用ajax解析rss简单例子
<script language="javascript">
var bloglist=new Array();var xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
function startload(){
xmlHttp.open("GET","http://www.cnblogs.com/zwl12549/Rss.aspx",true);xmlHttp.onreadystatechange=function(){ if(xmlHttp.readystate==4 && xmlHttp.status==200){ var xmldom=xmlHttp.responseXML; var channel=xmldom.documentElement.childNodes.item(0); var itemlist=channel.childNodes; for(var i=0;i<itemlist.length;i++){ var node=itemlist.item(i); if(node.tagName=="title"){ blogtitle.innerHTML=node.text;
} if(node.tagName=="description"){ blogdescription.innerHTML=node.text; } if(node.tagName=="generator"){ bloggenerator.innerHTML=node.text; } if(node.tagName=="item"){ bloglist[bloglist.length]=node.childNodes; } } showitem(bloglist[0]); }}xmlHttp.send(null);}function showitem(itemlist){ for(var i=0;i<itemlist.length;i++){ var node=itemlist.item(i); if(node.tagName=="title"){ itemtitle.innerHTML=node.text; } if(node.tagName=="link"){ itemlink.href=node.text; } if(node.tagName=="description"){ description.innerHTML=node.text; } if(node.tagName=="author"){ author.innerHTML=node.text; } if(node.tagName=="pubDate"){ pubDate.innerHTML=node.text; } }
}
</script><body onload="startload()"><font color="blue"><a id="bloglink" href="#"><div id="blogtitle"></div></a></font><br />By <font color="blue"><div id="bloggenerator"></div></font><br /><font color="blur"><div id="blogdescription"></div></font><br /><br /><font color="#000066"><a id="itemlink" href="#"><div id="itemtitle"></div></a></font><br />By <font color="blue"><div id="author"></div></font><br /><div id="description"></div><br /><div id="pubDate" align="right"></div></body>
