PHP5 - Getting xml child name via PHP/DOM

hi all,
this is an extract of my big xml file.

<doc>
<y>
<list_type>1</list_type>
<libel> lible 1</libel>
 
</y>
<x>
<list_type>6</list_type>
<libel> lible 2</libel>
 
</x>
<y>
<list_type>3</list_type>
<libel> lible 3</libel>
 
</y>
</doc>

Code (markup):

<doc> is not the root of the document, its one of the root's childs, and also it's not the first child. the question here:
how i can get the name of each child of the node <doc> using PHP/DOM?
how i can also get all the value of each child using PHP/DOM?

thanks

 

You could use a dom parser or something like the following, if regexp is an option:

$pattern = '#<doc>\s*<([a-z]+)>\s*<list_type>(\d+)</list_type>\s*<libel>([^<]+)</libel>\s*</[a-z]+>\s*<([a-z]+)>\s*<list_type>(\d+)</list_type>\s*<libel>([^<]+)</libel>\s*</[a-z]+>\s*\s*<([a-z]+)>\s*<list_type>(\d+)</list_type>\s*<libel>([^<]+)</libel>\s*</[a-z]+>\s*</doc>#si';
if (preg_match_all($pattern, $xml, $matches, PREG_SET_ORDER))
{
        foreach($matches as $m)
        {
                $childName1 = $m[1];
                $listType1  = $m[2];
                $libel1     = $m[3];
 
                $childName2 = $m[4];
                $listType2  = $m[5];
                $libel2     = $m[6];
 
                $childName3 = $m[7];
                $listType3  = $m[8];
                $libel3     = $m[9];
        }
}

Use simplexml, built in to PHP - really easy to use. Here are a few links to get you started:
