Problem

I have an XML file in this format ``` "note.xml" <currencies> <currency name="US dollar" code_alpha="USD" code_numeric="840" /> <currency name="Euro" code_alpha="EUR" code_numeric="978" /> </currencies> ``` PHP CODE ``` $xml=simplexml_load_file("note.xml"); echo $xml->name. "<br>"; --no output echo $xml->code_alpha. "<br>"; --no output echo $xml->code_numeric . "<br>"; --no output print_r($xml); ``` output of print_r($xml)-->SimpleXMLElement Object ( [currency] => SimpleXMLElement Object ( [@attributes] => Array ( [name] => US dollar [code_alpha] => USD [code_numeric] => 840 ) ) I didnt get any output for the ECHO statements I tried 'simplexml_load_file' and tried reading from it but it doesnt work. Please tell me what php code should I use to read from this format of XML file.
