Re: Giving values to xsl:variable by xml attribute

Unless you convert $values to a node-set (using an extension function), you
shouldn't even get the results you describe.  When you bind a variable name
to a value using template content, the data type is result tree fragment,
and most XPath operations are not allowed on rtf.  Your xslt processor may
be silently coercing rtf to node-set (which in many cases would be helpful,
but is not in accord with the current specification).  See
http://www.w3.org/TR/xslt#section-Result-Tree-Fragments.

Anyway, assuming you get $values to be a node-set, you can parameterize the
selection using a predicate to specify the name of the element, like so (I
show example using xt's node-set function on $values):

<xsl:template name="x">
    ...
    <xsl:value-of select="xt:node-set($values)/*[name() = @value]"/>
    ...
</xsl:template>

Or, from anywhere in your stylesheet (assuming just one <x> element):
    <xsl:value-of select="xt:node-set($values)/*[name() =
current()//x/@value]"/>

Hope this helps,
