Your expression probably didn't match anything. Try: preg_match_all("|<test>(.*)</test>|U", ... However I believe this is greedy and will match /everything/ from the first <test> tag to the last </test> tag. I'll leave it as an exercise for you to modify it so it's non-greedy. Hint, the examples in the manual (I think there was one about stripping HTML tags) gives a good starting point. Also for debugging, a better way to display the contents of $out is: print_r($out); -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* A computer lets you make more mistakes faster than any other invention, with the possible exceptions of handguns and Tequilla. -- Mitch Ratcliffe */
