Re: [xsl] Recursively link XML blocks

["Mitch C. Amiano" <Mitch.Amiano@xxxxxxxxxxx>]

Will this do?

I took the liberty of creating a sample WF doc from your fragment:

<?xml version="1.0"?>
<recursivecompose>
...
<element_A>
     textA textA textA
     <insert>element_B</insert>
     textA textA textA
</element_A>

<element_B>
     textB textB textB
     <insert>element_C</insert>
     textB textB textB
</element_B>

<element_C>
     textC textC textC
     textC textC textC
</element_C>
....etc.
</recursivecompose>

Then, assuming I *don't* know exactly what the element structure may be,
You may be able to use following:: or another XPath to improve upon the
//*, if you
can make a guarantee about the element structure.

The first apply-templates processes "element_A" explicitly. You could
alternatively
test for an attribute value, or for the first element child - whatever
you know 
that points to the root of your compositional heirarchy. 

Note that this puts a steep price on the user, should they fail to avoid
a loop 
in the linking. If, for instance, you <insert> element_C into itself,
the XSLT
engine may keep recursing until it dies. (Saxon 6.4.3 did.)

<?xml version="1.0" ?>
<xsl:stylesheet 
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   version="1.0"
>
<xsl:output method="text"/>

<xsl:template match="/*">
   <xsl:apply-templates select="element_A" />
</xsl:template>

<xsl:template match="insert">
   <xsl:apply-templates select="//*[local-name() = current()]"/>
</xsl:template>

</xsl:stylesheet>
