I can’t think of anything that specifically generates example XML from and XSD file in Perl. However if I were approaching the task I would start by looking at XML::Compile and XML::Pastor which both support some form of XSD -> Perl marshaling. There may be some way to boostrap their XSD parsing and build a random document generator from that.

Another, much less favorable, option is to use my own XML::Toolkit to generate objects from the XSD file and use those to build a generator for your document. This wouldn’t be trivial or even necessarily “sane”, but I think it should be possible.

There simply aren’t many tools for XSD in Perl at the moment.
