XML实现文字转换

下面为效果显示

xml文件：ticker20021106.xml

脚本说明:
把如下代码加入<body>区域中

//Container for ticker. Modify its STYLE attribute to customize style:
var tickercontainer='<div id="container" style="background-color:#FFFFE1;width:150;height:120;font:normal 13px Verdana;"></div>'

//Specify path to xml file
var xmlsource="ticker20021106.xml"

////No need to edit beyond here////////////
//load xml file
if (window.ActiveXObject)
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
else if (document.implementation && document.implementation.createDocument)
var xmlDoc= document.implementation.createDocument("","doc",null);
if (typeof xmlDoc!="undefined"){
document.write(tickercontainer)
xmlDoc.load(xmlsource)
}

//Regular expression used to match any non-whitespace character
var notWhitespace = /\S/

function init_ticker(){
//Cache "messages" element of xml file
tickerobj=xmlDoc.getElementsByTagName("xmlticker")[0]

//REMOVE white spaces in XML file. Intended mainly for NS6/Mozilla
for (i=0;i<tickerobj.childNodes.length;i++){
if ((tickerobj.childNodes[i].nodeType == 3)&&(!notWhitespace.test(tickerobj.childNodes[i].nodeValue))) {
tickerobj.removeChild(tickerobj.childNodes[i])
i--
}
}
document.getElementById("container").innerHTML=tickerobj.childNodes[1].firstChild.nodeValue
msglength=tickerobj.childNodes.length
currentmsg=2
themessage=''
setInterval("rotatemsg()",tickerobj.childNodes[0].firstChild.nodeValue)
}

function rotatemsg(){
var msgsobj=tickerobj.childNodes[currentmsg]
if (msgsobj.getAttribute("url")!=null){
themessage='<a href="'+msgsobj.getAttribute("url")+'"'
if (msgsobj.getAttribute("target")!=null)
themessage+=' target="'+msgsobj.getAttribute("target")+'"'
themessage+='>'
}

if (msgsobj.getAttribute("url")!=null)
themessage+='</a>'

//Rotate msg and display it in DIV:
document.getElementById("container").innerHTML=themessage
currentmsg=(currentmsg<msglength-1)? currentmsg+1 : 1
themessage=''
}

function fetchxml(){
if (xmlDoc.readyState==4)
init_ticker()
else
setTimeout("fetchxml()",10)
}
