<p>Each parser plugin may support multiple RDF serializations (<a class="el" href="classSoprano_1_1Parser.html#af405712d025ac44dc84a8ebb08ce12e1">supportedSerializations()</a>).</p>

Usage</h2>
<p>Using a <a class="el" href="classSoprano_1_1Parser.html" title="Soprano::Parser defines the interface for a Soprano RDF parser plugin.">Parser</a> is straightforward. One starts by getting a plugin that supports the requested RDF data serialization:</p>
<div class="fragment"><pre class="fragment"> <a class="code" href="classSoprano_1_1Parser.html" title="Soprano::Parser defines the interface for a Soprano RDF parser plugin.">Soprano::Parser</a>* p = <a class="code" href="classSoprano_1_1PluginManager.html#a922c00336d39542a289e9b82a39e25b2">Soprano::PluginManager::instance</a>()->discoverParserForSerialization( <a class="code" href="namespaceSoprano.html#a870b14710c2cc2b825b4b287f01a35e0a1e1568be674d28e0e0712e8a36dca70f">Soprano::SerializationRdfXml</a> );
</pre></div><p>Then parsing RDF data is done in a single method call resulting in a <a class="el" href="classSoprano_1_1StatementIterator.html" title="An iterator that provides a stream of Statements.">StatementIterator</a> over the resulting graph (since parsers may support multiple serializations one always needs to provide the serialization type unless a parser plugin support autodetection).</p>
