Sort XML Files

[mikeh]

Could anyone give me some pointers on how to sort an array of xml files by a node.

I am trying to find all the files in a 'products' directory and display the results as description, pic, price etc.. I have accomplished that, but I need them sorted by price.

I'm interested in this as well. Can you give an example excerpt from the array?

Could anyone give me some pointers on how to sort an array of xml files by a node.

I am trying to find all the files in a 'products' directory and display the results as description, pic, price etc.. I have accomplished that, but I need them sorted by price.

Here is a sample code for reading product files and sorting them by price and name:

Code:

function myplugin_compare_price($a, $b) {
  $result = $a['price'] - $b['price']; // sort by price - or $b['price'] - $a['price']
  return $result == 0 ? strcmp($a['name'],$b['name']) : $result; // sort by name if same price
}

// read product files into array $products:
$products = array();
$productdir = 'path/to/dir/';
$dir_handle = @opendir($productdir);
while ($filename = readdir($dir_handle)) {
  if (strrpos($filename,'.xml') === strlen($filename)-4) {
    $data = getXML($productdir . $filename);
    $products[] = array('name' => (string) $data->name, 'price' => (int) $data->price, ...);
  }
}
// sort by user function:
usort($products, 'myplugin_compare_price');

That did the trick
Thanks!
