Given an HTML string like:
<span class="findme" id="31313131313">The Goods</span>
What kind of REGEX in Coldfusion would return just (if it's even possible?): 31313131313
Thanks!

A:
It is not a good idea to parse html using regex in general. Use an html parser instead.
That said, the following regex will give you the id from the given string.
<span[^>]*id="(\d+)"
The first group of the match, $1, will contain 31313131313.
It assumes a numeric id. For alphanumeric ones, replace \d with [0-9a-zA-Z]. You can use \w if _ is fine too.

@Amarghosh thxs, it will always be numeric. I just tried this but it returned the entire string, no change. Any ideas why?

Here is the full line: <cfset uniqueID = rereplace(results[i], '<span[^>]*id="(\d+)"', '\3')>

Change `\3` to `\1` We've just one capturing group.

I don't know CF, but try this: `<cfset uniqueID = rereplace(results[i], '.*<span[^>]*id="(\d+)".*', '\1')>`

A:
Try, <span[^>]+?id="([^"]+)".*
According to your comment in Amarghosh answer, that would be
<cfset uniqueID = rereplace(results[i],'<span[^>]+?id="([^"]+)".*',"\1")>
