To the top
2. In the XSL Transformation dialog box, click the Plus (+) button next to XSLT Parameters.
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.
2. In the Conditional Region dialog box, enter the conditional expression to use for the region.
In the following example, you want to test to see if the context node’s @available attribute value is true.
