Re: [docbook-apps] height of rows in tables

["Bob Stayton" <bobs@sagehill.net>]

Hi Ron,
You got the part that gets the PI value into a variable, now you need the 
part that uses the variable to add the property (attribute) to the 
fo:table-row.  See the xsl:if for $bgcolor to see how that is done. 
Something like:

 <fo:table-row>
    <xsl:if test="$row.height != ''">
      <xsl:attribute name="height">
        <xsl:value-of select="$row.height"/>
      </xsl:attribute>
    </xsl:if>
