我有一个(大)的XML文件集,我想搜索一组字符串都存在 - 我试图使用以下Python代码做到这一点:os.scandir给出[WinError 3]系统找不到指定的路径
import collections
thestrings = []
with open('Strings.txt') as f:
for line in f:
text = line.strip()
thestrings.append(text)
print('Searching for:')
print(thestrings)
print('Results:')
try:
from os import scandir
except ImportError:
from scandir import scandir
def scantree(path):
"""Recursively yield DirEntry objects for given directory."""
for entry in scandir(path):
if entry.is_dir(follow_symlinks=False) and (not entry.name.startswith('.')):
yield from scantree(entry.path)
else:
yield entry
if __name__ == '__main__':
for entry in scantree('//path/to/folder'):
if ('.xml' in entry.name) and ('.zip' not in entry.name):
with open(entry.path) as f:
data = f.readline()
if (thestrings[0] in data):
print('')
print('****** Schema found in: ', entry.name)
print('')
data = f.read()
if (thestrings[1] in data) and (thestrings[2] in data) and (thestrings[3] in data):
print('Hit at:', entry.path)
print("Done!")
哪里Strings.txt是我有兴趣,找到字符串的文件,并且第一行是架构URI。
这似乎在第一次运行正常,但在几秒钟后给了我:
FileNotFoundError: [WinError 3] The system cannot find the path specified: //some/path
这是困惑我,因为路径运行期间,兴建?
注意,如果我仪器代码如下:
with open(entry.path) as f:
data = f.readline()
if (thestrings[0] in data):
要成为:
with open(entry.path) as f:
print(entry.name)
data = f.readline()
if (thestrings[0] in data):
然后我看到发生错误之前被人发现一些潜在的文件。
可能的路径开头的双斜杠'//一些/ path'解释作为远程SMB路径,如'\\ server \ shared'?然后你无法访问名为'path'或'some'的服务器。 – rodrigo
附注:你的'scantree'函数正在重新发明'os.walk'。 –
@rodrigo,如图所示,它是一个UNC路径,但这种情况下可能的错误是'ERROR_BAD_NET_NAME'(67)。获取'ERROR_PATH_NOT_FOUND'(3)意味着本地设备名称不存在(例如列出未映射的驱动器盘符)或未找到路径组件 - 除非最终组件未找到,则错误为“ERROR_FILE_NOT_FOUND” (2)。 – eryksun
