PHP SimpleXML and Variables Help

[TheZach]

I am trying to find out how to merge the FIPS part of this XML file into one php variable with SimpleXML.

 

a sample xml file I'm trying to use is at http://server1.thezach.net/examplewarn.xml

 

basically i want a variable with "001033,001077" in it (without the quotes)

 

I'm new to PHP and this is my first time using this forum so please forgive me if I'm full of fail

does this point you in the right direction?

<?php
$xml_feed="http://server1.thezach.net/examplewarn.xml";
if($xml = simplexml_load_file("$xml_feed")){
foreach($xml->info->area->geocode as $number){
$value=$number->value;
echo"value = $value<br />\n";
    }
}
?>
