Regex problem. - i3urn - Apr 12, 2017

Trying to create a regex that grabs the conditions and statements from if statements.

Currently I have this.

Code 
if\((.*)\)[\r\n]*{[\r\n]*(.*)[\r\n]*}

But it only matches single line statements such as

Code 
if(value >= 5)

{

DoSomething();

}

When I need it to match multi-line statements such as

Code 
if(value >= 5)

{

DoSomething();

DoSomethingElse();

}

Been testing here any help would be much appreciated :)

This should work

Code 
if\((.*)\)\n{([\r\n]*(.*)[\r\n])*}

Idk why you have [\r\n]* instead of just \n after if() pattern.

Cheers, that worked perfectly (with a little bit of editing to make it non-greedy)

Code 
if\((.*)\)[\r\n]*{([\r\n]*(.*)[\r\n])*?}

Looks good. 🤝

Don't lexers omit whitespace and line breaks when parsing?
