[英]Python xml.etree.ElementTree directory acess
import xml.etree.ElementTree as ET
ID="000296166"
tree = ET.parse("\folder" + ID +'.xml')
root = tree.getroot()
What I'm trying to do is access XML files that aren't in the same folder as the .py
using the function from xml.etree.elementtree
我想要做的是使用
xml.etree.elementtree
的函数xml.etree.elementtree
与.py
不在同一文件夹中的XML文件
It keeps giving the error: 它不断给出错误:
IOError: [Errno 22] invalid mode ('rb') or filename: '\x0colder000296166.xml'
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 我一直觉得自己在编写路径时做错了什么...但是我找不到在线示例来了解它应该如何工作
\\f
is interpreted as the page brake and is replaced with hex code 0xC
. \\f
被解释为页面制动器,并用十六进制代码0xC
代替。 You should remove leading backslash from path. 您应该从路径中删除前导反斜杠。
tree = ET.parse("folder" + ID +'.xml')
And if you use backslash inside strings it can be escaped like this \\\\
如果在字符串中使用反斜杠,则可以像这样
\\\\
EDIT 编辑
When you work with paths it is better to use os.path module: 使用路径时,最好使用os.path模块:
import os
...
tree = ET.parse(os.path.join('folder', ID + '.xml'))
