PHP4 XML HELP

[iteach2]

Hi Gurus,

I am using code from yahoo developer network to retrieve/parse the XML below into an Array:

  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
- <SearchResult count="388" xmlns="">
- <products>
- <productSummary id="1010042542">
  <manufacturer sku="45010" name="Elite Image" id="102404" /> 
- <skus>
  <sku val="14111525" type="UNSPSC" /> 
  <sku val="ELI 45010" type="SP Richards Catalog" /> 
  <sku val="SPR45010" type="SP Richards Old" /> 
  <sku val="035255450102" type="UPC" /> 
  <sku val="ELI45010" type="SP Richards" /> 
  <sku val="UNV95200" type="United" /> 
  <sku val="45010" type="MFGPARTNUMBER" /> 
  </skus>
- <descriptions>
  <pd t="3">Letter - 8.5" x 11" - 5000 Sheet - Multipurpose Paper - White</pd> 
  <pd t="2">Elite Image Multipurpose Paper</pd> 
  <pd t="1">Elite Image Multipurpose Paper - Letter - 8.5" x 11" - 5000 Sheet - Multipurpose Paper - White</pd> 
  <pd t="0">Multipurpose Paper, 96 Bright, 20Ib., 8-1/2"x11", White</pd> 
  </descriptions>
  </productSummary>

Here is the yahoo code

// The web service request
$request =  '$url';

$response = file_get_contents($request);

if ($response === false) {
	die('Request failed');
}

// Parse the XML into a DOM tree
$error = null;
if (!$dom = domxml_open_mem($response, DOMXML_LOAD_PARSING, $error)) {
	echo "XML parse error\n";
	foreach ($error as $errorline) {
		// For production use this should be logged to a file instead
		echo $errorline['errormessage']."<br />\n";
		echo " Node  : " . $errorline['nodename'] . "<br />\n";
		echo " Line  : " . $errorline['line'] . "<br />\n";
		echo " Column : " . $errorline['col'] . "<br />\n";
	}
	die('XML parse error');
}


function xml_to_result($dom) {
	$root = $dom->document_element();
	$res['totalResultsAvailable'] = $root->get_attribute('totalResultsAvailable');
	$res['totalResultsReturned'] = $root->get_attribute('totalResultsReturned');
	$res['firstResultPosition'] = $root->get_attribute('firstResultPosition');

	$node = $root->first_child();
	$i = 0;
	$k = null;
	while($node) {
		switch($node->tagname) {
			case 'Result':
				$subnode = $node->first_child();
				while($subnode) {
					$subnodes = $subnode->child_nodes();
					if(!empty($subnodes)) {
						foreach($subnodes as $k=>$n) {
							if(empty($n->tagname)) {
								$res[$i][$subnode->tagname] = trim($n->get_content());
							} else {
								$res[$i][$subnode->tagname][$n->tagname]=trim($n->get_content());
							}
						}
					}
					$subnode = $subnode->next_sibling();
				}
				break;
			default:
				$res[$node->tagname] = trim($node->get_content());
				$i--;
				break;
		}
		$i++;
		$node = $node->next_sibling();
	}
	return $res;
}

$res = xml_to_result($dom);

echo '<pre>';
print_r($res);
echo '</pre>';

The code works, but it does not traverse all the child nodes. It only grabs the <descriptions> out of the<product> tag......Like so...

Array
(
    [totalResultsAvailable] => 388
    [#text] => 
    [products] => Letter - 8.5" x 11" - 5000 Sheet - Multipurpose Paper - White
                Elite Image Multipurpose Paper
                Elite Image Multipurpose Paper - Letter - 8.5" x 11" - 5000 Sheet - Multipurpose Paper - White
                Multipurpose Paper, 96 Bright, 20Ib., 8-1/2"x11", White
            
         
            
                Letter - 8.5" x 11" - 2500 Sheet - Multipurpose Paper - White
                Elite Image Multipurpose Paper
                Elite Image Multipurpose Paper - Letter - 8.5" x 11" - 2500 Sheet - Multipurpose Paper - White
                Multipurpose Paper, 96 Bright, 20Ib., 8-1/2"x11", White
            
        
        
                
            
            
                1" x 2.62" - 3000 Label - Mailing Label - White
                Elite Image White Mailing Laser Label
                Elite Image White Mailing Laser Label - 1" x 2.62" - 3000 Label - Mailing Label - White
                Mailing Label, Laser, 1"x2-5/8", 3000/BX, White
            

            
                2000 Page - Black - Toner Cartridge
                Elite Image Black Toner Cartridge
                Elite Image Black Toner Cartridge - 2000 Page - Black
                Toner Cartridge, 2000 Page Yield, Black
)

I was hoping some could help me to modify the yahoo code to get all the child node....I appreciate "ANY" feedback thank you all. PEACE

i can't help thinking that the built-in function xml_parse_into_struct() might be more useful to you.

<?php
ini_set('error_display', 'on');
error_reporting (E_ALL);
$xml = <<<XML

$p = xml_parser_create();
xml_parse_into_struct($p, $xml, $vals, $index);
echo "<pre>" . print_r($vals, true) . print_r($index, true) . "</pre>";
?>
