根據起始元素對兄弟組進行分組

Question

輸入xml包含不同裝運的多個重複記錄。 記錄1,2和3屬於一次裝運，記錄1,2和3屬於另一批貨物。 輸出應該像輸出xml。每批貨物都被轉換爲Root-Element。

輸入：

<?xml version = '1.0' encoding = 'UTF-8'?> 
    <Root-Element> 

      <RECORD1> 
      <C2>500000000222725718846C </C2> 
      <C3>3014 </C3> 
      <C4> DELVRY02 </C4> 
      </RECORD1> 
      <RECORD2> 
      <C2> 50000000022272571880</C2> 
      <C3>000010000000200</C3> 
      <C4>9659666341109001 </C4> 
      </RECORD2> 
      <RECORD3> 
      <C2> 50000000022272</C2> 
      <C3>5718800000</C3> 
      <C4>200000103002</C4> 
      </RECORD3> 


     <RECORD1> 
      <C2>5000000002227ABCD </C2> 
      <C3>3014 </C3> 
      <C4> DELVRY02 </C4> 
      </RECORD1> 
      <RECORD2> 
      <C2> 50000000022272571880</C2> 
      <C3>000010000000200</C3> 
      <C4>9659666341109001 </C4> 
      </RECORD2> 
      <RECORD3> 
      <C2> 50000000022272</C2> 
      <C3>5718800000</C3> 
      <C4>200000103002</C4> 
      </RECORD3> 

    </Root-Element> 

輸出：

<?xml version="1.0"?> 
<Root-Element> 
<shipment> 
<RECORD1> 
<C2>500000000222725718846C </C2> 
<C3>3014 </C3> 
<C4> DELVRY02 </C4> 
</RECORD1> 
<RECORD2> 
<C2> 50000000022272571880</C2> 
<C3>000010000000200</C3> 
<C4>9659666341109001 </C4> 
</RECORD2> 
<RECORD3> 
<C2> 50000000022272</C2> 
<C3>5718800000</C3> 
<C4>200000103002</C4> 
</RECORD3> 
</shipment> 
<shipment> 
<RECORD1> 
<C2>5000000002227ABCD </C2> 
<C3>3014 </C3> 
<C4> DELVRY02 </C4> 
</RECORD1> 
<RECORD2> 
<C2> 50000000022272571880</C2> 
<C3>000010000000200</C3> 
<C4>9659666341109001 </C4> 
</RECORD2> 
<RECORD3> 
<C2> 50000000022272</C2> 
<C3>5718800000</C3> 
<C4>200000103002</C4> 
</RECORD3> 
</shipment> 
</Root-Element> 

我想這下面XSLT，但它給一個問題。

XSLT：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="xml" indent="yes"/> 
    <xsl:key name="items" match="Root-Element/*" 
      use="generate-id(preceding-sibling::RECORD1[1])"/> 
    <xsl:template match="/Root-Element"> 
    <Root-Element> 
     <xsl:apply-templates select="@*"/> 
     <xsl:apply-templates select="RECORD1"/> 
    </Root-Element> 
    </xsl:template> 
    <xsl:template match="RECORD1"> 
    <shipment> 
     <xsl:copy-of select="."/> 
     <xsl:copy-of select="key('items', generate-id())"/> 
    </shipment> 
    </xsl:template> 

</xsl:stylesheet> 

輸出與上面的XSLT越來越：

<?xml version="1.0"?> 
<Root-Element> 
<shipment> 
<RECORD1> 
<C2>500000000222725718846C </C2> 
<C3>3014 </C3> 
<C4> DELVRY02 </C4> 
</RECORD1> 
<RECORD2> 
<C2> 50000000022272571880</C2> 
<C3>000010000000200</C3> 
<C4>9659666341109001 </C4> 
</RECORD2> 
<RECORD3> 
<C2> 50000000022272</C2> 
<C3>5718800000</C3> 
<C4>200000103002</C4> 
</RECORD3> 
<RECORD1><!-- it should not come....This is the issue --> 
<C2>5000000002227ABCD </C2> 
<C3>3014 </C3> 
<C4> DELVRY02 </C4> 
</RECORD1>

Answer 1

我相信這你想要做什麼：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="xml" indent="yes"/> 
    <xsl:key name="items" match="Root-Element/*[name() != 'RECORD1']" 
      use="preceding-sibling::RECORD1[1]"/> 
    <xsl:template match="/Root-Element"> 
    <Root-Element> 
     <xsl:apply-templates select="@*"/> 
     <xsl:apply-templates select="RECORD1"/> 
    </Root-Element> 
    </xsl:template> 
    <xsl:template match="RECORD1"> 
    <shipment> 
     <xsl:copy-of select="."/> 
     <xsl:copy-of select="key('items', .)"/> 
    </shipment> 
    </xsl:template> 
</xsl:stylesheet> 

我和xsltproc的測試，並撒克遜人。密鑰不需要generate-id。您使用的代碼的一個主要問題是密鑰在具有相同密鑰的元素組中包含RECORD1。由於它們是通過查看前面的RECORD1元素進行分組的，因此任何給定的RECORD1元素都會最終與之前的組分組。解決方案是排除它。
