|

<p>Raptor can use namespace prefix/URIs to abbreviate syntax
|
||
in some syntaxes such as Turtle or any XML syntax including RDF/XML,
|
||
RSS1.0 and Atom 1.0. These are declared
|
||
with <a class="link" href="raptor-section-serializer.html#raptor-serialize-set-namespace" title="raptor_serialize_set_namespace ()"><code class="function">raptor_serialize_set_namespace()</code></a>
|
||
using a prefix and URI argument pair like this:
|
||
</p>
|
||
<pre class="programlisting">
|
||
const unsigned char* prefix="ex";
|
||
raptor_uri* uri=raptor_new_uri("http://example.org");
|
||
|
||
raptor_serialize_set_namespace(rdf_serializer, prefix, uri);
|
||
</pre>
|
||
<p>
|
||
</p>
|
||
<p>or
|
||
<a class="link" href="raptor-section-serializer.html#raptor-serialize-set-namespace-from-namespace" title="raptor_serialize_set_namespace_from_namespace ()"><code class="function">raptor_serialize_set_namespace_from_namespace()</code></a>
|
||
from an existing namespace. This can be useful when connected up the
|
||
the namespace declarations that are generated from a parser via a
|
||
namespace handler set with
|
||
<a class="link" href="raptor-section-parser.html#raptor-set-namespace-handler" title="raptor_set_namespace_handler ()"><code class="function">raptor_set_namespace_handler()</code></a>
|
||
</p>
|
||
like this:
|
||
<pre class="programlisting">
|
||
static void
|
||
relay_namespaces(void* user_data, raptor_namespace *nspace)
|
||
{
|

raptor_serialize_set_namespace_from_namespace(rdf_serializer, nspace);
|
||
}
|
||
|
||
rdf_parser=raptor_new_parser(syntax_name);
|

raptor_set_namespace_handler(rdf_parser, rdf_serializer, relay_namespaces);
