#25838 [NEW]: Dom_Node->child_nodes() is not live as the W3C DOM specification demands

From: Martin dot Honnen at arcor dot de Operating system: Windows XP PHP version: 4.3.3 PHP Bug Type: DOM XML related Bug description: Dom_Node->child_nodes() is not live as the W3C DOM specification demands Description: ------------ The W3C DOM Level 2 specification at http://www.w3.org/TR/DOM-Level-2-Core/core.html#td-live says about NodeList collections that they should be live, meaning if a DOM user gets a NodeList object containing the children of an Element, then subsequently adds more children to that element (or removes children, or modifies them), those changes are automatically reflected in the NodeList, without further action on the user's part. However my test with PHP 4.3.3 and the following settings for DOMXML DOM/XML enabled DOM/XML API Version 20020815 libxml Version 20507 HTML Support enabled XPath Support enabled XPointer Support enabled DOM/XSLT enabled libxslt Version 1.0.30 libxslt compiled against libxml Version 2.5.7 shows that the result returned from Node->child_nodes() is not live but static. Reproduce code: --------------- <?php function dumpDoc ($xmlDocument) { echo "<p><pre>\n"; echo htmlentities($xmlDocument->dump_mem(true)); echo "</pre></p>\n"; } $xmlDocument = domxml_new_doc("1.0"); $rootElement = $xmlDocument->create_element("gods"); $xmlDocument->append_child($rootElement); $childNodes = $rootElement->child_nodes(); echo 'count($childNodes): ' . count($childNodes) . "<br>\n"; $xmlDocument->append_child($rootElement); for ($i = 0; $i < 5; $i++) { $god = $xmlDocument->create_element("god"); $god->set_attribute("name", "god $i"); $rootElement->append_child($god); dumpDoc($xmlDocument); echo 'count($childNodes): ' . count($childNodes) . "<br>\n"; } ?> Expected result: ---------------- I would expect count($childNodes) to be incremented every time $rootElement->append_child($god) is called. That is what the W3C DOM understands to be a live collection, and that is what happens with conformant DOM implementations (as the one in Mozilla or the one in SUN's Java SDK 1.4). Actual result: -------------- The output with dump_mem shows that child elements are added but the output of count($childNodes) is always 0. -- Edit bug report at http://bugs.php.net/?id=25838&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25838&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25838&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25838&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25838&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25838&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25838&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25838&r=support Expected behavior: http://bugs.php.net/fix.php?id=25838&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25838&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25838&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25838&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25838&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25838&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25838&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25838&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25838&r=float
