REX Question

[gerry.odea]

I know that with the rex expression below I can get everything after the "?". But how do I write the rex to get everything before the "?". I've tried everything and can't seem to figure it. Please let me know. Thanks.

<rex "[^?]+>>=" $url><$url=$ret>

">>=[^?]+"

Or <urlutil split> or <split "\?">.

Thank you Mark!
