[PHP] PHP 5: SimpleXML attributes
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?
Thanks!

Re: [PHP] PHP 5: SimpleXML attributes
There is a way, but somehow i don't like it though ( but you
can find this in the documentation ):
This is config.xml:
?xml version=1.0 encoding=iso-8859-1 ?
config
lib_error
param name=error_logfile_write type=booleanFALSE/param
/lib_error
/config
And my Testfile:
$xml = simplexml_load_file( 'config.xml' );
foreach ( $xml-lib_error-param AS $id = $param ) {
echo $param['name'] ; // will output 'boolean' !
}

Have you seen Example 4 here: http://us2.php.net/manual/en/ref.simplexml.php
Not sure if that helps or not, though, but it looks like it's already an
associative array.

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!

It certainly looks like an associative array, but the array_keys()
function chokes on it:
Warning: array_keys() [function.array-keys]: The first argument should
be an array in D:\...\test.php on line 5
Explicitely casting it as an array doesn't work either. I guess I want
something like example 4, but without having to hardcode in the
$rating['type']. Something more like:
foreach ($xml-movie[0]-rating as $rating) {
foreach ($rating-attributes() as $key = $value) {
if ($key == 'type') {
switch ($rating['type']) {
...
}
}
}
}
Thanks,

Re: [PHP] PHP 5: SimpleXML attributes
So, this one will work out quite well ( maybe one should take
a look at the documentation of attributes() :-)
foreach ( $xml-lib_error-param AS $param ) {
$n = 0 ;
while ( is_object ( $xml-lib_error-param[$n] ) ) {
foreach( $xml-lib_error-param[$n]-attributes() AS $a = $b ){
echo $a .' -- '. $b .'br';
}
$n++;
}
}

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,

Re: [PHP] PHP 5: SimpleXML attributes
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 :-)
