Bug #68454 [NEW]: ID already defined errors after update to anything after 1.1.26

From: x9sim9 at hotmail dot com Operating system: PHP version: 5.4.35 Package: XSLT related Bug Type: Bug Bug description:ID already defined errors after update to anything after 1.1.26 Description: ------------ This issue has already been well documented on stack exchange so I thought it made sense to add the link here instead: http://stackoverflow.com/questions/25893393/xsltprocessortransformtoxml-id-already-defined/27023224#27023224 The issue seems to have been created by fixing an existing bug and that the XHTML is now being treated as XML whereas older versions were treated as HTML. I am hoping a compatibility flag or similar could be implemented so that codebases built on this flaw can still operate. Test script: --------------- XML demonstrating the issue (rare) <x> <my_tag id="1234" id="4567">aaa</my_tag> </x> XSL demonstrating the issue (more common) <xsl:template match="/"> <div id="1234">aaa</div> <!-- further down the code --> <div id="1234">bbbb</div> </xsl:template> Expected result: ---------------- Render the HTML Actual result: -------------- XSLT ERROR OCCURED: XSLTProcessor::transformToXml() [xsltprocessor.transformtoxml]: ID already defined -- Edit bug report at https://bugs.php.net/bug.php?id=68454&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68454&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68454&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68454&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68454&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68454&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68454&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68454&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68454&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68454&r=support Expected behavior: https://bugs.php.net/fix.php?id=68454&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68454&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68454&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68454&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68454&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68454&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68454&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68454&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68454&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68454&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68454&r=mysqlcfg
