我的 parsexml 代码:
var parseXml = function (xml) {
var dom = null;
if (window.DOMParser) {
try {
dom = (new DOMParser()).parseFromString(xml, "text/xml");
}
catch (e) { dom = null; }
}
else if (window.ActiveXObject) {
try {
dom = new ActiveXObject('Microsoft.XMLDOM');
dom.async = false;
if (!dom.loadXML(xml)) // parse error ..
window.alert(dom.parseError.reason + dom.parseError.srcText);
}
catch (e) { dom = null; }
}
else
alert("cannot parse xml string!");
return dom;
}
现在假设
s="<a>random</a>";
b=parseXml(s);
现在我想s
从b
. 我怎么做?
