Hi,
hello i have one xml file (bellow one stract) and i want to
group noder and
order using xslt.
i have into one xml a lot of nodes like this:
<registro>
<producto_id>1</producto_id>
<top_orden>1</top_orden>
<categoria_id>1</categoria_id>
<categoriadetalle_nombre>uno</categoriadetalle_nombre>
</registro>
<registro>
<producto_id>3</producto_id>
<top_orden>2</top_orden>
<categoria_id>4</categoria_id>
<categoriadetalle_nombre>uno</categoriadetalle_nombre>
</registro>
<registro>
<producto_id>21</producto_id>
<top_orden>2</top_orden>
<categoria_id>2</categoria_id>
<categoriadetalle_nombre>dos</categoriadetalle_nombre>
</registro>
..................
i want to group using categoriadetalle_nombre and order by top_orden
<xsl:key name="cat" match="registro" use="categoriadetalle_nombre"/>
<xsl:template match="*[registro]">
<xsl:copy>
<xsl:apply-templates select="@*"/>
<xsl:for-each select="registro[generate-id() = generate-id(key('cat',
categoriadetalle_nombre))]">
<cat num="{categoriadetalle_nombre}">
<xsl:apply-templates select="key('cat', categoriadetalle_nombre)">
<xsl:sort select ="top_orden"/>
</xsl:apply-templates>
</cat>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
But you didn't mention what do you want to order. The groups, or the entries
inside the groups? The stylesheet above does the latter. If you want to order
the groups, did you want to order by the largest number in the group?
