|
||
<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("rdfxml");
|
||
</pre>
|
||
<p>
|
||
or the name can be discovered from an <span class="emphasis"><em>enumeration</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="raptor-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(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("http://www.dajobe.org/2004/01/turtle/");
|
||
rdf_parser = raptor_new_parser_for_content(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(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(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.
