<hr><a name="details"></a><h2>Detailed Description</h2>
The QXmlErrorHandler class provides an interface to report
errors in XML data.
<p>
<p> If you want your application to report errors to the user or to
perform customized error handling, you should subclass this class.
<p> You can set the error handler with <a href="qxmlreader.html#setErrorHandler">QXmlReader::setErrorHandler</a>().
<p> Errors can be reported using <a href="#warning">warning</a>(), <a href="#error">error</a>() and <a href="#fatalError">fatalError</a>(),
with the error text being reported with <a href="#errorString">errorString</a>().
<p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.
<p> <p>See also <a href="qxmldtdhandler.html">QXmlDTDHandler</a>, <a href="qxmldeclhandler.html">QXmlDeclHandler</a>, <a href="qxmlcontenthandler.html">QXmlContentHandler</a>, <a href="qxmlentityresolver.html">QXmlEntityResolver</a>, <a href="qxmllexicalhandler.html">QXmlLexicalHandler</a>, and <a href="xml-tools.html">XML</a>.

<h3 class=fn>bool <a name="error"></a>QXmlErrorHandler::error ( const <a href="qxmlparseexception.html">QXmlParseException</a> & exception )<tt> [pure virtual]</tt>
</h3>
<p> A reader might use this function to report a recoverable error. A
recoverable error corresponds to the definiton of "error" in
section 1.2 of the XML 1.0 specification. Details of the error are
stored in <em>exception</em>.
<p> The reader must continue to provide normal parsing events after
invoking this function.
<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><a href="qstring.html">QString</a> <a name="errorString"></a>QXmlErrorHandler::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="fatalError"></a>QXmlErrorHandler::fatalError ( const <a href="qxmlparseexception.html">QXmlParseException</a> & exception )<tt> [pure virtual]</tt>
</h3>
<p> A reader must use this function to report a non-recoverable error.
Details of the error are stored in <em>exception</em>.
<p> If this function returns TRUE the reader might try to go on
parsing and reporting further errors; but no regular parsing
events are reported.
<h3 class=fn>bool <a name="warning"></a>QXmlErrorHandler::warning ( const <a href="qxmlparseexception.html">QXmlParseException</a> & exception )<tt> [pure virtual]</tt>
</h3>
<p> A reader might use this function to report a warning. Warnings are
conditions that are not errors or fatal errors as defined by the
XML 1.0 specification. Details of the warning are stored in <em>exception</em>.
<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.
