listen jim, don't try to access the arrays by index. just use a foreach.
however, if you just want to use regex for simplicity and you don't need to
know attributes and such, try these:

==========

hint: segment is a node

<?xml>
<root>
<records> would be a 'segment'...a 'single segment'
<record /> would be one of many 'segments', or 'multiple segments'
<record />
<record />
</records>
</root>

$records = getSingleSegment('records', $xml);
$records = getMultipleSegments('record', $records);
foreach ($records as $record)
{
// you get the idea
}

==========

function getMultipleSegments($segment, $xml)
{
$pattern = "/<(" . $segment . ")>(.*?)<\/\\1>/si";
preg_match_all($pattern, $xml, $matches);
foreach ($matches[2] as $content)
{
$output[] = $content;
}
return $output;
}

function getMultipleSegmentNames($xml)
{
$output = array();
$pattern = "/<([^>]+)>.*?<\/\\1>/si";
preg_match_all($pattern, $xml, $matches);
foreach ($matches[1] as $content)
{
$output[] = $content;
}
return $output;
}

function getSegmentValue($xml, $emptyDefault = '')
{
$pattern = "/<([^>]+)>(.*?)<\/\\1>/si";
preg_match($pattern, $xml, $match);
$value = $match[2];
if ($value == ''){ $value = $emptyDefault; }
return htmlDecode($value);
}

function getSingleSegment($segment, $xml)
{
$output = '';
$pattern = "/<(" . $segment . ")>(.*?)<\/\\1>/si";
preg_match_all($pattern, $xml, $matches);
foreach ($matches[0] as $content)
{
$output .= $content;
}
return $output;
}

function getSingleSegmentName($xml)
{
$output = '';
$pattern = "/<([^>]+)>.*?<\/\\1>/si";
preg_match($pattern, $xml, $match);
return $match[1];
}
