Parsing text With XSLT 3

Although there is at least one parser generator that targets XSLT, this talk is about hand-written parsers. Some difficulties will be described, along with mitigations. Some techniques made possible by XSLT 3 will be described and some examples given. Attention to debugging and testing is also given. The techniques have much wider application than formal parsing, and it turns out to be both useful and fun.
