Abstract
This chapter aims to give a reasonably comprehensive definition and motivation for the various aspects of the generic XML language and also to illustrate these aspects with some existing XML dialects or vocabularies. We describe elements, attributes, child elements, and the hierarchical structure of XML. We talk about “well-formedness” of an XML document and how to identify errors in a document’s structure. We discuss the use of namespaces and end with a brief discussion of validating documents with respect to DTDs and XML Schema. Readers already familiar with all aspects of XML can skip this chapter and read about the functions used to work with XML in R, which are the subject of each of Chapters 3, 4, 5, and 6.
