thanks

<a\s+([^>]*)href="(https?:\/\/([^"]*))"\s+([^>]*)title="xyz"(.*?)>(.*?)<\/a> you can get the url by partial match $2, you can try it here

To be honest, I would use an HTML parsing library to just get the contents of the href attribute.

/href="(.*?)(?=".*?title)/

you will have to trim the href=" from the beginning of the match

/abc(?=xyz)/ positive lookahead -> matches abc if abc is followed by xyz
