Bug #70962 [NEW]: xml_parse_into_struct strips embedded whitespace with XML_OPTION_SKIP_WHITE

From: dwilks at intacct dot com Operating system: OSX 10.9.4 PHP version: 7.0.0RC7 Package: *XML functions Bug Type: Bug Bug description:xml_parse_into_struct strips embedded whitespace with XML_OPTION_SKIP_WHITE Description: ------------ XML_OPTION_SKIP_WHITE should skip elements if the entire element is whitespace. Unfortunately it looks like expat calls the character handler on individual xml entities within a string so any whitespace between xml entities is ignored. Looks like the hhvm guys noticed and "fixed this" Test script: --------------- @ https://3v4l.org/4TD9v also <?php function handleCharacterData($parser, $data) { echo __FUNCTION__ . " - " . $data . "\n"; } function handleElementStart($parser, $name, $attributes) { echo __FUNCTION__ . " - " . $name . "\n"; } function handleElementEnd($parser, $name) { echo __FUNCTION__ . " - " . $name . "\n"; } function parseAndOutput($s) { $p = xml_parser_create(); xml_parser_set_option($p, XML_OPTION_SKIP_WHITE, 1); xml_set_character_data_handler($p, 'handleCharacterData'); xml_set_element_handler($p, 'handleElementStart', 'handleElementEnd'); xml_parse_into_struct($p, $s, $values); echo $values[0]['value'] . "\n\n"; } $s = "<a>b\nc</a>"; parseAndOutput($s); $s = "<a>&lt;b&gt;\n&lt;c&gt;</a>"; parseAndOutput($s); Expected result: ---------------- handleElementStart - A handleCharacterData - b c handleElementEnd - A b c handleElementStart - A handleCharacterData - <b> <c> handleElementEnd - A <b> <c> Actual result: -------------- handleElementStart - A handleCharacterData - b c handleElementEnd - A b c handleElementStart - A handleCharacterData - < handleCharacterData - b handleCharacterData - > handleCharacterData - handleCharacterData - < handleCharacterData - c handleCharacterData - > handleElementEnd - A <b><c> -- Edit bug report at https://bugs.php.net/bug.php?id=70962&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70962&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70962&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70962&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70962&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70962&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70962&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70962&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70962&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70962&r=support Expected behavior: https://bugs.php.net/fix.php?id=70962&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70962&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70962&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70962&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70962&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70962&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70962&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70962&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70962&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70962&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70962&r=mysqlcfg
