我有以前的XML文件,我想用Javascript解析它,如何访问特定类型的所有子类型?
我用过
var x=xmlhttp.responseXML.documentElement.getElementsByTagName("Type");
解析Types,但是我如何解析每种类型的Subtypes?
答案 0 :(得分:1)
var x=xmlhttp.responseXML.documentElement.getElementsByTagName("Type");
for (var i = 0; i < x.length; i++) {
var subTypes = new Array();
var y = x[i].getElementsByTagName("SubTypes")
for (var j = 0; j < y.length; j++){
subTypes.push(y[j])
// or you could just process them here
}
// process the subtypes in this type
}
那应该让你到那里......尽管

您也可以使用xpath:
var x = xmlhttp.responseXML;
var subtypes = x.evaluate( '//Types/Type/SubType', x.documentElement);
