Hi,
to import an xml file I use a DOMBuilder (Xerces version 2.7). When I parse an
invalid XML file, I do not get an exception an the DOMDocument is also no
NULL pointer. But then the method getDocumentElement gives a NULL pointer. Is
this an error in the Xerces library?
This is my code:
> -------------------
try {
this->parseXML( infile );
} catch ( XMLException& e ) {
d4err << "Xerces XML Exception: " << XercesString(
e.getMessage() ) <<
endmsg;
throw XmlParseException( "XML parsing" );
} catch ( DOMException& e ) {
d4err << "Xerces DOM parser Exception: " << XercesString(
e.getMessage() )
<< endmsg;
throw XmlParseException( "XML parsing" );
}
void ADSFile::parseXML( const helper::UnixPath& infile_ )
throw( XmlDbException, XMLException, DOMException ) {
XMLInit initXML;
XMLCh tmpStr[100];
XMLString::transcode( "LS", tmpStr, 99 );
DOMImplementationLS* impl =
DOMImplementationRegistry::getDOMImplementation( tmpStr );
DOMBuilder* parser =
dynamic_cast<DOMImplementationLS*>( impl )->createDOMBuilder(
DOMImplementationLS::MODE_SYNCHRONOUS,
0 );
if (parser->canSetFeature(XMLUni::fgDOMValidation, true))
parser->setFeature(XMLUni::fgDOMValidation, true);
if (parser->canSetFeature(XMLUni::fgDOMNamespaces, true))
parser->setFeature(XMLUni::fgDOMNamespaces, true);
if (parser->canSetFeature(XMLUni::fgDOMDatatypeNormalization, true))
parser->setFeature(XMLUni::fgDOMDatatypeNormalization,
true);
DOMDocument* doc;
doc = parser->parseURI( infile_.to_s().c_str() );
if ( ! doc ) {
throw XmlParseException( "Parsing of XML file failed!" );
}
DOMElement* root = doc->getDocumentElement();
XercesString rootName( root->getNodeName() );
...
}
> -----------------------
Here I get a segmentation violation. I thought that the parser would throw a
XMLException or a DOMException which I caught above. Or it would deliver a
NULL pointer for the DOMDocument at least.
Is this an error in the xerces library or have I done something wrong?
Thanks, Sven
