如何在div <{1}} html中查找所选文字

例如,我们在本文中选择了5到11:

     <div id="txt" >This is some <i> text </i> </div>

已选中:is some

但在html中是:id="txt

如何查找并在<p><span>之间替换其他标签以避免丢失?

请原谅我糟糕的英语:)

演示:http://jsfiddle.net/dKaJ3/2/

function getSelectionHtml() {
    var html = "";
    if (typeof window.getSelection != "undefined") {
        var sel = window.getSelection();
        if (sel.rangeCount) {
            var container = document.createElement("div");
            for (var i = 0, len = sel.rangeCount; i < len; ++i) {
                container.appendChild(sel.getRangeAt(i).cloneContents());
            }
            html = container.innerHTML;
        }
    } else if (typeof document.selection != "undefined") {
        if (document.selection.type == "Text") {
            html = document.selection.createRange().htmlText;
        }
    }
    alert(html);
}
