function xmlXpath() 
{ 
    $xml = xmlParse(); 

    $userIN = "cell"; 
    $nodesT = $xml->xpath(" 
     //* 
     [ 
      text() 
      [ 
       contains(
        translate(.,'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 
           'abcdefghjiklmnopqrstuvwxyz'), 
        '".$userIN."' 
       ) 
      ] 
     ] 
    "); 
    return $nodesT; 
}

編輯：考慮您的XPath，做到：

foreach ($nodesT as $nodeT) echo "$nodeT <br />";
