Additional Editing Procedures

Previous Top Next

Additional to the content editing and presentation procedures, StyleVision provides a number of useful features that can be used in the SPS. These procedures are listed below and described in detail in the sub-sections of this section.

•	Authentic Node Properties. Individual nodes in the XML document have Authentic View-specific properties. Nodes can be defined to be non-editable, to be displayed with markup tags, to display user information on mouseover, etc.

•	Additional Validation. A node can be tested using an XPath expression to return a Boolean value that determines whether user input for that node is valid. This test is in addition to document validation against a schema.

•	Input Formatting (Formatting Numeric Datatypes). The formatting of numeric datatype content, including dates, can be customized using the tools provided by the Input Formatting feature.

•	Working with Dates. In Authentic View, a graphical date-picker ensures that dates are entered in the correct XML Schema format. Furthermore, dates can be manipulated and formatted as required.

•	Parameters. Parameters are declared at the global SPS level with a default value. These values can then be overridden at runtime by values passed to the stylesheet from the command line.

•	Unparsed Entity URIs. URIs can be stored in unparsed entities in the DTD on which an XML document is based. The Unparsed Entity URI feature enables images and hyperlinks to use these URIs as target URIs.

•	Using Scripts. StyleVision contains a JavaScript Editor in which JavaScript functions can be defined. These functions are then available for use as event handlers anywhere within the SPS, and will take effect in the output HTML document.
