04/11/2005 Introduction the XSL What is XSL? XSL(XML Style Language) is a style sheet language applied in archives XML. It possesss a set of basic instructions destined to the visualization. So that it serves XSL? It defines styles to applying to each element of document XML and also it can be carried through small typical instructions of the programming languages. As specific searches, conditional structures, to create new tags, variable and etc.

04/11/2005 Introduction the XSL The components of the XSL language  The full XSL language logically consists of three component languages which are described in three W3C (World Wide Web Consortium) Recommendations: XPath: XML Path Language--a language for referencing specific parts of an XML document XSLT: XSL Transformations--a language for describing how to transform one XML document (represented as a tree) into another XSL: Extensible Stylesheet Language--XSLT plus a description of a set of Formatting Objects and Formatting Properties

04/11/2005 Introduction the XSL Which the importance of XSL for formatting of archives XML?  One of its main advantages is if we will have a document XML that to want that it is visualized in multiple distinct devices will be essential to use XSL.  In this project we would have one alone document XML and a document XSL for each device that to want to include. Comparison of the XSL with other style sheets  We have two possible languages with which to format the texts of a document XML to be able to be seen by screen. The first possibility is the CSS and second it is the XSL.  XSL is much more powerful that CSS and of fact is adjusted does not use it.

04/11/2005 The XSL standard The XML standard specifies how to identify data, not how to display it The XSL standard has two parts:  XSLT (the transformation standard)  XSL-FO (the part that covers formatting objects )

04/11/2005 The XSL standard XSLT (+XPATH) - Extensible Stylesheet Language for Transformations  The XSLT transformation standard is essentially a translation mechanism that lets you specify what to convert an XML tag into so that it can be displayed -- for example, in HTML.  Different XSL formats can then be used to display the same data in different ways  The XPATH is an addressing mechanism that you use when constructing transformation instructions, in order to specify the parts of the XML structure you want to transform.

04/11/2005 The XSL standard XSL-FO (language of object formatting)  XSL-FO gives you the ability to define multiple areas on a page and then link them together.  When a text stream is directed at the collection, it fills the first area and then "flows" into the second when the first area is filled. Such objects are used by newsletters, catalogs, and periodical publications.
