#31076 [NEW]: schemaValidate crashing on empty xs:token

From: c dot d at earthlink dot net Operating system: Mac OS X 10.3.6 PHP version: 5.0.2 PHP Bug Type: DOM XML related Bug description: schemaValidate crashing on empty xs:token Description: ------------ When an XML file has an empty element defined as xs:token in XSD, and it is loaded into a DOMDocument and then schemaValidate is called, the server CPU begins to race and content is never returned to browser. The W3C definition of xs:token does not prohibit empty xs:token elements. Reproduce code: --------------- $aDOM = new DOMDocument("1.0"); $aDOM->load("file.xml"); $aDOM->schemaValidate("file.xsd"); XML File: <?xml version="1.0"?> <people> <person> <fname>John</fname> <mname/> <lname>Doe</lname> </person> </people> XSD File: <?xml version="1.0" encoding="ISO-8859-1"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="people"> <xs:complexType> <xs:sequence> <xs:element name="person" type="persontype" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> </xs:element> <xs:complexType name="persontype"> <xs:sequence> <xs:element name="fname" type="xs:token"/> <xs:element name="mfname" type="xs:token"/> <xs:element name="lfname" type="xs:token"/> </xs:sequence> </xs:complexType> </xs:schema> Expected result: ---------------- schemaValidate should return true. Actual result: -------------- CPU races, server does not return content to browser. -- Edit bug report at http://bugs.php.net/?id=31076&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31076&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31076&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31076&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31076&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31076&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31076&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31076&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31076&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31076&r=support Expected behavior: http://bugs.php.net/fix.php?id=31076&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31076&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31076&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31076&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31076&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31076&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31076&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31076&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31076&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=31076&r=mysqlcfg
