This way it finds the first closing parenthesis it comes across and stops matching, rather than the last. and for the replace statement, you shouldn't need to escape the characters, so IsDefined("$1") should work nicely for you Hope this helps, and thanks for reading. Hi Kathy,
I think I see what the error is…it looks like you forgot the + after the capturing element, so
ParameterExists\(((.)+)\)
However, using that “greedy” capture, it will keep going until it finds the last parenthesis (I wasn’t sure, so I ran a quick test :) )
The way I usually handle this is to do something like this:
ParameterExists\(([^\)]+)\)
This says find ParameterExists( then match all “non-closing parenthesis characters”, then match ). This way it finds the first closing parenthesis it comes across and stops matching, rather than the last.

and for the replace statement, you shouldn’t need to escape the characters, so
IsDefined(“$1″)
should work nicely for you

Hope this helps, and thanks for reading.

I wonder if you could help with a problem I'm having: I'm trying to replace ParameterExists(someVar) with IsDefined("someVar") someVar can contain any characters I thought the Find expression would be ParameterExists\((.)\) and the Replace expression would be IsDefined(\"$1\") However the Find expression is not working. Can you see my error? Thanks, Kathy Hi Gareth,

Thanks for the useful articles on regular expressions.

I wonder if you could help with a problem I’m having:

I’m trying to replace ParameterExists(someVar) with IsDefined(“someVar”)
someVar can contain any characters

I thought the Find expression would be ParameterExists\((.)\) and the Replace expression would be IsDefined(\”$1\”)

However the Find expression is not working.

Can you see my error?

Thanks,
Kathy
