3 In the Add Parameters dialog box, enter a name for the parameter in the Name box. The name can only contain
alphanumeric characters. It cannot contain spaces.
4 Do one of the following:
• If you want to use a static value, enter it in the Value box.
• If you want to use a dynamic value, click the dynamic icon next to the Value box, complete the Dynamic Data dialog
box, and click OK. For more information, click the Help button in the Dynamic Data dialog box.
5 In the Default Value box, enter the value you want the parameter to use if the page receives no run-time value, and
click OK.
Edit an XSLT parameter
1 Open the XSL Transformation dialog box. You can do this by double-clicking an XSL Transformation server
behavior in the Server Behaviors panel (Window
> Server Behaviors), or by adding a new XSL Transformation
server behavior.
2 Select a parameter from the XSLT parameters list.
3 Click the Edit button.
4 Make your changes and click OK.
Delete an XSLT parameter
1 Open the XSL Transformation dialog box. You can do this by double-clicking an XSL Transformation server
behavior in the Server Behaviors panel (Window
> Server Behaviors), or by adding a new XSL Transformation
server behavior.
2 Select a parameter from the XSLT parameters list.
3 Click the minus (-) button.
Create and edit conditional XSLT regions
You can create simple conditional regions or multiple conditional regions on an XSLT page. You can either select an
element in Design view and apply a conditional region to the selection, or you can insert a conditional region wherever
the insertion point is in the document.
For example, if you wanted to display the word “Unavailable” next to the price of an item when the item is unavailable,
you type the text “Unavailable” on the page, select it, and then apply a conditional region to the selected text.
Dreamweaver surrounds the selection with
<xsl:if> tags, and only displays the word “Unavailable” on the page when
the data match the conditions of the conditional expression.
Apply a conditional XSLT region
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 will be wrapped in an
<xsl:if> block. If you rcontent is not selected, the
<xsl:if> 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:if> element is similar to the if 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:if> element allows you to test an expression for
a single true or false value.
1 Select Insert > XSLT Objects > Conditional Region or click the Conditional Region icon in the XLST category of
the Insert panel.
