Data structure to save nested XML based data - php

Question

I obtain this type of response via curl:
<ArrayOfServerFile>
<ServerFile>
...
<FileType>Folder</FileType>
<Identifier>x123</Identifier>
<Name>Client Templates</Name>
...
</ServerFile>
<ServerFile>
...
<FileType>XpressDox Template</FileType>
<Identifier>y456</Identifier>
<Name>contact-information.xdtpl</Name>
...
</ServerFile>
...
</ArrayOfServerFile>
I want to save this info in a tree-like data structure.
I have tried something like this:
// Pseudo-code:
function run_procedure()
{
get XML data via curl
if FileType == 'Folder'
save name and other useful data into $tree_like_data_structure
run_procedure() // recursive call
else if FileType == 'XpressDox Template'
save name and other useful data into $tree_like_data_structure
}
var_dump($tree_like_data_structure);
The idea is to represent saved data like this:
[0][0] -> data
[1][0] -> data
[1][1] -> data
[1][2] -> [2][0] -> data
[2][1] -> data
[1][3] -> data
I am pretty sure that this is not so hard to accomplish but I have lost a lot of time without success. Any tip is very welcome. Thanks.-
EDIT 1
My main concern is how obtain [depth][element] indexes and how level data (type, name, content, etc).
EDIT 2
Basically this is a recursive programming problem. Maybe it can be done via while statements more easily than with a recursive function?

Try using SimpleXML with the DOM to create your array.
$dom = new DOMDocument;
$dom->loadXML('
<ArrayOfServerFile>
<ServerFile>
<FileType>Folder</FileType>
<Identifier>x123</Identifier>
<Name>Client Templates</Name>
</ServerFile>
</ArrayOfServerFile>');
if (!$dom) {
echo 'Error while parsing the document';
exit;
}
$s = simplexml_import_dom($dom);
echo $s->ServerFile[0]->FileType;
