Bug #77651 [NEW]: DOMDocument preserves insignificant whitespace text nodes

From: morozov at tut dot by Operating system: Windows PHP version: 7.3.2 Package: DOM XML related Bug Type: Bug Bug description:DOMDocument preserves insignificant whitespace text nodes Description: ------------ DOMDocument::loadHTML() produces different results on Windows and Linux. Whitespace text nodes are ignored between non-inline elements on Linux but not on Windows. The different behaviors are observed on the same PHP version (7.3.2) and very close libxml versions (2.9.3 on Linux and 2.9.8 on Windows). Test script: --------------- $doc = new DOMDocument(); $doc->loadHTML( <<<HTML <html> <body> <map> <area /> </map> <div> <span /> </div> </body> </html> HTML ); var_dump( $doc->getElementsByTagName('map') ->item(0) ->childNodes ->length ); var_dump( $doc->getElementsByTagName('div') ->item(0) ->childNodes ->length ); Expected result: ---------------- int(1) int(3) Actual result: -------------- int(3) int(3) -- Edit bug report at https://bugs.php.net/bug.php?id=77651&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77651&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77651&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77651&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77651&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77651&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77651&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77651&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77651&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77651&r=support Expected behavior: https://bugs.php.net/fix.php?id=77651&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77651&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77651&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77651&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77651&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77651&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77651&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77651&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77651&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77651&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77651&r=mysqlcfg
