tag but when a div tag with style came it will not replace it i.e.

not getting replaced.

推荐答案

using System.Text.RegularExpressions;

[...]

[...]

private string ReplaceDivTagToBrakeTag(string data)
{
  Regex regEx = new Regex(@"<div.*>(.*)</div>");

  Match m = regEx.Match(data);

  return "<br>" + m.Groups[1].Value.Trim();
}

您需要单独处理(带有div的样式)........

You need to handle it (style with div) separately........

data.Replace("<div>", "<br>").Replace("</div>", String.Empty).Replace("<div style=any style>", "<br>").ToString();

所以也许您会将这些数据解析为XML.

这样，您就不必在每次数据更改时都进行更改.
我不确定xml解析器是否足以满足此要求.如果您的数据足够简单并且格式正确，我应该这样做.对于更复杂的情况，请使用非标准HTML解析器库之一( http://htmlagilitypack.codeplex.com/ [

So maybe you will parse this data as XML.

http://msdn.microsoft.com/en-us/library/cc189056%28v=vs.95%29.aspx

This way you will not have to change it everytime data will change.
I am not sure if xml parser will be sufficient for this. I should if your data will be simple enough and formatted correctly. For more complicated cases use one of non standard HTML parser libraries (http://htmlagilitypack.codeplex.com/[^] this looks promising).

As for parsing it with regex read:

http://www.codinghorror.com/blog/2009/11/parsing-html-the-cthulhu-way.html

I know that RegExp is simple, but you have problems already with this, and with RegExp and Html are always problems (been there, done that and it will not happen again).
