PHP custom sort preg_match_all? - php

Question

So I know there are articles out there about custom ordering but I think my situation may be a little different (Or could just be my workaround sucks :P ). Here is the quick scenario.
I pull XML data from curl off a report url that we have. (not properly formatted!) So let's use the following example: I get the following data back in one long list.
<Site>My Sites</Site>
<Customer>PHPSTEVE</Customer>
<Name>Griswald</Name>
<Site> Evil Dead</Site>
<Customer>Bruce</Customer>
<Name>Campbell</Name>
I can't use the XML function because the format header is incorrect so I won't get into that.. So instead I use a preg_match_all
preg_match_all("/<Site>(.*?)<\/Site>|<Customer>(.*?)<\/Customer>|<Name>(.*?)<\/Name>/is", $resp, $output_array[]);
Then I go through and I know this is not good but it works..
foreach(array_reverse($output_array[0][0]) as $info){
$myinfo = $info . $myinfo;
}
Everything works as I use a str_replace and just put in my table tags etc.. Obviously I'm doing the reading in reverse.. it's ok I want it that way for this.
Site | Customer | Name
----------+----------+------
Evil Dead | Bruce | Campbell
What if I want "Customer" field first? So basically I'm changing the horizontal order of Site and Customer etc... Remember there are multiple records all in a line so I am trying to figure out how I would move Customer to where I want it.. or any field for that matter. Based off of my code above, I don't believe I can accomplish it the way I want to so I'm not sure of another way to do it.
I would like to report it as this:
Customer | Site | Name
---------+-----------+------
Bruce | Evil Dead | Campbell
Any help would be appreciated. NOTE: I don't care about reading bottom up or top down.. just field changes. Thanks
UPDATE: The XMl issue I run into is:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<results>
<Site>My Sites</Site>
<Customer>PHPSTEVE</Customer>
<Name>Griswald</Name>
<Site> Evil Dead</Site>
<Customer>Bruce</Customer>
<Name>Campbell</Name>
</results>

Maybe something like this?
function sortCustomerKeys($a, $b)
{
if ( $a == 'Customer' && $b != 'Customer' ) {
return 1;
} else if ( $a != 'Customer' && $b == 'Customer' ) {
return -1;
}
return strnatcasecmp($a, $b);
}
$customers = array();
$advance = array(
'Customer' => 0,
'Name' => 0,
'Site' => 0
);
if ( preg_match_all('#<(Customer|Name|Site)>\\s*(.*?)\\s*</\\1>#is', $resp, $m) ) {
for ($i = 0, $j = 0; $i < count($m[1]); $i++) {
$tag = $m[1][$i];
$value = $m[2][$i];
$customers[$j][$tag] = $value;
$advance[$tag] = 1;
if ( array_sum($advance) == count($advance) ) {
$advance = array(
'Customer' => 0,
'Name' => 0,
'Site' => 0
);
uksort($customers[$j], 'sortCustomerKeys');
$j++;
}
}
}
var_dump($customers);
