xstream 使用方式

xml文件内容：

<list>
  <storagePool>
    <name>isopool</name>
    <path>/vms/isos</path>
    <type>dir</type>
    <totalSize>4983</totalSize>
    <freeSize>4810</freeSize>
    <status>1</status>
  </storagePool>
  <storagePool>
    <name>defaultpool</name>
    <path>/vms/images</path>
    <type>dir</type>
    <totalSize>4983</totalSize>
    <freeSize>4771</freeSize>
    <status>1</status>
  </storagePool>
</list>
