Here's what I settled on. Thanks for all the help! The CharSequences
sped things up the most, and using an Entry set helped also. I'm now
just a tiny bit less of a newbie 8^)

    static String unescapeString(String inputString) {
        Set<Map.Entry<CharSequence, CharSequence>> set =
entitiesHashMap.entrySet();

        for (Map.Entry<CharSequence, CharSequence> me : set) {
            inputString = inputString.replace(me.getKey(), me.getValue
());
        }

        return inputString;
     }

These are just string replacements I'm trying to do, not regular
expressions. Here's the WRONG way to do it, but hopefully it tells
you what it is I'm trying to do...

    static String unescapeString(String string) {
        Iterator i = entitiesHashMap.keySet().iterator();
        for (String key : entitiesHashMap.keySet()) {
            string = string.replaceAll(key, (String)
entitiesHashMap.get(key));
        }

        return string;
    }

entitiesHashmap is a HashMap with literally hundreds of entries.

Any help would be greatly appreciated.
