Problem with array result

Hi

I have a problem with this simpleXML class


Original feed looks like this:

Array
(
[id] => http://gdata.youtube.com/feeds/api/videos/5wKsrur81_I/related
[updated] => 2008-05-03T10:16:39.182Z
[category] => Array
(
[@attributes] => Array
(
[scheme] => http://schemas.google.com/g/2005#kind
[term] => http://gdata.youtube.com/schemas/2007#video
)

)

[title] => Videos related to 'b-twist attempt'
[logo] => http://www.youtube.com/img/pic_youtubelogo_123x63.gif
[link] => Array

but in SimpleXML for PHP4 this looks like:

Array
(
[id] => http://gdata.youtube.com/feeds/api/videos/5wKsrur81_I/related
[updated] => 2008-05-03T10:49:41.861Z
[category] => Array
(
[@attributes] => Array
(
[scheme] => http://schemas.google.com/g/2005#kind
[term] => http://gdata.youtube.com/schemas/2007#video
)

)

[title] => Array
(
[@content] => Videos related to \'b-twist attempt\'
[@attributes] => Array
(
[type] => text
)

)

[logo] => http://www.youtube.com/img/pic_youtubelogo_123x63.gif
[link] => Array


Why title is Array in simplexml for php4??

Because the simplexml extension for PHP5 overrides some variables when parsing the XML file. In the original context, as you see here :

<title type="text">Videos related to 'b-twist attempt'</title>

it has an attribute in its tag. And my script does not overrides this.

Maybe this is not the best for some users, but when you expect exact things, this script is better.

How can I fix this ?

If you didn't use the "title" node a lot, you can change your code with $item->title->content() then you can access the title value. If it doesnt work, try $item->title->content()->scalar.

in my test file I have:

<?php
$file = "http://gdata.youtube.com/feeds/api/videos/5wKsrur81_I/related";
$sxml = new simplexml;
$data = $sxml->xml_load_file($file);
echo $item->title->content();
echo '<pre>';
print_r($data);
?>

but I see "Call to a member function on a non-object"

echo $item->title->content();

this is not correct. And I think you don't know what you are doing. Please first learn how to use objects and arrays.

use this:

$item -> title -> {'@content'}

to get the data of 'title' array.

Use this bro!


<?php
$file = "http://gdata.youtube.com/feeds/api/videos/5wKsrur81_I/related";
$sxml = new simplexml;
$data = $sxml->xml_load_file($file);
echo "<br>Related Item to: ".$data -> title -> {'@content'};
echo '<pre>';
print_r($data);
?>

The following example, use RSS from Picasaweb Google API:


=====


<?
require_once "simplexml.class.php";

//if you want to use it as a function;

if(!function_exists("simplexml_load_file")){
function simplexml_load_file($file){
$sx = new simplexml;
return $sx->xml_load_file($file);
}
}

//or directly:

$file = "http://picasaweb.google.com/data/feed/api/user/ahaji2002/album/top?kind=photo";
$sxml = new simplexml;
$data = $sxml->xml_load_file($file);
echo "<pre>";
//print_r($data);
echo "<br>=================Album Properties====================";
echo "<br>Last update: ".$data->updated;

$no_image = $data->{'openSearch:totalResults'};
for ($i = 0; $i < $no_image; $i++){
echo "<br>Item No. ".$i;
