Ben,
I can see what you've got (I think) and it makes sense, but for some
reason, it's not working. I'm grabbing the html from www.google.com and
running it on it and this is what I've got in my code:
#refindnocase('<img.*?src="(.*?)".*?>',cfhttp.fileContent,0,true)#
I'm using <cfdump to display that info and what I see are 2 arrays (len
and pos) and both have values of 1 and 0. I thought that if the first
value was 1, the second value would be the position of the occurrence of
the search string. I know google has an image, and I'm displaying the
cfhttp.filecontent in a textarea above so that I can ensure the results
are coming back as expected. Any ideas? Am I doing something wrong?

Subject: Re: regex help for grabbing values of html tag attributes
Well, I see a couple of problems with what you're using. First, you've
not got a closing " on the attribute. Second, you've wrapped a regex
that contains a " in ""'s, which will error out if you don't escape the
inner "'s. You can wrap it with single quotes to fix that. Also, the
last * boggles me. I don't know why it's there.
Or, try this:
'<#tag#.*?#att#="(.*?)".*?>'
where (should be obvious) tag and att are defined as the tag and
attribute you want. Please note that if you define them as "span" and
"class" and you have this:
<span>stuff in between<span class="bob"> the "whole tag" match will
return both span tags and the stuff in between. The attribute match
will return bob. So, if this might be the case, lemme know and we'll
tweak the regex.
Not tested, your miles may vary, trix are for kids, etc.
