Top Stories by Steve Hoenisch

You've probably heard the propaganda by now: XML blesses you with a way to separate content from presentation. Separation in turn yields productive gains over HTML and other data formats used to manage content. In a process sometimes called single sourcing, the content of an XML document can be formatted for display in a Web browser, reformatted for delivery to such devices as mobile phones and handheld computers, and converted into a PDF file suitable for printing. A news story, for example, that has been marked up in XML can be transformed into HTML for publication on a Web site, converted into Wireless Markup Language (WML) for display on a cell phone's screen, and rendered into a format from which a PDF file can be generated. Meantime, parts of the news story, such as paragraphs that supply background information about a given subject, can be reused in other XML... (more)

Transforming XML Documents into HTML

The power and elegance of XSLT - the Extensible Stylesheet Language for Transformations - stems from its ability to transform XML documents into other output formats like HTML, fulfilling one of the original promises of XML: separating content from presentation. XSLT is particularly powerful because a single stylesheet can format all the XML documents conforming to a DTD into HTML for publication on a Web site. The stylesheet can also be used to automatically generate such features as a hyperlinked table of contents, the building of which requires substantial manual work without... (more)

Declaring Attributes And Entities In DTDs

Introductions to XML all too often ignore the power of the attribute. It gets neglected in favor of the element's ability to capture the structure of a document or the meaning of content. But in developing flexible, reusable document models and in capturing metainformation about structure or content, the attribute's overlooked utility quickly comes into focus. Overlooked, too, have been entities, with few introductions to XML freeing them from their shroud of mystery. They are, however, a powerful method for reusing content or code, both in documents and, as we'll see, in DTDs. To... (more)

DTD Development Driving You Delirious?

No, the abbreviation DTD is not etymologically related to a similar abbreviation from medical science, namely, DTs (or delirium tremens), a violent delirium with tremors, which is induced by the prolonged use of alcohol. Though in absorbing the intricacies of DTDs and trying to develop your first one, you may begin to wonder whether the two terms are somehow connected. Even if you've mastered the basic syntax of XML, writing your first document type definition can be brow-ruffling, not in the least because DTD syntax is different from XML. This tutorial aims to ease you into DTD... (more)

Structuring Documents With XML

This month's tutorial, the second in a series, picks up where last month's left off - on the path toward publishing your résumé on the Internet as an XML document. Last month (XML-J, Vol. 2, issue 5) I presented an overview of XML, described its basic building blocks, and demonstrated how to create a simple XML document. This month, after reviewing XML's fundamental components, I'll guide you through the process of marking up a résumé with XML. In doing so the column touches on the fundamentals of structuring and marking up data as well as some of the concepts - such as hierarch... (more)
