You can't. One method you can use in this situation, though, is to
define a key that can get you from a name to a column (child of the
Columns element):
<xsl:key name="columns" match="/Table/Columns/*" use="name()" />
Then you can do:
<xsl:template match="Row/*[key('columns', name())]">
...
</xsl:template>
In general it's a bad idea to use complicated conditions like this
within patterns; you'd probably be better off having a general
template for all elements within Row elements, but only applying
templates to those that share a name with a column:
<xsl:template match="Row">
<xsl:apply-templates select="*[key('columns', name())]" />
</xsl:template>
<xsl:template match="Row/*">
...
</xsl:template>
Cheers,
Jeni
