Darrell,

Yep. Actually, just this morning.

Check out the thread "[xsl] Constructing hierarchical XML from a flat XML-tag sequence using XSLT", which Mike Kay and Tom Schutzer answered.

It's also in the FAQ: check out http://www.dpawson.co.uk/xsl/sect2/flatfile.html.

Basically it's a grouping problem. Your choice is whether to select nodes based directly on their relative positions in the flat (non-)hierarchy, or whether to do effectively the same thing using keys (which is good if the case is complex, but it doesn't look as though yours is).

Adapting Mike's solution from earlier today to your case:

<xsl:template match="a">
  <div>
    <xsl:copy-of select="."/>
    <xsl:copy-of select="following-sibling::*
         [generate-id(preceding-sibling::a[1])=generate-id(current())]">
  </div>
</xsl:template>

Make sense?

Cheers,
Wendell

hello xsl list,

this problem has me scratching my head, i do not require a total solution, but perhaps a hint. I have run into mismatched tags quite a bit, i am thinking i have to use position()?

a new <div> is required every time an <a> is encountered

surely this list has seen this before?

thank you in advance.
