Replacing text in a string

[idesdema]

Hello. I am pulling in a friend's rss feed and we are trying to figure out how to make images display correctly. Here is a sample chunk that I pull in:

I am posting a forum image here Image: http://mysite/test.jpg

How would I be able to make the "Image: http://mysite/test.jpg" part if that post change to "<img src=" http://mysite/test.jpg">"

I tried REReplace but couldn't get it to replace correctly. Can someone please help me out?

<cfset str = "test test test Image: http://mysite/test.jpg test test test" />
<cfset str = rereplaceNoCase(str, 'Image: (https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)', '<img src="\1" />', 'all') />

<cfoutput>#htmlEditFormat(str)#</cfoutput>

That is awesome. If you want to, or have time, I'd love to understand how that works.

well, i'm no regex guru... that pattern to match a URL was found via google 🙂

the rest of it is pretty straightforward. find any instance of "Image: " followed by the URL pattern. The URL pattern is enclosed in parentheses which means we can reference it later as \1. so you now have that URL in what's essentially a variable... pop that variable into the <img src= /> and that's all she wrote.
