This example only works in browsers that support DOM ranges.
This example will fail in Internet Explorer.
DOM Range Example
function extractContent() {
var oP1 = document.getElementById("p1");
var oHello = oP1.firstChild.firstChild;
var oWorld = oP1.lastChild;
var oRange = document.createRange();
oRange.setStart(oHello, 2);
oRange.setEnd(oWorld, 3);
var oFragment = oRange.extractContents();
document.body.appendChild(oFragment);
}
Hello World
