Doesnt attribute nodes count as children in DOM2?
Doesnt attribute nodes count as children in DOM?
My page here is like this 5 children in the body: text > h1 > text > div > text > //end of 5 children But doesnt the attributnodes count? Shouldnt the childNodes property return an array of all types of nodes? With text > attribute > text > h1 > attribut > text > div > attribut > text > p //etc...
I have this page:

with this script:
function domTest() {
var le = document.body.childNodes.length;
alert(le);//alerts 5 children where are attribut no开发者_运维百科des?
for(i = 0; i < le; i++) {
alert(document.body.childNodes[i].nodeType);
alert(document.body.childNodes[i].nodeName);
alert(document.body.childNodes[i].nodeValue);
}
}
window.onload = domTest;
Attr objects inherit the Node interface, but since they are not actually child nodes of the element they describe, the DOM does not consider them part of the document tree. Thus, the Node attributes parentNode, previousSibling, and nextSibling have a null value for Attr objects
From the Attr interface description of DOM Level 2 Core.
