python使用elementTree拼接xml（主从健康检查结果合并）

nhc.xml

支持主机显示从机检查结果，且不改变现有接口文件形式
现有结果用*分隔列，用：分隔列名和检测结果
在检测结果里增加从机结果，用/分隔

    Check Result:Pass*Version:11*PatchLevel:3*GDBVersion:7.5
    Check Result:Pass

# coding = utf-8
import xml.etree.ElementTree as ElementTree

slave_tree = ElementTree.ElementTree(file=slave_result_file)
local_root = local_tree.getroot()
slave_root = slave_tree.getroot()

# 打印root的标签
# 打印结果

# 打印root的属性
# 打印结果
# {'type': 'omc'}

# 打印child的属性
# 打印结果
