js 替换字符串指定一段字符的内容
var string=" <strong>张三：<span id=1>123</span></strong> <strong>李四：<span id=2>456</span></strong> <strong>小明：<span id=3>789</span></strong> ";
我想把“<strong>张三：<span id=1>123</span></strong>” 里的“123”字符替换成“xxx”（但字符“123”是随机的，不能确定）
要怎样才能实现呢？感激各位！

var str2 = string.replace(/>\d+</g,">xxx<");
alert(str2);

看是不是这样的。
