out of this xml:
<xml>
<el>
<node>A</node>
<rel>
<el>
<node>X</node>
<obj>myobject</obj>
</el>
</rel>
</el>
<el>
<node>A</node>
<rel>
<el>
<node>X</node>
<obj>myobject</obj>
</el>
</rel>
</el>
<el>
<node>A</node>
<rel>
<el>
<node>Y</node>
<obj>myobject</obj>
</el>
</rel>
</el>
...
<el>
<node>B</node>
<rel>
<el>
<node>X</node>
<obj>myobject</obj>
</el>
</rel>
</el>
...
</xml>
i want to get a list of the first level nodes (A, B, C..) with their related
nodes (X, Y, Z...) but removing duplicates, so i'd like to get:
A-XY
B-X
...
but using this -or simmilar principle- basic duplicate removing xsl script:
<!-- to avoid node group repetition -->
<xsl:template match = "/">
<xsl:apply-templates
select="/xml/el[obj='myobject'][not(node=following::node)]">
<xsl:sort select="node" />
</xsl:apply-templates>
</xsl:template>
<xsl:template match="el">
...
<xsl:value-of select="node">-
<xsl:call-template name="XXX"><xsl:with-param name="node" ><xsl:value-of
select="node" /></xsl:with-param></xsl:call-template>
...
</xsl:template>
<xsl:template name="XXX">
<xsl:for-each
select="/xml/el[node=$node]/rel/el[obj='myobject'][not(node=following-siblin
g::*)]">
<xsl:value-of select="node">
</xsl:for-each>
</xsl:template>
i wrongly get this:
A-XXY
B-X
...
as i don't have tight performance problems i don't need to resort to
muenchian methods, any idea on how to solve this ?
thanks
