Direct Known Subclasses:
  DOMParser, DOMParserImpl

public class AbstractDOMParser
extends AbstractXMLDocumentParser

This is the base class of all DOM parsers. It implements the XNI callback methods to create the DOM tree. After a successful parse of an XML document, the DOM Document object can be queried using the `getDocument` method. The actual pipeline is defined in parser configuration.

### setDocumentClassName

    protected void setDocumentClassName(java.lang.String documentClassName)

  This method allows the programmer to decide which document factory to use when constructing the DOM tree. However, doing so will lose the functionality of the default factory. Also, a document class other than the default will lose the ability to defer node expansion on the DOM tree produced.

  See Also:
    `getDocumentClassName()`, `DEFAULT_DOCUMENT_CLASS_NAME`

  Parameters:
    `name` - The name of the general entity.
    `identifier` - The resource identifier.
    `encoding` - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal entities or a document entity that is parsed from a java.io.Reader).

  Notifies of the presence of a TextDecl line in an entity. If present, this method will be called immediately following the startEntity call.

  Note: This method will never be called for the document entity; it is only called for external general entities referenced in document content.

  Note: This method is not called for entity references appearing as part of attribute values.

  Parameters:
    `version` - The XML version, or null if not specified.

                               throws org.apache.xerces.xni.XNIException

  A processing instruction. Processing instructions consist of a target name and, optionally, text data. The data is only meaningful to the application.

  Typically, a processing instruction's data will contain a series of pseudo-attributes. These pseudo-attributes follow the form of element attributes but are not parsed or presented to the application as anything other than text. The application is responsible for parsing the data.

  Overrides:
    `processingInstruction` in class `AbstractXMLDocumentParser`
  Parameters:
    `target` - The target.
    `data` - The data or null if none specified.
    `augs` - Additional information that may include infoset augmentations

  Parameters:
    `locator` - The system identifier of the entity if the entity is external, null otherwise.
    `encoding` - The auto-detected IANA encoding name of the entity stream. This value will be null in those situations where the entity encoding is not auto-detected (e.g. internal entities or a document entity that is parsed from a java.io.Reader).
    `namespaceContext` - The namespace context in effect at the start of this document. This object represents the current context. Implementors of this class are responsible for copying the namespace bindings from the the current context (and its parent contexts) if that information is important.
    `augs` - Additional information that may include infoset augmentations
  Throws:
    `org.apache.xerces.xni.XNIException` - Thrown by handler to signal an error.
