    XML Parsing in s40 web apps?

    Hi,

    I was trying to parse an xml file in Web apps. USing DOM parser it is working fine on wrt, but it is not working on s40 web apps.

    I response is received when xhr.responseText is used. But xhr.responseXML is not responding anything (ie, null)

    I also tried XML tag reading using xhr.responseXML.getElementsByTagName("companyName"); in s40 web apps, but not responding (ie, null).

    Is there any solution ? Is there any other effective XML parser available for S40 Web apps.

    code snippets are

    function init()
    {

    getRSS(url);

    }




    function getRSS()
    {
    var xhr;
    rssfeed = url;

    //call the right constructor for the browser being used
    if (window.ActiveXObject)
    xhr = new ActiveXObject("Microsoft.XMLHTTP");
    else
    if (window.XMLHttpRequest) {
    xhr = new XMLHttpRequest();

    }
    else
    alert("AJAX request not supported");

    //prepare the xmlhttprequest object
    xhr.open("GET", rssfeed, true);
    xhr.setRequestHeader("Cache-Control", "no-cache");
    xhr.setRequestHeader("Pragma", "no-cache");
    xhr.onreadystatechange = function(){

    if (xhr.readyState == 4) {
    if (xhr.status == 200) {

    if (xhr.responseText != null) {

    var company = xhr.responseXML.getElementsByTagName("companyName");

    alert("name1::"+company[0].childNodes[0].nodeValue);

    }
    else {


    //return false;
    }
    }
    else {


    }
    }
    }


    //send the request
    xhr.send(null);

    }

    Hi,

    I hope that you got this working already. I have completely missed this thread previously, sorry for that.
    Basically the script you have should work. Only changes needed is to check for responseXML instead of responseText and remove alert(). Alert() does not work in Series 40 web apps.

    If you are generating the xml by yourself in your server, check that you set proper content type:
    header("Content-type: text/xml"); (PHP way)

    Br,

    Re: XML Parsing in s40 web apps?

    you can use it for parsing xml for s40 :

    Code:
    $(document).ready(function () {
        jQuery.support.cors = true;
    	   $.ajaxSetup({
    			error:function(x,e){
    				if(x.status==0){
    				alert('You are offline!!\n Please Check Your Network.');
    				window.location = 'index.html';
    				}else if(x.status==404){
    				alert('Requested URL not found.');
    				window.location = 'index.html';
    				}else if(x.status==500){
    				alert('Internel Server Error.');
    				window.location = 'index.html';
    				}else if(e=='parsererror'){
    				alert('Error.\nParsing JSON Request failed.');
    				window.location = 'index.html';
    				}else if(e=='timeout'){
    				alert('Request Time out.');
    				window.location = 'index.html';
    				}else {
    				alert('Unknow Error.\n'+x.responseText);
    				window.location = 'index.html';
    				}
    			}
    		});
        $.ajax({
            type: "GET",
            url: "http://data.bmkg.go.id/lastgempadirasakan.xml",
            crossDomain: true,
            dataType: "xml",
            success: xmlParser
        });
    });
    function xmlParser(xml) {
        $('#load').fadeOut();
    
     	$(xml).find("Gempa").each(function () {
            $(".main").append('<center><b>Terjadi Gempa Dirasakan ' + $(this).find("Magnitude").text() + ' </b></center><br>Tanggal : ' + $(this).find("Tanggal").text() + ' <br> Waktu : ' + $(this).find("Jam").text() + '<br>' + $(this).find("Keterangan").text() + ', dirasakan di ' + $(this).find("Dirasakan").text() + '');
            $(".bmkg").fadeIn(1000);
    	});
    }
    Replace xml url : http://data.bmkg.go.id/lastgempadirasakan.xml with your xml. And note the structure of the xml.
    Edit this part :
    Code:
    function xmlParser(xml) {
        $('#load').fadeOut();
    
     	$(xml).find("Gempa").each(function () {
            $(".main").append('<center><b>Terjadi Gempa Dirasakan ' + $(this).find("Magnitude").text() + ' </b></center><br>Tanggal : ' + $(this).find("Tanggal").text() + ' <br> Waktu : ' + $(this).find("Jam").text() + '<br>' + $(this).find("Keterangan").text() + ', dirasakan di ' + $(this).find("Dirasakan").text() + '');
            $(".bmkg").fadeIn(1000);
    	});
    }
