1. Provide a data source for good XML files:

<?xml version= "1.0" encoding= "UTF-8"? ><catalog><cd><title>empire burlesque</title> <artist>bob dylan</artist><country>usa</country><company>columbia</company> <PRICE>10.90</PRICE><YEAR>1985</YEAR></CD>...</CATALOG>
2. A table that writes the display data for an HTML page 

<table border= "1px" >  <tr>  <td>  title:  </td>  <td id= "title" >  </td>  </tr>  <tr>  <td>  artist:  </td>  <td id= "Artist" >  </td>  </tr>  <tr>  <td>  Country:  </td>  <td id= " Country ">  </td>  </tr>  <tr>  <td>  Company:  </td>  <TD id= "Company" >  </td>  </tr>  <tr>  <td>  Price:  </td >  <td id= "Price" >  </td>  </tr>  <tr>  <td>  Year:  </td>  <td id= "Year" >  </td>  </tr>  <tr>  <td colspan= "2" >  <button onclick= "pre ()" > Previous </button>  <button onclick= "next ()" > next page </button>  </td>  </tr>  </table>

3. Writing JavaScript script files

<script type= "Text/javascript" >//Load XMLHttpRequest Object if (window.  XMLHttpRequest) {xmlhttp = new XMLHttpRequest ();  }else{xmlhttp = new ActiveXObject ("Microsoft.XMLHTTP"); } xmlhttp.open ("GET", "Newfile.xml", false);//Open link xmlhttp.send ();//Send data var xmldoc = xmlhttp.responsexml;//Get xmldoc piece var x = xmldoc.getelementsbytagname ("CD"), var i = 0;var title = document.getElementById ("title"); var artist = Document.ge Telementbyid ("artist"), var country = document.getElementById ("country"); var company = document.getElementById (" Company "), var price = document.getElementById (" price "), var year = document.getElementById (" year ");//Load Data function DISPLAYCD () {title.innerhtml = Xmldoc.getelementsbytagname ("title") [i].childnodes[0].nodevalue;artist.innerhtml = Xmldoc.getelementsbytagname ("ARTIST") [i].childnodes[0].nodevalue;country.innerhtml = Xmldoc.getelementsbytagname ("Country") [i].childnodes[0].nodevalue;company.innerhtml = Xmldoc.getelementsbytagname ("Company") [I].childnodes[0]. NodeValue;price.innerhtml = Xmldoc.getelementsbytagname ("Price") [i].childnodes[0].nodevalue;year.innerhtml = Xmldoc.getelementsbytagname ("Year") [I].childnodes[0].nodevalue;} Previous page, index minus one, if less than 0 equals zero function pre () {i--;if (i < 0) {i = 0;} DISPLAYCD ();}  Next function Next () {i++;d isplaycd ();} </script>
4. Load data after page load is complete 

<body onload= "DISPLAYCD ()" >
