XML Applications
This chapter demonstrates some small XML applications built on XML, HTML, XML DOM and JavaScript.
The XML Document Used
In this application we will use the "cd_catalog.xml" file.
Display the First CD in an HTML div Element
The following example gets the XML data from the first CD element and displays it in an HTML element with id="showCD". The displayCD() function is called when the page is loaded:
Example
i=0;
function displayCD()
{
artist=(x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue);
title=(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue);
year=(x[i].getElementsByTagName("YEAR")[0].childNodes[0].nodeValue);
txt="Artist: " + artist + "<br />Title: " + title + "<br />Year: "+ year;
document.getElementById("showCD").innerHTML=txt;
}

Navigate Between the CDs
To navigate between the CDs in the example above, add a next() and previous() function:
Example
{ // display the next CD, unless you are on the last CD
if (i<x.length-1)
{
i++;
displayCD();
}
}
function previous()
{ // displays the previous CD, unless you are on the first CD
if (i>0)
{
i--;
displayCD();
}
}
