How best is the following text extracted from the following xml, possibly using keys or some other xslt constructs? ... The basic approach involves: Gee, that sounds like a good approach to me: - using keys to get a unique list of possible values for the @category attribute <xsl:key name="cats" match="*[@category]" use="@category"/> - iterating over these values
- printing each followed by a colon <xsl:value-of select="@category"/>: <xsl:text/> - getting a unique list of all xml element names which contain this particular attribute value
printing each <xsl:value-of select="name(.)"/> printing an endline
