Table 4-3: XML style sheet for a one-to-one relationship – country_dest.xsl

The XML style sheet in Table 4-3 introduces the if statement as well as the ability to sort elements.
The if statement executes code based on the evaluation of the condition given in the "test" attribute,e.g.

<xsl:if test="population >= 10000">

Big Town

</xsl:if>
<xsl:if test="population < 10000">

Small Town

</xsl:if>

Possible expressions for the condition are

Operator	Meaning
=	equality of two values
!=	inequality of two values
<	less than
>	greater than
<=	less than or equal
>=	greater than or equal
and	logical and-conjunction
or	logical or-conjunction

Output can be sorted based on the value of the select attribute of the <xsl:sort> element.
