PHP-General - Pagination from XML using PHP

Hi, I need to create pages with data parsed from XML into PHP.

---catalog.xml---
<?xml version="1.0" encoding="ISO-8859-1"?>
<Catalog>
<Category>
<Name>CAT 1</Name>
<Location>
<Id>C01</Id>
<Description>This is CAT 1, ID C01</Description>
</Location>
<Location>
<Id>C02</Id>
<Description>This is CAT 1, ID C02</Description>
</Location>
<Location>
<Id>C03</Id>
<Description>This is CAT 1, ID C03</Description>
</Location>
<Location>
<Id>C04</Id>
<Description>This is CAT 1, ID C04</Description>
</Location>
</Category>
<Category>
<Name>CAT 2</Name>
<Location>
<Id>C05</Id>
<Description>This is CAT 2, ID C05</Description>
</Location>
<Location>
<Id>C06</Id>
<Description>This is CAT2, ID C06</Description>
</Location>
<Location>
<Id>C07</Id>
<Description>This is CAT 2, ID C07</Description>
</Location>
<Location>
<Id>C08</Id>
<Description>This is CAT2, ID C08</Description>
</Location>
<Location>
<Id>C09</Id>
<Description>This is CAT2, ID C09</Description>
</Location>
<Location>
<Id>C10</Id>
<Description>This is CAT2, ID C10</Description>
</Location>
</Category>
</Catalog>

---search.php---
[php]

$catalog = simplexml_load_file("catalog.xml");

foreach($catalog->Category[1]->Name as $name)
foreach($catalog->Category[1]->Location as $site)
foreach($site->Id as $ID)
foreach($site->Description as $desc)
{
$all_data[$i]["Name"] = $name;
$all_data[$i]["ID"] = $ID;
$all_data[$i]["Description"] = $desc;
$i++;
}

$limit = 3;
$page = (int) $_GET['page'];
$page = $page > 1 ? $page : 1;
$start = $limit * ($page - 1);

for($i=$start; $i<($start+$limit); $i++) {
$content.="
".'<table><tr><td>'.$all_data[$i]["Name"].'<br />'."
".'<br />'.$all_data[$i]["ID"].'<br />'."
".'<br />'.$all_data[$i]["Description"].'</td></tr></table>'."
";
}

echo $content;

$pages = ceil(count($all_data) / $limit);

$links = array();

for($i=1; $i<=$pages; $i++) {
$links[] = "<a href=\?page=".$i.">".$i."</a>";
}

echo implode(" - ",$links);


---Output---

CAT 2

C06

This is CAT2, ID C06
CAT 2

C07

This is CAT 2, ID C07
1 - 2


---Problem---
1. The result is not showing the first ID Node C05

2. The page link is not working. When click on 2, it just brings me to the server error without indicating the error code.

Can someone advise me how should I overcome this?

Ok, I resolved the first problem due to the array. Now can someone tells me how to resolve the page link issue. Many thanks.

Thanks all, I got this resolved.
