Regular expression help needed

[Prashant Langade]

Hi

I dont have much knowledge of Regular expressions.

My requirement is to match the string starting and ending with underscore i.e "_"

that means

if i have strings as
1> _abc_
2>_abc_av
3>ab_abc_
4>_pqr_

then only _abc_ and _pqr should be able to match the pattern.
Can any one please help me?

Something like "^_.*_$" should do the trick.

"^_.*_$" will also match __ (two underscores, with no string). If you don't want that then just replace the *(which means zero or more) with +(which means at least 1 or more). "^_.+_$"
