Printing XML node attributes with XPath

[lol768]

I'm using XPath to parse an XML file. Instead of printing out the elements value I want to print out an attribute. For example:

<users>

<moderators>
<user1 postcount="50">
<permissions>
<editposts>true</editposts>
<deleteposts>true</deleteposts>
</permissions
</user1>
</moderators>

<standard_users>
<user2 postcount="21">
<permissions>
<editposts>false</editposts>
<deleteposts>false</deleteposts>
</permissions
</user2>

<user3 postcount="32">
<permissions>
<editposts>false</editposts>
<deleteposts>false</deleteposts>
</permissions
</user3>

<user4 postcount="13">
<permissions>
<editposts>false</editposts>
<deleteposts>false</deleteposts>
</permissions
</user4>
</standard_users>

</users>

So in terms of the code above I want to use an XPath query (/users/standard_users/*) and print out the post count for all the standard users. At the moment I can use a foreach loop to get the nodes inside the user block ($n->textContent) but is there a way to print out the attributes of a specific element (postcount = "13").

I hope the above makes sense, if not please tell me and I'll attempt to clarify the post.

Thanks

I've tried adding the @attribute to the XPath query but I'm getting a PHP error: DOMXPath::query(): Invalid expression in /home/lol768/midi_test/test1.php on line 11

Here's the PHP code (I'm parsing an converted MIDI file)

<?php
//Init XPath
$dom = new DomDocument();
$dom -> load("file.xml"); //Load file

$xp = new DomXPath($dom);

$notes = $xp -> query("/MIDIFile/Track[2]/Event/NoteOn@Note"); //Parse XML for NoteOn events

foreach ($notes as $n)
{
	echo ($n->textContent . "\n");
}

?>

Each Note on event appears like this:
<NoteOn Channel="6" Note="68" Velocity="120"/>

To get all the postcount attributes from your posted XML the expression would be this:

/users/standard_users/*/@postcount

From that you can probably see what needs doing in your code.

Thanks for your help 🙂. I'll try it and mark the thread solved.
