boost读取xml文件

参考：https://www.2cto.com/kf/201210/162103.html

conf.xml 注：文件放在当前项目根就行了

xml version="1.0" encoding="utf-8"?>
<root> 
  <strage name="asd" alias="13" classId="13.22">r 
    <id>12</id>   
    <name>"jack"</name>   
    <accout>"0001"</accout> 
  </strage> 
 <strage name="abbasd" alias="14" classId="14.22">abb 
    <id >13</id>   
    <name>"toni"</name>   
    <accout>"0002"</accout> 
  </strage> 
 <strage name="assasd" alias="15" classId="15.44">ass
