Hi all,
I'm using AurigaDoclet for creating a PDF version of JavaDoc from my java
sources. This doclet uses XSL-FO for doing this. There is a XSL stylesheet
for converting the resulting XML to FO. This XSL contains some information
about creating an index page, but unfortunately every entry is placed on a
single row (even equal entries). Now I've tried to correct the stylesheet,
but it doesn't work. I have introduced a global variable (oldentry) which
stores the old entry for each item. If the template is called repeatedly,
it tests for the value of oldentry and if it is equal to the actual entry,
then a simple comma followed by the new page number should be printed. If
not, a new row should be printed. But none of this happens. Can anyone
tell me what's wrong?
I used this code:
<!--

<xsl:template name="generate-index">
<xsl:param name="alphas" select="$upper-alphas" />

<xsl:call-template name="display-index-items">
<xsl:with-param name="alphabet" select="substring($alphas, 1, 1)" />
</xsl:call-template>
<xsl:call-template name="generate-index">
<xsl:with-param name="alphas" select="substring($alphas, 2)" />
</xsl:call-template>

</xsl:template>
