display value from a xml file

[snowscar]

I am trying to print some value from an xml file. I am sorry but I dont knw much of php and I really need help.
the xml file is http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=RPVI

This is the code i have so far but none of it seems to work.
I just want it to display some items like city, wind direction, speed,etc.

How can I do this ?

<?php
if(!$xml=simplexml_load_file('http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=RPVI')){
trigger_error('Error reading XML file',E_USER_ERROR);
}

//Trying to print the credit name
print $xml->current_observation->credit . "\n";

//Trying another way to print it
foreach ($xml->items as $item) {
$city = $item['city'];
$desc = $item['description'];
echo "<b>".$city."</b><br>";
if($desc) echo $desc."<br>";

}?>

Hi

this code is long

but try it

<?php
//$file = "data.xml";
$file = "cgal_2.xml";
$xml_parser = xml_parser_create();

if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}

$data = fread($fp, filesize($file));
fclose($fp);

xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, false);

xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);

$params = array();
$level = array();
$i=0;?><table width="50&#37;" border="1" cellspacing="0" cellpadding="0"><tr>
<? foreach ($vals as $xml_elem) {

if ($xml_elem['type'] == 'open') {
if (array_key_exists('attributes',$xml_elem)) {
list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
} else {
$level[$xml_elem['level']] = $xml_elem['tag'];

}

}
if ($xml_elem['type'] == 'complete') {
$start_level = 1;

$php_stmt = '$params';
while($start_level < $xml_elem['level']) {
  $php_stmt .= '[$level['.$start_level.']]';
  $start_level++;
}
$php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
//echo $xml_elem['value'];
eval($php_stmt);?> 

<?php if($i==6){ $i=0;?></tr><tr>
<td><?php echo $xml_elem['value'];?></td>
<?php }else{?> <td><?php echo $xml_elem['value'];?></td> <?php }?>

<? $i++;
}

}?>
</tr>
</table>
<?
echo "<pre>";

print_r ($params);
echo $i."total";
echo "</pre><br>";

?>

<?php
$file = "data.xml";
$depth = array();

function startElement($parser, $name, $attrs)
{
global $depth;
for ($i = 0; $i < $depth[$parser]; $i++) {
echo " ";
}
echo "$name\n";
$depth[$parser]++;
}

function endElement($parser, $name)
{
global $depth;
$depth[$parser]--;
}

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}

while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
?>
