  • Code SV, code consists of 4 including characters 2 the first character is the letter, 2 is the number of characters
  • Sv class is one of the values ​​cuat set of classes: CMPM1, CNPm2, CNPM3
  • Tong believes the book appear in order of code books, title, the XB, XB year

2. Drawing DOM model

3. Using both audiences XMLDOM browse the entire tree structure and display information secondary students 5 and information of the student loan pay

Chart DOM

In fact, you only need to turn on the internal structure of the tree is finished.

Browse and print out information on loan SV stuff 5

To browse and print out the information I need to use C #, Java, JavaScript, … Here, I use JavaScript.

<srcipt language = "JavaScript">
	function read(){
		var i, xmlDoc, QLMuonNode, ttSV, ttMuon, ttSach, output;
		xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
		xmlDoc.load("thuvien.xml");
		
		// lay thong tin sinh vien muon sach thu 5
		QLMuonNode = xmldoc.getElementsByTagName("QLMuon")[4];
		
		// lay toan bo cac node con cua SinhVien
		ttSV = QLMuonNode.firstChild.childNodes;
		
		for (i = 0; i < ttSV.length; i++){
			output += ttSV[i].nodeName + ":" + ttSV[i].nodeValue + <br/>
		}
		
		// lay toan bo cac node con cua Muon
		ttMuon = QLMuonNode.lastChild.childNodes;
		
		for (i = 1; i < ttMuon.length; i++){
			output += ttMuon[i].nodeName + ":" + ttMuon[i].nodeValue + <br/>
		}
		
		// lay toan bo cac node con cua Sach, Sach nam tai node[0] cua ttMuon
		ttSach = ttMuon[0].childNodes;
		
		for (i = 0; i < ttSach.length; i++){
			output += ttSach[i].nodeName + ":" + ttSach[i].nodeValue + <br/>
		}
		
		// hien thi thong tin
		document.write(output);
	}
