For more information and examples on writing conditional expressions, see the <xsl:if> section in the Reference

panel (Help > Reference).

Apply multiple conditional XSLT regions

You can write a simple conditional expression to insert into your XSLT page. If content is selected when you open

the Conditional Region dialog box, the content is wrapped in an

<xsl:choose> block. If you do not select content,

the

<xsl:choose> block is added at the insertion point on the page. It’s a good idea to use the dialog box to get

started and then customize the expression in Code view.

The

<xsl:choose> element is similar to the case statement in other languages. The element provides a way for you

to test a condition and take a course of action based on the result. The

<xsl:choose> element allows you to test for

multiple conditions.

1 Select Insert > XSLT Objects > Multiple Conditional Region or click the Multiple Conditional Region icon in the

XLST category of the Insert bar.

2 In the Multiple Conditional Region dialog box, enter the first condition.

In the following example, you want to test to see if the context node’s

price subelement is less than 5.

3 Click OK.

In the example, the following code is inserted in your XSLT page:

<xsl:choose>

<xsl:when test="price<5">

Content goes here

</xsl:when>

<xsl:otherwise>

Content goes here

</xsl:otherwise>

</xsl:choose>

4 To insert another condition, place the insertion point in Code view between <xsl:when> tag pairs or just before

the

<xsl:otherwise> tag, and then insert a conditional region (Insert > XSLT Objects > Conditional Region).

After you specify the condition and click OK, another

<xsl:when> tag is inserted in the <xsl:choose> block.

For more information and examples on writing conditional expressions, see the

<xsl:choose> sections in the

Reference panel (Help > Reference).

Set conditional region (If) properties

The purpose of the Set Conditional Region Property inspector is to change the condition used in a conditional region

in your XSL page. The conditional region tests the condition and takes a course of action based on the result.

❖ In the Test box, enter a new condition, and then press Enter.
