The value of "." changes inside a predicate. Use current() instead, or an
explicit variable.

Subject: [xsl] selecting a node inside <xsl:for-each> fails?
Hi,
I'm trying to select a node which has attribute c set to '2',
but the selection $root//*[(_at_)c=(_dot_)] (where . is an iterator over
the sequence ('1', '2', '3')) returns nothing instead of node <b>.
Changing this into $root//*[(_at_)c=string(.)] does not work either.
The 'explicit' expression and the two expressions ('outside' and
'direct') after the <xsl:for-each> do work.
Any ideas?
I'm using Saxon B-8.7-Java.
Regards.
Rene
