Элемент преобразования XML появляется в неправильном месте в документе

Question

У меня проблемы с преобразованием XML, и мне нужна помощь.

Таблица стилей должна выполнять итерацию по всем элементам суффикса и размещать содержимое без тега суффикса рядом с последним текстовым узлом в своем первом элементе блока цитаты предка (см. Требуемый вывод). Это работает, когда присутствует только один суффикс, но не когда присутствует 2, когда присутствует 2, он помещает оба суффикса рядом друг с другом в последнем текстовом узле первого блока цитаты.

Есть идеи? Я пытался ограничить выборки ancestor :: quote-block [1] в разных местах, но это не дает желаемого эффекта.

Вот простое преобразование, которое решает только проблему . Как заметили другие, проблема указана очень грязно и не допускает однозначного и однозначного толкования.

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

 <xsl:strip-space elements="*"/>

 <xsl:key name="kLastNonSufText"
   match="*[not(self::suffix)]/text()"
   use="generate-id(ancestor::quote-block[1])"/>

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

 <xsl:template match="text()[ancestor::quote-block]">
  <xsl:copy-of select="."/>

  <xsl:variable name="vQBImmed" select="ancestor::quote-block[1]"/>

  <xsl:variable name="vLastText" select=
   "key('kLastNonSufText', generate-id($vQBImmed))
      [last()]"/>

  <xsl:if test="count(.|$vLastText) = 1">
      <xsl:copy-of select="($vQBImmed//suffix)[last()]/text()"/>
  </xsl:if>
 </xsl:template>

 <xsl:template match="suffix"/>
</xsl:stylesheet>

          2000, EME and EWS reached an agreement to negotiate
          towards a direct contract for coal haulage by rail (on a
          DIY basis), which would replace the previous indirect E2E
          arrangements that EME had in place with ECSL. An internal
          EWS e-mail noted:

            yesterday morning for LBT-Fiddlers @ £[…]/tonne as
            agreed. This rate until 16th September pending a

            so far as Edison are concerned. The Enron flows we have
            left are to British Energy’s station at Eggborough;
            from Immingham, Redcar and Hull</emphasis>. Also to
            Enron’s own power station at Wilton – 250,000
            tonnes/year. I think we are stuck Enron [sic] on the
            Eggborough traffic until next April when British Energy
            will, hopefully take over their own coal procurement.
