javascript 读取xml文件、读取节点数据的简单示例

读取的节点数据，还有一种情况是读取节点属性数据。 感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编来看看吧。经测试代码如下：

/**
 * 读取xml文件、读取节点数据
 *
 * @param 
 * @arrange (编程之家) jb51.cc
 **/
<script type=text/javascript>
var objLength = null;
var xmlHttp;
var strurl = ;
function ajaxrequst() {
if (window.ActiveXObject) {
xmlHttp = new ActiveXObject(Microsoft.XMLHTTP);
}
else {
xmlHttp = new XMLHttpRequest();
}
try {
strurl = /data/rdzz.xml;
xmlHttp.onreadystatechange = LoadXmlFile;
xmlHttp.open(GET,strurl + ?time= + (new Date()).getTime(),true);
xmlHttp.send(null);
}
catch (e) {
}
}

function LoadXmlFile() {
var content = ;
if (xmlHttp.readyState == 4) {
if (xmlHttp.status == 200) {
var xmlDOM = xmlHttp.responseXML;
var xmlRoot = xmlDOM.documentElement;
try {
var objLength = xmlRoot.getElementsByTagName(Item);

for (var i = 0; i < objLength.length; i++) {
var elementtitle = objLength[i].getElementsByTagName('NewsTitle')[0];
var elementtime = objLength[i].getElementsByTagName('NewsTime')[0];
var elementurl= objLength[i].getElementsByTagName('NewsUrl')[0];

// LastValue = objLength[i].getAttribute( LastValue )
// Prediction = objLength[i].getAttribute( Prediction )
// Actual = objLength[i].getAttribute( Actual )
// importance = objLength[i].getAttribute( importance )
// newstime = objLength[i].getAttribute( NewsTime )

var title = elementtitle.textContent || elementtitle.text;
var time = elementtime.textContent || elementtime.text;
var url = elementurl.textContent || elementurl.text;

content += <li><dl><dd> + time + </dd><dd><a href=' + url + ' target='blank'> + title + </a></dd></dl></li>;
}
document.getElementById(newsInfo).innerHTML = content;
}
catch (e) {
}
} 
}
}
</script>

经测试代码如下：

<input id=Button1 type=button value=read onclick=ajaxrequst() />
<div id=newsInfo></div>
