Class SimpleXMLResource

java.lang.Object
  org.xmldb.api.sdk.modules.BaseResource
      org.xmldb.api.sdk.modules.SimpleXMLResource

All Implemented Interfaces:

Resource, XMLResource

Direct Known Subclasses:

XMLResourceImpl

public abstract class SimpleXMLResource

extends BaseResource

implements XMLResource

Provides access to XML resources stored in the database. An XMLResource can be accessed either as text XML or via the DOM or SAX APIs.

The default behavior for getContent and setContent is to work with XML data as text so these methods work on String content.
