我想取出红色的内容外层标签用flash播放器替代。蓝色内容不固定。
逻辑不是很会。C#正则

Answer 1

外层标签指哪些内容，不是<embed>包含的内容吗， 如果是，就取以<embed开头，以>结尾

Answer 2

是想根据src找到该标签吗？
string tempStr = File.ReadAllText(@"C:\Users\myx\Desktop\Test.txt", Encoding.GetEncoding("GB2312"));//读取txt                string src="/editor/kindeditor/attached/media/20130626/20130626065054_3546.avi";
                string pattern = @"(?i)<embed[^>]*?src=(['""]?)"+src+@"\1[^>]*?>";
                tempStr = Regex.Replace(tempStr,pattern,"替换内容");

Answer 3

string regex = @"(?i)<embed[^>]*src=['""]?([^'""]+)\1[^/>]*?>",
       flashMask = "<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" codebase=\"...\"><param name="movie" value=\"$1\" /><param name=\"quality\" value=\"high\"/></object>";
tempStr = Regex.Replace(html, regex, flashMask);

Answer 4

string regex = @"(?i)<embed\b[^>]*?src=(['""]?)([^'""]+)\1[^>]*?autostart=\1(?:true|false)\1[^>]*?>",
       flashMask = "<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" codebase=\"...\"><param name="movie" value=\"$2\" /><param name=\"quality\" value=\"high\"/></object>";
result= Regex.Replace(html, regex, flashMask);

Answer 5

取出embed 标签里的src然后把embed 标签替换成flash播放标签，将获取的src添加到flash标签的src里。能获取到宽高在调整flash宽高最好，不能调整也行。

Answer 6

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="722" height="551" id="FLVPlayer">

  <param name="salign" value="lt" />
  <param name="quality" value="high" />
  <param name="scale" value="noscale" />
  <param name="FlashVars" value="&MM_ComponentVersion=1&skinName=Halo_Skin_3&streamName=7&autoPlay=true&autoRewind=false" />
  <embed src="替换掉的src" flashvars="&MM_ComponentVersion=1&skinName=Halo_Skin_3&streamName=7&autoPlay=true&autoRewind=false" quality="high" scale="noscale" width="722" height="551" name="FLVPlayer" salign="LT" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>

Answer 7

string tempStr = File.ReadAllText(@"C:\Users\myx\Desktop\Test.txt", Encoding.GetEncoding("GB2312"));//读取txt                
                string pattern = @"(?i)<embed[^>]*?src=(['""]?)([^'""]*?)\1[^>]*?>";
                tempStr = Regex.Replace(tempStr, pattern, a => {
                    string src = a.Groups[2].Value;
                    string result = string.Empty+src;//根据src拼接结果
                    return result;
                });

Answer 8

  string html = @"<p>
