> So you suggest to place the & translation last. That would be a solution for this problem. My previous comments on the "minimalistic" approach of the implementation suggest a different approach: scan the source string once and replace html entities as you find them (with a look up table for example). This would scale much better when implementing iso-8859-1 or '&#entity-number;' unescaping . Ludo

Input to EscapeHTML: '<' Output: '&lt;' : Correct UnescapeHTML: input '&lt;' Output '<' Wrong. This is because you replace '&' with '&' resulting in '<' which is translated to '< ' in the next line. So you suggest to place the & translation last.

Test against: "&lt;" I'm not sure what you mean here. If you have already html entities you should not escape them. If you do not have html entities you should escape them. The Escaping and unescaping works well, I already tested them before I sent them. Right unescape "<", your code "<". -- Best regards, José Ido _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
