Further to your other replies, rather than use the ancestor axis this
kind of thing is generally done more naturally in XSLT with recursion.

This stylesheet (I know it doesn't look more elegant at first sight,
but recursion is much nicer, honestly) produces the output you desire:

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

  <xsl:output method="text"/>

  <xsl:template match="/">
    <xsl:apply-templates select="n"/>
  </xsl:template>

  <xsl:template match="n">

    <xsl:param name="prefix"/>

    <!-- update the prefix -->
    <xsl:variable name="current">
      <xsl:choose>
        <xsl:when test="$prefix">
          <xsl:value-of select="concat($prefix,'->',@categorie)"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="@categorie"/>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:variable>

    <!-- output the new prefix -->
    <xsl:value-of disable-output-escaping="yes" select="$current"/>
    <xsl:text>&#x0a;</xsl:text>  <!-- a newline -->

    <!-- recursively treat my child-nodes -->
    <xsl:apply-templates select="n">
      <xsl:with-param name="prefix">
        <xsl:value-of select="$current"/>
      </xsl:with-param>
    </xsl:apply-templates>

  </xsl:template>

</xsl:stylesheet>
