using the DomDocument to create RSS

[codecowboy]

Hi,

I am trying to add to an rss file using the dom. Here is my code:

<?php

#load an XML document into the DOM
$dom = new DomDocument();
$dom -> load("PHPDocument13.xml");

#create elements
$channel = $dom->createElement("channel");
$item =  $dom -> createElement("item");
$title =  $dom -> createElement("title");
$link = $dom -> createElement("link");
$description =    $dom -> createElement("description");

#create text nodes
$titleText =  $dom -> createTextNode("Php Developer");
$linkText = $dom -> createTextNode("www.fliwox.com");
$descriptionText =    $dom -> createTextNode("PHP developers needed for fast paced development environment.");

#append the text nodes to the inner nested elements
$title->appendChild($titleText);
$link->appendChild($linkText);
$description->appendChild($descriptionText);

#append the inner nested elements to the <title> element
$item -> appendChild($title);
$item -> appendChild($link);
$item -> appendChild($description);

//append the <item> element to the <channel> element
$channel->appendChild($item);

#append the <channel> element to the root element <rss>
$dom->documentElement->appendChild($channel);

#create a new enlarged xml document
$dom -> save("new.xml");

?>

This is the output of my code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">

<channel>
<title>W3Schools Home Page</title>
<link>http://www.w3schools.com</link>
<description>Free web building tutorials</description>
<item>
<title>RSS Tutorial</title>
<link>http://www.w3schools.com/rss</link>
<description>New RSS tutorial on W3Schools</description>
</item>
<item>
<title>XML Tutorial</title>
<link>http://www.w3schools.com/xml</link>
<description>New XML tutorial on W3Schools</description>
</item>
</channel>

<channel><item><title>Php Developer</title><link>www.fliwox.com</link><description>PHP developers needed for fast paced development environment.</description></item></channel>
</rss>

Do you notice how my script appended another channel element at the end as opposed to appending the <item> to the <channel> element? How can I change my script so that it just appends the <item> within the <channel> tag?

Thank you 🆒

now, i'm pretty new to xml and stuff in php but... if I am reading this properly, you're "making" it create the new channel etc.

#create elements
$channel = $dom->createElement("channel");
$item =  $dom -> createElement("item");
$title =  $dom -> createElement("title");
$link = $dom -> createElement("link");
$description =    $dom -> createElement("description"); 

That is creating a new set of elements, so now when you are adding them into the xml file, it's just making new ones. There should be a way to get the current channel from the xml document, and from there append using that channel.

Let me know how it works, i'd be interested to figure this one out too 😛
