xml - XSLT を使用した新しい XML の作成

Question

入力から取得した値を使用して、別の XML に変換しようとしている入力 XML メッセージがあります。それを調べて、サンプルの XSLT を教えてもらえますか?

Answer 1

xsl:template、xsl_value-ofおよびなどの XSL 要素を使用して、XML 要素を反復処理する必要がありますxsl:apply-templates。私はあなたのためにそれをするつもりはありませんが、ここに典型的なスニペットがあります:

<xsl:template match="ConAddress1">
    <street1><xsl:value-of select="."/></street1>
</xsl:template>

ここでは、1 つの要素名から変換し、その内容を選択して新しい要素を作成しています ( street1)。XSL には、約 30 のテンプレートを含めることができます。

チュートリアルを見ると、このタイプの変換の例がたくさんあります。

Answer 2

この変換は、あなたが求めることを行います。基本的に、ルート要素のテンプレートは、出力に表示される順序でソースから要素を選択し、次に汎用テンプレートが各要素をコピー_newして名前に追加します。

他の多くのテンプレートは、他のテンプレートとは異なる方法で処理される要素を処理します。
