[xsl] Using XSLT to add markup to a document

[Jim Melton <jim.melton@xxxxxxx>]

Gentlepeople,

I'm struggling with a problem that I fear isn't easily solved with XSLT, 
but there are many experts on this list who might be able to help.  The 
brief summary of my problem is that I want to find certain words that 
appear in paragraphs throughout a very large (XML) document and mark up 
those words without making any other changes to my document.

For example, consider a document with the following fragment:

<para>
This is a sample document that deals with markup of <emph>text</emph>.
</para>
<para>
When one applies <emph>markup</emph> to a large document, one is faced with 
a <def>time-consuming</def> effort.
</para>

If one of the words to which I wish to apply markup is "markup" and another 
is "document", then I would want the result to be something like this:

<para>
This is a sample <special>document</special> that deals with 
<special>markup</special> of <emph>text</emph>.
</para>
<para>
When one applies <emph><special>markup</special></emph> to a large 
<special>document</special>, one is faced with a <def>time-consuming</def> 
effort.
</para>

As you see from this example, I want to *add* markup to the words I have 
found where they appear in my result tree, but copy everything else in my 
document to the output tree unchanged.

I tend to use Saxon (currently using 6.5.2) as my primary XSLT engine, but 
I also have Microsoft's MSXML 4.0 (and could undoubtedly find others if 
required to do so).

Any guidance or advice?

Many thanks,
   Jim
