This looks like a standard grouping problem: use Muenchian grouping as per

Subject: [xsl] Sorted headers of multiple occurance child nodes
Using Saxon 6.5.2 to process XSLT 1.1
I would like to write sorted headers of /record/node values
whose values
may occur more than once in a document. I'm having a pretty
tough go of
conceptualizing how to accomplish this. I've checked the xsl-list
archives, and other online resources, but I haven't found anything
usefull. Any advice would be much appreciated.
Here's dummy XML source, to demonstrate the challenge:
<tableOfContents>
<record>
<author>Mr. Jones</author>
<title>An article by Mr. Jones</title>
<journalTitle>Journal of Oceanography</journalTitle>
<subject>Oceanography</subject>
</record>
<record>
<author>Ms. Smith</author>
<title>An article by Ms. Smith</title>
<journalTitle>Oceanic Reviews</journalTitle>
<subject>Oceanography</subject>
</record>
<record>
<author>Mr. Turner</author>
<title>An article by Mr. Turner</title>
<journalTitle>Journal of Volcanology</journalTitle>
<subject>Volcanology</subject>
</record>
<record>
<author>Dr. Love</author>
<title>An article by Dr. Love</title>
<journalTitle>Modern Psychology</journalTitle>
<subject>Psychology</subject>
</record>
<record>
<author>Ms. Walker</author>
<title>An article by Ms. Walker</title>
<journalTitle>Volcanos and Stuff</journalTitle>
<subject>Volcanology</subject>
</record>
</tableOfContents>
The objective is to produce the following output. Markup and
whitespace
are incidental, I'm concerned with outputting headers and
sorting on the
subject node value, where the value may occur multiple times in the
input XML.
<html>
<h1>Table of Contents</h1>
<h2>Oceanography</h2>
<p>Mr. Jones, <b>An article by Mr. Jones</b>, <i>Journal of
Oceanography</i></p>
<p>Ms. Smith, <b>An article by Ms. Smith</b>, <i>Oceanic
Reviews</i></p>
<h2>Psychology</h2>
<p>Dr. Love, <b>An article by Dr. Love</b>, <i>Modern
Psychology</i></p>
<h2>Volcanology</h2>
<p>Mr. Turner, <b>An article by Mr. Turner</b>, <i>Journal of
Volcanology</i></p>
<p>Ms. Walker, <b>An article by Ms. Walker</b>, <i>Volcanos and
Stuff</i></p>
</html>
Again, any help would be mucho appreciated.
