browser can display the transformed data. Deploying pages for server-side transformations, however, is somewhat complex, and requires that you

have access to an application server.

When working with server-side XSL transformations, you can use Dreamweaver to create XSLT pages that generate full HTML documents (entire

XSLT pages), or XSLT fragments that generate a portion of an HTML document. An entire XSLT page is similar to a regular HTML page. It

contains a <body> tag and a <head> tag, and lets you display a combination of HTML and XML data on the page. An XSLT fragment is a piece of

code, used by a separate document, that displays formatted XML data. Unlike an entire XSLT page, it is an independent file that contains no

<body> or <head> tag. If you want to display XML data on a page of its own, you would create an entire XSLT page, and bind your XML data to it.

If, on the other hand, you wanted to display XML data in a particular section of an existing dynamic page—for example, a dynamic home page for

a sporting goods store, with sports scores from an RSS feed displayed on one side of the page—you would create an XSLT fragment and insert a

reference to it in the dynamic page. Creating XSLT fragments, and using them in conjunction with other dynamic pages to display XML data, is the

more common scenario.

The first step in creating these types of pages is to create the XSLT fragment. It is a separate file that contains the layout, formatting, and so on of

the XML data that you eventually want to display in the dynamic page. Once you create the XSLT fragment, you insert a reference to it in your

dynamic page (for example, a PHP or ColdFusion page). The inserted reference to the fragment works much like an Server Side Include (SSI) —

the formatted XML data (the fragment) resides in a separate file, while in Design view, a placeholder for the fragment appears on the dynamic

page itself. When a browser requests the dynamic page containing the reference to the fragment, the server processes the included instruction

and creates a new document in which the formatted contents of the fragment appear instead of the placeholder.

1. Browser requests dynamic page 2. Web server

finds page and passes it to application server 3. Application server scans page for instructions and gets XSLT fragment 4. Application server

performs transformation (reads XSLT fragment, gets and formats xml data) 5. Application server inserts transformed fragment into page and

passes it back to the web server 6. Web server sends finished page to browser

You use the XSL Transformation server behavior to insert the reference to an XSLT fragment in a dynamic page. When you insert the reference,

Dreamweaver generates an includes/MM_XSLTransform/ folder in the site’s root folder that contains a runtime library file. The application server

uses the functions defined in this file when transforming the specified XML data. The file is responsible for fetching the XML data and XSLT

fragments, performing the XSL transformation, and outputting the results on the web page.

The file containing the XSLT fragment, the XML file containing your data, and the generated run-time library file must all be on the server for your

page to display correctly. (If you select a remote XML file as your data source—one from an RSS feed, for example—that file must of course

reside somewhere else on the Internet.)

You can also use Dreamweaver to create entire XSLT pages for use with server-side transformations. An entire XSLT page works in exactly the

same way as an XSLT fragment, only when you insert the reference to the entire XSLT page using the XSL Transformation server behavior, you

are inserting the full contents of an HTML page. Thus, the dynamic page (the .cfm, .php, or .asp page that acts as the container page) must be

cleared of all HTML before you insert the reference.

Dreamweaver supports XSL transformations for ColdFusion, ASP, and PHP pages.

Note: Your server must be correctly configured to perform server-side transformations. For more information, contact your server administrator.

Client-side XSL transformations

You can perform XSL transformations on the client without the use of an application server. You can use Dreamweaver to create an entire XSLT

page that will do this; however, client-side transformations require manipulation of the XML file that contains the data you want to display.

Additionally, client-side transformations will only work in modern browsers (Internet Explorer 6, Netscape 8, Mozilla 1.8, and Firefox 1.0.2). For

more information on browsers that do and don’t support XSL transformations, see www.w3schools.com/xsl/xsl_browsers.asp.

First, create an entire XSLT page and attach an XML data source. (Dreamweaver prompts you to attach the data source when you create the new

page.) You can create an XSLT page from scratch, or you can convert an existing HTML page to an XSLT page. When you convert an existing

HTML page to an XSLT page you must attach an XML data source using the Bindings panel (Window > Bindings).
