Default predicates and variables in match attribute

Hi all!

Let's say we have this XML:

<frozenTreats>
<treat type="ice-cream">
<flavour>chocolate</flavour>
</treat>
<treat type="ice-cream">
<flavour>vanilla</flavour>
</treat>
<treat type="yogurt">
<flavour>chocolate</flavour>
</treat>
</frozenTreats>

My question is: can I use a variable in the match attribute of a template? Something like this:

<xsl:variable name="myPreferredTreat" select="'yogurt'"/>

<xsl:template match="treat[@type = $myPreferredTreat]">
<xsl:value-of select="concat(flavour, ' ', @type)"/>
</xsl:template>

thanks,

Rushman

It's allowed in XSLT 2.0 but not in XSLT 1.0.

Though I believe at least one XSLT 1.0 processor (Xalan) does actually allow it, despite it being illegal according to the spec.

You are right Mike. It works with Xalan if written in XSLT 1.0. I tested in oXygen editor with different processors.
