[DOM] Dom\XMLDocument::schemaValidate fails to resolve xs:QName with prefix from imported schema (works in DOMDocument) #22219
Description
Description
The following code:
<?php
$xmlString = file_get_contents(__DIR__ . '/test.wsdl');
echo "=== Testing with new Dom\\XMLDocument (PHP 8.4+) ===\n\n";
testValidation("Direct custom.xsd", $xmlString, __DIR__ . '/custom.xsd', true);
echo "\n=== Testing with old DOMDocument (for comparison) ===\n\n";
testValidation("Direct custom.xsd", $xmlString, __DIR__ . '/custom.xsd', false);
function testValidation(string $name, string $xmlString, string $xsdPath, bool $useNewDom): void
{
libxml_use_internal_errors(true);
libxml_clear_errors();
if ($useNewDom) {
$doc = Dom\XMLDocument::createFromString($xmlString, LIBXML_NSCLEAN);
$valid = $doc->schemaValidate($xsdPath);
} else {
$doc = new DOMDocument();
$doc->loadXML($xmlString, LIBXML_NSCLEAN);
$valid = $doc->schemaValidate($xsdPath);
}
echo "[$name] " . ($useNewDom ? "Dom\\XMLDocument" : "DOMDocument") . " → ";
if ($valid) {
echo "✓ VALID\n";
} else {
echo "✗ INVALID\n";
foreach (libxml_get_errors() as $error) {
echo " Line {$error->line}: {$error->message}\n";
}
libxml_clear_errors();
}
}Resulted in this output:
=== Testing with new Dom\XMLDocument (PHP 8.4+) ===
[Direct custom.xsd] Dom\XMLDocument → ✗ INVALID
Line 9: Element '{http://schemas.xmlsoap.org/wsdl/}part', attribute 'element': The QName value 'ssp:CustomElement' has no corresponding namespace declaration in scope.
Line 9: Element '{http://schemas.xmlsoap.org/wsdl/}part', attribute 'element': 'ssp:CustomElement' is not a valid value of the atomic type 'xs:QName'.
=== Testing with old DOMDocument (for comparison) ===
[Direct custom.xsd] DOMDocument → ✓ VALID
But I expected this output instead:
=== Testing with new Dom\XMLDocument (PHP 8.4+) ===
[Direct custom.xsd] Dom\XMLDocument → ✓ VALID
=== Testing with old DOMDocument (for comparison) ===
[Direct custom.xsd] DOMDocument → ✓ VALID
