生成xml格式内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <username>admin</username>
  <password>123456</password>
  <transcationID>3</transcationID>
  <msg_time>4</msg_time>
  <msgID>5</msgID>
  <Msg_type>6</Msg_type>
  <Src_addr>7</Src_addr>
  <Dst_addr>8</Dst_addr>
  <LinkID>9</LinkID>
  <ServiceIOD>10</ServiceIOD>
  <content>11</content>
  <pushurl>12</pushurl>
</root>
解析xml格式内容如下:
username:admin
password:123456
transcationID:3
msg_time:4
msgID:5
Msg_type:6
Src_addr:7
Dst_addr:8
LinkID:9
ServiceIOD:10
content:11
pushurl:12
