Need some help with parsing an XML file

Hello everyone

I am learning how to parse XML files with PHP. And I cant figure out how to do something.

Here is a sample XML file that I am trying to parse:

Quote:

<?xml version="1.0"?>
<emailsList>
<email no="1">
<from>
whatever@yahoo.com
</from>
<to>
yyy@yahoo.com
</to>
<subject>
Just te test
</subject>
<body>
Helloooooo
</body>
</email>
<email no="2">
<from>
whatever@hotmail.com
</from>
<to>
yyy@hotmail.com
</to>
<subject>
Just to test2
</subject>
<body>
Hiiiiiiii
</body>
</email>
</emailsList>

I am trying to parse this file so if no.1 is entered the information from the 1st node is shown. How can I do this? any help is appreciated.
Here is the php code to prase the xml document

Quote:

<?php

$xml = xml_parser_create();
$obj = new Parser_Object; // a class to assist with parsing

xml_set_object($xml,$obj);
xml_set_element_handler($xml, 'start_element', 'end_element');
xml_set_character_data_handler($xml, 'character_data');
xml_parser_set_option($xml, XML_OPTION_CASE_FOLDING, false);

$fp = fopen('data.xml', 'r') or die("Can't read XML data.");
while ($data = fread($fp, 4096)) {
xml_parse($xml, $data, feof($fp)) or die("Can't parse XML data");
}
fclose($fp);

xml_parser_free($xml);

class pc_RSS_item
{
var $from = '';
var $to = '';
var $subject = '';
var $body='';
function display() {
printf('<p><a href="%s">%s</a><br />%s</p>',
$this->link,htmlspecialchars($this->title),
htmlspecialchars($this->description));
}
}

class pc_RSS_parser
{
var $tag;
var $item;
function start_element($parser, $tag, $attributes)
{
if ('item' == $tag) {
$this->item = new pc_RSS_item;
} elseif (!empty($this->item)) {
$this->tag = $tag;
}
}
function end_element($parser, $tag) {
if ('item' == $tag) {
$this->item->display();
unset($this->item);
}
}
function character_data($parser, $data) {
if (!empty($this->item)) {
if (isset($this->item->{$this->tag})) {
$this->item->{$this->tag} .= trim($data);
}
}
}
}
?>
