<p class="intro">This chapter demonstrates a small XML application built with
HTML and JavaScript</p>
<hr />
<h2>The XML Example Document</h2>
<p>Look at the following XML document ("cd_catalog.xml"), that represents a CD
catalog:</p>
<table border="1" width="100%" class="ex" cellspacing="0">
<tr>
<td>
<pre><?xml version="1.0" encoding="ISO-8859-1"?>
<CATALOG>
<CD>
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Bob Dylan</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
.
.
... more ...
.</pre>
</td>
</tr>
</table>
<p><a target="_blank" href="cd_catalog.xml">View the full "cd_catalog.xml" file in
your browser</a>.</p>
<hr />
<h2>Load the XML Document</h2>
<p>To load the XML document (cd_catalog.xml), we use the same code as we used in
the XML Parser chapter:</p>
<table border="1" width="100%" class="ex" cellspacing="0">
<tr>
<td>
<pre>var xmlDoc;
if (window.ActiveXObject)
{// code for IE
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
}
else if (document.implementation.createDocument)
{// code for Firefox, Mozilla, Opera, etc.
xmlDoc=document.implementation.createDocument("","",null);
}
else
{
alert('Your browser cannot handle this script');
}
xmlDoc.async=false;
xmlDoc.load("cd_catalog.xml");</pre>
</td>
</tr>
</table>
<p>After the execution of this code, xmlDoc is an XML DOM object, accessible by
JavaScript.</p>
<hr />
<h2>Display XML Data as an HTML Table</h2>
<p>The following code displays an HTML table filled with data
from the XML DOM object:</p>
<table border="1" width="100%" class="ex" cellspacing="0">
<tr>
<td>
<pre>document.write("<table border='1'>");</pre>
<pre>var x=xmlDoc.getElementsByTagName("CD");
for (var i=0;i<x.length;i++)
{
document.write("<tr>");
document.write("<td>");
document.write(
x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue);
document.write("</td>");
document.write("<td>");
document.write(
x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue);
document.write("</td>");
document.write("</tr>");
}
document.write("</table>");</pre>
</td>
</tr>
</table>
<p>For each CD element in the XML document, a table row is created. Each table
row contains two table data cells with ARTIST and TITLE data from the current CD
element.</p>
<p>Try it yourself:
<a target="_blank" href="tryit.asp@filename=tryxml_app_table">See how the XML data is displayed inside an HTML table</a>.</p>
