I've got an old application which accepts orders via tagged text input

Something like:

etc...

I've looked at updating it to handle xml a number of times, but I've
looked at the available parsers in the past (expat etc), and got
nowhere.

As I recall, I couldn't get expat to compile - did it require gcc rather
than decc? Interesting that Bob recommends the hp offering, but Hoff
couldn't get it to work.

I grabbed the latest version of expat from

http://sourceforge.net/projects/expat/

and it compiled fine on VMS 8.3 (up to date with ECOs). See the file
[.vms]README.vms in the distribution for compilation instructions.

Documentation can be found in [.doc]reference.html

FWIW, the downloadable file came as expat-2.0.1.tar.gz - To save mucking
around on the VMS side, I unpacked it on my Mac and built a zip file
there; then used unzip on on that on VMS.

From my reading of the website, the hp offering only supports Java and
C++; Unfortunate if you don't have a C++ compiler and don't want to go
the Java route.

Suggests that I'm not the only one struggling.
There seem to be a lot of different ways to achieve the same thing with
xml (xslt, sax, dom, ...) and pretty thin documentation on all of them.

And all the examples I have found are in C, not 100% helpful for those
wishing to use another language.

Sounds like my best bet might be libxslt, preprocessing the xml into my
'legacy' format, then feeding into the original program.

Any reason why libxslt in particular?

Possibly a DTD to specify the new format to business partners.
