タイプ「汎用参照」のフィールドを持つ内部テーブルのABAPへのXSLT変換

プロローグ



についてのメモは何ですか？ 内部テーブルからのように、その行には未知の（一般化された）タイプ（REF TO DATA）へのリンクが含まれ、実際には同じテーブルへのリンクが格納され、特定の形式のXMLを取得します。 さらに、ネストレベルの数は最初は不明です。

なぜこれが必要ですか？ OLEを使用せずにさまざまなMS Office XMLファイル形式にデータをアップロードするときに、これが必要でした。

このメモは誰のためのものですか？ ABAPのプログラマ向け。

必要な知識レベル： 参照型 、 ジェネリック型 、 XMLとは何かを知るため。 XSLTのようなものがあると聞きます 。



これに対処する方法は？



挑戦する


木があります。 ツリーは内部テーブルに保存されます。 テーブルのタイプは次のように定義されます。 

TYPES : BEGIN OF tdeep_struct , name TYPE string , rf_child_list TYPE REF TO data "    , END OF tdeep_struct , t_deep_struct TYPE STANDARD TABLE OF tdeep_struct WITH NON-UNIQUE DEFAULT KEY .




つまり rf_child_list



フィールドのテーブル行の構造には、ジェネリック型へのリンクが含まれています。



このような構造の内部テーブルから、次の形式のXMLを取得する必要があります。 

 <List> <MyItem> <Name>  </Name> </MyItem> <MyItem> <Name>  </Name> </MyItem> </List>




この場合、結果のXMLのソースツリーのノードの場所は、降順のツリートラバーサルに対応する必要があります（つまり、内部テーブルのレコードを上から表示し始めますrf_child_list



に依存レコードがある場合、最初のレコードの内容を表示します。依存するものがあります-次に、それらを推定します）。



テストケース


次のツリーが内部テーブルに保存されているとします（[名前]フィールドの値がリストされています）： 

 GrandParent1 Child1 Child2 GrandChild1 GrandParent2


タスクの条件に従って、このデータからこのようなXMLを取得する必要があります。

テストケースの最終XML 
 <List> <MyItem> <Name> GrandParent1</Name> </MyItem> <MyItem> <Name>Child1 </Name> </MyItem> <MyItem> <Name>Child2 </Name> </MyItem> <MyItem> <Name>GrandChild1 </Name> </MyItem> <MyItem> <Name> GrandParent2</Name> </MyItem> </List>




解決策


簡単なものから始めましょう：ABAPコード、もっと簡単なものは何ですか？



内部テーブルにテストデータを定義して記入する 
 DATA : gt_tree TYPE t_deep_struct "  , gtree TYPE tdeep_struct "     , gchild TYPE tdeep_struct "     , ggrandchild TYPE tdeep_struct "     . FIELD-SYMBOLS : <gt_child_list> TYPE t_deep_struct "     , <gt_grandchild_list> TYPE t_deep_struct "     . START-OF-SELECTION. gtree-name = 'GrandParent1'. CREATE DATA gtree-rf_child_list TYPE t_deep_struct. ASSIGN gtree-rf_child_list->* TO <gt_child_list>. gchild-name = 'Child1'. APPEND gchild TO <gt_child_list>. gchild-name = 'Child2'. CREATE DATA gchild-rf_child_list TYPE t_deep_struct. ASSIGN gchild-rf_child_list->* TO <gt_grandchild_list>. ggrandchild-name = 'GrandChild1'. APPEND ggrandchild TO <gt_grandchild_list>. APPEND gchild TO <gt_child_list>. APPEND gtree TO gt_tree. CLEAR gtree. gtree-name = 'GrandParent2'. APPEND gtree TO gt_tree.






問題を解決して、XSLT変換を使用する必要があると考えました。 このメモのタグは「初心者向けXSLT」だったので、それが何であるかを言及する必要があります。 あなたの指ですべての場合、これは1つのXMLから別のXMLを取得できるようにするような言語です。 ただし、XSLT自体はXMLのサブセットです。 やめて！ 内部テーブルは、XMLを変換する場合、どこで使用されますか？ これは、SAPでのXSLT実装のこのような機能です。 もっと詳しく見てみましょう。



ABAPの変換演算子は、 CALL TRANSFORMATIONステートメントを担当します。 多くのオプションと多くの作業オプションがあります。

SOURCE _ = __



指定して、変換が必要な入力データを送信します。

結果は、 RESULT XML XML/ //



指定することで取得できRESULT XML XML/ //



。 簡単にするために、結果を文字列で取得します。



CL_XML_DOCUMENTオブジェクトの標準手段を使用して、画面に変換の結果を表示します。

次のコードを取得します。 

  CALL TRANSFORMATION zedu_test_xslt_deep_transform2 SOURCE table = gt_tree RESULT XML gxml_str. go_xml_doc->parse_string( gxml_str ). go_xml_doc->display( ).




そうそう...私は気が散っている！ 問題は、1つのXMLを別のXMLに変換するための変換である場合、変換はそれと何の関係があるのでしょうか？



ビットRTFM


まず、SAPは変換を使用してデータをシリアル化および逆シリアル化します。 つまり、データオブジェクト（構造、内部テーブル、オブジェクト）から、ビットシーケンスの形式で表現を取得する方法、およびその逆。 シリアル化のタスクのみがあります。入力はネストされた構造（内部ABAPテーブル）であり、出力はXML（テキスト表現）です。

SAPには2種類のXSLTがあります。通常のXSLTと単純な変換（ST）です。 SAPは小さなXSLTのようであり、彼はXSLTのサブセットを実装しました。 私たちには合わない 入力パラメーターのジェネリック型フィールドを使用することはできません。

純粋なXSLTのままです。

SAPは、XSLTを使用してシリアル化を実行するときに、入力変換パラメーターをasXML（ 標準XML表現 ）形式に変換します。 この変換のプロセスでは、 特定のルールに従って 、ABAP型が変換されます。これはジェネリック型にも適用されます（ 予約名IDを使用したABAP XSLTの標準変換を使用して、変数の正規表現を明示的に取得できます ）。

変換中のデータ変換を説明するABAPヘルプイメージ

シリアル化の方向に興味があります



私の例では、正規のXML表現は次のとおりです。 
 <?xml version="1.0" encoding="utf-8" ?> <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0"> <asx:values> <TABLE> <item> <NAME>GrandParent1</NAME> <RF_CHILD_LIST href="#d1" /> </item> <item> <NAME>GrandParent2</NAME> <RF_CHILD_LIST /> </item> </TABLE> </asx:values> <asx:heap xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:abap="http://www.sap.com/abapxml/types/built-in" xmlns:cls="http://www.sap.com/abapxml/classes/global" xmlns:dic="http://www.sap.com/abapxml/types/dictionary"> <prg:T_DEEP_STRUCT id="d1" xmlns:prg="http://www.sap.com/abapxml/types/program/ZEDU_TEST_XSLT_DEEP_TRANSFORM"> <item> <NAME>Child1</NAME> <RF_CHILD_LIST /> </item> <item> <NAME>Child2</NAME> <RF_CHILD_LIST href="#d2" /> </item> </prg:T_DEEP_STRUCT> <prg:T_DEEP_STRUCT id="d2" xmlns:prg="http://www.sap.com/abapxml/types/program/ZEDU_TEST_XSLT_DEEP_TRANSFORM"> <item> <NAME>GrandChild1</NAME> <RF_CHILD_LIST /> </item> </prg:T_DEEP_STRUCT> </asx:heap> </asx:abap>
