Dear XML Query Working Group, Dear XSL Working Group, http://www.w3.org/TR/2005/CR-xpath-functions-20051103/ extends the semantics of the regular expressions defined in XML Schema 1.0 to allow for capture buffers; I would like to re-use regular expressions as de- fined in the candidate recommendation in a DTLL-like format, but an imporant requirement is automatic assignment of names for the captured substrings based on the index number of the parenthesized sub-expression as defined in the technical report. This is not feasible however with the current syntax as it does not allow non-capturing sub-expressions, so I would have to further extend the format which makes sharing of regular expressions and regex engines difficult. In fact, in order to re-use regular expressions as found on many web sites and programs, and as produced by many tools, one would first have to re-write them to fit into this model. I thus think the regular expression syntax should further be extended to allow for non-capturing sub-expressions using a syntax like (?:...) as is available in most other regular expression formats. regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
