Starting with XML

[leam hall]

I'm trying to work on an XML document and turn it into something I can put
into a database or array. Am getting stuck as I try to learn the PHP stuff
needed for XML.

What I have so far is just:

$xml = simplexml_load_file('my-file.xml');

$status = $xml->status;
echo "status is $status.\n";

$href = $xml->reference->href;
echo "href is $href.\n";

Which gives:

status is accepted.
href is .


If I do:

print_r($xml);

It starts out with:

SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => My_Info
)

[status] => accepted
[title] => Nice long string title
[reference] => SimpleXMLElement Object
(
[@attributes] => Array
(
[href] => http://www.example.com
)

)



How do I reference the nested objects? The file is fairly long and seems
deeply nested.

Thanks!

The value you’re trying to retrieve is an attribute, and can be accessed using the attributes method: http://php.net/simplexmlelement.attributes

Stuart, thanks for the help so far. I'm diving into the next issue.

#####
Here's a bit from var_dump:

[Group] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => V-756
)

[title] => IDTAG111223
[description] => <GroupDescription></GroupDescription>
[Rule] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => Local_tag_rule
[severity] => medium
[weight] => 10.0
)
#####

The line that fails:

$ruleAttributes =
simplexml_load_string($group->Rule->attributes['severity']);

#####

However, this works:
foreach($group->Rule->attributes() as $k => $v){
echo $k . " => " . $v;
}

#####

The issue is that I just need one value out of the attributes array. I do
not know the purpose of the "@" in [@attributes]

Suggestions?
