Re: [xsl] Comments in XPath / XSLT regular expressions?

[Abel Braaksma Online <abel.online@xxxxxxxxx>]

Hi Frans,

You are right, it's there,  I didn't notice this regex flag before.

But it  does not allow for comments in the construct, it allows only for 
extra whitespace. And I need comments, otherwise the extra whitespace 
helps only a bit.

Cheers,
Abel
