How to load string back xml with simpleXML in PHP? - php

Question

Would anyone know how i can "explode" a string back into "normal" xml format?
I found this script (ref:gooseflight,2010) that looks like it can do the job but the output comes out stuck together.
Here's the code:
enter code herefunction combineXML($file)
{
global $xmlstr;
$xml = simplexml_load_file($file);
foreach($xml as $element)
$xmlstr .= $element->asXML();
}
$files[] = "tmp.xml";
$files[] = "traduction.xml";
$xmlstr = '<CAB>';
foreach ($files as $file)
combineXML($file);
$xmlstr .= '</CAB>';
// Convert string to XML for further processing
$xml = simplexml_load_string($xmlstr);
$bytes = file_put_contents("combined.xml", $xml->asXML())
Here is the output:
<?xml version="1.0" encoding="UTF-8"?>
<CAB>
<CABO>XXXXXXXXXX0987650003</CABO><ACTIVITY>NONE</ACTIVITY><BEORI>blablaE</BEORI>BEDEST>blabla</BEDEST><NATRELA>more blabla</NATRELA><ANE>2014</ANE><NODEP>1111</NODEP>
</CAB>
So how could i seperate the nodes to look like this?:
<?xml version="1.0" encoding="UTF-8"?>
<CAB>
<CABO>XXXXXXXXXX0987650003</CABO>
<ACTIVITY>NONE</ACTIVITY>
<BEORI>blablaE</BEORI>
<BEDEST>blabla</BEDEST>
<NATRELA>more blabla</NATRELA>
<ANE>2014</ANE>
<NODEP>1111</NODEP>
.....
</CAB>
Would anyone know how to fix it?

I would suggest to use DomDocument class to save the XML; check this:
$dom_obj = new DOMDocument();
$dom_obj->loadXML($file);
// Do all your changes to the file by using DomDocument command (e.g. CreateElement, CreateAttribute, etc)
$dom_obj->formatOutput = true;
$dom_obj->save($file);
