Re: Formatting of numbers, dynamically

Here we need again recursive template: counting down the @minor_unit, for
every processing of the template 'minor_unit' one '0'.

the XML

<root>
    <number minor_unit="3">1.123</number>
    <number minor_unit="2">1.000</number>
    <number minor_unit="4">0.120</number>
    <number minor_unit="3">12</number>
</root>

the XSL:
<xsl:template match="number">
    <xsl:variable name="format-string">
        <xsl:text>#,##0.</xsl:text>
        <xsl:call-template name="minor_unit">
            <xsl:with-param name="minor_unit" select="@minor_unit"/>
        </xsl:call-template>
    </xsl:variable>
    <xsl:value-of select="$format-string"/><br/>
    <xsl:value-of select="format-number(., $format-string)"/><br/>
</xsl:template>

<xsl:template name="minor_unit">
    <xsl:param name="minor_unit" select="2"/>
    <xsl:text>0</xsl:text>
    <xsl:if test="$minor_unit > 1">
        <xsl:call-template name="minor_unit">
            <xsl:with-param name="minor_unit" select="$minor_unit - 1"/>
        </xsl:call-template>
    </xsl:if>
</xsl:template>

the output:
#,##0.000
1.123
#,##0.00
1.00
#,##0.0000
0.1200
#,##0.000
12.000
