counting equal entries

[R. Heydenreich]

Hi all,
I try to create an index page from a document. The idea behind is to
collect a certain word and list it with *all* occurences in the
document, like

foo .... 12, 23, 45
bar .... 2, 5, 88

and so on. I have a XML document which contains entries with different
classes (Java classes).
I have a XSL stylesheet which collects all entries in a sorted order.
But there is one separate entry for each occurence:

foo ... 12
foo ... 23
foo ... 45
bar ... 2

and so on.

Code follows:

<xsl:for-each select="key('index-key', $lower-alphabet)">
<xsl:sort select="@name" case-order="lower-first"/>
<xsl:call-template name="display-index-item">
<xsl:with-param name="item" select="." />
</xsl:call-template>
</xsl:for-each>

The $lower-alphabet is only a variable containing all lower letters.
How can I pass an indicator to the template "display-index-item" where
I can decide if an entry has the same name as the previous one?

TIA,
Ralf.

Hi,

I'm not sure if this will solve the problem, but you might look at this:

Given this xml:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<occ name="foo" line="23"/>
<occ name="foo" line="12"/>
<occ name="bar" line="5"/>
<occ name="bar" line="88"/>
<occ name="foo" line="45"/>
<occ name="bar" line="2"/>
</root>

#########################
,this stylsheet:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="text"/>
<xsl:key name="index-key" match="occ" use="@name"/>

<xsl:template match="/">
<xsl:for-each select="//occ[generate-id(.)=generate-id(key('index-key',@name))]/@name">
<xsl:sort select="." case-order="lower-first"/>
<xsl:value-of select="."/>:
<xsl:apply-templates select="//occ[@name=current()]">
<xsl:sort select="@line" case-order="lower-first"/>
</xsl:apply-templates>
</xsl:for-each>
</xsl:template>

<xsl:template match="occ">
</xsl:template>

</xsl:stylesheet>

,will output:

bar: 2, 5, 88, foo: 12, 23, 45,
