Converting a php regex to javascript

Question

how to convert the following php regex to javascript regex?

php regex:- (?s)(?<=<a).*?(?=<\/a>)

Is this supposed to extract the href="something" part of a link? — Purag

It is used to extract all between <a> and </a> in php. It is perfectly answered below for JavaScript :) — user2726225

It's not possible to use the exact same pattern in javascript, because lookbehinds aren't supported.

The best I could do is

<a([^]*?)(?=<\/a>)

It should match the same text as the php regex, but captures the text in the first capture group instead.

[^]*? <-- I think this is a typo? Should probably say something like [^<]*? but then it would fail on <a href="#yo"><b>click me</b></a>. Stick with .*? or, you know, don't use regexes to parse HTML to begin with ;)

Hi Rawing... Exactly what I wanted and works perfectly for my scenario :) Unfortunately I do not have 15 reputation to vote up your answer :(

@funkwurm: [^] is intended. It's perfectly valid regex meaning "match absolutely any character, even newline".
