I'm using Xerces2-J to parse an XML document into a DOM. My application
is XML Schema aware, and the XML documents that my app is parsing are
defined via a schema.
When my application reads the XML document, it installs an ErrorHandler
to catch parsing errors. However, I noticed that schema validation
errors are caught by the very same interface
(ErrorHandler.error(SAXParseException) and friends), so I can't
determine if the error was a validation error or a parse error. The only
possiblity I see to programmatically distinguish between the two is to
parse the error message string, which hardly seems like a good solution
to me.
Is there another interface that I can use that allows me to do some more
specific error handling?
Not Xerces specific, but you should probably get more familiar with
the XML terminology [1]. "Parsing errors" are called
well-formedness errors. They are reported as fatal errors
<http://www.saxproject.org/apidoc/org/xml/sax/ErrorHandler.html#fatalError(org.xml.sax.SAXParseException)>,
<http://java.sun.com/javase/6/docs/api/org/xml/sax/ErrorHandler.html#fatalError(org.xml.sax.SAXParseException)>,
<http://xerces.apache.org/xerces2-j/javadocs/api/org/xml/sax/ErrorHandler.html#fatalError(org.xml.sax.SAXParseException)>:
Receive notification of a non-recoverable error.
This corresponds to the definition of "fatal error" in section 1.2
of the W3C XML 1.0 Recommendation. For example, a parser would use
this callback to report the violation of a well-formedness
constraint.
Xerces doesn't continue parsing after reporting a fatal error, by
default.
Validation errors are re are reported as errors
<http://www.saxproject.org/apidoc/org/xml/sax/ErrorHandler.html#error(org.xml.sax.SAXParseException)>,
<http://java.sun.com/javase/6/docs/api/org/xml/sax/ErrorHandler.html#error(org.xml.sax.SAXParseException)>,
<http://xerces.apache.org/xerces2-j/javadocs/api/org/xml/sax/ErrorHandler.html#error(org.xml.sax.SAXParseException)>:
Receive notification of a recoverable error.
This corresponds to the definition of "error" in section 1.2 of the
W3C XML 1.0 Recommendation. For example, a validating parser would
use this callback to report the violation of a validity constraint.
