XML Parsing Problem?

[ankur625]

I build a XML file as bellow, in which main "list" tag contain all data. There are multiple categories and each category have its multiple products.
I'm creating a PHP script to parse and show products category wise. See the script bellow. It's getting difficult for me to categorize each product.
I need to show each product just bellow its category, but it's showing all products. How can I filter each product category wise?

    <?xml version="1.0" encoding="ISO-8859-1"?>

<list>
<category>
<catname>PC</catname>
<game>
<gamename>Game1</gamename>
<id>001</id>
<desc>some desc of game1.</desc>
</game>
<game>
<gamename>Game2</gamename>
<id>002</id>
<desc>some desc of game2.</desc>
</game>
</category>

<category>
<catname>MAC</catname>
<game>
<gamename>Game3</gamename>
<id>003</id>
<desc>some desc of game3.</desc>
</game>
<game>
<gamename>Game4</gamename>
<id>004</id>
<desc>some desc of game4.</desc>
</game>
</category>

</list>

Here is PHP code I'm using,

    <?php
    $XML = new DOMDocument();
    libxml_use_internal_errors(true);
    $XML->load("test.xml");
    if(!$XML){
    echo "can not load XML file";
    exit();
    }
    $category = $XML->getElementsByTagName("category");
    foreach( $category as $value ){
    $Names = $value->getElementsByTagName("catname");
    $Name  = $Names->item(0)->nodeValue;
    echo $Name . "<br />";

$game = $XML->getElementsByTagName("game");
// second loop to get value inside game tag
foreach( $game as $value2 ){
$gamenames = $value2->getElementsByTagName("gamename");
$gamename  = $gamenames->item(0)->nodeValue;
echo $gamename . "<br />";
}

}
?>

Here is output I'm getting
PC

Game1

Game2

Game3

Game4

MAC

Game1

Game2

Game3

Game4

But I want to show,

PC

Game1

Game2

MAC

Game1

Game2

Am I not looping properly or is there other method to parse this type of XML structure.

Thank You!

To start your game loop you start at the beginning of the XML document with

    $game = $XML->getElementsByTagName("game"); 

Which is finding ALL game tags in the document, you probably want to use something like (untested)

    $game = $value->getElementsByTagName("game"); 

That way you are only selecting game tags that are children of the given category.
