Hi Peter,
Hunsberger, Peter wrote:
I'm still shaky on grouping with keys so I've probably missed something
obvious, but I can't get a grouping to work when it has to group on a
recursive structure. The input looks essentially like the following:
<list>
<a type="1" flag="false"/>
<b type="2" flag="false"/>
<c type="3" flag="false">
<d type="4" flag="true"/>
<e type="4" flag="true"/>
<f type="5" flag="true"/>
<g type="5" flag="true"/>
</c>
</list>
<list>
<a type="1" flag="false"/>
<b type="2" flag="false"/>
<c type="3" flag="false">
<d type="7" flag="false">
<e type="4" flag="true"/>
<e type="4" flag="true"/>
</d>
</c>
</list>
Where, if there are adjacent nodes with the same type than the flag will be
true, otherwise the flag will always be false. It could be possible for
adjacent nodes to have the same type with the flag set to false. The same
structure could go many more levels deep than shown here. The desired output
is
Off the top of head, so test it out...
<xsl:template match="list">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="a | b | c | d | e | f">
<xsl:element name="name()">
<xsl:attribute name="type">
<xsl:value-of select="@type"/>
</xsl:attribute>
<xsl:attribute name="flag">
<xsl:value-of select="@flag"/>
</xsl:attribute>
<xsl:if test="boolean(./*)">
<group>
<xsl:apply-templates/>
</group>
</xsl:if>
</xsl:element>
</xsl:template>
