Manipulating nodes in DomDocument and transform it into an array - php

Question

I've an XML looking this way :
<?xml version="1.0" ?>
<rss version="2.0">
<channel>
<title>get_news_category</title>
<item>
<id>10502</id>
<title>Cheesecake</title>
<summary>SummaryBlahblah</summary>
</item>
<item>
<id>13236</id>
<title>Moto</title>
<summary>summary blahblah</summary>
</item>
And I want to put the items into an php array.
I've done so far:
$nodes = $dom->getElementsByTagName('item')->item(0);
$values = $nodes->getElementsByTagName("*");
$articles = array();
foreach ($values as $node) {
$articles[$node->nodeName] = $node->nodeValue;
}
var_dump($articles);
Which only returns me in an array, the 1 <item> element. which is logic because i told him ->item(0).
So how to select all the items in order to put all the items into an array ?
Thanks.

Answer 1

use $nodes->length
$dom = new DOMDocument();
$dom->loadHTML($html);
$nodes = $dom->getElementsByTagName('item');
for($i=0; $i<$nodes->length; $i++){
$values = $nodes->item($i)->getElementsByTagName("*");
$articles = array();
foreach ($values as $num => $node) {
$articles[$i][$node->nodeName] = $node->nodeValue;
}
var_dump($articles);
}

You need to iterate the $nodes.
$nodes = $dom->getElementsByTagName('item');
for ($i = 0; $i < $nodes->length; $i++)
{
// Lets grab the node
$values = $nodes->item($i)->getElementsByTagName("*");
}
