I am using this code to render my rss :


$xml = new SimpleXMLExtended("<?xml version=\"1.0\" encoding=\"utf-8\"?>
<rss xmlns:g='http://base.google.com/ns/1.0' version='2.0'></rss>");
$channel = $xml->addChild("channel");
$channel->addChild("title", "Kidso");
$channel->addChild("link", "https://kidso.ro");
$channel->addChild("description", "Kidso");
foreach ($res as $record) {
$gtin = $this->db->select('ean13')->where('id_product', $record['pid'])->get('bebs_product')->row();
$item = $xml->addChild("item");
$item->addChild("g:id", $record['pid']);
//$item->addChild("id", $record['pid']);
$title_feild = "g:title";
$item->$title_feild = NULL;
$item->$title_feild->addCData($record['name']);
$desc_feild = "g:description";
$item->$desc_feild = NULL;
$item->$desc_feild->addCData($record['description']);
$item->addChild("g:link", $record['url']);
$item->addChild("g:image_link", $record['main_image']);
$item->addChild("g:availability", $record['qty'] > 0 ? "in stock" : "out of stock");
$item->addChild("g:sale_price", $record['product_price']);
$item->addChild("g:gtin", ($gtin ? $gtin->ean13 : ""));
$brand_feild = "g:brand";
$item->$brand_feild = NULL;
$item->$brand_feild->addCData($record['brand_name']);
}

The class i am using for the CDATA sections:


<?php

class SimpleXMLExtended extends SimpleXMLElement {
public function addCData($cdata_text) {
$node = dom_import_simplexml($this);
$no = $node->ownerDocument;
$node->appendChild($no->createCDATASection($cdata_text));
}
}

Now the CDATA items are shown correct with g: in the begining but on the others, g: is escaped from the names. The result is:


<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0">
<channel>
<title>Kidso</title>
<link>https://kidso.ro</link>
<description>Kidso</description>
</channel>
<item>
<id>9645</id>
<g:title>

How to prevent this escaping? I need all fields to be with g: prefix.



My Answer:
An RSS feed in PHP can be created using the SimpleXMLElement class to generate the XML structure of the feed. Here is an example code snippet to create an RSS feed in PHP:

php
// Create a new XML document
$xml = new SimpleXMLElement('');

// Add channel element
$channel = $xml->addChild('channel');
$channel->addChild('title', 'Example RSS Feed');
$channel->addChild('link', 'http://www.example.com');
$channel->addChild('description', 'This is an example RSS feed');

// Add items to the feed
$item = $channel->addChild('item');
$item->addChild('title', 'Item 1');
$item->addChild('link', 'http://www.example.com/item1');
$item->addChild('description', 'This is the description for Item 1');
$item->addChild('pubDate', date('D, d M Y H:i:s O'));

// Output the XML
header('Content-Type: application/rss+xml');
echo $xml->asXML();
?>


This code snippet creates a basic RSS feed with one item. You can add more items by duplicating the item element and setting the title, link, description, and pubDate values accordingly. Remember to set the appropriate headers for the XML content type before outputting the XML.
