Chapter 8. Accessing Data with XML Tags
In this chapter, you learned how to access XML data with the XML tag library provided by JSTL. The JSTL XML tag library makes extensive use of XPath, a standard query language developed by the W3C that enables you to query XML documents. JSTL uses XPath to specify individual elements that you want to access, collections you want to iterate over, and expressions you want to use for Boolean comparisons.
Now you know how to process XML. As you learned in this chapter, XML is often obtained from files residing on the Web server. XML can also come from completely external sources. In the next chapter, we show you how to access external data sources. Often that data is XML, and can be processed using the tags we discussed in this chapter.
