Question

using regex to get a string between 2 strings and can’t figure out how to ignore the start and end strings.

"imgurl=(.*?)&amp"  

this expression working fine except i need to ignore imgurl= and &amp?

by matching the following string:

imgurl=mytext&amp

the result i got is like

imgurl=mytext&amp

it has to be

mytext

You haven’t specified the language, but be sure you are checking the appropriate match group…

>>> msg = "imgurl=mytext&amp"
>>> import re
>>> foo = re.search("imgurl=(.*?)&amp", msg)
>>> foo.group(1)
'mytext'
>>> foo.group(0)
'imgurl=mytext&amp'

Obviously, group 1 is what you’re looking for…

EDIT

For vb.net code..

Dim regex As Regex = New Regex("imgurl=(.*?)&amp")
Dim match As Match = regex.Match("imgurl=mytext&amp")

Assuming you get the match, you need the value from match.Groups(1).Value
