* Create an XML DOM element.
*
* This function creates an XML DOM element correctly across all

* document.createElement makes DOM elements with 43+ default attributes
* unless elements are created with the ActiveX object Microsoft.XMLDOM.
*
* Most DOMs force element names to lowercase, so we use the
* _realname attribute on the created element to store the case
* sensitive name. This is required to generate proper XML for
* things like vCard avatars (XEP 153). This attribute is stripped
* out before being sent over the wire or serialized, but you may
* notice it during debugging.
*
* Parameters:
* (String) name - The name for the element.
* (Array) attrs - An optional array of key/value pairs to use as
* element attributes in the following format [['key1', 'value1'],
* ['key2', 'value2']]
* (String) text - The text child data for the element.
*
* Returns:
* A new XML DOM element.

博客分享了Jabber客户端开发，提到之前有jabber－net开源项目，使用xmltextreader。博主开发的客户端未采用其为核心，而是用XmlSerializer，此方法利于后续开发，但前期工作多且该工具本身有缺点，可自行编写serializer实现。还给出联系方式。
