4.9 Summary

This chapter discussed the XPath data model with its seven node types. It also explained location paths, expressions and patterns, predicates, abbreviated and unabbreviated location paths, and axes. You learned how to do simple arithmetic and name and node tests, as well. For additional light on this subject, see Chapter 9 of O'Reilly's XML in a Nutshell by Elliotte Rusty Harold and W. Scott Means, and Chapter 3 from O'Reilly's XSLT by Doug Tidwell.

The next chapter continues the theme by exploring XPath and XSLT functions used in expressions.
