皇帝讽刺剧

所以我想做的是获取XML文档中Title标记的变量“Name”的值，并将其显示在HTML站点上。现在代码可以很好地显示所有标记的值，但我不知道如何让它显示变量。

试试这个-

x=xmlDoc.getElementsByTagName('TITLE');
for (i=0;i<x.length;i++)
{
  alert(x[i].getAttribute('Name'));

document.write(x[i].getAttribute('Name'));
document.write("<br>");
}

x=xmlDoc.getElementsByTagName（'TITLE'）；
对于（i=0；i
x=xmlDoc.getElementsByTagName('TITLE');
for (i=0;i<x.length;i++)
{
  alert(x[i].getAttribute('Name'));

document.write(x[i].getAttribute('Name'));
document.write("<br>");
}
