Hi, I'm having problems loading data from an XML file.
It works fine with IE and Safari. It also works fine with Firefox provided I browse the files on my local drive. However, when i upload the files to the server and browse via the internet, Forefox doesn't perform as it should. Has anyone had this problem? Thanks.
It seems to go wrong after the line:
HeadingTpe = Heading[j].substring(0,1);

Scripts:

// JScript File
Heading = ["?. Incomplete","A. Corporate Strategy","B. Organisational Effectiveness",
"C. Operational Effectiveness","D. Business Tools"];
var xmlFile ='tipFile.xml';
var xmlDoc = null;
var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf('safari/') != -1) { // code for Safari, use XMLHttpRequest() instead of .load()
XmlHTTP = new XMLHttpRequest();
XmlHTTP.open('get', xmlFile, false);
XmlHTTP.send('');
xmlDoc = XmlHTTP.responseXML;}
else if (window.ActiveXObject) { // code for IE
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load(xmlFile);}
else if (document.implementation.createDocument) { // code for Mozilla, Firefox, Opera, etc.
xmlDoc = document.implementation.createDocument('','',null) ;
xmlDoc.async = false;
xmlDoc.load(xmlFile);}
else{
alert('Your browser JavaScript is enabled, but it cannot handle this script');
}
if (xmlDoc != null){
var x = xmlDoc.getElementsByTagName("tip");
for (j=1;j<=4;j++){
document.write('<li>' + Heading[j].substr(3,Heading[j].length) + '<ol class = "L4">');
HeadingTpe = Heading[j].substring(0,1);
for (i=0;i<x.length;i++){
type = x[i].getElementsByTagName('type')[0].firstChild.nodeValue;
file = x[i].getElementsByTagName('file')[0].firstChild.nodeValue;
title = x[i].getElementsByTagName('title')[0].firstChild.nodeValue;
TipDte = file.substring(6,8) + file.substring(9,11);
if (type == HeadingTpe){
document.write('<li><a href = "' + file +'">'+ title + '</a></li>' );
}
}
document.write('</ol></li>');
}
}

Hi,

After turning grey, I decided to take another approach. I now have all browsers behaving. Thanks for all who put their heads to the wheel.

Jackson.

Hi guys,

If anyone is interested, I did manage to get this to work. At least in Firefox, IE and Safari on a Windows environment. I'd be interested to hear if it falls over on any other platform. (obviously the links go nowhere in this demo).

ShowXML.js

// JScript File

function GetXMLdoc(xmlFile){
xmlDoc.async = false;
xmlDoc.load(xmlFile);
}
function loadXML(xmlFile){
if (window.ActiveXObject) {// code for IE
try {xmlDoc = new ActiveXObject("Msxml2.XMLHTTP"); // newer IE
GetXMLdoc(xmlFile);}
catch(e){
try{xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); // older IE
GetXMLdoc(xmlFile);}
catch(e){}}} // exit without xmlDoc}
else if (window.XMLHttpRequest) { // Mozilla, Safari,...
xmlHTTP = new XMLHttpRequest();
if (xmlHTTP.overrideMimeType) {xmlHTTP.overrideMimeType('text/xml')}
xmlHTTP.open('get', xmlFile, false);
xmlHTTP.send('');
xmlDoc = xmlHTTP.responseXML;}
else if (document.implementation.createDocument) { // code for other
xmlDoc = document.implementation.createDocument('','',null) ;
GetXMLdoc(xmlFile);}
else{
alert('Your browser JavaScript is enabled, but cannot handle this script');// if all else fails display message
}
}
var xmlDoc = null;
loadXML('tipFile.xml');
if (xmlDoc != null){
var doc = document.title;
var len = doc.length;
Dte = new Date();
var MaxDte = Dte.getFullYear() + '';
var Mth = '0' + (Dte.getMonth() + 1);
var heading = xmlDoc.getElementsByTagName('heading');
var x = xmlDoc.getElementsByTagName('tip');
MaxDte = MaxDte.substring(2,4) + Mth.substring(Mth.length-2,Mth.length);
for (j=1;j<=4;j++){
h = heading[j].firstChild.nodeValue;
document.write('<li>' + h.substr(3,h.length) + '<ol class = "L4">');
HeadingTpe = h.substring(0,1);
for (i=0;i<x.length;i++){
type = x[i].getElementsByTagName('type')[0].firstChild.nodeValue;
file = x[i].getElementsByTagName('file')[0].firstChild.nodeValue;
title = x[i].getElementsByTagName('title')[0].firstChild.nodeValue;
TipDte = file.substring(6,8) + file.substring(9,11);
if (type == h.substring(0,1)){
if (TipDte <= MaxDte){
document.write('<li><a href = "' + file +'">'+ title + '</a></li>' );
}
}
}
document.write('</ol></li>');
}
}
