java.lang.Object javax.xml.parsers.DocumentBuilder
Defines the API to obtain DOM Document instances from an XML
document. Using this class, an application programmer can obtain a
Document
from XML.
An instance of this class can be obtained from the
DocumentBuilderFactory.newDocumentBuilder()
method. Once
an instance of this class is obtained, XML can be parsed from a
variety of input sources. These input sources are InputStreams
and SAX InputSources.
Note that this class reuses several classes from the SAX API. This
does not require that the implementor of the underlying DOM
implementation use a SAX parser to parse XML document into a
Document
. It merely requires that the implementation
communicate with the application using these existing APIs.
