示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并获取 "books.xml" 中第一个<title>元素中的属性数:
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
<script>
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x = xmlDoc.getElementsByTagName("book")[0].attributes;
document.getElementById("demo").innerHTML =
x.length;
}
</script>
</body>
</html>
尝试一下
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并在第一个<book>元素中获取 "category" 属性的值:
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
<script>
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var x, i, xmlDoc, txt;
xmlDoc = xml.responseXML;
txt = "";
x = xmlDoc.getElementsByTagName('book');
for (i = 0; i < x.length; i++) {
txt += x.item(i).attributes.getNamedItem("category").value + "<br>";
}
document.getElementById("demo").innerHTML = txt;
}
</script>
</body>
</html>
