RE: parsing post script

ps to html
Well you are going to have a problem if you are expecting to 'bring in' a
postscript file into an xslt transform. For example, the document() function
will whine because it needs well formed xml. In xslt 2.0 there is an
unparsed-text() function which would bring in the file, I believe ( use
latest saxon to exp the delights of XSLT 2.0 ).

If you could just take the contents of a ps file and wrap it with a root
element that still might be an issue, as I once had the pleasure of actually
programming something rather complex in postscript ( and yes David is right,
it's a fully featured language )....and I think you would end up having to
use d-o-e or CDATA[].

Just because XSLT is good at a job, doesn't mean it will be good for all
jobs. I would suggest maybe, if you are mining content, to convert ps to
html ( use http://webdesign.about.com/cs/htmlconverters/ ) and tidy it up
using html tidy, then bringing in the data.

Actually I dont need to render a PS file, but instead I've got to parse an
existing file and try to make sense out of it, as in, I should be able to
extract the data.
How tough would that be with XSLT and what other approach could I follow.
Right now, I'm manually reading the values enclosed in brackets()... which
is only a hack to get to the data...
The will to do, the soul to dare
