Regex Nightmare

[webmigit]

<!-- B,I,U Markup -->
<CFLOOP list=&quot;B,I,U,STRONG,EM&quot; index=&quot;m&quot;>
 <CFSET sig=REReplaceNoCase(sig,&quot;[#chr(91)#](#M#)[#chr(93)#]([^(#chr(91)#b#chr(93)#|#chr(91)#/b#chr(93)#)]*)[#chr(91)#][/](#M#)[#chr(93)#]*&quot;,&quot;<\1>\2</\1>&quot;,&quot;ALL&quot;)>
</CFLOOP>

I'm trying to make the above turn:

[b]test[/b] this [b]now[/b]

into test this now but all its doing is turning it into: test

[/b] this [b]

now Did I help?
Vote!

The first thing I'm going to point out is that you can use

\[

instead of

#Chr(91)#

to represent a literal opening bracket. I find the former to be much easier to read, and that's how I've written the example below.

My suggestion would be to stop trying to find both start and end tags with separate parts of a single expression. The following code finds either a start or end tag of the specified type, and turns it into its HTML counterpart:

  #ReReplace(sig,&quot;\[(/?)(b|i|strong|u|em)\]&quot;,&quot;<\1\2>&quot;,&quot;ALL&quot;)#

I used the following string to test it out:

  test [b]this [[u]not[/u] [i]that[/i]!][/b] thing [strong]now[/strong], and [em]I mean it[/em]!
