路径 C# 到 Ironpython 中的非法字符

Question

我正在尝试将包含文件路径的变量从我的 C# 应用程序传递到我的 Python 脚本中的 temp.xml 文件，但我不断收到 Illegal Characters in Path 异常。我觉得我已经完成了 Stackoverflow 上提到的几乎所有事情，以修复 C# 端和 Python 端的非法字符/路径，但似乎没有任何效果。我该如何克服这个障碍！？

这是我用来打开/替换坏字符并将temp.xml写入C:\Temp\目录的C#代码：

StreamReader sr1 = new StreamReader(filePath);
string tempFile = @"C:\Temp\temp.xml";

File.Copy(filePath, tempFile, true);
StreamWriter sw = new StreamWriter(tempFile);
sw.AutoFlush = true;

string xml = sr1.ReadToEnd();
string regExp = @"</(\w+)>";
MatchCollection mc = Regex.Matches(xml, regExp);
foreach (Match m in mc)
{
    string val = m.Groups[1].Value;
    string regExp2 = "<" + val + "( |>)";
    Match m2 = Regex.Match(xml, regExp2);
    if (m2.Success)
    {
         char[] chars = xml.ToCharArray();
         chars[m2.Index] = '~';
         xml = new string(chars);
         xml = Regex.Replace(xml, @"</" + val + ">", "~/" + val + ">");
    }

         xml = Regex.Replace(xml, @"<\?", @"~?"); // declarations
         xml = Regex.Replace(xml, @"<!", @"~!");   // comments
 }

   string regExp3 = @"<\w+\s?/>";
   Match m3 = Regex.Match(xml, regExp3);
   if (m3.Success)
   {
       char[] chars = xml.ToCharArray();
       chars[m3.Index] = '~';
       xml = new string(chars);
   }

     xml = Regex.Replace(xml, "&gt;|-&gt;", ">");
     xml = Regex.Replace(xml, "&lt;", "<");
     xml = Regex.Replace(xml, "~", "<");
     xml = Regex.Replace(xml, "&", "&");
     xml = Regex.Replace(xml, "“|”", "\"");
     xml = Regex.Replace(xml, "’", "'");
     xml = Regex.Replace(xml, "‘", "\"");
     xml = Regex.Replace(xml, "–", "-");
     sw.WriteLine(xml);
     sw.Close();

     ScriptEngine engine = Python.CreateEngine();
     ScriptScope scope = engine.CreateScope();
     var paths = engine.GetSearchPaths();
     paths.Add(@"C:\Program Files (x86)\IronPython 2.7\Lib");
     engine.SetSearchPaths(paths);

     var parameters = new Dictionary<string, object>()
     {
       {"scapFilePath", tempFile}, {"scapProfile", profile}
     };
     scope = engine.CreateScope(parameters);

     //EXCEPTION IS THROWN HERE
     try
     {
         dynamic result = engine.ExecuteFile("xccdf-xml2tsv.py", scope);
     }
     catch (Exception e)
     {
          Messagebox.Show(e.toString());
     }

     Console.WriteLine("Press any key to exit");
     Console.ReadKey();
}

这是我在 python 脚本中处理上面定义的 scope 变量的代码：

import csv
import sys
import os
import traceback
reload(sys)
sys.setdefaultencoding('utf-8')
import xml.etree.ElementTree as ET
xmlns = "http://checklists.nist.gov/xccdf/1.1"

scapFile = os.path.normpath(scapFilePath)

try:
    xml = ET.parse(scapFile)
except Exception,e:
    traceback.print_exc()
    sys.exit(-1)

这是我当前的scope 变量在异常发生时：

这是一个例外：

感谢任何帮助；我已经坚持了两天了！！

在带有变量的屏幕截图中

["outFileName"]

显示为包含

"c:\\Temp\tmp.csv"

所以它包含一个制表符而不是第二个反斜杠（在 tmp.csv 之前）
