I have XML with a bunch of different processing instructions in them;
here
is a sample:

<?Fm Condend VbV-VCO?>
<p><?Fm Condstart USB?>If you need this, do that.<?Fm Condend

</info>
For each "pair" of processing instructions (Condstart and Condend with
the
same string), I want to find all of the nodes between them.
Are the matching pairs always sibling nodes? Or can they be at different
nesting levels?
In case of siblings it sounds like an easy job for for-each-group
group-starting-with="processing-instruction('Fm')"/for-each-group
group-ending-with.
Like this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
exclude-result-prefixes="xs"
version="2.0">
<xsl:template match="/">
<results>
<xsl:apply-templates/>
</results>
</xsl:template>
<xsl:template match="*[processing-instruction('Fm')[starts-with(.,
'Condstart')]]">
<xsl:for-each-group select="node()"
group-starting-with="processing-instruction('Fm')[starts-with(.,
'Condstart')]">
<xsl:if test="self::processing-instruction('Fm')[starts-with(.,
'Condstart')]">
<group name="{.}">
<xsl:variable name="pi-end-name" select="replace(., 'Condstart',
'Condend')"/>
<xsl:for-each-group select="current-group() except ."
group-ending-with="processing-instruction('Fm')[. = $pi-end-name]">
<xsl:if
test="current-group()[last()][self::processing-instruction('Fm')[. =
$pi-end-name]]">
<xsl:copy-of
select="current-group()[position() ne last()]"/>
</xsl:if>
</xsl:for-each-group>
</group>
</xsl:if>
</xsl:for-each-group>
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="text()"/>
</xsl:stylesheet>
