<!---Inspiration (and some code [all the regex]) from Ben Nadel http://www.bennadel.com/index.cfm?dax=blog:584.view--->
<!---Create the local scope--->
<cfset var local = {}>
<!---This struct will hold all of the rules--->
<cfset LOCAL.cssRules = {}>
<!---
Remove all line breaks. We are going to be doing some
regular expressions and stripping out line breaks will
make things slightly less complicated.
--->
<cfset LOCAL.strCSSData = reReplace(arguments.css_data,"[\r\n]+", " ","all") />
<!---
Strip out the CSS comments. These hold no value for us
when we are getting the classes.
--->
<cfset LOCAL.strCSSData = reReplace(LOCAL.strCSSData,"/\*.*?\*/", " ", "all" ) />
<!--- Create an array to hold all of the class names. --->
<cfset LOCAL.arrClasses = ArrayNew( 1 ) />
<!---
Loop over the rules. Remember, each rule is now sepparated
by a pipe (when we stripped out the {..} stuff), so we
can loop over the rules as a pipe-delimited list.
--->
<cfloop
index="LOCAL.strRule"
list="#LOCAL.strCSSData#"
delimiters="}">
<!---
Check to see if we still have a length (name(s)) of
CSS classes.
--->
<cfif Len( trim(LOCAL.strRule) )>
<!---Add the item to the array--->
<cfset arrayAppend(LOCAL.arrClasses,LOCAL.strRule) />
</cfif>
</cfloop>
<cfloop array="#LOCAL.arrClasses#" index="LOCAL.each_class">
<cfset LOCAL.cssRules[trim(listFirst(LOCAL.each_class,"{"))] = {}>
<cfloop list="#trim(listLast(LOCAL.each_class,"{"))#" delimiters=";" index="LOCAL.each_rule">
<cfset LOCAL.cssRules[trim(listFirst(LOCAL.each_class,"{"))][trim(listFirst(LOCAL.each_rule,":"))] = trim(listLast(LOCAL.each_rule,":"))>
</cfloop>
</cfloop>
<cfreturn LOCAL.cssRules>
