weather file - accessing xml data

hi -
i downloaded some data from a weather service that is in an xml file.
["parameters"]=> object(SimpleXMLElement)#9 (4) { ["temperature"]=> array(2)
{ [0]=> object(SimpleXMLElement)#11 (2) { ["name"]=> string(25) "Daily
Maximum Temperature" ["value"]=> array(6) { [0]=>
object(SimpleXMLElement)#16 (0) { } [1]=> string(2) "84" [2]=> string(2)
"89" [3]=> string(2) "87" [4]=> string(2) "82" [5]=> string(2) "78" } }
[1]=> object(SimpleXMLElement)#12 (2) { ["name"]=> string(25) "Daily Minimum
Temperature" ["value"]=> array(5) { [0]=> string(2) "48" [1]=> string(2)
"54" [2]=> string(2) "61" [3]=> string(2) "60" [4]=> string(2) "61" } } }

i need to get the temperatures out of that with simplexml methods.

i just cant come up with the syntax to access the array indexes of each
element of a given object.

any help is very cool.
thank you,
jim

Re: weather file - accessing xml data

hi -

i am going to try to use regular expressions to get my values.
i am frustrated that the formart of the file doesnt seem to be
able to be parsed by simplexml.

thanks anyways,
jim

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



would be a 'segment'...a 'single segment'
would be one of many 'segments', or 'multiple segments'





$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];
}
