<p>The parser can be created directly from a known name such as
<code class="literal">rdfxml</code> for the W3C Recommendation RDF/XML syntax:
</p>
<pre class="programlisting">
raptor_parser* rdf_parser;
rdf_parser = raptor_new_parser(world, "rdfxml");
</pre>
<p>
or the name can be discovered from an <span class="emphasis"><em>description</em></span>
as discussed in <a class="link" href="tutorial-querying-functionality.html" title="Listing built-in functionality">Querying Functionality</a>
</p>
<p>The parser can also be created by identifying the syntax by a
URI, specifying the syntax by a MIME Type, providng an identifier for
the content such as filename or URI string or giving some initial
content bytes that can be used to guess.
Using the
<a class="link" href="raptor2-section-parser.html#raptor-new-parser-for-content" title="raptor_new_parser_for_content ()"><code class="function">raptor_new_parser_for_content()</code></a>
function, all of these can be given as optional parameters, using NULL
or 0 for undefined parameters. The constructor will then use as much of
this information as possible.
</p>
<pre class="programlisting">
raptor_parser* rdf_parser;
</pre>
<p>Create a parser that reads the MIME Type for RDF/XML
<code class="literal">application/rdf+xml</code>
</p>
<pre class="programlisting">
rdf_parser = raptor_new_parser_for_content(world, NULL, "application/rdf+xml", NULL, 0, NULL);
</pre>
<p>
</p>
<p>Create a parser that can read a syntax identified by the URI
for Turtle <code class="literal">http://www.dajobe.org/2004/01/turtle/</code>,
which has no registered MIME Type at this date:
</p>
<pre class="programlisting">
syntax_uri = raptor_new_uri(world, "http://www.dajobe.org/2004/01/turtle/");
rdf_parser = raptor_new_parser_for_content(world, syntax_uri, NULL, NULL, 0, NULL);
</pre>
<p>
</p>
<p>Create a parser that recognises the identifier <code class="literal">foo.rss</code>:
</p>
<pre class="programlisting">
rdf_parser = raptor_new_parser_for_content(world, NULL, NULL, NULL, 0, "foo.rss");
</pre>
<p>
</p>
<p>Create a parser that recognises the content in <span class="emphasis"><em>buffer</em></span>:
</p>
<pre class="programlisting">
rdf_parser = raptor_new_parser_for_content(world, NULL, NULL, buffer, len, NULL);
</pre>
<p>
</p>
<p>Any of the constructor calls can return NULL if no matching
parser could be found, or the construction failed in another way.
