SimpleXML showing unexpected behaviour - php

Question

I have a XML file named conf.xml and I'm trying to display the contents of this XML file via a simple php script (placed in the same directory) as follows:
conf.xml
<?xml version="1.0" encoding="UTF-8"?>
<registration_info>
<organization name="Home" />
</registration_info>
PHP script:
$data=simplexml_load_file("conf.xml");
$node=$data->registration_info;
$subnode=$node->organization;
echo (string) $subnode['name']; // Displays null string
I feel that there's nothing wrong with the code but the output is unexpected as the anticipated output was "Home". Can anyone please help me solve this problem and explain me the solution?
Thanks in advance.

Answer 1

The existing answer given here is correct, but the explanations are rather confused. SimpleXML is not hiding the root node of your XML, it's just that the object you have already is that node.
Each SimpleXMLElement object represents a particular node in the XML document's tree. There is no separate object in SimpleXML representing "the whole document", so when you run simplexml_load_file, the object returned is the SimpleXMLElement for the root node.
$root_node = simplexml_load_file("conf.xml");
echo $root_node->getName(); // registration_info
$child_node = $root_node->organization;
// Short for $root_node->organization[0];
// meaning "get the first child with name 'organization'
echo $child_node->getName(); // organization

Try this hope this will help you out. You have to just remove $node=$data->registration_info;
Try this snippet here
<?php
ini_set('display_errors', 1);
$data=simplexml_load_file("conf.xml");
$subnode=$data->organization;
echo (string) $subnode['name'];
Output: print_r($data)
SimpleXMLElement Object
(
[organization] => SimpleXMLElement Object
(
[#attributes] => Array
(
[name] => Home
)
)
)
