I have a situation like
<td><a href="http://www.bar.com/">http://www.bar.com</a>http://www.other.com/</td>
And I have a regular expression set up to capture urls
But is there any reliable way to link link up the other URL? I was thinking I could use .innerHTML, but that is going to catch links that are already linked up. And if I just use textContent, find the url and replace it, how can I set this back to the td without wiping out the bar link? I am not looking for a solution to this specific problem, but a general solution for where an element may have a url but also have other element children (that might also contain url text or in their html/hrefs).
I could go node by node, but this is not reliable – the text could be broken up into multiple nodes, or?
I’d like to auto-link up discovered URLs that aren’t already linked, but I can’t think of a reliable way to do this. Does anyone have a solution to this problem?
