Idea for the ErrorHandler

[Brad O'Hearne]

In the ErrorHandler class, it would be very handy to have some additional information sent to the error, fatalError, and warning methods, such as a reference to the element stack, the element name, and/or a byte offset in the stream, if that is being maintained.  Take for instance the following Exception I report from my ErrorHandler:   org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x19) was found in the element content of the document.  at org.apache.xerces.framework.XMLParser.reportError(XMLParser.java:969)  at org.apache.xerces.framework.XMLDocumentScanner.reportFatalXMLError(XMLDocumentScanner.java:643)  at org.apache.xerces.framework.XMLDocumentScanner$ContentDispatcher.dispatch(XMLDocumentScanner.java:1355)  at org.apache.xerces.framework.XMLDocumentScanner.parseSome(XMLDocumentScanner.java:380)  at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:861)   It would be really nice to know what element caused this problem, and further, which occurrence of that element caused the problem.  I actually am maintaining my own element stack for handling purposes, and so it looks like I will probably store a reference to this stack in my ErrorHandler class.  However, I would think this type of information would be wanted by everyone, and hence, possibly a helpful change to the source.   BradO
