<h2>Description</h2>
<div class="description">
<p>Interface for an <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> filter. </p>
<p>An <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> filter is like an <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> reader, except that it obtains its events from another <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> reader  rather than a primary source like an <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> document or database. Filters can modify a stream of  events as they pass on to the final application. </p>
<p>The <a href="Poco.XML.XMLFilterImpl.html" title="class Poco::XML::XMLFilterImpl">XMLFilterImpl</a> helper class provides a convenient base for creating SAX2 filters, by passing on  all <a href="Poco.XML.EntityResolver.html" title="class Poco::XML::EntityResolver">EntityResolver</a>, <a href="Poco.XML.DTDHandler.html" title="class Poco::XML::DTDHandler">DTDHandler</a>, <a href="Poco.XML.ContentHandler.html" title="class Poco::XML::ContentHandler">ContentHandler</a> and <a href="Poco.XML.ErrorHandler.html" title="class Poco::XML::ErrorHandler">ErrorHandler</a> events automatically. </p>

<p class="decl">virtual <a href="Poco.XML.XMLReader.html" title="class Poco::XML::XMLReader">XMLReader</a> * getParent() const = 0;</p>
<div class="description">
<p>Set the parent reader. </p>
<p>This method allows the application to link the filter to a parent reader (which may be another  filter). The argument may not be null. </p>

<div class="description">
<p>Get the parent reader. </p>
<p>This method allows the application to query the parent reader (which may be another filter).  It is generally a bad idea to perform any operations on the parent reader directly: they should  all pass through this filter. </p>
