Transforming XML into Content by Using XSLT 388
More XPath and XSLT Resources 408
As you saw in the previous chapter, XML is a way to structure data hierarchically using elements and attributes, much like a relational database structures data using tables and columns. Ultimately, XML is just a different way of structuring and storing data.
This also means that you will eventually want to start pulling data out of the XML structure and formatting it for use within your application. This could mean searching an XML document to find a node or set of nodes (using XPath), or it could mean transforming the XML into another format using a style sheet (using XSLT). Both of these technologies are discussed within this chapter.
