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

| < |

| > |

| <= |

| >= |
greater than or equal |
| and |
