External Entities and SAX2 Parser
Hi,
Do we need to set any properties or features to turn on parsing
of external entities using the xerces c++(sax2) parsers?
I am getting a segfault for parsing a document that contains an
external entity(specified using http protocol) such as:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE DOCUMENT [
<!ELEMENT DOCUMENT (TITLE, SIGNATURE)>
<!ELEMENT TITLE (#PCDATA)>
<!ELEMENT COPYRIGHT (#PCDATA)>
<!ELEMENT EMAIL (#PCDATA)>
<!ELEMENT SIGNATURE (COPYRIGHT, EMAIL)>
<!ENTITY SIG SYSTEM
"http://www-edm/remote/svr/xmltestdir.sri/signature.xml">
]>
<DOCUMENT>
<TITLE>Entity references</TITLE>
&SIG;
</DOCUMENT>
Basically, at the following line of code:
decl.setBaseURI((*lastInfo.systemId) ? lastInfo.systemId : 0);
in DTDScanner.cpp method scanEntityDef()
basically systemId is null.
The segfault is at:
