将XML转换为PHP多维数组

Question

I have the following array set in an XML file:

<?xml version="1.0"?>
<hats>
    <a id="Chicago BULLS" img="bulls.jpeg" cost="$25.00" />
    <b id="Toronto RAPTORS" img="raptors.jpeg" cost="$25.00" />
    <c id="Orlando MAGIC" img="magic.jpeg" cost="$25.00" />
</hats>
<clothes>
    <a id="Chicago BULLS 23" img="bullstee.jpeg" cost="$30.00" />
    <b id="Toronto RAPTORS 23" img="torontotee.jpeg" cost="$30.00" />
    <c id="Orlando MAGIC 23" img="magictee.jpeg" cost="$30.00" />
</clothes>

I have used a function I found to convert the XML into a Multidimensional Array which looks like this:

Array
(
    [hats] => Array
        (
            [a] => Array
                (
                )

            [a_attr] => Array
                (
                    [id] => Chicago BULLS
                    [img] => bulls.jpeg
                    [cost] => $25.00
                )

            [b] => Array
                (
                )

            [b_attr] => Array
                (
                    [id] => Toronto RAPTORS
                    [img] => raptors.jpeg
                    [cost] => $25.00
                )

            [c] => Array
                (
                )

            [c_attr] => Array
                (
                    [id] => Orlando MAGIC
                    [img] => magic.jpeg
                    [cost] => $25.00
                )

        )

)

As you can see it has only taken half of the XML file, and also I am unable to use numbers so have to resort to letters.

Ultimately I am trying to have it read the XML file then output only what is shown within the tags and tags and eventually more.

How can I parse the XML file cleanly into an array so I can then use a foreach loop to show each line in a given section of the XML file (hats only or clothes only).

You can use xml_parse_into_struct — Parse XML data into an array structure

Syntax: int xml_parse_into_struct ( resource $parser , string $data , array &$values [, array &$index ] ) This function parses an XML string into 2 parallel array structures, one (index) containing pointers to the location of the appropriate values in the values array. These last two parameters must be passed by reference.

 <?php
    $simple = '<hats>
                <a id="Chicago BULLS" img="bulls.jpeg" cost="$25.00" />
                <b id="Toronto RAPTORS" img="raptors.jpeg" cost="$25.00" />
                <c id="Orlando MAGIC" img="magic.jpeg" cost="$25.00" />
            </hats>
            <clothes>
                <a id="Chicago BULLS 23" img="bullstee.jpeg" cost="$30.00" />
                <b id="Toronto RAPTORS 23" img="torontotee.jpeg" cost="$30.00" />
                <c id="Orlando MAGIC 23" img="magictee.jpeg" cost="$30.00" />
            </clothes>';
    $p = xml_parser_create();
    xml_parse_into_struct($p, $simple, $vals, $index);
    xml_parser_free($p);
    echo "Index array
";
    print_r($index);
    echo "
Vals array
";
    print_r($vals);
  ?>
