Get href labels using RegEx Tutorial

ColdFusion Tutorial #24

Ever wondered how you 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:

demo.cfm

I create a string with a few links in it on lines 1-7.

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 this is done on line 9.

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 on lines 12-15.

Run the demo to see the dump output.
