Let me start by stating I am a Newb and while I have created a fair bit of html code, I am trying to move into XML and Javascipt for my own edification. That being said, I have run into a problem (which I researched and found similar issues) that has stumped me. The funny thing the code worked a few times under Firefox but now it works on nothing and I can't seem to find the issue. I did use the IE Console to check file open status etc.. but no joy. As the subject line indicates I can't seem to list the XML tag(s) in a table I am building for a web page. Here is the relevant html code and associated XML file. Any assistance would be appreciated.
HTML Code
<script>
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","event.xml",true);
xmlhttp.onreadystatechange=function()
{
if(xmlhttp.readyState!=4)return;
if(xmlhttp.status==200)
alert(xmlhttp.responseText);
else
alert("Request failed!");
};
//onreadystatechange
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var y=xmlDoc.getElementsByTagName("months");
for (i=0;i<y.length;i++)
{
document.write("<tr bgcolor='#6CA6CD'>");
document.write("<th>");
document.write(month[i].getElementsByTagName("month1")[0].childNodes[0].nodeValue);
document.write("</th>");
document.write("<th>");
document.write(month[i].getElementsByTagName("month2")[0].childNodes[0].nodeValue);
document.write("</th>");
document.write("</tr>");
}
var x=xmlDoc.getElementsByTagName("month_event");
for (i=0;i<x.length;i++)
{
document.write("<tr><td bgcolor='white'>");
document.write("<b> ");
document.write(x[i].getElementsByTagName("month1_date")[0].childNodes[0].nodeValue);
document.write("</b> - ");
document.write(x[i].getElementsByTagName("month1_day")[0].childNodes[0].nodeValue);
document.write(" - ");
document.write(x[i].getElementsByTagName("month1_time")[0].childNodes[0].nodeValue);
document.write(" - ");
document.write(x[i].getElementsByTagName("month1_evdescription")[0].childNodes[0].nodeValue);
document.write("</td><td bgcolor='lightgrey'>");
document.write("<b> ");
document.write(x[i].getElementsByTagName("month2_date")[0].childNodes[0].nodeValue);
document.write("</b> - ");
document.write(x[i].getElementsByTagName("month2_day")[0].childNodes[0].nodeValue);
document.write(" - ");
document.write(x[i].getElementsByTagName("month2_time")[0].childNodes[0].nodeValue);
document.write(" - ");
document.write(x[i].getElementsByTagName("month2_evdescription")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");

getElementsByTagName
returns a NodeList, not an array, so use x.item(i)
.
To get it to work, make the following changes:
1) change true to false for synchronous (line 11)
xmlhttp.open("GET","event.xml",false);
2) declare the month
variable (line 31+)
for (i=0;i<y.length;i++)
{
var month = y.item(i); // insert this line
document.write("<tr bgcolor='#6CA6CD'>");
document.write("<th>");
document.write(month.getElementsByTagName("month1").item(0).childNodes[0].nodeValue); // !!!
3) use .item(i)
and .item(0)
rather than [i]
and [0]
(line 45+)
var x=xmlDoc.getElementsByTagName("month_event");
for (i=0;i<x.length;i++)
{
document.write("<tr><td bgcolor='white'>");
document.write("<b>test ");
document.write(x.item(i).getElementsByTagName("month1_date").item(0).childNodes[0].nodeValue);
