stringregexp

[gcue 8]

I am trying to grab "CVS.IST.LO.NA.CUPD" from the text below

Current context: CVS.IST.LO.NA.CUPD

User: ERTTT

Name: ERTTT

Name: UT_442

creatorsName: CN=CONRLS

Given Name: Eddie

Group Membership: ACCESS_BROWFS15_TEAMS_DBA.CDS

Group Membership: PC_SUPPORT.CDS..

here's what i have so far but not quite there yet.... what am i missing?

$current_context = StringRegExp($novell_output, "($i)($s)(?x)current context[:ascii:\S]", 1, $ofs)
_ArrayDisplay($current_context)

Not even close. Try: "(?:Current context:\s*)(\S+)"

Edit: Didn't have to escape the literal colon "\:".

$current_context = StringRegExp($novell_output, "($i)($s)(?x)current context[:ascii:\S]", 1, $ofs)
_ArrayDisplay($current_context)

It looks like you can simplify things a bit:

$current_context = StringRegExp($novell_output, "(?i)current context: [:alnum:.]+", 1)
_ArrayDisplay($current_context)

Breakdown:

Changed the ($i) to (?i) because I believe it to be a typo.

Removed the (?s)(?x) because you don't need to match newlines (in fact a newline terminates the string you want), and there is not comments to worry about, and whitespace is important to matching "current context" correctly.

Based on you example, I changed :ascii: to :alnum:, to avoid weird punctuation sneaking in.

Also I changed \S to . as that was the separator in your record. I think that was the functionality you were looking for because \S duplicates the :ascii: group. \s is whitespace, which is what I think you were going for.

$ofs is optional, and doesn't appear to play into this particular case.

Hope this helps

@fulano,

I believe the offset to be a leftover from a regexp answer I made to a previous post, where I needed the feature.

@gcue,

regexp are very logical (even if I'm not the only one to admit they can be tricky at times) and the nice thing is: they never bite you, I mean physically. So don't get afraid to spend some time playing with them, experimenting from simple ones to more complex, throwing new quantifiers and constructs as you progress. RegExCoach is perfect for that.

The PCRE page link in the help page of StringRegExp is a definitive precise guide explaining everything in detail. Just forget about pure Perlisms at the end.
