read xml file with php

Question

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.

Why do you say that simplexml_load_file didn't work? show us your php code first. — STT LCU

never, EVER consult w3schools again. It's often wrong and misleading. — STT LCU

Using DomDocument:

<?php $str = <<<XML <currencies> <currency name="US dollar" code_alpha="USD" code_numeric="840" /> <currency name="Euro" code_alpha="EUR" code_numeric="978" /> </currencies> XML; $dom = new DOMDocument(); $dom->loadXML($str); foreach($dom->getElementsByTagName('currency') as $currency) { echo $currency->getAttribute('name'), "\n"; echo $currency->getAttribute('code_alpha'), "\n"; echo $currency->getAttribute('code_numeric'), "\n"; echo "+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+\n"; } ?>

Using simplexml:

<?php $str = <<<XML <currencies> <currency name="US dollar" code_alpha="USD" code_numeric="840" /> <currency name="Euro" code_alpha="EUR" code_numeric="978" /> </currencies> XML; $currencies = new SimpleXMLElement($str); foreach($currencies as $currency) { echo $currency['name'], "\n"; echo $currency['code_alpha'], "\n"; echo $currency['code_numeric'], "\n"; echo "+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+\n"; } ?>

You can use DomDocument to achieve this objective.

Check on this post http://www.developersnote.com/2013/12/how-to-read-xml-file-in-php.html

$objDOM = new DOMDocument(); //Load xml file into DOMDocument variable $objDOM->load("../configuration.xml"); //Find Tag element "config" and return the element to variable $node $node = $objDOM->getElementsByTagName("config"); //looping if tag config have more than one foreach ($node as $searchNode) { $dbHost = $searchNode->getAttribute('host'); $dbUser = $searchNode->getAttribute('userdb'); $dbPass = $searchNode->getAttribute('dbpass'); $dbDatabase = $searchNode->getAttribute('database'); }
