msdn关于xml element
w3schools中关于xml island
但对于不规则的xml文件，我死活找不到使用数据岛的方法。好像xml island把xml当成一个类似数据库的表，直接把根目录下的元素当成recordset。所以对于xml文件如下找不到解决的办法：
<?
xml version="1.0" encoding="gb2312"
?>
<!--
file name = rss_down_s10.xml
-->
<
rss
version
="2.0"

为了获取前10条item的数据，只好土炮制造javascript如下
DOCTYPE HTML PUBLIC
"

"

<
HTML

<
HEAD
>
<
TITLE

Test
SPAN style="COLOR: #000000">TITLE

function
load()
{
var
xmlDoc
=
new
ActiveXObject(
"
Microsoft.XMLDOM
"
);
xmlDoc.load(
"
rss_Down_s10.xml
"
);
var
channelNode
=
xmlDoc.documentElement.firstChild;
var
objNodeList
=
channelNode.selectNodes(
"
//item
"
);
 
for
(
var
count
=
0
;count
<
10
&&
count
<=
objNodeList.length;count
++
)
{
var
itemnode
=
objNodeList.item(count);
var
titleText
=
""
;
var
titleNode
=
itemnode.selectSingleNode(
"

);
if
(titleNode
!=
null
)
titleText
=
titleNode.text;
var
linkText
=
""
;
var
linkNode
=
itemnode.selectSingleNode(
"
link
"
);
if
(linkNode
!=
null
)
linkText
=
linkNode.text;
addRow(
"
test
"
,count,titleText,linkText);
 }
 }
function
addRow(id,index,title,link)
{
var
tbody
=
document.getElementById(id).getElementsByTagName(

var
row
=
document.createElement(

var

td0.appendChild (document.createTextNode(index))
var

如果rss_Down_s10.xml可以被修改，还可以使用xsl来按格式显示数据。
