SimpleXMLElement::attributes

It is really simple to access attributes using array form. However, you must convert them to strings or ints if you plan on passing the values to functions.<?phpSimpleXMLElement Object(    [@attributes] => Array        (            [id] => 55555        )    [text] => "hello world")?>Then using a function<?phpfunction xml_attribute($object, $attribute){    if(isset($object[$attribute]))        return (string) $object[$attribute];}?>I can get the "id" like this<?phpprint xml_attribute($xml, 'id'); //prints "55555"?>

Note that you must provide the namespace if you want to access an attribute of a non-default namespace:Consider the following example:<?php$xml = <<<XML<?xml version="1.0"?><Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"> <Table Foo="Bar" ss:ExpandedColumnCount="7"> </Table></Workbook>XML;$sxml = new SimpleXMLElement($xml);/** * Access attribute of default namespace */var_dump((string) $sxml->Table[0]['Foo']);// outputs: 'Bar'/** * Access attribute of non-default namespace */var_dump((int) $sxml->Table[0]['ExpandedColumnCount']);// outputs: 0var_dump((int) $sxml->Table[0]->attributes('ss', TRUE)->ExpandedColumnCount);// outputs: '7'?>

<?php$att = 'attribueName';// You can access an element's attribute just like this :$attribute = $element->attributes()->$att;// This will save the value of the attribute, and not the objet$attribute = (string)$element->attributes()->$att;// You also can edit it this way :$element->attributes()->$att = 'New value of the attribute';?>

Tip to get a real array of all attributes of a node (not SimpleXML's object acting like an array)<?php//- $node is a SimpleXMLElement object$atts_object = $node->attributes(); //- get all attributes, this is not a real array$atts_array = (array) $atts_object; //- typecast to an array//- grab the value of '@attributes' key, which contains the array your after$atts_array = $atts_array['@attributes'];var_dump($atts_object); //- outputs object(SimpleXMLElement)[19]                        //-             public '@attributes' => ...var_dump($atts_array); //- outputs array (size=11) ...?>Hope this helps!

Easiest and safest way to get attributes as an array is to use the iterator_to_array function (see http://php.net/manual/en/function.iterator-to-array.php):<?php      $x = new SimpleXMLElement('<div class="myclass" id="myid"/>');      $attributes = iterator_to_array($x->attributes());?>

Use attributes to display when it meets certain condition defined attribute / value in xml tags.Use atributos para exibir quando atende determinada condição definida atributo / valor em tags XML.Consider the following example:Considere o seguinte exemplo:(file.xml)<?xml version="1.0" encoding="UTF-8"?><list>    <item type="Language">        <name>PHP</name>        <link>www.php.net</link>    </item>    <item type="Database">        <name>Java</name>        <link>www.oracle.com/br/technologies/java/‎</link>    </item></list>Checks if the attribute value equals "Language", if equal prints everything that is related to "Language".Verifica se o valor do atributo é igual a "Language", se for, imprime tudo o que for relativo ao mesmo.<?php$xml = simplexml_load_file("file.xml");foreach($xml->children() as $child) {            $role = $child->attributes();        foreach($child as $key => $value) {                        if($role == "Language")            echo("[".$key ."] ".$value . "<br />");                    }}?>output:saída:[name] PHP[link] www.php.net
