RE: [xsl] How to concatenate/merge two independent XSLT stylesheets into ONE stylesheet?

["Michael Kay" <mike@xxxxxxxxxxxx>]

There are much more efficient ways of creating a pipeline than using "|" on
the command line, but presumably they are ruled out too.

There's no foolproof way of doing this without manually checking for
conflicting names of templates, global variables, keys etc. If you've been
very disciplined then these will all be in namespaces, and it will all be
much easier, but unless you are a very faithful disciple of Ken Holman then
this is unlikely to be the case.

You should change one of the stylesheets (or preferably both) to use named
modes on all template rules and calls of apply-templates.

Then finally you can stitch them together with

<xsl:template match="/">
  <xsl:variable name="temp">
    <xsl:apply-templates select="." mode="phase1"/>
  </xsl:variable>
  <xsl:apply-templates select="$temp" mode="phase2"/>
</xsl:template>

Alternatively, if you don't mind a product-specific solution, use
saxon:next-in-chain on the xsl:output element.
