I am working with a series of programs that export pure textual data as XPS files. I want to get at this text data in order to some post-processing. Currently I am using a windows based commercial product to convert the files to a text format, but this is a full blown windows app.
What I am after is a command line program that can extract text from an XPS file. I know that rolling my own is probably possible, but I am not sure where to start for that task either.
I would prefer an OSS solution but may accept another commercial product. My current commercial product does offer a $300 command line version, but that price is hurting my sense of value for what it actually offers compared to $100 for the windows based version.
I know that this is less of a programming question than a product hunting one, as there are several questions on how to create XPS, but I can't see m/any on how to process them :D
