XML+DOM将元素的数据依次插入到表格中

下面写的是主要的程序部分，不能清除原来的数据

var dtable = document.getElementById("dataBody");

var teamEls = xmlHttp.responseXML.getElementsByTagName("team");

for(var i=0;i<teamEls.length;i++) {

var elTr = dtable.insertRow(i);

var teamEl = teamEls.item(i);

var elId = teamEl.getElementsByTagName("id");

var id = elId.item(0).firstChild.nodeValue;

var elTdId = elTr.insertCell(0);

elTdId.innerHTML = id;

var elName = teamEl.getElementsByTagName("name");

var name = elName.item(0).firstChild.nodeValue;

var elTdName = elTr.insertCell(1);

elTdName.innerHTML = name;

var elSlogan = teamEl.getElementsByTagName("slogan");

var slogan = elSlogan.item(0).firstChild.nodeValue;

var elTdSlogan = elTr.insertCell(2);

elTdSlogan.innerHTML = slogan;

var elleader = teamEl.getElementsByTagName("leader");

var leader = elleader.item(0).firstChild.nodeValue;

var elTdleader = elTr.insertCell(3);

elTdleader.innerHTML = leader;

}
