<P>
Interface for reading an XML document using callbacks.
<blockquote>
<em>This module, both source code and documentation, is in the
Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
</blockquote>
<p><strong>Note:</strong> despite its name, this interface does
<em>not</em> extend the standard Java <CODE>Reader</CODE>
interface, because reading XML is a fundamentally different activity
than reading character data.</p>
<p>XMLReader is the interface that an XML parser's SAX2 driver must
implement. This interface allows an application to set and
query features and properties in the parser, to register
event handlers for document processing, and to initiate
a document parse.</p>
<p>All SAX interfaces are assumed to be synchronous: the
<A HREF="../../../org/xml/sax/XMLReader.html#parse(org.xml.sax.InputSource)"><CODE>parse</CODE></A> methods must not return until parsing
is complete, and readers must wait for an event-handler callback
to return before reporting the next event.</p>
<p>This interface replaces the (now deprecated) SAX 1.0 <A HREF="../../../org/xml/sax/Parser.html"><CODE>Parser</CODE></A> interface. The XMLReader interface
contains two important enhancements over the old Parser
interface:</p>
<ol>
<li>it adds a standard way to query and set features and
properties; and</li>
<li>it adds Namespace support, which is required for many
higher-level XML standards.</li>
</ol>
<p>There are adapters available to convert a SAX1 Parser to
a SAX2 XMLReader and vice-versa.</p>
