11.6 Summary

You learned how to declare and invoke keys in this chapter using the key element and key( ) function in tandem. You also learned how to use multiple keys, how to use parameters with those keys, and how to use multiple keys with multiple documents for a cross-reference effect. Finally, you saw how to group with keys using the Muenchian method. Although you have been introduced to the usage of keys, these simple examples do not fully demonstrate the value of keys the benefits of performance gains that keys offer when processing large documents with many nodes.

In the following chapter, you'll learn how to process XML documents conditionally with XSLT using the if and choose elements.
