How do I read this xml file?

[vigour]

I am trying to read a xml file and echo it to the screen. The xml file is located here if you want to download it:

http://www.thrutherockies.com/words.xml

And the php file:

http://www.thrutherockies.com/words.php

This is the code I am using but it will only show part of the content.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php

$xml = simplexml_load_file('words.xml');

foreach ($xml->register->table->record as $element)
	{
	echo "********** table1 **********";
	echo "<br>";
	$content = $element->content;
	$wordChunks = explode("\t", $content);
	for($i = 1; $i < count($wordChunks); $i++)
		{
		echo $i.": ". $wordChunks[$i];
		echo "<br>";
		}
	echo "<br>";	

foreach ($xml->register->table->record->table->record as $element2)
	{	
	echo "********** table2 **********";
	echo "<br>";
	$content2 = $element2->content2;
	$wordChunks = explode("\t", $content2);
	for($i2 = 1; $i2 < count($wordChunks); $i2++)
		{
		echo $i2.": ". $wordChunks[$i2];
		echo "<br>";
		}

foreach ($xml->register->table->record->table->record as $element3)
	{
	echo "********** table3 **********";
	echo "<br>";	
	$content3 = $element3->content3;
	$wordChunks = explode("\t", $content3);
	for($i3 = 1; $i3 < count($wordChunks); $i3++)
		{
		echo $i3.": ". $wordChunks[$i3];
		echo "<br>";
		}
	}			
	echo "<br>";
	echo "<br>";

	}

}
