Class XmlDocument

java.lang.Object
  org.jvoicexml.xml.XmlDocument

All Implemented Interfaces:

Serializable, Document, Node

Direct Known Subclasses:

CcxmlDocument, PlsDocument, SrgsXmlDocument, SsmlDocument, VoiceXmlDocument

public abstract class XmlDocument
extends Object
implements Document, Serializable

An XML Document abstract base class.

VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony and mixed initiative conversations. Its major goal is to bring the advantages of web-based development and content delivery to interactive voice response applications.

Objects of this class can create such VoiceXML documents or parse them.

The encoding can be controlled via the jvoicexml.xml.encoding environment property. The default value is UTF-8.

Entities are not resolved by default. The bahavior can be controlled via the system property org.jvoicexml.resolveEntities.
