Hey
Im having a bit of trouble due to creating a media player playlist and using xml to input the directory variables to flash. I haven't really used xml much apart from that.

Anyway...

I need the variables from my XML file in a variable ready to print in php on my website.
If you don't understand have a look at the code and Im sure you will...

playlist.xml

<?xml version="1.0" encoding="utf-8"?>
<PLAYLIST>
<SONG URL="track1.mp3" TITLE="song title 1" ARTIST="artist 1"/>
<SONG URL="track2.mp3" TITLE="song title 2" ARTIST="artist 2"/>
<SONG URL="track3.mp3" TITLE="song title 3" ARTIST="artist 3"/>
</PLAYLIST>

Playlist.php

echo "You currently have * number of songs on your playlist";
echo "<br>";

* I'd like to be able to count the amount of songs in the playlist.. and then print out simple a-href's for each of the files like such:

<a href='SONG URL'>SONG TITLE - SONG ARTIST</a>

Any help here would be greatly appreciated.

Thanks in advanced!

Although I rarely use xml there is a xml reader library and perhaps that will be the key to solving your problem. I haven't used the xml libraries before since I haven't used xml much but hopefully that link should be of some use to you.

Hey
I've managed to get the XML into a php array. But I don't understand how it's structured.
Using this:

print_r($assoc);

I get this output in my browser:

Array ( [0] => Array ( [tag] => PLAYLIST [value] => Array ( [0] => Array ( [tag] => SONG [value] => [attributes] => Array ( [URL] => audio/track1.mp3 [TITLE] => Reece Stanton [ARTIST] => Moonlight in D ) ) [1] => Array ( [tag] => SONG [value] => [attributes] => Array ( [URL] => audio/track2.mp3 [TITLE] => DJ KIDEVA [ARTIST] => Live stage rock - origional ) ) [2] => Array ( [tag] => SONG [value] => [attributes] => Array ( [URL] => audio/track3.mp3 [TITLE] => DJ KIDEVA [ARTIST] => Pop the horn - origional ) ) ) ) )

I need to count how many songs are in the playlist and then print each url link. Any ideas

Thanks

The following will count how many songs:

echo 'There are ';
echo count($array[0]['value']);
echo ' songs.';

Then to display each link use the following

for ($i=0;$i<count($array[0]['value']);$i++) {
echo $array[0]['value'][$i]['attributes']['URL'];
}

Also the styled version of your array output can be viewed with the following.

echo '<xmp>';
print_r($array);
echo '</xmp>';

That will add new lines and spacing.

Thankyou very much :) Works perfectly!

Any idea how I could go around deleting songs or adding another?

Thanks

If you want to make or edit an xml file then you can use the xml writer library. Also if your only updating sections then you can use the str_replace() function.

I've had a read through but I really don't understand. Could you give me some examples to how I should structure this from my php array to deleting a song in the playlist.xml

Thanks

Hi,

I have a similar thread going on a similar note.

If for example, there would only ever be 1 result, in this case 1 player (In my case the player number will be an order id). How could i extract only the order id from the following

<Order id="34343">
   <pricing currency="gbp">
    <price> 23.23 </price>
    </pricing>

</Order>

No ideas :(

Anyone....?

totally forgot id posted this.

I found a solution a few days ago.

If its a single element, something like <Orders><Order>13.45</Order></Orders> you would use $order = $xml->Orders->Order

If its got a few of them, like this <Orders><Order id="123" name="shoes"</Order></Orders> you would use $order = $xml->Orders->Order;
