xml - この XSLT 除去変換を異なるノードの親に対してのみ機能させるにはどうすればよいですか?

Question

XSLT:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="*[*][deep-equal(.,preceding::*[name()=current()/name()][@id=current()/@id][1])]"/>
</xsl:stylesheet>

私の入力に適用されたとき：

<myroot>
    <nodeA id="a">
        <section id="i">  
            <item1 id="0" method="create"> 
                <somechild>a</somechild>
            </item1>

            <item1 id="1" method="create">
                <otherchild>a</otherchild>
            </item1>
        </section>        

        <section id="i">
            <item1 id="0" method="create"> <!-- second consecutive create, we will remove this -->
                <somechild>a</somechild>
            </item1>
            <item1 id="0" method="create"> <!-- third consecutive create, BUT children have different value , so we don't remove this -->
                <somechild>bbb</somechild>
            </item1>
            <item1 id="3" method="create">
                <other>xx</other>    
            </item1>

            <item1 id="0" method="change"> 
                <otherchild>a</otherchild>
            </item1>
            <item1 id="0" method="change"> <!-- second consecutive create, we will remove this -->
                <otherchild>a</otherchild>
            </item1>
        </section>
    </nodeA>
</myroot>

正しい出力を教えてください：

<myroot>
    <nodeA id="a">
        <section id="i">  
            <item1 id="0" method="create"> 
                <somechild>a</somechild>
            </item1>

            <item1 id="1" method="create">
                <otherchild>a</otherchild>
            </item1>
        </section>        

        <section id="i">
            <item1 id="0" method="create"> <!-- third consecutive create, BUT children have different value , so we don't remove this -->
                <somechild>bbb</somechild>
            </item1>
            <item1 id="3" method="create">
                <other>xx</other>    
            </item1>

            <item1 id="0" method="change"> 
                <otherchild>a</otherchild>
            </item1>
        </section>
    </nodeA>
</myroot>

*しかし、問題は、別のnodeAノードidがある場合、これら2つのノードを1つとして扱うことです*

2 番目の入力例:

<myroot>
    <nodeA id="a">
        <section id="i">  
            <item1 id="0" method="create"> 
                <somechild>a</somechild>
            </item1>

            <item1 id="1" method="create">
                <otherchild>a</otherchild>
            </item1>
        </section>        

        <section id="i">
            <item1 id="0" method="create"> <!-- second consecutive create, we will remove this -->
                <somechild>a</somechild>
            </item1>
            <item1 id="0" method="create"> <!-- third consecutive create, BUT children have different value , so we don't remove this -->
                <somechild>bbb</somechild>
            </item1>
            <item1 id="3" method="create">
                <other>xx</other>    
            </item1>

            <item1 id="0" method="change"> 
                <otherchild>a</otherchild>
            </item1>
            <item1 id="0" method="change"> <!-- second consecutive create, we will remove this -->
                <otherchild>a</otherchild>
            </item1>
        </section>
    </nodeA>

    <nodeA id="b">
        <section id="i">  
            <item1 id="0" method="create"> 
                <somechild>a</somechild>
            </item1>

            <item1 id="1" method="create">
                <otherchild>a</otherchild>
            </item1>
        </section>        

        <section id="i">
            <item1 id="0" method="create"> <!-- second consecutive create, we will remove this -->
                <somechild>a</somechild>
            </item1>
            <item1 id="0" method="create"> <!-- third consecutive create, BUT children have different value , so we don't remove this -->
                <somechild>bbb</somechild>
            </item1>
            <item1 id="3" method="create">
                <other>xx</other>    
            </item1>

            <item1 id="0" method="change"> 
                <otherchild>a</otherchild>
            </item1>
            <item1 id="0" method="change"> <!-- second consecutive create, we will remove this -->
                <otherchild>a</otherchild>
            </item1>
        </section>
    </nodeA>
</myroot>

私の出力：

<myroot>
   <nodeA id="a">
      <section id="i">
         <item1 id="0" method="create">
            <somechild>a</somechild>
         </item1>
         <item1 id="1" method="create">
            <otherchild>a</otherchild>
         </item1>
      </section>
      <section id="i">
         <item1 id="0" method="create"><!-- third consecutive create, BUT children have different value , so we don't remove this --><somechild>bbb</somechild>
         </item1>
         <item1 id="3" method="create">
            <other>xx</other>
         </item1>
         <item1 id="0" method="change">

      </section>
   </nodeA>
   <nodeA id="b">
      <section id="i">

2 つ以上のノードの親などに対して機能させるには、XSLT ファイルに何を追加する必要がありますnodeAか。nodeB

• successive duplicate目的は、同じ要素名item1 item2など、同じidと同じでノードを削除することですmethod。

• same element name正確な、same id、same methodおよびを含む他のノードが続く XML ノードは、same children重複していると見なされます。

• 比較されている 2 つのノードが同じ「nodeA」レベルのノードを共有していない場合、それらは削除される重複と見なされるべきではありません。

この変換:

    xmlns:xs="http://www.w3.org/2001/XMLSchema">

 <xsl:template match="node()|@*">

提供された XML ドキュメントに適用した場合:
