RE: [xml-dev] CDATA processing problem using Xerces-J validating parser

["Dare Obasanjo" <dareo@microsoft.com>]

It is a common misconception that information within a CDATA section is not processed by the XML parser but instead is skipped. Unfortunately this is incorrect. CDATA sections are at best a shorthand mechanism that prevents having to escape certain characters not a directive to the XML parser to halt processing until further notice.

Subject: [xml-dev] CDATA processing problem using Xerces-J validating parser


I have a XML doc instance that contains CDATA section:
"<![CDATA[" and ends with "]]>"
 
Parsers validating this XML are supposed to ignore the
CDATA. XML Spy validates the XML instance fine using
its corresponding XSD which defines the CDATA as
a xsd:string.
 
Now when I use in run-time Xeres-J parser it seems to
be processing the CDATA and obviously fails to
validate the CDATA section since it has all types of
illegal characters in it:
 
Here is the error I get:
 
org.xml.sax.SAXException: Data not belonging to any element encountered: 32.com Record
 
Any ideas why this is a problem.
 
I believe this may be a Xerces 1.4 parser. Does xerces support
correct handling of CDATA???

thanks
