w3.org/TR/xslt#NT-Pattern
It appears this construct is not allowed.  Is this correct?
