XSLT

Summary

In this chapter, we’ve examined a several ways to generate links and cross-references between different parts of a document. If your XML document has a reasonable amount of structure, you can use the id() and key() functions to define many different relationships between the parts of a document. Even if your XML document isn’t structured, you may be able to use key() and generate-id() to create simple references. In the next chapter, we’ll look at sorting and grouping, two more ways to organize the information in our XML documents.
