[python]修改文件夹下xml文件IOError: [Errno 2] No such file or directory: ‘bbb.xml‘

        cc.py是修改xml文件脚本，../xmlfile是xml的存放路径

执行python cc.py 1.2  ../xmlfile/出现如下错误

root# python cc.py 1.2 ../xmlfile/
1.2
New version=1.2
['bbb.xml', 'config_1.xml', 'config.xml', 'ddd.xml', 'ccc.xml']
Traceback (most recent call last):
  File "cc.py", line 17, in
    dom = xml.dom.minidom.parse(sfile)
  File "/usr/lib/python2.7/xml/dom/minidom.py", line 1918, in parse
    return expatbuilder.parse(file)
  File "/usr/lib/python2.7/xml/dom/expatbuilder.py", line 922, in parse
    fp = open(file, 'rb')
IOError: [Errno 2] No such file or directory: 'bbb.xml'

        这是由于sfile只是bbb.xml没有包含路径，脚本在当前文件夹下查找，所以找不到

将

  dom = xml.dom.minidom.parse(sfile)

修改为

  dom = xml.dom.minidom.parse(path+sfile)
