This _would_ be useful. However, to be useful, it would have to support: * Regular expressions. * Complex data types, especially things like hash tables. * Some form of "reference"-like lookahead. * Context-sensitive code based on the current SGML state. These are the things that I use every day. Converting from legacy (or as I have recently heard it called, "heritage") data to XML is not simple. If the source is very consistent, you're fine. Otherwise, it's always a struggle, in which you use every tool in your toolbox. | I have Omnimark programs which take a great | deal of processing power (I'd hate to see the | Perl equivalent).

Omnimark is actually pretty good. On the basis of the speeds reported on this mailing list, I would rate it quite fast, especially on large data sets. But of course, if you're doing a complex conversion, then your code is going to be slow. Fact of life. | I'm reading this that you are more or less | doing a YACC thing?
