Re: Processing two documents, which order?

I have two xml documents.
The first is a list of marked up words (1),
the second a 'normal' xml document (2)

For each occurrence in 2 of a word from 1
I need to mark up the word with<property>  </property>

Which order is anywhere near optimum?
Document 1 has about 300 words,
Document 2 is 33,000 lines.

This is the template to do the work

<xsl:template match="*">
     <xsl:param name="property" as="xs:string"/>
     <xsl:analyze-string select="." regex="({$property})[\s\p{{P}}]">
       <xsl:matching-substring>
<!--	<xsl:message>match on [<xsl:value-of
select='regex-group(1)'/>]</xsl:message>  -->
<property><xsl:value-of
select="regex-group(1)"/></property>  </xsl:matching-substring>
       <xsl:non-matching-substring>
	<xsl:copy-of select="."/>
       </xsl:non-matching-substring>
     </xsl:analyze-string>
   </xsl:template>

but I'm hesitating as to which loop sequence will work best?
