Re: [xsl] Find several different attribute values on many elements

["Piez, Wendell A. (Fed) wendell.piez@xxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Dan,

Martin's question re: version is important because matching atomic values, not
nodes, is something we've only been able to do since ... five years ago now?
I.e., it requires XSLT 3.0.

Under XSLT 2.0 or (blessings upon you) older techs, other methods are better
anyway such as what Ken describes...

Cheers, Wendell

At this point you have created a sequence of (distinct) atomic values of the
contents of all elements in the collection so you are basically dealing with
strings (or other atomic values);

therefore doing an apply-templates without a select here, which then defaults
to try to process the child nodes of the context item (which is not a node)
doesn't work out.

Is that Saxon Java or which XSLT processor?
