I would rather not do that as "if" statement here tends to hides the potential error. Better, in my opinion, is to use directly: par.appendChild(text); "par" is always defined, but text doesn't have to be or can be passed as a non-string type. In that case executing par.appendChild(text); will throw DOM exception and the error can be spotted easily. [...] -- Cezary Tomczyk http://www.ctomczyk.pl/
