[RESOLVED] xml and xpath trouble

[bluto374]

Here is my code, what I am trying to do is return only the models and their siblings that have the <in_stock> set to Yes. I will then write them to a csv file.
I am sure this a simple syntax issue, but I have tried so many time, I am cross-eyed.

<?php

//XML Structure
/*<datafeed>
	<items>
		<item>
			<model>
			<title>
			<price>
			<category>
			<loc>
			<image>
			<description>
			<weight>
			<option_type>
			<option_value>
			<suggest_retail>
			<special_handling>
			<manufacturer>
			<manufacturer_code>
			<packaging>
			<in_stock>
			<last_updated>
		</item>
	<items>
</datafeed>*/
$xml = simplexml_load_file('xrproducts.xml');


for each($xml->xpath('item[in_stock='Yes'+'yes'+'YES']/parent::*') as $output){
	printf('$output'.'<br>');}
fclose($xml);


?>

I got most of this working. I need to be able to write each correct expression to a csv file. I am getting

Warning: fputcsv() expects parameter 2 to be array, boolean given line 34
Here is the updated code.

//XML Structure
/<datafeed>
<items>
<item>
<model>
<title>
<price>
<category>
<loc>
<image>
<description>
<weight>
<option_type>
<option_value>
<suggest_retail>
<special_handling>
<manufacturer>
<manufacturer_code>
<packaging>
<in_stock>
<last_updated>
</item>
<items>
</datafeed>/
$xml = simplexml_load_file('xrproducts.xml');
$with = fopen('inventorywithoptionsactive.txt', 'w');
$without = fopen('inventorywithoutactive.txt', 'w');

foreach ($xml->xpath('//item[in_stock="Yes"]') as $output){
$data = print_r($output->asxml());
fputcsv($with, $data , '|');
}
fclose($with);
fclose($without);

print_r returns true unless you specify that you want to capture output in which case it is returned.
