how to merge xml files with root attributes? - php

Question

I have several xml files, and they all have attributes in root.
More or less this way:
FILE1.XML
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<item_root id="item01" name="Item 01">
<child>content 01</child>
</item_root>
FILE2.XML
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<item_root id="item02" name="Item 02">
<child>content 02</child>
</item_root>
... and so on.
I need to merge all the files in one, dynamically with php.
But as a result of what I'm doing, I can't get the root attributes.
The result looks something like this:
<?xml version="1.0"?>
<itens>
<item_root>
<child>content 01</child>
</item_root>
<item_root>
<child>content 02</child>
</item_root>
</itens>
But it should look like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<itens>
<item_root id="item01" name="Item 01">
<child>content 01</child>
</item_root>
<item_root id="item02" name="Item 02">
<child>content 02</child>
</item_root>
</itens>
My merge code looks like this:
<?php
$files= array(
'xmlitens/file1.xml',
'xmlitens/file2.xml'
);
$dom = new DOMDocument();
$itens = $dom->createElement('itens');
foreach ($files as $filename) {
$fileaddDom = new DOMDocument();
$fileaddDom->load($filename);
$itemroot = $dom->createElement('item_root');
if ($fileaddDom->documentElement) {
foreach ($fileaddDom->documentElement->childNodes as $node) {
$itemroot->appendChild(
$dom->importNode($node, TRUE)
);
}
}
$itens->appendChild($itemroot);
}
$dom->appendChild($itens);
?>
Is there an easy method to do this?

Answer 1

After I posted the question, the answer miraculously appeared to me.
Here is the solution I found:
$files= array(
'xmlitens/file1.xml',
'xmlitens/file2.xml'
);
$dom = new DOMDocument();
$itens = $dom->createElement('itens');
foreach ($files as $filename) {
$fileaddDom = new DOMDocument();
$fileaddDom->load($filename);
//This is the line that solves everything.
$node = $fileaddDom->getElementsByTagName("item_root")->item(0);
if ($fileaddDom->documentElement) {
$itens->appendChild( $dom->importNode($node, true) );
}
}
$dom->appendChild($itens);
Header('Content-type: text/xml');
print_r($dom->saveXML());
