Now I found out that, at least with Saxon (not sure of
others), the '#'
character is considered a comment delimiter when the 'x' flag (ignore
whitespace) is ignored. Furthermore, it does not appear
possible to escape the '#' character.
What version of Saxon are you using (and on what platform)? I think there
was a bug in this area in earlier releases but that it works correctly in
Saxon 8.8.
I tested with 8.8 and the problem indeed seems to be resolved. Thanks.
We'll update our applications.
However, I do find a new odd behavior with "\" and a space, in
conjunction with the 'x' modifier flag. Without the flag, it raises an
exception, with the flag, it makes the match fail on any input. I will
notify this on the appropriate list.
Cheers,
