XSLT Aggregation using sort with Muenchian Method for min and max
Tag : xml , By : Hunter
Date : November 28 2020, 09:01 AM

hop of those help? I understand the Muenchian Method indexes the entire document at first read. But how can one sort prior or within grouping but not on its key? Specifically, how can I order a sibling of the key in order to calculate min and max of a series of element values? , How about this way?

How to group in XSLT using Muenchian Method?

Tag : xml , By : Dave M
Date : March 29 2020, 07:55 AM
hop of those help? I'm quite new to XSLT and I'm using XSLT 1.0. Now I need to group some stuff in a quite big XML file. There are lots of examples out there but none worked for me for some reason. I'm able to group the info I want, but I also get some extra text in my output xml. Here's what I'm doing right now; , Add a template doing
<xsl:template match="/">
  <xsl:apply-templates select="//items"/>
</xsl:template>

XSLT Muenchian Method

Tag : xml , By : Search Classroom

I hope this helps . I'm working with an XSLT that someone else designed. Back in that time the xml structure was like this: , What you could try is replace the code
<xsl:key name="module-index" match="errata_section" use="module_impacted"/>

...

<xsl:for-each select="//errata_section[generate-id(.)=generate-id(key('module-index', module_impacted)[1])]">
 <xsl:sort select="module_impacted"/>

<!-- Do some processing -->

</xsl:for-each>

<xsl:key name="module-index" match="errata_section" use="module_impacted"/>
<xsl:key name="group" match="errata_section/module_impacted" use="."/>

...

<xsl:for-each select="//errata_section/module_impacted[generate-id() = generate-id(key('group', .)[1])]">">
 <xsl:sort select="."/>
 <xsl:variable name="current-group" select="key('module-index', .)"/>
 <xsl:variable name="current-grouping-key" select="."/>

<!-- Do some processing -->

</xsl:for-each>

<xsl:for-each select="//errata_section[generate-id(.)=generate-id(key('module-index', module_impacted)[1])]">
 <xsl:sort select="module_impacted"/>

XSLT Muenchian method complex

wish help you to fix your issue You were not far off, with your use of keys, but the main problem as far as I can see was you had some nested xsl:for-each statements, which weren't taking into account the context. For example
<xsl:for-each select="$ROOT_A/ES_PRODUCT/trailerProject/wontrailerproject/producer/ES_PERSON[generate-id() = generate-id(key('producers',@pe_fullname)[1])]">
   <xsl:variable name="thisProducer" select="@pe_fullname"/>

xsl:sort with preceding-sibling XSLT 1.0 XSL-FO muenchian xsl:key

Tag : sorting , By : msugar
Date : March 29 2020, 07:55 AM
should help you out If node-set() isn't working, then you need to do the sorting again just to get the previous item:
<xsl:key name="all" match="catalogSeqNumber" use="true()" />

<xsl:template name="SortParts">
  <xsl:apply-templates
      select="catalogSeqNumber[key('kfigNo', @figureNumber)]">
      <xsl:sort select="itemSeqNumber/partRef/@partNumberValue"/>
      <xsl:sort select="@figureNumber"/>
      <xsl:sort select="@item"/>
  </xsl:apply-templates>
</xsl:template>

<xsl:template match="catalogSeqNumber">
  <xsl:variable
      name="figNo"
      select="concat(@figureNumber,@figureNumberVariant)"/>
  <xsl:variable name="current-position" select="position()"/>
  <xsl:variable name="prfigNo">
    <xsl:for-each select="key('all', true())">
      <xsl:sort select="itemSeqNumber/partRef/@partNumberValue"/>
      <xsl:sort select="@figureNumber"/>
      <xsl:sort select="@item"/>
      <xsl:if test="position() = $current-position - 1">
        <xsl:value-of select="concat(@figureNumber,@figureNumberVariant)" />
      </xsl:if>
    </xsl:for-each>
  </xsl:variable>
  <fo:table-row>
    <fo:table-cell padding="3pt">
      <fo:block>
        <xsl:value-of
            select="itemSeqNumber/partRef/@partNumberValue"/>
      </fo:block>
    </fo:table-cell>
    <fo:table-cell padding="3pt">
      <fo:block>
        <xsl:if test="$figNo">
          <xsl:text> </xsl:text>
          <xsl:value-of select="$figNo"/>
          <xsl:text> </xsl:text>
          <xsl:value-of select="$prfigNo"/>
        </xsl:if>
      </fo:block> 
    </fo:table-cell>
    <fo:table-cell padding="3pt">
      <fo:block>
        <xsl:value-of select="concat(@item,@itemVariant)"/>
      </fo:block>
    </fo:table-cell>
    <fo:table-cell padding="3pt">

XSLT MUENCHIAN METHOD for all the nodes

Tag : xslt , By : DarrenBeck
Date : March 29 2020, 07:55 AM
it fixes the issue If you want to get the unique value attributes by product, you will have to make a reference to the product part of the key
 <xsl:key name="values" match="@value" use="concat(generate-id(ancestor::Product), '|', .)" />

<xsl:for-each select=".//@value[generate-id() = generate-id(key('values', concat($id, '|', .))[1])]">

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

  <xsl:key name="values" match="@value" use="concat(generate-id(ancestor::Product), '|', .)" />

  <xsl:template match="Product">
    <xsl:variable name="id" select="generate-id()" />
    <xsl:copy>
        <xsl:for-each select=".//@value[generate-id() = generate-id(key('values', concat($id, '|', .))[1])]">
            <values><xsl:value-of select="." /></values>
        </xsl:for-each>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

<xsl:for-each-group select=".//@value" group-by=".">

<xsl:for-each select="distinct-values(.//@value)">
