I modified my input document slightly:

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

Here is how I have implemented Michael's stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 	<xsl:output indent="yes"/>

 	<xsl:template match="/">
 	<xsl:template match="*[processing-instruction('Fm')[starts-with(.,
 		<xsl:for-each-group select="node()"
test="self::processing-instruction('Fm')[starts-with(., 'Condstart')]">
 				<group name="{.}">
 					<xsl:variable name="pi-end-name"
select="replace(., 'Condstart', 'Condend')"/>
select="current-group() except ."
group-ending-with="processing-instruction('Fm')[. = $pi-end-name]">
test="current-group()[last()][self::processing-instruction('Fm')[. =
select="current-group()[position() ne last()]"/>
 	<xsl:template match="text()"/>

Here is my output:

<?xml version="1.0" encoding="UTF-8"?>
   <group name="Condstart VbV-VCO">
      <p>For this, use <b>that </b>to do that.</p>
   <group name="Condstart USB">If you need this, do that.</group>

This is close, but I don't want to lose any elements from the output, like
the parents of the processing instructions (<info>, <p>). Also, I am not
picking up my last <p> element.

So which output do you want for that input sample? Do you want to generate two documents, one containing the groups for the processing instructions, the other copying the input, or do you want to mix the input with the groups? In the last case, how exactly?

I am sure we can adapt the code once we know exactly which result you want, but currently I am not sure how that result is supposed to look like.
