You can find out the depth of the current node within a nested structure by
counting the number of ancestors of that node using the following XPath:

  count(ancestor::*)

In the following stylesheet, I use a variable to store that information and
to construct the lines that you want.

<xsl:template match="root">
  folderTree = gFld("<xsl:value-of select="normalize-space(text()[1])" />"
, "" )
  <xsl:apply-templates />
</xsl:template>

<xsl:template match="cat|child">
  <xsl:variable name="depth" select="count(ancestor::*)" />
  aux<xsl:value-of select="$depth" /><xsl:text> = insFld(</xsl:text>
  <xsl:choose>
    <xsl:when test="$depth = 1">folderTree</xsl:when>
    <xsl:otherwise>aux<xsl:value-of select="$depth - 1" /></xsl:otherwise>
  </xsl:choose>
  <xsl:text>, gFld("</xsl:text><xsl:value-of
select="normalize-space(text()[1])" />", ""))
  <xsl:apply-templates />
</xsl:template>

Tested and works on SAXON.

I hope that helps,
