My parser:

<?php        
if (isset($_GET['formSubmit'])) {
$option = $_GET['option'];
$option = array_values($option);
if (!empty($option)){
	$xml = simplexml_load_file('differences.xml');
	$i = 0;
	$count = count($option); ?>
<table>
<tr>
	<td>Item</td>
        <td>Code</td>
        <td>Type</td>
        <td>Level</td>
    </tr>
<?php
	while($i < $count)
		{
			$selected = $xml->xpath("//item[contains(@name,'".$option[$i]."')]");
			echo "<tr>";
			echo "<td>".$selected[0]['name']."</td>";
			echo "<td>".$selected[0]['code']."</td>";
			echo "<td>".$selected[0]['type']."</td>";
			echo "<td>".$selected[0]['requiredLevel']."</td>";
			echo "</tr>";
			$i++;
		} ?>
</table>

 

This works great however requiredLevel is showing nothing. Here is what is stored in the $selected array:

 

Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [buildingName] => EiffelTower [code] => lM [type] => building ) [requiredLevel] => 5 [cost] => 5000 [built] => 03/31/1889  => SimpleXMLElement Object ( [@attributes] => Array ( [itemClass] => EiffelTower_construct ) ) [defaultItem] => SimpleXMLElement Object ( [@attributes] => Array ( [amount] => 1 [name] => iron ) ) [finishedReward] => iron [image] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [loadClass] => mc [name] => construct_0 [url] => /buildings/eiffel_tower.swf ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [loadClass] => mc [name] => construct_1 [url] => /buildings/eiffel_tower.swf ) ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [loadClass] => mc [name] => built_0 [url] => /buildings/eiffel_tower.swf ) ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [name] => icon [url] => buildings/eiffel_tower.png ) ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [name] => startIcon [url] => /buildings/eiffel_tower.png ) ) [5] => SimpleXMLElement Object ( [@attributes] => Array ( [name] => halfIcon [url] => /buildings/eiffel_tower.png ) ) [6] => SimpleXMLElement Object ( [@attributes] => Array ( [name] => completeIcon [url] => /buildings/eiffel_tower.png ) ) ) [constructionUI] => /buildings/Construct_eiffel_tower.swf [countryCard] => france )

 

My XML:

 

		<element>
			<item code="lM" name="snowman2010" type="building">
				<requiredLevel>5</requiredLevel>
				<cost>5000</cost>
				<built>03/31/1889</built>
				<storageType itemClass="EiffelTower_construct"/>
				<defaultItem amount="1" name="iron"/>
				<finishedReward>iron</finishedReward>
				<image loadClass="mc" name="construct_0" url="/buildings/eiffel_tower.swf"/>
				<image loadClass="mc" name="construct_1" url="/buildings/eiffel_tower.swf"/>
				<image loadClass="mc" name="built_0" url="/buildings/eiffel_tower.swf"/>
				<image name="icon" url="/buildings/eiffel_tower.png"/>
				<image name="startIcon" url="/buildings/eiffel_tower.png"/>
				<image name="halfIcon" url="/buildings/eiffel_tower.png"/>
				<image name="completeIcon" url="/buildings/eiffel_tower.png"/>
				<constructionUI>/buildings/eiffel_tower.swf</constructionUI>
				<countryCard>france</countryCard>
			</item>

 

Using the established code pattern in my parser.php how can I print out requiredLevel?

 

The output of my array is mighty confusing! [/code]

[mcfmullen]

Can anyone help me decode my array?

 

It completely baffles me what with the brackets and SimpleXMLElement Objects.

 

I can't find any resources written in plain english to help explain it nor can I find any resources to extract the information.

 

For example, how can I echo [requiredLevel] or [finishedReward] or icon

 

Any help would be GREATLY appreciated!

[mcfmullen]

echo "<td>".$selected[0]['requiredLevel']."</td>";
echo "<td>".$selected['requiredLevel']."</td>";
echo "<td>".$selected[0][0]['requiredLevel']."</td>";

 

None of the above work. Any other suggestions?
