XSLT集團通過+計數基於幾個標籤水平

Question

<result> 
    <account id="123456"> 
     <missing_data missing_in="Archimede"/> 
      <line_not_found db_table="PRODUCT" id="PDT"> 
      </line_not_found> 
      <line_not_found db_table="ADRESS" id="ADR"> 
      </line_not_found> 
     </missing_data> 
     <missing_data missing_in="Cassiope"> 
      <line_not_found db_table="PRODUCT" id="PDT"> 
      </line_not_found> 
      <line_not_found db_table="PRODUCT" id="PDT"> 
      </line_not_found> 
      <line_not_found db_table="ADRESS" id="ADR"> 
      </line_not_found> 
      <line_not_found db_table="ADRESS" id="ADR"> 
      </line_not_found> 
      <line_not_found db_table="ADRESS" id="ADR"> 
      </line_not_found> 
      <line_not_found db_table="ADRESS" id="ADR"> 
      </line_not_found> 
     </missing_data> 
    </account> 
</result> 

我想組和計數missing_data @ missing_in和line_not_found @ ID

例如，在這種情況下： 阿基米德 - PDT：1 阿基米德 - ADR：1 Cassiope - PDT：2 Cassiope - ADR：4

我不得不承認我是XSLT的完整初學者。 我試圖從Xslt distinct select/Group by得到啓發，但問題並不完全相同，因爲我的密鑰是複合的，但是來自多個XML標籤。

我的XSL：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> 
    <xsl:key name="missing_data_key" match="line_not_found" use="concat(../@missing_in, ',', @id)"/> 
    <xsl:template match="/"> 
    <xsl:for-each select="result/account"> 
     <xsl:value-of select="@id" /> 
     <xsl:for-each select="missing_data/line_not_found[ 
    count(
     .|key('missing_data_key', @id)[1] 
     ) = 1 
    ] 
"> 
      <ul> 
       <xsl:value-of select="@id"/> 
    (absent dans 
    <xsl:value-of select="../@missing_in"/> 
    ) 
    <xsl:value-of select="' - '"/> 
       <xsl:value-of select=" 
     count(
      key('missing_data_key', ../@missing_in)[ 
       count(
        key('missing_data_key', concat(../@missing_in,',',@id))[1] 
       ) = 1 
      ] 
     ) 
     "/> 
      </ul> 
     </xsl:for-each> 
    </xsl:for-each> 
    </xsl:template> 
</xsl:stylesheet> 

XSLT 1強制在這個項目上

在此先感謝

Answer 1

因爲你是分組在XSLT 1.0，你必須使用Muenchian分組的元素實現你是什麼試圖做的事：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> 

    <xsl:output method="text" /> 

    <!-- Use the following key to index all line_not_found elements 
     in the document by their id --> 
    <xsl:key name="line-key" 
      match="missing_data/line_not_found" 
      use="@id" /> 

    <xsl:template match="missing_data"> 
     <!-- Obtain information from current node before losing the 
      context --> 
     <xsl:variable name="id" select="generate-id()" /> 
     <xsl:variable name="location" select="@missing_in" /> 
     <!-- Obtain the first element of each group which parent is the current missing_data element --> 
     <xsl:for-each select="line_not_found[generate-id() = generate-id(key('line-key', @id)[generate-id(..) = $id][1])]"> 
      <!-- Counts the subset of line_not_found elements which are children of 
       the current missing_data parent (put into in a variable for clarity) --> 
      <xsl:variable name="count-children" select="count(key('line-key', @id)[generate-id(..) = $id])" /> 
      <xsl:value-of select="concat($location, ' - ', @id, ' : ', $count-children, ' ')" /> 
     </xsl:for-each> 
    </xsl:template> 


</xsl:stylesheet>
