How to write regex to handle multiple spaces?

Question

I need a regex that will get the name of a label. The labels look like this:

lbl LabelName

The regex will need to return LabelName. I manged to make this:

(?<=\slbl\s).+?(?=\s)

This works fine as long there is only one character between "lbl" and "LabelName". If I add two spaces or more spaces then it will return the extra spaces.

I tried (?<=\slbl\s+).+?(?=\s) but it doesn't work either.

I solved it using a without using a regex. I used a lexer that I created a while back. — Aaron de Windt

Your comment could be added as an answer. Can you post it? (And the code for the lexer if it's short enough and you own it?) — Bill the Lizard

Does the following regular expression work for you?

lbl\s+([^\s]+)

Use this: ^lbl\s+(\S+)$. In 1st group you obtain LabelName.

You can keep the extra spaces with the 'lbl' part and still capture LabelName with something like this:

^lbl\s+(.*)
