[xsl] Still battling with practical strategy for parsing escaped XML inside unescaped XML

["Karr, David" <David.Karr@xxxxxxxx>]

Ok, I'm now convinced that it's not practical to just use "disable-output-escaping" to enable parsing of escaped XML data.  It's fine if I just need to print it directly, but it does me no good if I need to do more with it.

So, I'm now trying to use a small variation of the "taggifier.xsl" script that Américo Albuquerque [melinor@xxxxxxx] provided in an earlier response to me, which just uses string searches and manipulation to produce the result.  I've changed the names slightly, and I'm trying to coerce the final result on completion.

I'm showing here my simple "data.xml" and "filter.xsl" files, along with the output I get from a "xalan" wrapper script.  It appears that I'm still having trouble with treefrag vs. nodelist (or nodeset).  Note that my code for concatenating the key and the value in the "for-each" very likely doesn't work yet, but it doesn't get there yet.

Note that I'm using Xalan 2.5.1 with JDK1.4.1 (I also tried the same test with JDK1.3.1).

Is this a possible strategy, or is this just as useless as the "d.o.e" strategy?
