Outputing Null values.

Hi,

Using the following code as an example, how do I output a NULL value in the 'value-of select'? Is there a NULL statement I need, or is it simply "" or " "?

Code:

<xsl:if test="string-length(.//Min)=0">
    <xsl:element name="NumericResult">
        <xsl:attribute name="UnitOfMeasure"><xsl:value-of select="$strUOM"/></xsl:attribute>
            <xsl:value-of select=""/>
    </xsl:element>                    
</xsl:if>

Thanks in advance,

Neal

There's no such thing as a null value in XSLT, you must be thinking of a different language. Do you mean a zero-length string? That's simply select="''".
