[嗨，我正在尝试使用python解析给定目录中的所有XML文件。我能够一次解析一个文件，但是由于文件数量太多，这对我来说是“不可能的”，即当我预定义树和根时它可以工作，但是当我尝试全部运行时就无法工作代码。
这是我到目前为止实现的：
import xml.etree.ElementTree as ET
import os
directory = "C:/Users/danie/Desktop/NLP/blogs/"
def clean_dir(directory):
path = os.listdir(directory)
print(path)
for filename in path:
tree = ET.parse(filename)
root = tree.getroot()
doc_parser(root)
post_list = []
def doc_parser(root):
for child in root.findall('post'):
post_list.append(child.text)
clean_dir(directory)
print(post_list[0])
我得到的错误如下：
File "D:\Anaconda\envs\Deep Learning New\lib\site-packages\IPython\core\interactiveshell.py", line 3326, in run_code
exec(code_obj, self.user_global_ns, self.user_ns)
File "<ipython-input-91-fce6b0119ea7>", line 1, in <module>

File "D:\Anaconda\envs\Deep Learning New\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 827, in runfile

File "D:\Anaconda\envs\Deep Learning New\lib\site-packages\spyder_kernels\customize\spydercustomize.py", line 110, in execfile
exec(compile(f.read(), filename, 'exec'), namespace)
File "C:/Users/danie/Desktop/NLP/blogs/Parser_Tes.py", line 19, in <module>
clean_dir(directory)
File "C:/Users/danie/Desktop/NLP/blogs/Parser_Tes.py", line 9, in clean_dir
tree = ET.parse(filename)
File "D:\Anaconda\envs\Deep Learning New\lib\xml\etree\ElementTree.py", line 1196, in parse
tree.parse(source, parser)
File "D:\Anaconda\envs\Deep Learning New\lib\xml\etree\ElementTree.py", line 597, in parse
self._root = parser._parse_whole(source)
File "<string>", line unknown
ParseError: not well-formed (invalid token): line 103, column 225
关于打印路径，将打印所有正确的文件名。其中一些是：

所以我接受了@wundermahn和@Kevin的建议，并使用try ... except。现在是输出。即19320个项目中的482个。现在的问题是，当我尝试从列表post_list[]中打印出某个元素时。我收到以下错误：
IndexError: list index out of range
有错误的文件：

再次感谢！
@@ Kevin在他的评论中是正确的，此错误与ElementTree object无法正确解析文档有关。某些东西不是“ true ElementTree”，它可能只是像一个奇怪的非Unicode字符之类的简单东西。
您可以尝试帮助调试的是：
XML添加import xml.etree.ElementTree as ET
import os
directory = "C:/Users/danie/Desktop/NLP/blogs/"
def clean_dir(directory):
path = os.listdir(directory)
print(path)
for filename in path:
try:
tree = ET.parse(filename)
root = tree.getroot()
doc_parser(root)
except:
print("ERROR ON FILE: {}".format(filename))
post_list = []
def doc_parser(root):
for child in root.findall('post'):
post_list.append(child.text)
clean_dir(directory)
print(post_list[0])
语句将尝试每个文件，如果有错误，请打印出引起该错误的文件。
我没有要测试的任何数据，但这应该可以修复错误。
