But it's free enough to support a bit of a workaround, even
if you have no schema:
<xsl:variable name="comment-elements"
select="//comments//(h1|p|b|i)"/>
<xsl:template match="*[exists(. intersect $comment-elements)]">
...
</xsl:template>
I think this should work.
Yes, but it might have fairly horrible performance.
I don't know how other processors work, but with Saxon, patterns are a lot
more efficient if they identify the element names that match, because Saxon
basically does a hash lookup on the node kind and then on the node name. Any
match="*" pattern gets tested against every node; and in this case that will
involve a serial search through the list of h1|p|b|i elements, which is
distinctly O(n^2). Not worth the savings in keystrokes.
