提问by Alice Duff
I have built this code to specifically identify a load of .XML files and to extract co-ordinates from those files. Here is my code:
我构建了这段代码来专门识别 .XML 文件的负载并从这些文件中提取坐标。这是我的代码：
from xml.etree import ElementTree as ET
import sys, string, os, arcgisscripting
gp = arcgisscripting.create(9.3)
workspace = "D:/J040083"
gp.workspace = workspace
for root, dirs, filenames in os.walk(workspace): # returms root, dirs, and files
for filename in filenames:
filename_split = os.path.splitext(filename) # filename and extensionname (extension in [1])
filename_zero = filename_split[0]
extension = str.upper(filename_split[1])
try:
first_2_letters = str.upper(filename_zero[0] + filename_zero[1])
except:
first_2_letters = "XX"
if first_2_letters == "LI" and extension == ".XML":
tree = ET.parse(workspace)
print tree.find('//{http://www.opengis.net/gml}lowerCorner').text
print tree.find('//{http://www.opengis.net/gml}upperCorner').text
I am having trouble with an error:
我遇到了错误：

I definitely do have access to this folder! I have also tried making new, empty folders and putting just one .xml file in there but i get the same error! Does anyone have any idea what has gone wrong?
我绝对可以访问这个文件夹！我也尝试过创建新的空文件夹并在其中只放入一个 .xml 文件，但我遇到了同样的错误！有谁知道出了什么问题？

You need to change the line
你需要改变行
tree = ET.parse(workspace)
to
到
tree = ET.parse(filename)
because workspace is a directory and the parse method takes a filename.
因为工作区是一个目录，解析方法采用文件名。

Maybe you just need to write the file path with \instead of /:
也许您只需要使用\而不是编写文件路径/：
workspace = "D:\J040083"
Or, without backslash escaping as a raw string:
或者，没有反斜杠作为原始字符串转义：
workspace = r"D:\J040083"
