Thinking out loud, you could create a custom translator (subclass of CharSequenceTranslator). If the letter was an &, you would look ahead to determine if it was a valid escaped character. If so you would write them out and return the size of what you wrote.

Then you would create an AggregateTranslator around your custom translator and StringEscapeUtils.ESCAPE_XML11.
