初学javascript，学习中用到在IE中建立XML对象，于是写了一个简单的“库”。因为水平所限，肯定会有不恰当的地方，欢迎指正。
如果大家有知道现存的更好的东西，非常希望大家能将它推荐给我。

function
onXml() { var
oXmlOp = new
XmlObject(); var
oTop = oXmlOp; var
oTop = oXmlOp.AddAttrTextNode(oXmlOp.getXmlObj(), "UserInfo", "", "class", "dianxin1005"); oXmlOp.AddAttrTextNode(oTop, "Subject", "Chinese", "Score", "98"); oXmlOp.AddAttrTextNode(oTop, "Subject", "Math", "Score", "77"); oXmlOp.AddAttrTextNode(oTop, "Subject", "English", "Score", "99"); alert(oXmlOp.getXmlStr());} |
生成的XML是：
<UserInfo class="dianxin1005">
<Subject Score="98">
Chinese
</Subject>
<Subject Score="77">
Math
</Subject>
<Subject Score="99">
English
</Subject>
</UserInfo>
