Föreläsning

The lecture starts 10.15 Introduction to the course and general course information during the first hour. The second hour is devoted to introducing XML in general, and how to write DTDs, which is required to complete the first lab assignment. Prepare by reading this summary of the lectureXML is a recommendation for how different types of data can be structured in tree structures, which are easy to understand and clear to both humans and computers. Examples of areas where XML is used is xhtml for coding web pages, SMIL (the language to encode MMS), DocBook (a highly structured document description languages) and JDF (a language to transmit information between different computer systems as part of a printing process). One can roughly divide the uses of document formats like HTML and SMIL, and data format JDF. There are a number of major benefits of using an XML-based format over other types of formats, such as:
Data is described by means of a hierarchy of "elements". At the top is a "top element" such as the element "html" in the XHTML document. An element may contain zero, one or more other elements. Element is encoded in the form <element-name> element content </ element-name>. So called "attributes" can be associated to elements. For example, the attribute "href" is associated with the element 'a' in the following way in html: <a href="http://www.kth.se> Link to KTH </ a> A set of elements, attributes, and the way it is permitted to combine these is called an "XML vocabulary." Such a set of rules and restrictions ("constraints") can be defined by a DTD. If an instance document (ie an XML document containing data) is associated with a DTD, it is possible to "validate" the document against the DTD, which means that you can see if/that the instance document follows the rules that are set in the DTD. It thus provides an opportunity for a program to check that the document contains no errors. Besides the ability to validate the instance document, a DTD is an easy way to concisely define how the creator of the vocabulary meant it to be used. The risk of misunderstandings are reduced. Unfortunately, it is sometimes not possible to define every constraint the vocabulary should have using a DTD. Some limitations have to be written as comments, and these restrictions can naturally not be validated by a validator. XML Schemas, which are processed at the next opportunity, is a powerful way to express the "constraints" vocabulary creator wants expressed, and fills the same role as a DTD. A DTD describes a "content model" for elements, ie which elements of the hierarchy can be, or should be, "children" to another element. To express that an element "book" can contain exactly one element "title", one of several "authors" zero to one "initial" and zero to several "chapters" can be done by the line <!ELEMENT book (title, author +, introduction?, chapter*)> To further express that a writer has several names, zero to several middle name, and exactly one surname can be done by the line <!ELEMENT author (first-name+, middle-name*, name)> Expressing that the element "book" may have an attribute named "isbn" can be expressed by <!ATTLIST book isbn CDATA #IMPLIED> LinksFor a pre-recorded slidecast (slides + audio) of the second part, see http://www.slideshare.net/bjornh/xml-och-dtd Literature: XML in a nutshell(3) = Essential for the course

Prepare for the lecture by reading thisXSLT is a technology for transforming XML documents belonging to a vocabulary to new XML documents that can belong to the same or an entirely different vocabulary. The patterns and rules about what will happen when the processor finds a certain pattern, described by the element "template" that is defined in the XSLT namespace belongs. The element template has an attribute "match" containing an xpath expression with which to describe the different parts of an XML tree. The content of the template element is then added to the result tree. Content can also include instructions about which nodes will then be contextual nodes. One common case is to allow all or some child nodes become context-nodes by xslt element apply-templates: <xsl:apply-templates select="ett-xpath-uttryck"/> Here is a complete example of a template <xsl:template match="/party/toastmaster/firstname"> The example matches all elements "first name" which is a child element to the "toast master" which in turn is a child element to the "party". If the XSLT processor, in the revision of the input tree, encounters such an element, the first add "<h1> Förnmamn:" the result tree, then go through all the child nodes of the element and see if any rules are applicable to these , to finally close it began h1 element with "</ h1>". ---- Here are the slides from last year's lecture about XSLT . They might be updated. |
