我有一个XML文件，我想使用JavaScript从中提取一些属性，但我只希望它返回来自父节点的属性与我在以前的脚本中作为HTML页面的一部分设置的全局变量匹配时出现的属性

下面是我的XML文件

<?xml version="1.0" encoding="UTF-8"?>
<directory name="weeks">
<directory name="week42">
<file name="one.pdf"/>
<file name="two.pdf"/>
<file name="three.pdf"/>
</directory>
<directory name="week43">
<file name="four.pdf"/>
<file name="five.pdf"/>
</directory>
</directory>

非常感谢您的建议。谢谢梯子

我们开始

    <!DOCTYPE html>
<html>
<body>
    <script>
        text = "<directory name='weeks'><directory name='week42'>";
        text = text + "<file name='one.pdf'/><file name='two.pdf'/>";
        text = text + "<file name='three.pdf'/></directory>";
        text = text + "<directory name='week43'><file name='four.pdf'/>";
        text = text + "<file name='five.pdf'/></directory></directory>";
        if (window.DOMParser) {
            parser = new DOMParser();
            xmlDoc = parser.parseFromString(text, "text/xml");
        } else // Internet Explorer
        {
            xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = false;
            xmlDoc.loadXML(text);
        }
        var x = xmlDoc.getElementsByTagName('directory');

        var constant = 'week43';
        for (var i =0; i < x.length; i++) {
            var attrs = x[i].attributes;
            var k = attrs.getNamedItem("name").nodeValue;
            if (constant == k) {
                if (x[i].childNodes) {
                    document.write(k);
                    for ( var j = 0; j < x[i].childNodes.length; j++) {
                        var detail = x[i].childNodes[j];
                        var lattr = detail.attributes.getNamedItem("name").nodeValue;
                        document.write("<br>");
                        document.write(lattr);
                    }
                }
            }

        }


    </script>
</body>
</html>


text=“”；
text=text+“”；
text=text+“”；
text=text+“”；
text=text+“”；
if（window.DOMParser）{
parser=新的DOMParser（）；
xmlDoc=parser.parseFromString（text，“text/xml”）；
}else//internetexplorer
{
xmlDoc=新的ActiveXObject（“Microsoft.XMLDOM”）；
xmlDoc.async=false；
loadXML（文本）；
}
var x=xmlDoc.getElementsByTagName（'directory'）；
var常量=‘week43’；
对于（变量i=0；i”）；
文件编写（lattr）；
}
}
}
}

输出将是

for (i=0;i<x.length;i++)
