RE: [xsl] Conditional extraction of data

what I wrote earlier should solve that particular problem, text nodes have a
default template which is like this
<xsl:template match="text()">
<xsl:value-of select="."/>
</xsl:template>

this is why you don't actually have to use xsl:value-of to copy text, just
applying templates will copy without doing anything else unless you've
overridden the default template.
example overriding
<xsl:template match="text()"><xsl:text>I'm overriding the default text template
woo-hoo!</xsl:text>
<xsl:value-of select="."/>
</xsl:template>
