XSLファイルのノードが繰り返されていないFor-Eachループ

Question

したがって、私はこのXMLファイル（下記）を持っており、CustomerごとにReservationsのリストを作成しようとしています。お客様はReservationsの「内部」で、一意ではないため（複数のお客様が異なる予約を行うことができます）、私は問題に直面しています。ReservationsをCustomerごとに取得できますが、私がすべての時間Reservationsを投げ捨てて行くので、ファイル。

あなたは、どうすればいいですか？すでに処理されているCustomersというHTMLファイルには送信しないでください。

私たちが必要とする最後のものは、Muenchianグループのもう一つの例です。あなたが自分で管理するのに見えることはできませんので、しかし、それをこのようにしてみてください：
