I didn't really understand your problem description, but this generates the required output:

['aaa'],['bbb', 'ccc', 'dddd', 'eeee', 'gggg'],['fffff']


<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">



<xsl:template match="test"> <xsl:for-each-group select="a/b[c]" group-by="@name"> <xsl:if test="position()>1">,</xsl:if> <xsl:text>['</xsl:text> <xsl:value-of select="current-group()/c" separator="', '"/> <xsl:text>']</xsl:text> </xsl:for-each-group> </xsl:template>

</xsl:stylesheet>


Note


<xsl:text disable-output-escaping="no">

you never need to use d-o-e ="no" as that is the default 9and you hardly ever need d-o-e at all)

//c[1][ancestor::b/@name=$node]"

That generates every c in the document that is the first child of any element that has an ancestor b with the required name. did you intend to select the first c in the document that is a descendant of such a b?
that would be
(//b[@name=$node]//c)[1]
but note (unless your xslt processor is being kind and rewriting it for you) // can be very expensive and you are better to use a key or for-each-group.




<xsl:value-of select="./text()"/>


you never need to start a path with ./ this is teh same as text() but using text() makes the code fragile in the face of coments or other markup in the source, better just to use


<xsl:value-of select="."/>
