<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class ElementFactory</h1><p class="nomargin-top"></p>
<pre class="base-tree">
object --+
|
<strong class="uidshort">ElementFactory</strong>
</pre>
<hr />
<p>Factory for <a href="genshi.builder.Element-class.html" class="link">Element</a> objects.</p>
<p>A new element is created simply by accessing a correspondingly named
attribute of the factory object:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>factory = ElementFactory()
<span class="py-prompt">>>> </span><span class="py-keyword">print</span> factory.foo
<span class="py-output"><foo/></span>
<span class="py-output"></span><span class="py-prompt">>>> </span><span class="py-keyword">print</span> factory.foo(id=2)
<span class="py-output"><foo id="2"/></span></pre>
<p>Markup fragments (lists of nodes without a parent element) can be created
by calling the factory:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span><span class="py-keyword">print</span> factory(<span class="py-string">'Hello, '</span>, factory.em(<span class="py-string">'world'</span>), <span class="py-string">'!'</span>)
<span class="py-output">Hello, <em>world</em>!</span></pre>
<p>A factory can also be bound to a specific namespace:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>factory = ElementFactory(<span class="py-string">'http://www.w3.org/1999/xhtml'</span>)
<span class="py-prompt">>>> </span><span class="py-keyword">print</span> factory.html(lang=<span class="py-string">"en"</span>)
<span class="py-output"><html xmlns="http://www.w3.org/1999/xhtml" lang="en"/></span></pre>
<p>The namespace for a specific element can be altered on an existing factory
by specifying the new namespace using item access:</p>
<pre class="py-doctest">
<span class="py-prompt">>>> </span>factory = ElementFactory()
<span class="py-prompt">>>> </span><span class="py-keyword">print</span> factory.html(factory[<span class="py-string">'http://www.w3.org/2000/svg'</span>].g(id=3))
<span class="py-output"><html><g xmlns="http://www.w3.org/2000/svg" id="3"/></html></span></pre>
<p>Usually, the <a href="genshi.builder.ElementFactory-class.html" class="link">ElementFactory</a> class is not be used directly. Rather, the
<a href="genshi.builder-module.html#tag" class="link">tag</a> instance should be used to create elements.</p>
