With longish text nodes, this approach could result in some pretty deep recursion couldn't it? I once managed to crash Saxon using exactly this approach (although I can't duplicate that result now). > If you work by cycling through the replacements, surely > > <foo:char>$</foo:char> > and > <foo:replace>$\mathbb{P}$</foo:replace> > > will fight? the $ in the second fragment might end up escaped This always happens with languages with special characters (even XML, when doing some dodgy escaping to produce elements). So far I've always managed to find an order of character replacement that works. If not, you can replace special characters with some really unlikely string, do some more replacement, and then replace the unlikely string with the desired result as the final step. -- Warren Hedley Department of Engineering Science Auckland University New Zealand XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
