Using Parameters to Store Values that Change
The use of XSLT parameters is similar to that of XSLT variables. The main difference is that the value of a parameter can change during the run of the style sheet, or be passed in from an outside environment. The value of a variable, once set, cannot be changed. The following table describes two kinds of parameters you can use in style sheets.
| Parameter type | Description |
|---|---|
| Local parameters | Used for passing data from one template rule to another. For example, you can pass a parameter to a named template, based on some condition in a given template rule. This enables you to control the way the named template behaves. |
| Global parameters | Used for passing values into a style sheet. This enables the style sheet to perform particular steps, depending on a value supplied by the user. In Internet Explorer, parameters are passed to a style sheet using script. |
This section contains the following topics.
