How do I ignore empty lines in this regex?

Question

I am trying to figure out how I ignore empty lines with spaces but no content. I have the following

^(\s*)SetEnv

Which matches what I am looking for fine, but it also matches empty lines with just spaces

So

SetEnv blah // matches
 // also matches
// doesn't match

You should probably replace * with + (means one or more) — robertrosman

Assuming that you use the m modifier, you can use:

^(\h*)SetEnv

or

(?m)^(\h*)SetEnv

\h only matches horizontal white-spaces.

Never noticed the \h shorthand char class before. Thanks! +1
