Using this class, an application programmer can obtain a <A HREF="../../../org/w3c/dom/Document.html"><CODE>Document</CODE></A> from XML.<p> An instance of this class can be obtained from the <A HREF="../../../javax/xml/parsers/DocumentBuilderFactory.html#newDocumentBuilder()"><CODE>DocumentBuilderFactory.newDocumentBuilder</CODE></A> method. Once an instance of this class is obtained, XML can be parsed from a variety of input sources. These input sources are InputStreams, Files, URLs, and SAX InputSources.<p> 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 <code>Document</code>. It merely requires that the implementation communicate with the application using these existing APIs. <p> An implementation of <code>DocumentBuilder</code> is <em>NOT</em> guaranteed to behave as per the specification if it is used concurrently by two or more threads. It is recommended to have one instance of the <code>DocumentBuilder</code> per thread or it is upto the application to make sure about the use of <code>DocumentBuilder</code> from more than one thread.<P><DL><DT><B>Since: </B><DD>JAXP 1.0</DD><DT><B>Version: </B><DD>1.0</DD></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ========
