DGXMLScanner cannot cope with " in attribute values
--------------------------------------------------------
Key: XERCESC-1597
URL: http://issues.apache.org/jira/browse/XERCESC-1597
Project: Xerces-C++
Type: Bug
Components: Validating Parser (DTD)
Versions: 2.7.0
Environment: 64-bit
Solaris 10
Sun CC: Sun C++ 5.7 Patch 117830-07 2006/03/15
Reporter: Michael Fuller
Priority: Minor
The Xerces 2.7.0 DGXMLScanner cannot cope with " in attribute values.
The following XML document:
% cat test.xml
<!DOCTYPE doc [
<!ELEMENT doc (document-type*)>
<!ATTLIST doc search CDATA #REQUIRED>
<!ELEMENT document-type (#PCDATA)>
]>
<doc search="""></doc>
fails to parse when the the DGXMLScanner is used. Non-Xerces parsers
and other Xerces scanners can (correctly) validate this document.
The bug can be trivially reproduced by modifying the 2.7.0 sample "SAX2Print"
to explicitly use the DGXMLScanner (by setting the relevant SAX2 property):
