<?xml version="1.0" encoding="utf-8"?>
 <res>
 <item igid="luoql_happy">
  <info name="pwd" value="111111" /> 
  <info name="sex" value="1" /> 
  <info name="nick" value="" /> 
  <info name="email" value="[e-mail]" /> 
  <info name="truename" value="sdfas" /> 
  <info name="phone" value="1-1" /> 
  <info name="mobile" value="" /> 
  <info name="usermark" value="2" /> 
<member>
<item id="89443">
<![CDATA[ 户主
  ]]> 
  </item>
  </member>
  </item>
  </res>
