Can I use something like :
<xsl:variable name="var" select="A/B/C|X/D/@ID" />
I think this gets interpretted as 'A/B/C' or 'X/D/@ID'
You think correctly.
I spell it out, but there may be a more succinct way.
<xsl:variable name="var" select="A/B/C/D/@ID|A/B/X/D/@ID"/>
In 2.0 you can write
select="A/B/(C|X)/D/@ID
You have to be careful with such rewrites. I believe this works for "|" but
I discovered that it doesn't work for "except": [A//B//* except A//C//*]
gives a different result from [A//(B except C)//*]. If there's anyone
listening who fancies doing some formal analysis of these expressions for an
M.Sc project, I'd love to see the answers...
