Title	Test Details Pattern Title
Expression	<a\s*href=(.*?)[\s|>]
Description	Retrieves all anchor links in a html document, useful for spidering. You will need to do a replace of " and ' after the regular expression, as the expression gets all links. As far as I know there is no way, even with \1 groupings, of getting a condition on whether the link contains a ",' or nothing at all (" and ' is easy enough, but what happens if the link starts with ", and has a javascript function call with a string in it). If there is, it's probably quicker to do it like this and do a string replace anyway.
