Regression: DOMElement::$prefix / $namespaceURI null on createElementNS nodes (ext/dom/node.c) #15381

Category

stdlib · php-src-strict · DOM namespace node properties

Problem

DOMElement nodes created with createElementNS($namespace, $qualifiedName) must expose live prefix and namespaceURI properties. Zend returns ex and http://example.com/ns for createElementNS('http://example.com/ns', 'ex:a'). This compiler leaves both properties null.

Verified 2026-07-03 on master.

php-src reference

• php/php-src ext/dom/node.c — dom_node_namespace_uri_read, dom_node_prefix_read
• php/php-src ext/dom/php_dom.c — property registration on DOMNode/DOMElement

PHP implementation target

• ext/dom/VmDom.php + DomNodeState — persist namespace URI + prefix when creating NS-qualified elements; expose via DOM object property reads (same path as nodeName / tagName)
• PHP-in-PHP first in ext/dom/; shrink any duplicate C if present

Repro (verified 2026-07-03)

./script/docker-exec.sh -- bash -lc 'php test/repro/maintainer_gap_dom_element_ns_properties.php'      # Zend: ok
./script/docker-exec.sh -- bash -lc 'php bin/vm.php test/repro/maintainer_gap_dom_element_ns_properties.php'  # fail exit 1

Repro: test/repro/maintainer_gap_dom_element_ns_properties.php

Done when

• prefix / namespaceURI correct for createElementNS() elements (and update on rename if applicable per php-src)
• Repro exits 0; compliance guard under test/compliance/cases/stdlib/dom_*
