<body>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script>
$(function(){
var xmlDom=$($.parseXml("<?xml version=\"1.0\" encoding=\"utf-8\" ?><root><person></person></root>"));
xmlDom.find("root").appendXml("<content/>").text("测试");
xmlDom.find("content").beforeXml("<test/>");
alert(xmlDom.xml());
});
(function($) {
function mnpXml(opCode, xmlStr) {
return this.each(function() {
if (typeof xmlStr != "string") return;
if (!jQuery.isXMLDoc(this)) return;
var node = $.parseXml(xmlStr).firstChild.cloneNode(true);
switch (opCode) {
case "append":
this.appendChild(node);
break;
case "prepend":
if (this.childNodes.length > 0)
this.insertBefore(node, this.firstChild);
else
this.appendChild(node);
break;
case "after":
if (this.nextSibling)
this.parentNode.insertBefore(node, this.nextSibling);
else
this.parentNode.appendChild(node);
break;
case "before":
this.parentNode.insertBefore(node, this);
break;
}
});
}
$.fn.extend({
appendXml: function(s) {
return mnpXml.call(this, "append", s);
},
prependXml: function(s) {
return mnpXml.call(this, "prepend", s);
},
afterXml: function(s) {
return mnpXml.call(this, "after", s);
},
beforeXml: function(s) {
return mnpXml.call(this, "before", s);
},
xml: function() {
var elem = this[0];
return elem.xml || (new XMLSerializer()).serializeToString(elem) ;
},
innerXml: function() {
var s = this.xml();
var i = s.indexOf(">"), j = s.lastIndexOf("<");
if (j > i)
return s.substring(i + 1, j);
else
return "";
}
});
$.extend(jQuery, {
parseXml: function(xmlStr) {
if (window.ActiveXObject) {
var xd = new ActiveXObject("Microsoft.XMLDOM");
xd.async = false;
xd.loadXML(xmlStr);
return xd;
}
else if (typeof DOMParser != "undefined") {
var xd = new DOMParser().parseFromString(xmlStr, "text/xml");
return xd;
}
else return null;
},
toXml: function(obj, nodeName, useAttr) {
var x = $($.parseXml("<" + nodeName + " />"));
var n = x.find(":first");
for (var p in obj) {
if (useAttr)
n.attr(p, obj[p]);
else
n.appendXml("<" + p + " />").find(p).text(obj[p]);
}
return x[0];
}
});
})(jQuery);
</script>
</body>
</html>
运行结果：
