该函数使得 <code class="parameter">parser</code> 指定的解析器可以被用在 <code class="parameter">object</code> 对象中。所有的回叫函数（callback function）都可以由 <span class="function"><a href="xml_set_element_handler.html" class="function">xml_set_element_handler()</a></span> 等函数来设置，它们被假定为 <code class="parameter">object</code> 对象的方法。
