RegEx is not necessarily the ideal tool for this - try a DOM Parser.
If you've got consistent/controlled input you can use regex, and here's a Java
one that will work in most situations:
<a[^>]+?\shref\s*+=\s*+["']([^"']++)["'][^>]++>(.*?)</a>
To use that with CFML, you can use my jre-utils CFC (which is GPL Free
Software, rather than a $15 per server tag).
Here's an example, along with a commented version of the above regex:
<cfset jre = createObject('component','jre-utils').init()/>
<cfsavecontent variable="reFindHyperlinks">(?xis)
# Flags (above):
# x = enable regex comment-mode;
# i = make case-insensitive;
# s = allow . to match newlines;
# Main Regex:
<a[^>]+? # start of tag, lazily match at least one non->
\bhref\s*+=\s*+ # match href attribute, word boundary at start, allow
whitespace around =
["']([^"']++)["'] # match value of href, possessive capture contents
between the quotes (note: doesn't support inverted embedded quotes)
[^>]++> # rest of tag, possessively matching non-> then >
(.*?) # lazily capture any tag contents
</a> # end of tag
</cfsavecontent>
<cfset Results = jre.matchGroups( reFindHyperlinks , cfhttp.FileContent ) />
<cfdump var=#Results# />
That will set Results to an array of matches, each one containing a struct with
the matched string, plus an array of the groups.
All make sense?
