这篇文章主要介绍了用javascript读取xml文件读取节点数据的具体实现,需要的朋友可以参考下
下面代码是读取的节点数据，还有一种情况是读取节点属性数据。
<head> <title></title> <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> </head> <body> <input type="button" value="read" /> <div></div> </body>
