<hr><a name="details"></a><h2>Detailed Description</h2>
The TQXmlDTDHandler class provides an interface to report
DTD content of XML data.
<p>
<p> If an application needs information about notations and unparsed
entities, it can implement this interface and register an instance
with <a href="qxmlreader.html#setDTDHandler">TQXmlReader::setDTDHandler</a>().
<p> Note that this interface includes only those DTD events that the
XML recommendation requires processors to report, i.e. notation
and unparsed entity declarations using <a href="#notationDecl">notationDecl</a>() and
<a href="#unparsedEntityDecl">unparsedEntityDecl</a>() respectively.
<p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.
<p> <p>See also <a href="qxmldeclhandler.html">TQXmlDeclHandler</a>, <a href="qxmlcontenthandler.html">TQXmlContentHandler</a>, <a href="qxmlentityresolver.html">TQXmlEntityResolver</a>, <a href="qxmlerrorhandler.html">TQXmlErrorHandler</a>, <a href="qxmllexicalhandler.html">TQXmlLexicalHandler</a>, and <a href="xml-tools.html">XML</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a href="qstring.html">TQString</a> <a name="errorString"></a>TQXmlDTDHandler::errorString ()<tt> [pure virtual]</tt>
</h3>
<p> The reader calls this function to get an error string if any of
the handler functions returns FALSE.
<h3 class=fn>bool <a name="notationDecl"></a>TQXmlDTDHandler::notationDecl ( const <a href="qstring.html">TQString</a> & name, const <a href="qstring.html">TQString</a> & publicId, const <a href="qstring.html">TQString</a> & systemId )<tt> [pure virtual]</tt>
</h3>
<p> The reader calls this function when it has parsed a notation
declaration.
<p> The argument <em>name</em> is the notation name, <em>publicId</em> is the
notation's public identifier and <em>systemId</em> is the notation's
system identifier.
<p> If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
get the error message.
<h3 class=fn>bool <a name="unparsedEntityDecl"></a>TQXmlDTDHandler::unparsedEntityDecl ( const <a href="qstring.html">TQString</a> & name, const <a href="qstring.html">TQString</a> & publicId, const <a href="qstring.html">TQString</a> & systemId, const <a href="qstring.html">TQString</a> & notationName )<tt> [pure virtual]</tt>
</h3>
<p> The reader calls this function when it 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>notationName</em> is the name of the associated
notation.
<p> If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
get the error message.
