<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class Namespace</h1><p class="nomargin-top"></p>
<pre class="base-tree">
object --+
|
<strong class="uidshort">Namespace</strong>
</pre>
<hr />
<p>Utility class creating and testing elements with a namespace.</p>
<p>Internally, namespace URIs are encoded in the <a href="genshi.core.QName-class.html" class="link">QName</a> of any element or
attribute, the namespace URI being enclosed in curly braces. This class
helps create and test these strings.</p>
<p>A <a href="genshi.core.Namespace-class.html" class="link">Namespace</a> object is instantiated with the namespace URI.</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>html = Namespace(<span class="py-string">'http://www.w3.org/1999/xhtml'</span>)
<span class="py-prompt">>>> </span>html
<span class="py-output"><Namespace "http://www.w3.org/1999/xhtml"></span>
<span class="py-output"></span><span class="py-prompt">>>> </span>html.uri
<span class="py-output">u'http://www.w3.org/1999/xhtml'</span></pre>
<p>The <a href="genshi.core.Namespace-class.html" class="link">Namespace</a> object can than be used to generate <a href="genshi.core.QName-class.html" class="link">QName</a> objects with
that namespace:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>html.body
<span class="py-output">QName(u'http://www.w3.org/1999/xhtml}body')</span>
<span class="py-output"></span><span class="py-prompt">>>> </span>html.body.localname
<span class="py-output">u'body'</span>
<span class="py-output"></span><span class="py-prompt">>>> </span>html.body.namespace
<span class="py-output">u'http://www.w3.org/1999/xhtml'</span></pre>
<p>The same works using item access notation, which is useful for element or
attribute names that are not valid Python identifiers:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>html[<span class="py-string">'body'</span>]
<span class="py-output">QName(u'http://www.w3.org/1999/xhtml}body')</span></pre>
<p>A <a href="genshi.core.Namespace-class.html" class="link">Namespace</a> object can also be used to test whether a specific <a href="genshi.core.QName-class.html" class="link">QName</a>
belongs to that namespace using the <tt class="rst-docutils literal"><span class="pre">in</span></tt> operator:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>qname = html.body
<span class="py-prompt">>>> </span>qname <span class="py-keyword">in</span> html
<span class="py-output">True</span>
<span class="py-output"></span><span class="py-prompt">>>> </span>qname <span class="py-keyword">in</span> Namespace(<span class="py-string">'http://www.w3.org/2002/06/xhtml2'</span>)
<span class="py-output">False</span></pre>
