SimpleXML Won't Parse...

[Ark3typ3]

So I have had this work with other XML documents, but it won't work on the current one.

I load the xml file into a variable, I then use a foreach to load the specific values into an array and then I use the array to display prices from the XML document later in the script. As I said...it works on other scripts but I need to know what I'm doing wrong for this specific XML document.

//Extract price data from marketstatfuel_xml.xml
$arr = array();
$xml = simplexml_load_file("marketstatfuel_xml.xml");
$i=0;

foreach($xml->evec_api->marketstat->type as $child){ 
 $arr[$i]="{$child->sell->avg}";
 $i=$i+1;
}

and here's a small sample of the xml:

<!-- This is the new API :-) --> 



<evec_api version="2.0" method="marketstat_xml"> 
<marketstat>

  </sell> 
</type> 

</marketstat> 
</evec_api> 

I'm not sure if the stuff at the top of the xml document is messing it up though...

Warning: Invalid argument supplied for foreach() in /homepages/4/d312038315/htdocs/leaf/bmtracker/fuel-calc.php on line 132

That's the error I receive with it.

You don't need the "evec_api->". This worked for me:

<pre><?php
//Extract price data from marketstatfuel_xml.xml
$arr = array();
$xml = simplexml_load_file("marketstatfuel_xml.xml");
foreach($xml->marketstat->type as $child) {
   $arr[] = "{$child->sell->avg}";
}
print_r($arr);
?></pre>

Great! thanks a bunch, that worked like a charm....strange that I didn't need evec_api, but I'll take it.
