DocumentParserUsingDomLS

DOM-LS-based Document parser.

Typical non-trivial creation is as follows, assuming class MyEntityResolver, which extends LSResourceResolver, and class MyErrorHandler, which extends DOMErrorHandler:

def createParser(domImplLS: DOMImplementationLS): LSParser = {
  val parser = domImplLS.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS, null)
  parser.getDomConfig.setParameter("resource-resolver", new MyEntityResolver)
  parser.getDomConfig.setParameter("error-handler", new MyErrorHandler)
  parser
}

val domParser = DocumentParserUsingDomLS.newInstance().withParserCreator(createParser _)

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

class MyEntityResolver extends LSResourceResolver {
  override def resolveResource(tpe: String, namespaceURI: String, publicId: String, systemId: String, baseURI: String): LSInput = {
    val input = domImplLS.createLSInput()
    // This dirty hack may not work on IBM JVMs
    input.setCharacterStream(new jio.StringReader(""))
    input
  }
}

For completeness, a custom DOMErrorHandler class that simply throws an exception:

class MyErrorHandler extends DOMErrorHandler {
  override def handleError(exc: DOMError): Boolean = {
    sys.error(exc.toString)
  }
}

If more flexibility is needed in configuring the DocumentParser than offered by this class, consider writing a wrapper DocumentParser which wraps a DocumentParserUsingDomLS, but adapts the parse method.

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