＊＊＊＊＊＊＊高分求正则表达式

[OceanRain]

用正则取两则之间的数字?(c#和javascript两种方式)
d0s0s3t1p0to99999i3m0to99999c50m1rp1.htm
如有一个函数 string[] test(string start, string end)
调用时:test("s","s") 返回0,3
test("p","to") 返回0,99999
test("m","to") 返回0,99999

没看明白要干嘛

[路人乙e]

string s = "d0s0s3t1p0to99999i3m0to99999c50m1rp1.htm";
public string[] GetString(string s1, string s2)
{
Regex reg = new Regex(String.Format("{0}([\d]+){1}([\d]+)", s1, s2));
Match mat = reg.Match(s);
if(mat.Success) return new string[]{ mat.Groups[1].Value, mat.Groups[2].Value };
else return null;
}

楼上正解

[OceanRain]

觉得这种方式用正则实现比较好

S1, S2不能直接带入，有时需要转义，如.?{}[]等等。

        private void GetDigit(string input, string start, string end, out int startDigit, out int endDigit)
        {
            Regex reg = new Regex(string.Format("{0}(?<StartDigit>[\\d]+).*{1}(?<EndDigit>[\\d]+)",start,end));
            Match m = reg.Match(input);
            startDigit = endDigit = int.MinValue;
            if(m.Success && m.Groups.Count >=3)
            {
                int.TryParse(m.Groups["StartDigit"].Value,out startDigit);
                int.TryParse(m.Groups["EndDigit"].Value,out endDigit);
            }
            Console.WriteLine(string.Format("start digit:{0},end digit:{1}", startDigit, endDigit));
        }


   string str = "d0s0s3t1p0to99999i3m0to99999c50m1rp1.htm";
   int startDigit,endDigit;

   GetDigit(str,"d","s",out startDigit,out endDigit);
   GetDigit(str,"p","to",out startDigit,out endDigit);
   GetDigit(str,"c","m",out startDigit,out endDigit);

   /*输出

  start digit:0,end digit:3
  start digit:0,end digit:99999
  start digit:50,end digit:1

    */

C#中提供了方法可以对传入的变量做转义处理，以避免输入类似于“abc(def”这样的字符串时导致程序抛异常

private string[] test(string src, string start, string end)
{
    Regex reg = new Regex(string.Format("{0}(\\d+){1}(\\d+)", Regex.Escape(start), Regex.Escape(end)));
    Match m = reg.Match(src);
    if (m.Success)
    {
        return new string[]{m.Groups[1].Value, m.Groups[2].Value};
    }
    else
        return null;
}
//调用
string str = "d0s0s3t1p0to99999i3m0to99999c50m1rp1.htm";
string[] result = test(str, textBox1.Text, textBox2.Text);
if (result != null)
    richTextBox2.Text += result[0] + "\n" + result[1];

javascript中MS就没有这样的函数了

<script type="text/javascript">
    document.close();
    document.open();

    var str= "d0s0s3t1p0to99999i3m0to99999c50m1rp1.htm";
    var result = test(str, "to", "i");
    for(var i=1; i<result.length; i++)
    {
        document.write(result[i]);
        document.write("<br>");
    }

    function test(src, start, end)
    {
        var re = new RegExp(start + "(\\d+)" + end + "(\\d+)", "i");
        return src.match(re);
    }
</script>
