XSL font-size calculation

Question

I'm new in xsl, and have a question about the calculation of font-size.

I always use a certain number in font-size like font-size="16pt".

Is there any possibility that I can calculate the font-size?

I tried font-size="100 div 5" or using a parameter like font-size="$fontsize" but neither works fine.

Answer 1

I tried font-size="100 div 5" or using a parameter like font-size="$fontsize" but neither works fine.

Try:

font-size="{100 div 5}" 

or:

font-size="{$fontsize}" 

For explanation, see: Attribute Value Templates

Note that you can always use the more verbose method:

<xsl:attribute name="font">
    <xsl:value-of select="100 div 5"/>
</xsl:attribute>
