Re: [PHP] PHP 5: SimpleXML attributes

[Red Wingate]

Guess it was quite luck i saw the little note in the documentation:

Note: SimpleXML has made a rule of adding iterative properties to most 
methods. They cannot be viewed using var_dump() or anything else which 
can examine objects.

Guess i will have to take a look at my config parser again :-)

Wow I can't believe I missed that. Hehe.

I guess the lesson here is don't always trust what you get from print_r().

Thanks for the responses,

foreach ( $xml->lib_error->param AS $param ) {
    $n = 0 ;
    while ( is_object ( $xml->lib_error->param[$n] ) ) {

            echo $a .' --> '. $b .'<br>';
        }
        $n++;

I think you mean that would output 'error_logfile_write'. However, 
what I'm asking is if it's possible to iterate over the SimpleXML 
node attributes 'name' and 'type', without knowing ahead of time that 
'name' and 'type' are expected associative keys. There is an 
attributes() class method, but that just returns a numerically 
indexed array of the attribute values:

Array (
    [0] => 'error_logfile_write',
    [1] => 'boolean'
)
What I want is:

Array (
    ['name'] => 'error_logfile_write',
    ['type'] => 'boolean'
)
Thanks!

Hello,

I have what I hope to be a simple question about SimpleXML. Is it 
possible to get the attributes of a SimpleXML node as an 
associative array?

Consider the following:

<?php
$sxe = simplexml_load_string('<root attr="value"/>');
print_r($sxe->attributes());
// Gives: simplexml_element Object ( [0] => value )
?>
Is there some way to find out that 'value' is the attribute called 
'attr'? In other words, can I iterate over SimpleXML attributes 
without losing track of what their attribute name is? Or is this a 
case where I should switch over to DOM?
