xslt test decimal length

Hi experts,

I would like to test a numeric value coming from an XML node.

I have this field in a xsl form

<input name="vpreven" type="text" id="vpreven" size="15" maxlength="{//vpreven
/@length}" style="text-align:right" >
<xsl:if test="(//vpreven!=0)">
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.000000')"/> </xsl:attribute>
</xsl:if>
</input>

I get as result 6 decimal numbers e.g. 10.234567

I would like to test the decimal length in order to put the right format
e.g
10.543 -> <xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.000')"/>
10.2 -> <xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.0')"/>
10.87655 -> <xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.00000')"/>

Thank you for you comments,

Regards

Thanks! I do it like this,

<xsl:choose>
<xsl:when test="(string-length(substring-after(string(//vpreven), '.')) = 3 )">
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.000')"/>
</xsl:attribute>
</xsl:when>
<xsl:when test="(string-length(substring-after(string(//vpreven), '.')) = 4 )">
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.0000')"/>
</xsl:attribute>
</xsl:when>
<xsl:when test="(string-length(substring-after(string(//vpreven), '.')) = 5 )">
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.00000')"/>
</xsl:attribute>
</xsl:when>
<xsl:when test="(string-length(substring-after(string(//vpreven), '.')) = 6 )">
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.000000')"/>
</xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:attribute name="value">
<xsl:value-of select="format-number(//vpreven,'#,###,###,###,###.00')"/>
</xsl:attribute>
</xsl:otherwise>
</xsl:choose>
