Subject: [xsl] sorting and grouping
I've got a sorting problem. My XML is as follows:
<person>
<name>Kermit</name>
<birthday>3</birthday>
<birthmonth>January</birthmonth>
</person>
etc.
XSLT:
<xsl:for-each select="person[birthmonth='January']">
<xsl:sort select="birthday" data-type="number"/>
<xsl:sort select="name"/>
<xsl:value-of select="birthday"/>
<xsl:text> - </xsl:text>
<xsl:value-of select="name"/>
<br/>
</xsl:for-each>
With the above code, each birthday number is repeated. What I
would like is
to have the birthday number appear only once followed by the
names of people
whose birthday that is. I suspect it can be done by testing
if the birthday
value is the same as the preceding sibling, but I can't get
it right. Does
anyone have any idea how to solve this?
