<?php

$doc = new DOMDocument();

$doc->load( 'loaned.xml' );

 

$booklist = $doc->getElementsByTagName( "book" );

//$len = $musiclist->length;

foreach( $booklist as $book )

{

 //$sno = $song ->index[];

  $bookids = $book->getElementsByTagName( "ID" );

  $bookid = $bookids->item(0)->nodeValue;

 

  $booktitles= $book->getElementsByTagName( "title" );

  $booktitle = $booktitles->item(0)->nodeValue;

 

  $dates= $book->getElementsByTagName( "date" );

  $date= $dates->item(0)->nodeValue;

  echo "<b>$bookid - $booktitle - $date - $retdate - $sid - <a href=\"delete.php?bid=$bookid\">X</a> - <a href=\"modify.php?bid=$bookid\">Modify</a>\n</b><br>";
