Hey Don,
Aye that nailed it indeed. I won't even begin to pretend I
understand
what the '(?:,\s)*(\w+' means at the start of the expression.
Any chance you could fire a quick explanation or maybe point me in the
direction of a site that would explain it? I've scoured a few regexp sites
but alas I find it hard to not learn by samples and examples.
Thanks for your help,
Mark.

/(?:,\s)*(\w+local.xml)/.match('xpl.xml, demoUK.xml, met_local.xml,
cfg.xml')[1]
The one I sent before won't work if the filename is the first one in the
list. The only difference in this one is the first expression needs the
asterisk, but this one worked fine.

That worked for me. Give it a shot.

Subject: [Wtr-general] My regexp is too greedy!!
Have a small problem with the regular expression below.
In the line there's a There's a number of files in comma separated list.
I'm attempting to extract the name of the file that ends with
'local.xml'
i.e. in this case met_local.xml
The following ruby expression
/ (.*local.xml?)/.match('xpl.xml, demoUK.xml, met_local.xml,
cfg.xml')[1]
returns
=> "demoUK.xml, met_local.xml"
What I need returned is simply "met_local.xml".
I was hoping the space at the start of the regexp would mean I'd only
get
the value " met_local.xml" upon which I could
strip the trailing whitespace and leaved me with my file name.
I guess it's because the regexp is too greedy. Would anyone have any
idea
how I could extract just the filename ending in local.xml ?
In the last fortnight there's been a serious increase in traffic on this
list.
Would that be because of the Google mention? Great stuff. Thoroughly
deserved.
Thanks,
Mark.
