Q:

Javascript RegEx - I want to match a pattern other than the first occurance

I want to convert this:
.className#lets.par.ty
To this:
.className[id="lets"][class="par"][class="ty"]
I don't want to alter the first instance of the "." 
Here is what I came up with but I know it is absolutely NOT ideal:
cssOutput[i] = cssOutput[i]
.replace (/^#/,'?') //  convert all start ids to ?     
.replace (/#([^\.#]+)/g,'[id="$1"]') // insert [id=""]
.replace (/\?/g,'#') // convert all start ?  back to ids
.replace (/^\./,'?') //  convert all start classes to ?    
.replace (/\.([^\.#]+)/g,'[class="$1"]') // insert [class=""]
.replace (/\?/g,'.') //  convert all start ?  back to classes

Can anyone help?  

A:

Try:
var s = ".className#lets.par.ty";
s = s.replace(/\.(\w+)#(\w+)\.(\w+)\.(\w+)/, '.$1[id="$2"][class="$3"][class="$4"]');

EDIT
To skip the first first character of the input, simply do something like this:
var tests = ['.className1', '#className2', '.className.class1#class2#class3'];

for(var index in tests) {

  var t = tests[index];

  t = t.charAt(0) + t.substring(1). 
      replace(/\.(\w+)/g, '[class="$1"]'). 
      replace(/#(\w+)/g,  '[id="$1"]');

  print(t);
}

which produces:
.className1
#className2
.className[class="class1"][id="class2"][id="class3"]
