Python xml.etree.ElementTree目录访问 [英] Python xml.etree.ElementTree directory acess

问题描述

import xml.etree.ElementTree as ET

ID="000296166"
tree = ET.parse("\folder" + ID +'.xml')
root = tree.getroot()

我想做的是使用xml.etree.elementtree

它一直显示错误:

IOError: [Errno 22] invalid mode ('rb') or filename: '\x0colder000296166.xml'

我一直感觉自己在编写路径时做错了事...但是我无法在网上找到任何示例来了解它应该如何工作

I keep getting the feeling that I did something wrong when writing the path...but I can't find any examples online to see how it's supposed to work

推荐答案

\f被解释为页面制动器，并用十六进制代码0xC代替.您应该从路径中删除前导反斜杠.

\f is interpreted as the page brake and is replaced with hex code 0xC. You should remove leading backslash from path.

tree = ET.parse("folder" + ID +'.xml')

如果在字符串中使用反斜杠，则可以像这样\\

And if you use backslash inside strings it can be escaped like this \\

编辑

使用路径时，最好使用os.path模块:

When you work with paths it is better to use os.path module:

 import os 
 ...
 tree = ET.parse(os.path.join('folder', ID + '.xml'))
