there's never onky one way of doing anything.

For example to process stuff between a an b in

<x>
 stuff
 <a/>
 stuff <br/. you want
 <b/>
 more stuff
</x>

you can do

<xsl:template match="x">
  <xsl;apply-templates/>
</xsl;template>

<xsl:template match="x/node()[following-sibling::a]" priority="1001"/>

<xsl:template match="x/node()[preceding-sibling::b]" priority="1002"/>



That is, you don't need to explictly select the stuff you want, just lose
the stuff you don't want.
