RSS Reader with PHP and AJAX

[hitech]

I am using the following PHP code to parse and show the RSS Feeds:

 

<?php

    // ***** BEGIN ***** get the q parameter from URL  ***** BEGIN *****

    $q=$_GET["q"];//find out which feed was selected

    if($q=="Google")

    {

        $xml=("http://rss.terra.com.br/0,,EI1,00.xml");

    }

    elseif($q=="MSNBC")

    {

        $xml=("http://feeds.folha.uol.com.br/folha/emcimadahora/rss091.xml");

    }

    $xmlDoc = new DOMDocument();

    $xmlDoc->load($xml);

 

    // ***** BEGIN ***** get elements from "<channel>"  ***** BEGIN *****

    $channel=$xmlDoc->getElementsByTagName('channel')->item(0);

    $channel_title = $channel->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;

    $channel_link = $channel->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;

    $channel_desc = $channel->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;

 

    //***** BEGIN ***** output elements from "<channel>" ***** BEGIN *****

    echo("<p><a href='" . $channel_link . "'>" . $channel_title . "</a>");

    echo("<br />");

    echo($channel_desc . "</p>");

 

    // ***** BEGIN ***** get and output "<item>" elements ***** BEGIN *****

    $x=$xmlDoc->getElementsByTagName('item');

    for ($i=0; $i<=10); $i++)

    {

        $item_title=$x->item($i)->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;

        $item_link=$x->item($i)->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;

        $item_desc=$x->item($i)->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;

        echo ("<p><a href='" . $item_link . "'>" . $item_title . "</a>");

        echo ("<br />");

        echo ($item_desc . "</p>");

        echo("<hr>");

    }

?>

 

In this code, the loop for ($i=0; $i<=10); $i++) count 10 items of the feed.

 

How can I parse all items of the feed? I tryed:

    for ($i=0; $i<=count($x.length); $i++) but doesn´t work.

 

Thanks,

Helcio
