Re^7: RegEx for OpenOffice::OODoc as in $doc->selectElementsByContent()

It's not entirely clear to me why I need the surrounding parenthesis

The (?options:pattern) syntax is normally used in a larger regex to apply options to just a part of the whole expression:

/The (?i:internet)/

applies case-insensitivity to just "internet", but not "The"

Most Perl regex options can be used this way.

Most Perl regex options can be used this way. [Emphasis Added] But you have to be careful to distinguish between pattern options and operator options. We just had a long discussion with perl-diddler about this. For info on the `(?options:pattern)` non-capturing grouping, see Extended Patterns in perlre and Non-capturing groupings in perlretut. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

Thanks for the tip. I think I've run into that issue before and your observation would have come in handy. I'm sure I'll see the need again. Thanks again... Thanks, EigenFunctions OpSys: Win7 Professional/Home Premium x64 Service Pack 1	[reply]
