That's a good suggestion, and it led me to look into regexp-opt for the first time. But how do I get it to capture just the variant part of the matched strings in "\\( ... \\)" i.e. excluding any common prefix or suffix? E.g. (regexp-opt '("»" "’")) => "&#\\(?:\\(?:18\\|821\\)7;\\)" (regexp-opt '("»" "’") t) => "\\(&#\\(?:\\(?:18\\|821\\)7;\\)\\)" But what I'd like it to return is "&#\\(\\(?:18\\|821\\)7;\\)" so that (match-string 1) would return just "187" or "8217". -- Kevin Rodgers Denver, Colorado, USA
