[RESOLVED] simple xml... casting with a ':' in the node name

[scrupul0us]

I have a node name like:

product:shoes

when i cast it:

echo $xml->channel->item[0]->product:shoes;

i get an error, unexpected ':'

what todo?

[NogDog]

Only work-around I've come up with:

$var = "product:shoes";
echo $xml->channel->item[0]->$var;

[bradgrafelman]

echo $xml->channel->item[0]->{'test:me'}; 

[scrupul0us]

doesnt seem to be working:

<rss>
<channel>
<item>
  <product:price xmlns:domain="http://www.domain.com/">$16.99</product:price>
</item>
</channel>
</rss>

$price = 'product:price';

echo "Price: ". $xml->channel->item->$price;

Can you show us your complete code?

I also hope that the XML code snippet you posted is only a portion of the entire code (e.g. a properly formatted XML document). Can you perhaps show us the rest of this XML document?

[scrupul0us]

adapted my top code to fit the actual xml document:

<?php
$xml = simplexml_load_file("http://www.woot.com/salerss.aspx");

echo "WootOff: ". $xml->channel->item[0]->{'woot:wootoff'} . "<br/>";
echo "WootSold: ". $xml->channel->item[0]->{'woot:soldout'} . "<br/>";
echo "WootQty: ". $xml->channel->item[0]->{'woot:products'}->{'woot:product'} . "<br/>";
echo "WootProduct: ". $xml->channel->item[0]->{'woot:product'} . "<br/>";
echo "WootCondition: ". $xml->channel->item[0]->{'woot:condition'} . "<br/>";
echo "WootPrice: ". $xml->channel->item[0]->{'woot:price'} . "<br/>";
?>

xml:
http://www.woot.com/salerss.aspx

D'oh, I'm stupid.

The 'woot:' means they're using a different namespace... one they've created. As such, you'll need to tell SimpleXML to look in this alternate namespace. Easiest way I can think of would be to use XPath:

$xml = simplexml_load_file("http://www.woot.com/salerss.aspx"); 
$xml->registerXPathNamespace('woot', 'http://www.woot.com/');
$price = $xml->xpath('channel/item[1]/woot:price');

echo $price[0]; // $49.99

[scrupul0us]

how would i get the product quantity?

      <woot:products xmlns:woot="http://www.woot.com/">
        <woot:product quantity="1">Dyson DC07 Cyclonic Bagless Upright Vacuum with Low Reach Attachment</woot:product>
      </woot:products>

i tried:

foreach($xml->xpath('channel/item[1]/woot:products/woot:product') as $a => $b) {
   echo $a,'="',$b,"\"\n";
}

but i get:

0="Dyson DC07 Cyclonic Bagless Upright Vacuum with Low Reach Attachment"

instead of a quantity of 1

[scrupul0us]

i got it:

$wootqty = $xml->xpath('channel/item[1]/woot:products/woot:product/@quantity');

[bradgrafelman]

The code would be:

$xml = simplexml_load_file("http://www.woot.com/salerss.aspx"); 
$xml->registerXPathNamespace('woot', 'http://www.woot.com/'); 
$price = $xml->xpath('channel/item[1]/woot:products[1]/woot:product'); 

$quantity = $price[0]->attributes()->quantity;
$product = $price[0];

EDIT: Heh, didn't see your post before I posted.

[scrupul0us]

yea i struggled with that attributes() function and simply couldnt get it to work

thanks for all the help tho dude

[bradgrafelman]

Definitely understandable... all of this XPath stuff is new to me as well. In fact, I started learning it in resposne to this thread! :p

+1 for intuitive learning
