I am trying to do a search through some data, more specifically HTML,
to extract data from it. So for example I may have:
<b>Title:</b> <em>This is a title</em>
<b>Name:</b> <em>Fred</em>
I wish to grab the data "This is a title" and "Fred" against their
corresponding headings in an array (e.g. $array[title] = "This is a
title") .... but the key doesn't matter, that need not come from the
regexp but I can do manually.
The question is - how do I do this in one pass? Do I just use use
nested OR's in my regexp? The problem with this though, is once a match
is made, how does PHP then tell me what it corresponds to if it's an
OR? (it just returns the match surely?)
Actually i'm not even too sure how to go about doing this... do I need
backreferencing etc...? I've read the php.net pages but couldn't
entirely make sense of the various preg functions.
Thanks a bunch!
Terence
