XML DOM - Clone Node
XML DOM - Clone Node
在本章中,我们将在XML DOM物体上放弃Clone Node的运行。 衣帽子操作被用来制作特定噪音的复制件。
cloneNode()
这种方法回收了这一节点的重复,即作为节点的通用复印件。 重复点子没有母子(母子网无效),也没有用户数据。
Syntax
The cloneNode( methods has the following syntax -
Node cloneNode(boolean deep)
这种方法回收了重复点。
Example
The following example (clonenode_example.htm) parses an XML document () into an XML DOM Object and makes a deep拷贝 of the first Employee i> i.
<!DOCTYPE html>
<html>
<head>
<script>
function loadXMLDoc(filename) {
if (window.XMLHttpRequest) {
xhttp = new XMLHttpRequest();
} else // code for IE5 and IE6 {
xhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",filename,false);
xhttp.send();
return xhttp.responseXML;
}
</script>
</head>
<body>
<script>
xmlDoc = loadXMLDoc("/dom/node.xml");
x = xmlDoc.getElementsByTagName( Employee )[0];
clone_node = x.cloneNode(true);
xmlDoc.documentElement.appendChild(clone_node);
firstname = xmlDoc.getElementsByTagName("FirstName");
lastname = xmlDoc.getElementsByTagName("LastName");
contact = xmlDoc.getElementsByTagName("ContactNo");
email = xmlDoc.getElementsByTagName("Email");
for (i = 0;i < firstname.length;i++) {
document.write(firstname[i].childNodes[0].nodeValue+
+lastname[i].childNodes[0].nodeValue+ ,
+contact[i].childNodes[0].nodeValue+ , +email[i].childNodes[0].nodeValue);
document.write("<br>");
}
</script>
</body>
</html>
如你在上述例子中可以看到,我们制定了cloneNode( param to true。 因此,在Employe的元素下,每个儿童部分均被复制或掩饰。
Execution
将这一档案作为服务器线路上的clonenode_example.htm(该文档和de.xml在服务器上应当走同样的道路)。 我们将获得以下产出:
Tanmay Patil, 1234567890, tanmaypatil@xyz.com Taniya Mishra, 1234667898, taniyamishra@xyz.com Tanisha Sharma, 1234562350, tanishasharma@xyz.com Tanmay Patil, 1234567890, tanmaypatil@xyz.com
您将注意到第一个Employee元素被完全掩饰。
