Re: [xsl] Select with multiple conditions?

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi again,

Another footnote is that even in XSLT 1.0 if we can contrive to bind the
values 'collection', 'recordgrp', 'series' and 'subseries' to XML somewhere
(for example loading them from an example document) we can then say
for-each select="*[@level=$levels]" where $levels is the set of XML nodes
with the given values.

This is more or less how we also do it in 2.0 or 3.0 with the benefit of
having $levels in a more convenient form such as a sequence of strings.

Cheers, Wendell
