Mivuno
Mfano 1
Mashusho hii yaandiko yana kuwakilika "books.xml" kwenye xmlDoc, na kuzafanya mjea (<edition>) na kuiongeza kwenye kina kidogo cha mjea kuu ya <book>:
var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { myFunction(this); } }; xhttp.open("GET", "books.xml", true); xhttp.send(); function myFunction(xml) { var xmlDoc = xml.responseXML; var newel = xmlDoc.createElement("edition"); var x = xmlDoc.getElementsByTagName("book")[0]; x.appendChild(newel); document.getElementById("demo").innerHTML = x.getElementsByTagName("edition")[0].nodeName; }
Mfano 2
mashindano hii inaingia "books.xml" katika xmlDoc na inapiga maelezo mpya kwa kila kitu <book>:
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, y, z, i, newel, newtext, xmlDoc, txt; xmlDoc = xml.responseXML; txt = ""; x = xmlDoc.getElementsByTagName("book"); for (i = 0; i < x.length; i++) { newel = xmlDoc.createElement("edition"); newtext = xmlDoc.createTextNode("first"); newel.appendChild(newtext); x[i].appendChild(newel); } // kuja kila title na edition y = xmlDoc.getElementsByTagName("title"); z = xmlDoc.getElementsByTagName("edition"); for (i = 0; i < y.length; i++) { txt += y[i].childNodes[0].nodeValue + " - Edition: " + z[i].childNodes[0].nodeValue + "<br>"; } document.getElementById("demo").innerHTML = txt; }
