How can I get the string before the character "|" using regular expressions?
For example, I have "data1|data2" and I want to return "data1".

1What language? What have you tried? – chris85 May 18 '17 at 15:59

You have `data1|data2`, I have `|data1|data2` and we both want `data1` because we see that _data1_ is what is needed. So, what does the pipe have to do with it ?? – May 18 '17 at 16:22

You want this regex: ^.+?(?=\|)
^beginning of line.+?one or more characters, as few as possible(?=)forward look ahead assertion; make sure you can see the enclosed pattern\|a literal|character

2Why not simply `^[^|]*` ? Using a lookahead in this context seems overkill. – Aaron May 18 '17 at 16:01

@Aaron Good point. Post your own answer and I'll upvote it as also correct. – Phrogz May 18 '17 at 16:01

1I'd rather find a good duplicate than post an answer, there's no way this isn't already answered in other questions. – Aaron May 18 '17 at 16:04
