<hr><h2><a name="details"></a>Detailed Description</h2>
The QXmlDTDHandler class provides an interface to report DTD content of XML data.
<p>
If an application needs information about notations and unparsed entities,
then the application implements this interface and registers an instance with
<a href="qxmlreader.html#174b4a">QXmlReader::setDTDHandler</a>().
<p>Note that this interface includes only those DTD events that the XML
recommendation requires processors to report: notation and unparsed entity
declarations.
<p>See also the <a href="xml.html#introSAX2">Introduction to SAX2</a>.
<p>See also <a href="qxmldeclhandler.html">QXmlDeclHandler</a>, <a href="qxmlcontenthandler.html">QXmlContentHandler</a>, <a href="qxmlentityresolver.html">QXmlEntityResolver</a>, <a href="qxmlerrorhandler.html">QXmlErrorHandler</a> and <a href="qxmllexicalhandler.html">QXmlLexicalHandler</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a href="qstring.html">QString</a><a name="387bff"></a>QXmlDTDHandler::errorString() <code>[virtual]</code></h3>
<p>The reader calls this function to get an error string if any of the handler
functions returns FALSE to him.
<p>Reimplemented in <a href="qxmldefaulthandler.html#5181fd">QXmlDefaultHandler</a>.
<h3 class="fn">bool<a name="9a58a7"></a>QXmlDTDHandler::notationDecl(const<a href="qstring.html">QString</a>&name, const<a href="qstring.html">QString</a>&publicId, const<a href="qstring.html">QString</a>&systemId) <code>[virtual]</code></h3>
<p>The reader calls this function when he has parsed a notation
declaration.
<p>The argument <em>name</em> is the notation name, <em>publicId</em> is the notations's
public identifier and <em>systemId</em> is the notations's system identifier.
<p>If this function returns FALSE the reader will stop parsing and will report
an error. The reader will use the function <a href="#387bff">errorString</a>() to get the error
message that will be used for reporting the error.
<p>Reimplemented in <a href="qxmldefaulthandler.html#4794fb">QXmlDefaultHandler</a>.
<h3 class="fn">bool<a name="08734e"></a>QXmlDTDHandler::unparsedEntityDecl(const<a href="qstring.html">QString</a>&name, const<a href="qstring.html">QString</a>&publicId, const<a href="qstring.html">QString</a>&systemId, const<a href="qstring.html">QString</a>&notationName) <code>[virtual]</code></h3>
<p>The reader calls this function when he finds an unparsed entity declaration.
<p>The argument <em>name</em> is the unparsed entity's name, <em>publicId</em> is the
entity's public identifier, <em>systemId</em> is the entity's system identifier and
<em>notation</em> is the name of the associated notation.
<p>If this function returns FALSE the reader will stop parsing and will report
an error. The reader will use the function <a href="#387bff">errorString</a>() to get the error
message that will be used for reporting the error.
