Though XQuery is capable of handling mundane tasks like those described in the previous section, it is designed to access XML data. Right now, we will look at some simple queries that require an XML document as their input. For this purpose, we will use videos.xml, which is installed with Stylus Studio in the \examples\VideoCenter directory. You can also find a copy of this XML document on the Stylus Studio Web site.
XQuery allows you to access the file directly from either of these locations, using a suitable URL as an argument for its doc() function. If you wanted to retrieve and display the entire file from your Stylus Studio installation directory, your doc() might look like this:
To fetch this document from the Stylus Studio Web site, you would need a doc() like this:
(The latter doc() function will work only if you are online; and if you are behind a corporate firewall you might have to modify your Java configuration to make it work.)
URLs like those used in the previous example can be a bit unwieldy, but there are some shortcuts you can use.
." (dot).c:\xquery\videos.xml, for example) and work with it from that location. Once you have done this, you can use the command line option -s c:\xquery\videos.xml and again be able to refer to the input document in your XQuery code as "." (dot).
The videos.xml document contains a number of sections: video_template, actors, and videos. You might want to open this document in the XML Editor to get acquainted with it if you are not already familiar with it.
