#38410 [Fbk->Opn]: PHP Interpreter Crash with schemaValidate on XML with CDATA sections.

ID: 38410 User updated by: adam at sccode dot com Reported By: adam at sccode dot com -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: Windows 2000/XP/2003 PHP Version: 5.1.4 New Comment: Using the latest Windows Snapshot (5.2.0RC2-dev - Build: Aug 10 2006 16:15:11) I receive the same error. Note that removing the whitespace before the CDATA section does eliminate the problem and could be used as a workaround: Crashes interpreter: <?xml version="1.0"?> <test xmlns="http://www.php.net/bugtests"> <value> <![CDATA[ test ]]> </value> </test> Works: <?xml version="1.0"?> <test xmlns="http://www.php.net/bugtests"> <value><![CDATA[ test ]]> </value> </test> As the XML specification allows for whitespace after tags, I don't think the interpreter should crash upon encountering these.

Example: <?xml version="1.0"?> <test xmlns="http://www.php.net/bugtests"> <value> <![CDATA[ test ]]> </value> </test> Validating the schema using xmllint with libxml 2.6.22 DLL works as expected and does not crash. I found a similar, possibly the same bug (http://bugs.php.net/bug.php?id=37435&edit=2) which has been closed. As I could not reproduce it with xmllint, I figure that it must be the PHP interpreter. Reproduce code: --------------- crash-test.php: <?php $xml = new DOMDocument('1.0'); $xml->load('crash-test.xml'); $xml->schemaValidate('crash-test.xsd'); // crash here ?> crash-test.xml: <?xml version="1.0"?> <test xmlns="http://www.php.net/bugtests"> <value> <![CDATA[ test ]]> </value> </test> crash-test.xsd: <?xml version="1.0" encoding="UTF-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.php.net/bugtests" xmlns="http://www.php.net/bugtests" elementFormDefault="qualified"> <xs:element name="test"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="value" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> Expected result: ---------------- validated schema Actual result: -------------- php interpreter crashes with exception ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38410&edit=1
