[development] trouble destructing xml

[Jamie Holly]

I use SimpleXML pretty much exclusively for this stuff:

$data='<this>
<that parm1="a" parm2="b" parm3="c">red</that>
<that parm1="e" parm2="f" parm3="d">blue</that>
</this>';

$xml=simplexml_load_string($data);
foreach ($xml->that as $item){
  print_r($item);
  echo "<hr>";
}

Returns:

SimpleXMLElement Object ( [@attributes] => Array ( [parm1] => a [parm2]
=> b [parm3] => c ) [0] => red )
------------------------------------------------------------------------
SimpleXMLElement Object ( [@attributes] => Array ( [parm1] => e [parm2]
=> f [parm3] => d ) [0] => blue )

Which is what it should.

You can also use XPath to get at what you want:

$xpath = $xml->xpath('/this/that');

Which would return an array of each <that> item along with the attributes.
