Problem with repeat sub-node to transform a XML to a CSV with XSL

I'm working on a transformation of a XML file to a CSV file.

See a piece of the XML :

<bota_form_v_20200610 xmlns:ev="http://www.w3.org/2001/xml-events" xmlns:orx="http://openrosa.org/xforms" xmlns:odk="http://www.opendatakit.org/xforms" xmlns:h="http://www.w3.org/1999/xhtml" xmlns:jr="http://openrosa.org/javarosa" xmlns:xsd="http://www.w3.org/2001/XMLSchema" id="fm_bota_2020" version="2020061000">

<md_abondance>2</md_abondance>
<md_stade_pheno>v</md_stade_pheno>
</esp_plt_rpt>

but with many 'quadrat_repeat' node which has each one many 'sous_quadrat_repeat' node and each of this node has some 'esp_plt_rpt' node.

I need one line for each 'esp_plt_rpt' sub node. And each of this line need to have all the attribute of their father (attribute of 'sous_quadrat_repeat', of 'quadra_repeat' and of parcelle"). like this :

Attr_Parc1    Attr_Parc2    Quadra_repeat1 ...   quadra_repeatN ... sous_quadrat_repeatN

And here my XSL (1.0) :

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" encoding="UTF-8" omit-xml-declaration="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:variable name="sep" select="';'" />
  <xsl:variable name="nl" select="'&#xa;'" />

  <xsl:template match="bota_form_v_20200610">
<!--    <xsl:apply-templates select="quadrat_repeat/sous_quadrat_repeat"/> 
-->
<xsl:apply-templates select="quadrat_repeat"/> 
 </xsl:template>

  <xsl:template match="esp_plt_rpt">
    <xsl:value-of select="md_abondance" />
    <xsl:value-of select="$nl" />
  </xsl:template>




  <xsl:template match="sous_quadrat_repeat">
    <xsl:variable name="tmp">
      <xsl:value-of select="ancestor::bota_form_v_20200610/@id" />
      <xsl:value-of select="$sep" />
      <xsl:value-of select="ancestor::bota_form_v_20200610/quadrat_repeat/nom_gps" />
      <xsl:value-of select="$sep" />
      <xsl:value-of select="ancestor::bota_form_v_20200610/quadrat_repeat/md_sampling" />
      <xsl:value-of select="$sep" />
      <xsl:value-of select="ancestor::bota_form_v_20200610/quadrat_repeat/zone" />
      <xsl:value-of select="$sep" />

      <xsl:value-of select="ancestor::bota_form_v_20200610/quadrat_repeat/md_densite"/>
      <xsl:value-of select="$sep" />
    </xsl:variable>


    <xsl:for-each select="ancestor::bota_form_v_20200610/quadrat_repeat/sous_quadrat_repeat/esp_plt_rpt">
      <xsl:copy-of select="$tmp"/>

      <xsl:value-of select="ancestor::bota_form_v_20200610/quadrat_repeat/sous_quadrat_repeat/md_subquadrat"/>
      <xsl:value-of select="$sep" />
      <xsl:value-of select="md_plante_latin_rpt" />
      <xsl:value-of select="$sep" />
      <xsl:value-of select="md_stade_pheno" />
      <xsl:value-of select="$sep" />

      <xsl:apply-templates select="." />
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

This code don't take a new 'sous_quadrat_repeat' when he go to a new esp_pt_rpt. So all my line have the attribute of the first sous_quadrat_repeat node.
