XSLT-sters,
Is the grouping-size attribute of xsl:number an attribute
value template? The spec says:
The xsl:number element is used to insert a formatted number
into the result tree. The number to be inserted may be specified
by an expression. The value attribute contains an expression.
The expression is evaluated and the resulting object is converted
to a number as if by a call to the number function. The number
is rounded to an integer and then converted to a string using
the attributes specified in [7.7.1 Number to String Conversion
Attributes]; in this context, the value of each of these
attributes is interpreted as an attribute value template.
But this XSLT:
<!-- Show the oldest five deceased authors -->
<xsl:for-each select="$authors/author[life-span/born and life-span/died]">
<xsl:sort select="life-span/died - life-span/born" order="descending"/>
<xsl:variable name="gsize" select="1"/>
<xsl:if test="position() <= 5">
<xsl:element name="oldest">
<xsl:attribute name="gsize">
<xsl:value-of select="$gsize"/>
</xsl:attribute>
<xsl:attribute name="age">
<xsl:number value="life-span/died - life-span/born"
grouping-size="1" grouping-separator="."/>
</xsl:attribute>
<xsl:attribute name="age2">
<xsl:number value="life-span/died - life-span/born"
grouping-size="{$gsize}" grouping-separator="."/>
</xsl:attribute>
<xsl:attribute name="born">
<xsl:value-of select="life-span/born"/>
</xsl:attribute>
<xsl:attribute name="died">
<xsl:value-of select="life-span/died"/>
</xsl:attribute>
<xsl:attribute name="name">
<xsl:value-of select="concat(name/first, " ",
name/last)"/>
</xsl:attribute>
</xsl:element>
</xsl:if>
</xsl:for-each>
produces this output:
<oldest gsize="1" age="8.9" age2="89" born="1886" died="1975" name="Rex
Stout"/>
<oldest gsize="1" age="8.8" age2="88" born="1906" died="1994" name="Michael
Innes"/>
<oldest gsize="1" age="8.7" age2="87" born="1895" died="1982" name="Ngaio
Marsh"/>
<oldest gsize="1" age="8.6" age2="86" born="1907" died="1993" name="Leslie
Charteris"/>
<oldest gsize="1" age="8.6" age2="86" born="1890" died="1976" name="Agatha
Christie"/>
for a list of authors that looks like:
<author>
<name>
<first>Agatha</first>
<last>Christie</last>
</name>
<life-span>
<born>1890</born>
<died>1976</died>
</life-span>
</author>
The "age" attribute comes out as expected, but "age2" uses "{$gsize}"
which seems to have no affect at all.
Am I missing something or does this attribute need AVT processing?
Thanks,
Phil
