=====对数据源做出相应的条件处理======
string all = sw.ToString();
Regex r = new Regex("<img.[^>]+[>]+", RegexOptions.ExplicitCapture);//通过正则去除数据源中‘ img ‘标签
string result1 = r.Replace(all, "");
Regex rr = new Regex(@"<a[^>]*>|</a>$");//通过正则去除数据源‘ a ‘标签并保留‘ a ‘标签的文本值
string result = rr.Replace(result1, "");
Response.Write(result);

测试导入的表图片如下：（截图只截取部分）
将Repeater控件导入Excel表（正则清除a标签保留文本，img标签清除）
