php - 遍历 simplexml 对象并附加它们

Question

如果这已得到答复，我深表歉意。我一直在寻找解决方案，但找不到任何东西。但是我试图遍历一个我从 API 调用中得到的 simplexml。API 不是最好的，所以当日期超过午夜时，它会完全取消这些订单。因此，为了解决这个问题，我还必须获得第二天的订单，然后对订单进行 foreach，然后在日期执行 if 以获得目标日期。在每个循环中，我希望它获取 simplexml 对象并将其放入变量中并附加每个新对象，这样最后我就有了一个只有正确日期的新对象。

我尝试删除特定节点，但这似乎比在每次迭代结束时合并它们要复杂得多。

if (strtotime($thisFri) >= strtotime($today)) {
    $params = array(
        "shiftStart" => $thisFri . " 00:00:00",
        "shiftEnd" => $thisSat . "12:00:00",
        "status" => "filled"
    );
    $clearConnect->setParameters($params);
    $clearConnect->setResultType('xml');
    $shiftResult = $clearConnect->sendRequest('getOrders'); //gets orders
    $friShifts = simplexml_load_string($shiftResult); //puts the results in to xml
    foreach ($friShifts->order as $shift) { //iterates through each order
        $startLong = new DateTime($shift->shiftStartTime); //figuring out dates
        $start = $startLong->format('Y-m-d');
        $endLong = new DateTime($shift->shiftEndTime);
        $end = $endLong->format('Y-m-d');
        if ($start == $thisFri) { //if to run through all orders with proper start date

这就是我所在的地方。$friShifts 是一个 simplexml，它包含一堆看起来像这样的订单。在此之后发生了更多事情，但这基本上就是我正在寻找的。我希望它将正确日期的每次迭代放入一个新的 simplexml 中，然后通过我的其他函数运行。
