Getting All The Link Labels From A String In ColdFusion
 By
Raymond Camden
A reader asked me how they could use regex to find all the link labels in a string.
Not the links - but the label for the link. It is relatively easy to grab all the matches for a regex in ColdFusion 8, consider the following code block:
I create a string with a few links in it. I then use the new reMatch function to grab all the matches. My regex says - find all HTML links. It isn't exactly perfect, it won't match a closing A tag that has an extra space in it, but you get the picture. This results in a match of all the links:
But you will notice that the HTML links are still there. How can we get rid of them? I simply looped over the array and did a second pass:
This gives you the following output:
p.s. Running on ColdFusion 7? Try the reFindAll UDF as a replacement to reMatch.
