The reg > exp is matching the entire $filedata rather than stopping at the first ">" > after "<body". How do I get it to stop at the first ">" after > "<body"? It's being greedy. You are telling it to match anything and everything, and then end with a >. Try something like this, instead. eregi_replace("<body([^<]*)>" That'll match anything after body and between the closing > tag, but won't match the < of the next tag. Don't know if I explained that very well, but have a go at it. :) ---John Holmes...
