Overview of XSLT

The general XSL approach of selecting elements on the basis of specific criteria can also help address a different problem. The proliferation of different DTDs for the same logical type of document can pose severe headaches for managers developing applications that must exchange such documents. Such a scenario is highly likely in applications such as supply chain management where two companies want to exchange conceptually the same information but already have DTDs that they use internally. Also, industry groups in finance, telecommunications, and transportation are defining DTDs for transactions in those industries. In some cases, multiple industry groups are working on the same problem, creating the potential for dueling standards.

In recognition of this problem, many XML professionals would like a straightforward means of transforming documents from one data format to another. XSL already seems to have many of the building blocks. It has mechanisms for searching through XML documents to locate specific elements. It has mechanisms for outputting new documents on the basis of this processing. What if, instead of generating a formatting object document, we generated a plain old XML document?
