Hey,
Thanks for the feedback and the sample code.
I'm going to look over this in more detail today.
Thanks again everyone!

I have to say, the error reporting for the XML and XSLT functions are
terrible.
Here's how I load XML. Requres track_errors to be on. Sorry about the
line wrapping.
$xml_string = '';
$schema_file = '';
if (($dom = @DOMDocument::loadXML($xml_string)) == false) {
$error = 'Malformed XML: ' . $php_errormsg;
} elseif ((@$dom->schemaValidate($schema_file)) == false) {
$error = 'XML violates schema ' . $schema_file . ': '
. format_schemavalidate_error($php_errormsg);
} else {
if (($sxml = @simplexml_import_dom($dom)) === false) {
$error = 'Malformed XML (SimpleXML): ' . $php_errormsg;
}
}
if (!empty($error)) {
// process...
}
/**
* Boils down XML schema validation error messages into something
* humans can easily comprehend
*
* @param string $error the $php_errormsg produced by DOM
* schemaValidate()
*
* @return string
*/
function format_schemavalidate_error($error) {
$error = preg_replace('/\s+/', ' ', $error);
if (preg_match("/The element: '([^']+)'/", $error, $match)) {
$error = $match[1] . ' has invalid value . ';
} elseif (preg_match("/Element '([^']+)', attribute '([^']+)'/",
$error, $match)) {
$error = $match[2] . ' attribute of ' . $match[1] . ' has invalid
value . ';
} elseif (preg_match("/Element '([^']+)': The attribute '([^']+)' is
required/", $error, $match)) {
$error = $match[2] . ' attribute of ' . $match[1] . ' is missing
. ';
} elseif (preg_match("/is not a valid value of the atomic type
'({.*})?([^']+)'/", $error, $match)) {
$error = $match[2] . ' has invalid value . ';
} elseif (preg_match('/Expecting: ([^.]+)/', $error, $match)) {
$error = $match[1] . ' is missing . ';
} elseif (preg_match('/(Expected is|Expected is one of) \(
({.*})?([^.]+) \)/', $error, $match)) {
$error = $match[3] . ' is missing . ';
}
return $error;
}
Enjoy,
