Take the following code:

<?php
$xml = '<?xml version="1.0"?><foo><bar></foo>';
$doc = @xmldoc($xml);
if (!$doc) {
        echo "invalid xml\n";
}
?>

If you run it from the shell, the parser spits a bunch of messages out to STDOUT.  It would be nice if these could be repressed and/or captured easily by the script somehow (in $php_err_msg or something).
