How to append new elemnt to XML-file using php DOMdocument? - php

Question

I have this test.xml:
<?xml version="1.0"?>
<Images>
<Image>
<Id>765</Id>
<Title>Img title 1</Title>
<Name>some_path_to_img.jpg</Name>
</Image>
</Images>
I try to append new '<Image>' to '<Images>', but without success.
Here is my code:
function update_xml_file() {
$xml = new DOMDocument();
$xml->load(file_get_contents('test.xml'));
$xml->formatOutput = true;
$base_node = $xml->getElementsByTagName('Images')->item(0);
$newimage = $xml->createElement("Image");
$img_id = $xml->createElement("Id");
$img_title = $xml->createElement("Title");
$img_name = $xml->createElement("Name");
$img_id->nodeValue = '766';
$img_title->nodeValue = 'Image title 2';
$img_name->nodeValue = 'some_path_to_img2.jpg';
$newimage->appendChild($img_id);
$newimage->appendChild($img_title);
$newimage->appendChild($img_name);
$base_node->appendChild($newimage);
umask();
$xml->save("test.xml");
}
Looking around for related discussions didn't help me.
Thanks for your time.

Answer 1

You have a little typo in the code which loads the xml data.
Change it to:
$xml->loadXML(file_get_contents('test.xml'));
or ( better)
$xml->load('test.xml');
Refer to the documentation of DOMDocument::loadXML() and DOMDocument::load()

You can also use this package from github to make it simple http://github.com/toureiliass/xdt
You can do it in a few line of code
$con = new XDT();
$con->connect('test.xml');
$con->getDocumentRootElement()->append('<image><id>765</id><title>some title</title><name>some_path_to_image.jpg</name></image>');
$con->save();
