Title Test Details Pattern Title
Expression
&lt;a\s*href=(.*?)[\s|&gt;]
Description
Retrieves all anchor links in a html document, useful for spidering. You will need to do a replace of &quot; 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 &quot;,' or nothing at all (&quot; and ' is easy enough, but what happens if the link starts with &quot;, 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.
Matches
&lt;a href=&quot;http://www.blah.com&quot;&gt; | &lt;a href='../blah.html' target=&quot;_top&quot;&a
Non-Matches
&lt;a href = http://www.idiothtmlprogrammers.com &gt;
