Definitely agree that TeX can get pretty complicated. My method (writing a converter from one TeX tag system to another) was to pre-parse using string match/replace for really simple stuff, regular expressions for the more complex and pyparsing for the really tough stuff. One thing that was surprisingly hard for me to figure out was filtering out comments. I finally just looped through the file line by line, looking for a '%' that wasn't in a verbatim environment and wasn't escaped, etc. Funny how sometimes the simplest thing can be difficult to handle. Definitely pyparsing made the job possible; I can't imagine that job without it. --Tim Arnold -- http://mail.python.org/mailman/listinfo/python-list
