regular expression match numeric value

Question

I'm trying to match a pattern:

show_clipping.php?CLIP_id=*

from:

a href="javascript:void(0);" onclick="MM_openBrWindow('show_clipping.php?CLIP_id=575','news','scrollbars=yes,resizable=yes,width=500,height=400,left=100,top=60')">some text</a>

where

can be only numeric values(eg: 0, 1 , 1234)

the result has to return the whole thing(show_clipping.php?CLIP_id=575)

what I've tried:

show_clipping.php\?CLIP_id=([1-9]|[1-9][0-9]|[1-9][0-9][0-9])

but my attempt would truncate the rest of the digits from 575, leaving the results like:

show_clipping.php?CLIP_id=5

How do I match numeric part properly?
Another issue is that the value 575 can contain any numeric value, my regex will not work after 3 digits, how do i make it work with infinit amount of digits

You didn't specify what language your are using so here is just the regex:

'([^']+)'

Explanation

'       # Match a single quote
([^`])+ # Capture anything not a single quote
'       # Match the closing single quote

So basically it capture everything in single quotes, show_clipping.php?CLIP_id=5 is in the first capture group.

See it action here.

To only capture show_clipping.php?CLIP_id=5 I would do '(.*CLIP_id=[0-9]+)'

'        # Match a single quote 
(.*      # Start capture group, match anyting
CLIP_id= # Match the literal string
[0-9]+)  # Match one of more digit and close capture group
'        # Match the closing single quote

What about this?

onclick.match(/show_clipping\.php\?CLIP_id=\d+/)
["show_clipping.php?CLIP_id=575"]

(From the tags of your question I assume you're using JavaScript)

show_clipping.php\?CLIP_id=(\d+)

\d matches a digit, and + means 1 or more of them.

How about:

/(show_clipping.php\?CLIP_id=[1-9]\d*)/
