Cleaning Up Verity Results (Coldfusion)
By Raymond Camden
Christian Ready pinged me a few days ago about an interesting problem he was having at one of his web sites.
His search (Verity-based on CFMX7) was returning HTML. The HTML was escaped so the user literally saw stuff like this in the results:
The "non greedy" part means to match the smallest possible match possible. Without this, the regex would remove the html tag and everything inside of it! We just want to remove the tags themselves.
This worked - but then exposed another problem. Verity was returning text with incomplete HTML tags. As an example, consider this text block:
Notice the incomplete HTML tag at the beginning and end of the string.
Luckily regex provides us with a simple way to look for patterns at either the beginning or end of a string. Consider these two lines:
Most likely this could be done in one regex instead.
