<hr><a name="details"></a><h2>Detailed Description</h2>
The TQXmlEntityResolver class provides an interface to
resolve external entities contained in XML data.
<p>
<p> If an application needs to implement customized handling for
external entities, it must implement this interface, i.e.
<a href="#resolveEntity">resolveEntity</a>(), and register it with
<a href="tqxmlreader.html#setEntityResolver">TQXmlReader::setEntityResolver</a>().
<p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.
<p> <p>See also <a href="tqxmldtdhandler.html">TQXmlDTDHandler</a>, <a href="tqxmldeclhandler.html">TQXmlDeclHandler</a>, <a href="tqxmlcontenthandler.html">TQXmlContentHandler</a>, <a href="tqxmlerrorhandler.html">TQXmlErrorHandler</a>, <a href="tqxmllexicalhandler.html">TQXmlLexicalHandler</a>, and <a href="xml-tools.html">XML</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="errorString"></a>TQXmlEntityResolver::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="resolveEntity"></a>TQXmlEntityResolver::resolveEntity ( const <a href="tqstring.html">TQString</a> & publicId, const <a href="tqstring.html">TQString</a> & systemId, <a href="tqxmlinputsource.html">TQXmlInputSource</a> *& ret )<tt> [pure virtual]</tt>
</h3>
<p> The reader calls this function before it opens any external
entity, except the top-level document entity. The application may
request the reader to resolve the entity itself (<em>ret</em> is 0) or
to use an entirely different input source (<em>ret</em> points to the
input source).
<p> The reader deletes the input source <em>ret</em> when it no longer needs
it, so you should allocate it on the heap with <tt>new</tt>.
<p> The argument <em>publicId</em> is the public identifier of the external
entity, <em>systemId</em> is the system identifier of the external
entity and <em>ret</em> is the return value of this function. If <em>ret</em>
is 0 the reader should resolve the entity itself, if it is
non-zero it must point to an input source which the reader uses
instead.
<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.
