Hello,

I've been trying to use regular expressions to apply a template to all elements ending in 'wp' but nothing has worked. The code is pasted below:

<xsl:template match="what goes here?">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:attribute name="wpno"><xsl:number count="*[@wpno]" format="0000" level="any" from="production"/><!--count counts the position of the wpno in the whole document, not by what is called in a template--></xsl:attribute>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>

You don't make it clear whether it is the element name or its value that must end in "wp". Assuming the name, write

match="*[ends-with(local-name(), 'wp')]"

It was the element name. Sorry for the confusion, and thanks very much for the help.
