What version of CF?
I might be able to come up with a better way using lookahead...

: Subject: highlight UDF
:
:
: Hey folks,
: I suck at regex, which is why I helped sponsor that little tool that Mike
: found, but I'm still having trouble figuring this out. And, since it was
: originally written by Raymond, I thought I'd throw this out here.
:
: There's this UDF, which we already modified once to use a span
: class instead
: of just a simple background color, that highlights a search term. But, if
: the search term happens to contain the letters inside the span, like say,
: for instance, if someone searchs for "pan", the UDF overwrites the span
: text. I'm sure there's a way to write the regex to look for the
: search term
: except when it's in this "<span class="hlt">anythinghere</span>"
: but I don't
: know how to do it. Here's the UDF:
: <cfscript>
: /**
: * Applies a simple highlight to a word in a string.
: *
: * @param string The string to format.
: * @param word The word to highlight.
: * @param front This is the HTML that will be placed in front of the
: highlighted match. It defaults to <span style=
: * @param back This is the HTML that will be placed at the end of the
: highlighted match. Defaults to </span>
: * @param matchCase If true, the highlight will only match when the case
: is the same. Defaults to false.
: * @author Raymond Camden ([EMAIL PROTECTED])
: * @version 1, July 30, 2001
: */
: function highLight(str, wordList) {
:
:
: /**
: * Modification by Kevin Graeme
: * Added a class descriptor called "hlt" to the global css styles,
: * and changed the span style from a direct style to a called class.
: * This resolves a Netscape 4.x CSS implementation problem.
: */
: /* var front = "<span style=""background-color: yellow;"">"; */
: var front = "<span class=""hlt"">";
: var back = "</span>";
: var matchCase = false;
:
: //check for empty word list, this is the base condition for the recursion
: if(ListLen(wordList) Lt 1)
: return str;
: else
: word = ListFirst(wordList);
:
: if(ArrayLen(arguments) GTE 3) front = arguments[3];
: if(ArrayLen(arguments) GTE 4) back = arguments[4];
: if(ArrayLen(arguments) GTE 5) matchCase = arguments[5];
:
:
: if(Not matchCase)
: CurTxt = REReplaceNoCase(str,"(#word#)","#front#\1#back#","ALL");
: else
: CurTxt = REReplace(str,"(#word#)","#front#\1#back#","ALL");
:
: return Highlight(CurTxt, ListRest(wordList), front, back, matchCase);
:
: }

: </cfscript>
