Steve,
Yep perfecto! Here's what I ended up with. Returns a struct of unique keys
with each key containing a count of the number of occurrences.
Run it on itself and you get
struct
cfargument
2
cfdump
1
cfelse
1
cffile
1
cffunction
1
cfif
3
cfloop
1
cfreturn
1
cfset
10
Thanks for your help, since you are so good at RegEX's I wonder if you might
be interested in attempting to fix the color coding, which is 90% regex's.
<cffile action="read" file="#expandPath('test.cfm')#" variable="cf" />
<cfdump var="#getTag(cf)#" />
<!--- Get a unique list of tags from coldfusion code --->
<cffunction name="getTag" access="public" returntype="struct">
<cfargument name="code" type="string" required="true" />
<cfargument name="sort" type="boolean" default="true" />
<cfset local = {} />
<cfset local.result = {} />
<cfset local.expression = "<(cf[^ >]*)" />
<cfif reFindNoCase(local.expression, arguments.code)>
<cfset local.start = reFindNoCase(local.expression, arguments.code)
/>
<cfloop condition="#reFindNoCase(local.expression, arguments.code,
local.start)#">
<cfset local.tag = reFindNoCase(local.expression,
arguments.code, local.start, true) />
<cfset local.key = mid(arguments.code, local.tag.pos[2],
local.tag.len[2]) />
<cfif NOT structKeyExists(local.result, local.key)>
<cfset local.result[local.key] = 1 />
<cfelse>
<cfset local.result[local.key] ++ />
</cfif>
<cfset local.start = local.tag.pos[1] + local.tag.len[1] />
</cfloop>
</cfif>
<cfif arguments.sort>
<cfset structSort(local.result, 'text') />
</cfif>
<cfreturn local.result />
</cffunction>

Charlie,
I have already got a Color Coder, which I hacked from the BlogCFC one, as
for many alternatives, I couldn't find anything decent.
I actually want it for something else, but if you have a good color coder or
a link to such I would be interested in having a look at it.
My one is still a bit buggy.
Regards
Dale Fraser

Dale, might you be doing this to create a tool to do color coding in your
learncf code examples? If so, just note that there are many existing
alternatives for that. If you're doing it for some other reason, no worries.
Just thought I'd ask if that might be the real root of the question.

I struggle with RegEx's
Anyone know if this is even possible.
I want to pull out a unique list of coldfusion tags in a given source string
I assume I can match
<cf*[space]
Can the regex do the unique bit, or do I need to loop through and build a
structure.
