怎样从html代码中提取出控件
比如: <p> <input type= "checkbox " checked= "checked " name= "name " value= "hhh " /> fasfdsafsdaf <input maxlength= "50 " size= "4 " name= "name " /> </p> ,中提出 " <input type= "checkbox " checked= "checked " name= "name " value= "hhh " /> "这样的控件,并用1等数字来替换,控件可能是其他类型的,谢谢指教!最好是C#的,javascript也行.
------解决方案--------------------
用下面的代码试下
string yourStr = richTextBox1.Text;
MatchCollection mc = Regex.Matches(yourStr, @ " <(input|select)\s[^> ]*?> ([\s\S*]*? </\1> )? ", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups[0].Value + "\n\n\n "; //提取结果
}
别的方法我不会，只会用正则，只要楼主的需求明确，应该还是可以满足楼主的要求的，只不过可能并不是最佳的处理方式吧

<body>
<div id= "s "> </div>
<form>
<input type= "text " name= "s1 "/>
<input type= "text " name= "s1 "/>
<input type= "text " name= "s1 "/>
<input type= "text " name= "s1 "/>
<input type= "text " name= "s1 "/>
<select name= "s "/>
</form>
<script>
k(document.body);
function k(obj){
for (var i = 0; i < obj.childNodes.length; i++){
if (obj.childNodes[i].hasChildNodes()) {
k(obj.childNodes[i]);
}
var tn = obj.childNodes[i].nodeName.toLowerCase();
if (tn == "input " || tn == "select " || tn == "textarea "){
document.getElementById( "s ").innerHTML += tn + ": name: " + obj.childNodes[i].getAttribute( "name ") + " <br /> "
}
}
}
</script>
</body>
