If it's a performance question then the answer depends on which processor
you're using. There's unlikely to be a big difference, and you'll only find
out which is faster by measuring it. In Saxon there's almost certainly no
difference, since a template rule with match="a|b" is essentially compiled
into two rules match="a" and match="b" that point to the same template body.
It might be fractionally faster to do match="*[(_at_)type=('a','b')]" (that's
2.0
syntax) but I doubt it's noticeable.

Subject: [xsl] Excluding text fragments
Hi,
we have text in HTML as a part of our documents. Additionally we use
attributes to express several special semantics of the HTML elment.
Dependant on the value of such an attribute we want to
exclude the text
fragment in the output.
So, i have the following xsl:
...
<xsl:template match="*[(_at_)type='a'] | *[(_at_)type='b'] | ...">
</xsl:template>
Instead of this the following would be possible:
<xsl:template match="*[(_at_)type='a']">
</xsl:template>
<xsl:template match="*[(_at_)type='b']">
</xsl:template>
...
Which is the best (most efficient) way to exclude such text fragments?
Best Regards
Thomas.
