Error IDs

• SAXParseException has a new getExceptionId() method to identify which kind of error is being reported:

  public String getExceptionId()

• Since diagnostic message vary between parsers, these identifiers are URIs so parsers can define nonstandard IDs.

• Standard IDs look like:

  • http://xml.org/sax/exception/xml/rule-66

  • http://xml.org/sax/exception/xml/wfc-PEInInternalSubset

  • http://xml.org/sax/exception/xml/vc-roottype

  • http://xml.org/sax/exception/xml/nsc-NSDeclared

• http://xml.org/sax/exception/xml/rule-number indicates a BNF grammar violation by production

• http://xml.org/sax/exception/xml/wfc-id indicates a well-formedness constraint violation by ID attribute

• http://xml.org/sax/exception/xml/vc-id indicates a validity constraint violation by ID attribute

• http://xml.org/sax/exception/xmlns/nsc-id indicates a namespace violation by ID attribute

• Some well-formedness violations can be attributed to more than one grammar rule. The most specific applicable rule should be used.
