[xml] Parameter-Entity in CDATA block not getting replaced

[Ashwin <ashwins huawei com>]

Hi,

       For the attached files the parameter entity inside the CDATA block is not getting replaced.

Ideally after replacement the CDATA content should be <!ATTLIST root attr1 NMTOKEN "attrvalue">, however the PE entity replacement is going wrong and the content is being returned as NULL. The problem occurs at line 2314 in parser.c, there is a function call to xmlParseStringPEReference, for the PE inside the Cdata block, which in turn calls the xmlGetParameterEntity, and then does a hashlookup, from the xmlGetEntityFromTable function. However the entity pointer returned contains the content as Empty instead of <!ATTLIST root attr1 NMTOKEN "attrvalue">. I think the content should not be empty, its probably happening because somehow the parser is not able to read the entity content in external2.ent….

 

Regards

Ashwin
