慕白兄：如何用以上正则式，只改变 <table ..到../table> 这段代码为一行，而不影响table外部的其他代码?
-----------------------------------------------
你的 <table> 外面还有代码吗???/
[解决办法]
不好意思上面的有点错误应该这样

Regex.Replace( "你的源代码 ",@ "(\r|(? <=> [^ <]*?)\s*(?=[^ <> ]*? <)) ", " ", RegexOptions.Compiled);

－－－－－－－
以前正则用得太多，中毒太深^o^,现在尝试转换思路，忘掉正则，正则只答理论，不给实现了

只改变 <table ..到../table> 这段代码为一行，而不影响table外部的其他代码
－－－－－－－
这种是典型的用正则委托来实现的需求，匹配出 <table ..到../table> 的内容，然后用委托进行替换
