Xml jqgrid（邻接）中带json的treegrid，jqgrid不带json显示数据？

我很难找到如何将这个xml转换成json的例子，用于jqgrid的邻接模型，xml是可以工作的，但是在文档中没有json的例子，所以有人能指导我将这个xml转换成json吗？？？，我还在想办法，真的很感谢你的帮助

这是我的代码：

if ( stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml") ) {
        header("Content-type: application/xhtml+xml;charset=utf-8"); } else {
        header("Content-type: text/xml;charset=utf-8");
}
if(isset($_REQUEST['nodeid'])==FALSE) {
    $node =0;
}
else{
    $node = (integer)$_REQUEST["nodeid"];
}
$clsJqGrid = new redCuidadana();
$et = ">";
echo "<?xml version='1.0' encoding='utf-8'?$et\n";
echo "<rows>";
echo "<page>1</page>";
echo "<total>1</total>";
echo "<records>1</records>";

if($node >0) { //check to see which node to load
   $wh = 'parent_id='.$node; // parents
   //$n_lvl = $n_lvl+1; // we should ouput next level
} else {
   //$wh = 'ISNULL(parent_id)'; 
   $wh ='parent_id=0';// roots
}
$mostrarRegistros= $clsJqGrid->mostrarRegistros($wh);
foreach ($mostrarRegistros as $row){
   echo "<row>";         
   echo "<cell>".$row["id_ciudadano"]."</cell>";
   echo "<cell>".$row["distrito"]."</cell>";
   echo "<cell>".$row["seccion"]."</cell>";
   echo "<cell>".$row["rol"]."</cell>";
   echo "<cell>".$row["clave_electoral"]."</cell>";
   echo "<cell>".$row["nombre"]."</cell>";
   echo "<cell>".$row["apaterno"]."</cell>";
   echo "<cell>".$row["amaterno"]."</cell>";
   echo "<cell>".$row["level"]."</cell>";
   echo "<cell><![CDATA[".$row["parent_id"]."]]></cell>";
   if($row["level"] == "2"){echo "<cell>"."true"."</cell>";}
   else{echo "<cell>".$row["isLeaf"]."</cell>";}
   echo "<cell>".$row["expanded"]."</cell>";
   echo "</row>";
}
echo "</rows>";
?>

我不懂php，但我在c#（ASP.NET MVC3）中就是这样做的：这是用于自动加载树，而不是立即加载树

行动方法：

public JsonResult GetSPTreeJSON(string nodeid, string n_level, string currentUser)
        {
            List<TreeNode> list = _clientService.GetTreeNodeList(nodeid, n_level);

            var jsonData = new
            {
                page = 1,
                total = 1,
                records = 1,
                rows = (
                    from TreeNode u in list
                    select new
                    {
                        cell = new object[] { u.Id.ToString(), u.name, u.level, u.ParentId, u.isLeaf, false }
                    }).ToList()
            };

            return Json(jsonData, JsonRequestBehavior.AllowGet);

        }

示例JSON（注意我们的ID是GUID）：

也许您可以轻松转换。

如果您有任何问题，请告诉我
