如何检索包含以@"anystring"&#x9开头的字符串的目录文件

Question

我在c:/dom/xml中有xml文件。我只想搜索所有包含文本或字符串的xml文件，以@"anystring“开头。

示例:下面的标记显示在xml文件中，我需要过滤包含文本的xml文件名。

<parameter ID="**@Id_name&#x9**;&#x9;" >

我试过在下面

  static void Main(string[] args)
    {
        string sourceFolder = @"C:\dom\Xml";
        string searchWord = "&#x9";

        List<string> allFiles = new List<string>();
        AddFileNamesToList(sourceFolder, allFiles);
        foreach (string fileName in allFiles)
        {
            string contents = File.ReadAllText(fileName);
            if (contents.Contains(searchWord))
            {
                Console.WriteLine(fileName);
            }
        }

        Console.WriteLine(" ");
        System.Console.ReadKey();
    }

    public static void AddFileNamesToList(string sourceDir, List<string> allFiles)
    {

        string[] fileEntries = Directory.GetFiles(sourceDir);
        foreach (string fileName in fileEntries)
        {
            allFiles.Add(fileName);
        }

        //Recursion    
        string[] subdirectoryEntries = Directory.GetDirectories(sourceDir);
        foreach (string item in subdirectoryEntries)
        {
            // Avoid "reparse points"
            if ((File.GetAttributes(item) & FileAttributes.ReparsePoint) != FileAttributes.ReparsePoint)
            {
                AddFileNamesToList(item, allFiles);
            }
        }

    }

但我需要像“@Anystring”这样的词

希望下面的代码能对你有所帮助。

 static void Main(string[] args)
    {
        string sourceFolder = @"C:\dom";
        string searchWord = "&#x9";            
        string regexPattern = @"@([A-Za-z0-9\-_]+).\&#x9";


        List<string> allFiles = new List<string>();
        AddFileNamesToList(sourceFolder, allFiles);
        foreach (string fileName in allFiles)
        {
            string contents = File.ReadAllText(fileName);
            if (showMatch(contents, regexPattern))
            {
                if (contents.Contains(searchWord))
                {
                    Console.WriteLine(fileName);
                }
            }
        }

        Console.WriteLine(" ");
        System.Console.ReadKey();
    }

    private static bool showMatch(string text, string expr)
    {
        Console.WriteLine("The Expression: " + expr);
        MatchCollection mc = Regex.Matches(text, expr);
        foreach (Match m in mc)
        {
            Console.WriteLine(m);
        }
        return mc.Count > 0;
    }

    public static void AddFileNamesToList(string sourceDir, List<string> allFiles)
    {

        string[] fileEntries = Directory.GetFiles(sourceDir);
        foreach (string fileName in fileEntries)
        {
            allFiles.Add(fileName);
        }

        //Recursion    
        string[] subdirectoryEntries = Directory.GetDirectories(sourceDir);
        foreach (string item in subdirectoryEntries)
        {
            // Avoid "reparse points"
            if ((File.GetAttributes(item) & FileAttributes.ReparsePoint) != FileAttributes.ReparsePoint)
            {
                AddFileNamesToList(item, allFiles);
            }
        }

    }

您可以将Regex定义如下，并在代码中使用它。

 Regex rule = new Regex(@"(\\ |[^ ])+\$#x9\b");

可以将代码修改为

static void Main(string[] args)
{
    string sourceFolder = @"C:\dom\Xml";
    string searchWord = @"(\\ |[^ ])+\$#x9\b";
    Regex rule = new Regex(searchWord);

    List<string> allFiles = new List<string>();
    AddFileNamesToList(sourceFolder, allFiles);
    foreach (string fileName in allFiles)
    {
        string contents = File.ReadAllText(fileName);
        if (rule.IsMatch(contents))
        {
            Console.WriteLine(fileName);
        }
    }

    Console.WriteLine(" ");
    System.Console.ReadKey();
}
