i've got an id attribute value for an element.

i want to select only its children (not all descendants).

i used $childElements = $xml->xpath('//entity[@id=212323]'); print_r($childElements);

but that would select ALL descendants and print them out. i just want to select the 1 generation children. how could i do that?

<entity id=212323>
    <this>asd</this>
    <this>asd</this>
    <this>asd</this>
    <this>
        <notThis>asd</notThis>
        <notThis>asd</notThis>
        <notThis>asd</notThis>
    </this>
</entity>
