Bug #72052 [NEW]: DOM truncates XML namespace prefixes to 20 characters

From: fg at numlog dot fr Operating system: Linux Debian 8.4 PHP version: 5.6.20 Package: DOM XML related Bug Type: Bug Bug description:DOM truncates XML namespace prefixes to 20 characters Description: ------------ First : my PHP version is 5.6.19, but it's not listed above. When using DOMNode::replaceChild or DOMNode::appendChild or DOMNode::insertBefore in order to insert a node which includes long namespace prefixes (ex. : "variable_trade_item_information:variableTradeItemInformationModule"), the prefix is truncate to 20 characters. In this example it becomes "variable_trade_item_:variableTradeItemInformationModule". When inserting such a node, DOM also adds in the root tag of the node all the definitions of the prefix used in the node. This bunch of prefix definitions include the same truncated prefixes. May be this header is created because the truncated prefixes are not declared (after they have been truncated), as their definitions in the tag itself are not truncated. Ex; : <variable_trade_item_:variableTradeItemInformationModule xmlns:variable_trade_item_information="urn:gs1:gdsn:variable_trade_item_information:xsd:3" ... (snipped) > Test script: --------------- Sorry but my test script depends on large XML file... -- Edit bug report at https://bugs.php.net/bug.php?id=72052&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72052&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72052&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72052&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72052&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72052&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72052&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72052&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72052&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72052&r=support Expected behavior: https://bugs.php.net/fix.php?id=72052&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72052&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72052&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72052&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72052&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72052&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72052&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72052&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72052&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72052&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72052&r=mysqlcfg
