使用javascript访问xml中的属性

给定以下xml，如何访问节点中的记录属性，这是第二条记录

在我看来，最好使用jQueryAjax来实现这一点

在Jquery Ajax中，它将类似于以下内容：

$(document).ready(function(){
$.ajax({
    type: "GET",
    url: "../xml/yourxmlfile.xml", 
    dataType: "xml",
    success: function(xml) 
    {
        $(xml).find('nodename').each(function()
        {
            var attrvalue = $(this).attr('attributename');
            ...
            do what you want here
        }
    }
});
});

如果您想坚持使用纯javascript，可能需要使用正则表达式

希望这对您有所帮助
如果您没有jQuery和/或没有通过受控的AJAX调用检索它，那么您可以使用：

var el = document.createElement("xml");
el.innerHTML = docData;  //xml content
var record = el.getElementsByTagName("d:Table1")[0];
var recor_builders_name = record.attributes["builders_name"].value;
document.write(recor_builders_name); //Do what you need with your record

现在，如果使用ajax调用，但不使用jQuery，则可以使用调用中的responseXML属性。该元素已经是一个文档对象，因此您可以跳过前两行，改为设置
el=yourAjax.responseXML
（或者直接使用该属性，如果您愿意的话）

顺便说一句，我假设xml是一个更大文档的片段，缺少根节点close标记只是一个复制粘贴错误
