I have XML-file and i try to get value. I need value 12345 from variable media_id. How i can get it with php and simplexml?
<?xml version="1.0" encoding="UTF-8"?>
<Playerdata>
<Clip>
<MediaType>video_episode</MediaType>
<Duration>5400</Duration>
<PassthroughVariables>
<variable name="media_type" value="video_episode"/>
<variable name="media_id" value="12345"/>
</PassthroughVariables>
</Clip>
</Playerdata>
I have now only:
$xml = simplexml_load_file("file.xml");

Answer 1

Try this:
$xml = simplexml_load_file("file.xml");
$variable = $xml->xpath('//variable[#name="media_id"]')[0];
echo $variable["value"];

You can load your XML file into Simplexml which will parse it and return an SimpleXML object.
$xml = simplexml_load_file('path/to/file.xml');
//then you should be able to access the data through objects
$passthrough = $xml->Clip->PassthroughVariables;
//because you have many children in the PassthroughVariables you'll need to iterate
foreach($passthrough as $p){
//to get the attributes of each node you'll have to call attributes() on the object
$attributes = $p->attributes();
//now we can iterate over each attribute
foreach($attributes as $a){
//SimpleXML will assume each data type is a SimpleXMLElement/Node
//so we need to cast it for comparisons
if((String)$a->name == "media_id"){
return (int)$a->value;
}
}
}
The SimpleXMLElement documentation is probably a good starting point when it comes to working with the SimpleXMLObject. http://uk1.php.net/manual/en/class.simplexmlelement.php

Here is w/o Xpath
$xml = simplexml_load_file('file.xml');
$value = (int) $xml->Clip->PassthroughVariables->variable[1]['value'];
