How 'bout doing it in two steps: First flag all the text strings that you
want to apply the style to by surrounding them with some rarely encountered
chars...
REReplaceNoCase(threads.message, "(#query#)","~~\1~~","ALL");
then go through and apply the styles to all the strings...
REReplaceNoCase(threads.message, "~~([^~]*)~~","<SPAN
CLASS='highlight'>\1</SPAN>", "ALL");
Note: To insure that a ~ appearing in the text is handled correctly, just
replace all ~ with "some unique string !@$$%@" before doing the above, and
then replacing all occurrences of "some unique string !@$$%@" with ~ after
you're done.
Hope that helps.

Subject: searching arrays with regular expressions
| Hello,
|
| I am having the search function of a CF template highlight words that a
user
| entered in their query. For example, if someone searches for "test" in
the
| query box, it would then go through and replace the word "test" with a
span
| tag with class "highlight" in order to highlight it. The following code
is
| how I did it:
|
| REReplaceNoCase(threads.message, "(#query#)","<SPAN
| CLASS='highlight'>1</SPAN>", "ALL");
|
| After implementing this feature, I made it so that the CF template takes
all
| the words in the string "query", and makes and array out of it called
| "keywords", with each element of the array being a different word from the
| original string "query." To make it do that the search/highlighting
| function worked with the new code, I did a CFLOOP of the REReplaceNoCase
| function, each time making the word to change a different element in the
| keyword array. The only problem was, if someone searched for something
with
| the words "span" or "highlight" or any part of those words, the second
time
| the loop went around it would replace the things it itself added into the
| message, thus making it so that the highlighting of the first word in the
| keywords array wouldn't work, and would even display partial HTML around
it.
| Is there a way to make the REReplaceNoCase function search through a
message
| and replace any word that appears in a certain array rather than replacing
a
| single word?
|
| Thanks,
| Brent
