Detailed Description

Receives QAbstractXmlReceiver events and validates that they are correct, before sending them on to a second QAbstractXmlReceiver.

Currently, this is only checking that attributes appear before other nodes.

}

endDocument()

void OutputValidator::endDocument ( )

virtual

End of a document node.

Implements QPatternist::QAbstractXmlReceiver.

Definition at line 143 of file qoutputvalidator.cpp.
