问c#从XML中删除字符串

EN

string s = @"<z:row ID=""1""
   Author=""2;#Bruce, Banner""
   Editor=""1;#Bruce, Banner""
   FileRef=""1;#Reports/Pipeline Tracker Report.xltm"" 
   FileDirRef=""1;#Reports"" 
   Last_x0020_Modified=""1;#2014-04-04 12:05:56""

    />";

string result = Regex.Replace(s,"\"([0-9];#)","");

private string FilterValue(string input)
{
    // If the string does not contain #, return value
    if (!input.Contains("#"))
        return input;

    // # does exist in the string so 
    // 1) find its location
    // 2) Read everything from that point to the end of the string
    // 3) Return the SubString value
    var index = input.IndexOf("#", StringComparison.Ordinal) + 1;
    return input.Substring(index, input.Length - index);
}

// same logic then M Patel.
// This one will fit only if you have three items to remove (one digit, one semi-colon and one sharp).
// use M Patel solution
string CleanElement(string elem)
{
    return elem.Substring(3, elem.Length - 3);
}

// slower I guess but still a solution
string CleanElement(string elem)
{
     string[] strs = elem.Split('#');
     strs[0] = "";
     return string.Join("", strs);
}
