Dom parsing issue empty result - php

Question

<tr class='Jed01'>
<td height='20' class='JEDResult'>1</td>
<td height='30' class='JEDResult'>26.04.2013</td>
<td height='30' class='JEDResult'>19:43</td>
<td height='30' class='JEDResult'>Processing</td>
<td height='30' class='JEDResult'><a href="#" pressed="GetInfo(1233);" title=''>Jeddah</a></td>
</tr>
Result = first step - date - time - state - place
First of all I am new to PHP and I am trying to parse this data to my web via PHP - DOM as recommended to me before on Stackoverflow. In the code below I have called all classes to get data but I can't get any result while there is no any issue. So please where it could be my issue?
Thanks from now
<?php
$input = "www.kalkatawi.com/luai.html"
$html = new DOMDocument();
$html->loadHTML($input);
foreach($html->getElementsByTagName('tr') as $tr)
{
if($tr->getAttribute('class') == 'Jed01')
{
foreach($html->getElementsByTagName('td') as $td)
{
if($td->getAttribute('class') == 'JEDResult')
{
echo ($td->nodeValue);
}
}
}
}
?>

Dont forget those semi colons ;)
Try this;
<?php
$input = file_get_contents("http://www.kalkatawi.com/luai.html");
$html = new DOMDocument();
$html->loadHTML($input);
foreach($html->getElementsByTagName('tr') as $tr)
{
if($tr->getAttribute('class') == 'Jed01')
{
foreach($tr->getElementsByTagName('td') as $td)
{
if($td->getAttribute('class') == 'JEDResult')
{
echo ($td->nodeValue);
echo '<br/>';
}
}
}
echo '<br/><br/>';
}
?>
Should output;

There are several problems with this code.
Loading the HTML
$input = 'MyLink';
$html = new DOMDocument();
$html->loadHTML($input);
This code attempts to treat the string 'MyLink' as HTML, which obviously it is not. If that's your actual code then nothing would work beyond this point. Either provide proper HTML input or use loadHTMLFile to load HTML from a file.
Comparisons are case-sensitive
On the one hand there is this:
<tr class='Jed01'>
And on the other this:
if($tr->getAttribute('class') == 'JED01')
Since 'Jed01' != 'JED01' this will never be true. Either fix the casing or use some other mechanism such as stricmp to compare the classes.
Objects cannot be printed
This results in a fatal error:
echo ($td);
What it should be instead: most likely echo $td->nodeValue, but other possibilities are open depending on what you want to do.
But you could do it much more easily with XPath
$xpath = new DOMXPath($html);
$query = "//tr[#class='Jed01']//td[#class='JEDResult']"; // google XPath syntax
foreach ($xpath->query($query) as $node) {
print_r($node->nodeValue);
}
