</script></td> 

输出是这样的

<script type="text/javascript">
same above script plus following Line
</script><a href="mailto:[email protected]">[email protected]</a></td>

我编写了自己的自定义解析器，它将读取脚本并从中解析电子邮件。代码如下

如果可以优化此代码或可以编写得更简洁，请告诉我

private string ReadEmail(string EmailScript)
{
  string EncriptedEmail = "";
  string dataPart = "";
  dataPart = EmailScript.Substring(0, EmailScript.IndexOf("document.write")).Replace("//<![CDATA[\r", "").Replace("\"", "").Replace("\r\n","");
  EncriptedEmail = EmailScript.Replace("\"","");
  EncriptedEmail = EncriptedEmail.Substring(EncriptedEmail.IndexOf("'> + "), EncriptedEmail.IndexOf(" + </a>") - EncriptedEmail.IndexOf("'> +")).Replace("'> +", "").Trim();
  string[] requiredVariables = EncriptedEmail.Split('+');
  List<string> ExtractedDataFromRaw = new List<string>();
  string email = "";
  foreach (string variable in requiredVariables)
  {
    string temp = dataPart.Substring(dataPart.IndexOf(variable),dataPart.Length-dataPart.IndexOf(variable)).Replace(" ","");
    string tempValueofVariable = temp.Substring(0, temp.IndexOf(";"));
    tempValueofVariable = tempValueofVariable.Substring(tempValueofVariable.IndexOf("="), tempValueofVariable.Length - temp.IndexOf("=")).Replace("=","");
    if (tempValueofVariable.Contains("String.fromCharCode"))
    {
      tempValueofVariable = GetCharacterFromASCII(tempValueofVariable.Replace("String.fromCharCode(", "").Replace(")", ""));
    }
    ExtractedDataFromRaw.Add(tempValueofVariable.Replace("'",""));
    email += tempValueofVariable.Replace("'", "");
    }
    return email;
 }
 private string GetCharacterFromASCII(string value)
 {
    int result = 0;
    int.TryParse(value, out result);
    return char.ConvertFromUtf32(result);
 }

Answer 2

该代码从字符代码点一次构建一个字符的电子邮件地址，然后再进行组装。我想这是为了防止垃圾邮件。根据您需要执行的操作，最简单的方法可能是使用 jQuery 等从链接中提取电子邮件地址。 $('a[href^=mailto]').attr('href').substring(7) 或其他东西应该可以做到这一点。
