Regex PHP, Match all links with specific text

Question

I am looking for a regular expression in PHP which would match the anchor with a specific text on it. E.g I would like to get anchors with text mylink like:

Answer 1

/]*>([^<]*mylink[^<]*)<\/a>/

it's a bit simplistic, as it will break if tags are inside the link (xyz mylink aaa), but it should work.
