url解码后：

Html将一些特殊字符(Html语法字符)的一种表达方式。

下面列举几个常用字符：

&nbsp;  空格

&amp;   &

&lt;       <

&gt;      >

&quot;   "

&qpos;   '

对&lt;和&gt;处理，得到：

<?xml version="1.0"?><object><string name="id">c:1447059862152</string><object name="attrs"><string name="account">"李"<tips1057@163.com></string><boolean name="showOneRcpt">false</boolean><array name="to"><string>"tips1057@126.com"<tips1057@126.com></string></array><array name="cc"/><array name="bcc"/><string name="subject">特使</string><boolean name="isHtml">true</boolean><string name="content"><div style="line-height:1.7;color:#000000;font-size:14px;font-family:Arial">特使的不好使用</div></string><int name="priority">3</int><boolean name="saveSentCopy">true</boolean><string name="charset">GBK</string></object><boolean name="returnInfo">false</boolean><string name="action">deliver</string><int name="saveTextThreshold">1048576</int></object>

对于content，其实我们关注的是text正文，怎么把html文档转换为txt呢？

用正则表达式可以处理这个问题：
把"<[^>]*>"替换为""， refer to http://www.cnblogs.com/noblepaul/archive/2004/09/25/46532.aspx。
