DocumentParserUsingStax

final class DocumentParserUsingStax extends AbstractDocumentParser

StAX-based Document parser.

Typical non-trivial creation is as follows, assuming a class MyXmlResolver, which extends XMLResolver, and a class MyXmlReporter, which extends XMLReporter:

val xmlInputFactory = XMLInputFactory.newFactory()
xmlInputFactory.setProperty(XMLInputFactory.IS_COALESCING, java.lang.Boolean.TRUE)
xmlInputFactory.setXMLResolver(new MyXmlResolver)
xmlInputFactory.setXMLReporter(new MyXmlReporter)

val docParser = DocumentParserUsingStax.newInstance(xmlInputFactory)

A custom XMLResolver could be used to retrieve DTDs locally, or even to suppress DTD resolution. The latter can be coded as follows (compare with http://stuartsierra.com/2008/05/08/stop-your-java-sax-parser-from-downloading-dtds), risking some loss of information:

class MyXmlResolver extends XMLResolver {
override def resolveEntity(publicId: String, systemId: String, baseUri: String, namespace: String): Any = {
  // This dirty hack may not work on IBM JVMs
  new java.io.StringReader("")
}
}

A trivial XMLReporter could look like this:

class MyXmlReporter extends XMLReporter {
override def report(message: String, errorType: String, relatedInformation: AnyRef, location: Location): Unit = {
  println("Location: %s. Error type: %s. Message: %s.".format(location, errorType, message))
}
}

If more flexibility is needed in configuring the DocumentParser than offered by this class, consider writing a wrapper DocumentParser which wraps a DocumentParserUsingStax, but adapts the parse method. This would make it possible to adapt the conversion from StAX events to yaidom Document, for example.

A DocumentParserUsingStax instance can be re-used multiple times, from the same thread. If the XMLInputFactory is thread-safe, it can even be re-used from multiple threads. Typically a XMLInputFactory cannot be trusted to be thread-safe, however. In a web application, one (safe) way to deal with that is to use one XMLInputFactory instance per request.
