XML（XMLバージョン1）をアンマーシャリングして値を取得し、それらのXMLの新しいバージョンに入れなければなりません（XMLバージョン2）。問題は、xsiのタグがたくさんあることです。この事実は、非マーシャリングされたクラスに、さまざまなクラスで拡張できる抽象クラスとして反映されています。私の質問は、 XML xsi：typeによって与えられた抽象クラス？私はここに私のコードとリソース、おかげで置いた。データとhttp://www.datex2.eu/content /xml-schemaXMLを抽象クラスにアンマーシャリングする方法、クラスをインスタンス化するためにxsi：typeを知る方法
XMLソース：実際のバージョンのhttp://infocar.dgt.es/datex2/dgt/SituationPublication/all/content.xml
XMLスキーマ：http://www.datex2.eu/content/datex-ii-xml-schema-23私finallが達成最初に変換することである私が欲しいデータがコンテンツ
XMLスキーマこれの1つでXML
私の実際のコード（テスト）：
