Let me explain another way:
The sound a dog makes is woof and the sound a cat makes is bark.
Say I am looking for animals in the above example, then I can search
for anything that comes between "the sound" and "makes", but I don't
know what lies between those two patterns, so I cannot search for dog
or cat. What I need to do is to find something lying between two
regular expressions matchin "the sound" and "makes" and wrap that
something in an <animal> tag.
<xsl:variable name="regex" as="xs:string">(sound)(.*?)(makes)</xsl:variable>
<xsl:analyze-string select="." regex="{$regex}">
<xsl:matching-substring>
<xsl:value-of select="regex-group(1)"/>
<wrapped><xsl:value-of select="regex-group(2)"/></wrapped>
<xsl:value-of select="regex-group(3)"/>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
