近日在项目中需要将一个带有超链接的页面导出成Excel，但是导出的文件中要去除这些超链接。
页面主体部分是一个<table>标签，是后台生成的。
我的解决方法如下：
1.取到table 的InnerHtml；
2.将取到的InnerHtml中的超链接全部替换掉；
3.将新的字符串拼接成一个可导出的HTML页，并导出。
第一步就不废话了。
第二步，取到InnerHtml的内容，将其中的超链接替换成空字符。因为要保留带超链接的文本本身，所以这里分两步
1.利用正则表达式替换掉超链接文本前面的超链接部分
2.利用String.Replace替换掉</a>

1 string result = Regex.Replace(resultHtml, "<a[^>]*>", ""); 2 result = result.Replace("</a>", "");
第三步，拼接HTML页，导出。
原HTML页如下：

拼接可导出的HTML页，并导出（本段代码转自http://kb.cnblogs.com/a/1339957/）
