How to list XML element attributes?

[abdoelmasry]

Hi Friends

i need help to read XML file to an Array using PHP

i have this code xml file:
File name: books.xml

<xml version="1.0" encoding="windows-1256"?>
<books>
<book id="1" name="PHP Book"></book>
<book id="2" name="C# Book"></book> 
<book id="3" name="PatchScripts"></book> 
<book id="4" name="Assemply"></book> 
</books>
 

i wrote this PHP Code to read "books.xml" file:
File Name: xml_reader.php

 
<?php
$xml_hwnd=new domDocument();
$xml_hwnd->Load("books.xml");
$books=$xml_hwnd->getElementsByTagName("book");
$books_array=array();
//Loop to get Elements Contents
foreach($books as $book){
    $bokid=$book->getAttribute("id");
    $bokname=$book->getAttribute("name");
$books_array[$bokid]=array("id"=>$bokid,"name"=>$bokname);
}
// Print Books List
print_r($books_array);
?>
 

the previous code assumes that i know each attribute name,
what about if i don't know attribute name ??
or i have many elements and it's too hard to call every attribute using it's name just like:

$book->getAttribute("id");
$book->getAttribute("name");
$book->getAttribute("author");
$book->getAttribute("etc ...");
 

i need to list all attributes related to any element without mention every element name.

Thanks

you can get a list of attributes by $attlist = $book->attributes;

Thank you very much Dormilich

I did it by the following code:

$attlist = $book->attributes;
foreach($attlist as $attritem){
echo "Attribute Name: ".$attritem->name;
echo "Attribute Value: ".$attritem->value;
}
