Assemble a Cross-Platform Firefox Extension

XUL is a surprisingly easy way to build cross-platform browser extensions or even stand-alone applications. Discover how to build powerful, flexible Mozilla browser extensions that go beyond the capabilities of other tools like embedded scripting languages or CGI--because they're built right into the user's browser.

Fast Incremental Updates of XML Records

XML is often used today as a data export and exchange format. In such cases, you might deal with a feed of XML records; sometimes, if this feed, is too long, there are performance problems importing it into another system. As such, you might want to produce only an incremental feed--that is, one that only includes items that have changed. This article presents a collection of simple techniques that you can combine into a system for more digestible feeds containing only updated records.

Quick and Dirty Web Applications with Bookmarklets

Web 2.0 is well known for the fact that it's not built on breathtaking new inventions, but rather on renewed emphasis on age-old Web technologies. One of those age-old technologies that is enjoying a revival in Web 2.0 is bookmarklets. A bookmarklet is essentially a Web application shoehorned into a regular browser bookmark. This article includes a fully functioning bookmarklet and installation instructions you can use to highlight text on any Web page and search IBM developerWorks for that text.

Rescue Terrible HTML with TagSoup

XHTML is a friendly enough format for parsing and screen-scraping, but the Web still has a lot of messy HTML out there. In this tip Uche Ogbuji demonstrates the use of TagSoup to turn just about any HTML into neat XHTML.

Semantic Anchors for XML

XML syntax is just the foundation for data interoperability. The next step is semantic transparency. Some groups are working to address this by defining entire document formats to be adopted wholesale, while other groups are working on ways to express common terminology and concepts at a more granular level. In this installment, Uche Ogbuji looks at XML Topic Maps Published Subjects and Universal Data Element Framework (UDEF), two ideas that take the granular approach by seeking to provide anchors in the semantic stream.

A Survey of XML Standards: Part 1

The world of XML is vast and growing, with a huge variety of standards and technologies that interact in complex ways. It can be difficult for beginners to navigate the most important aspects of XML, and for users to keep track of new entries and changes in the space. In this series of articles, Uche Ogbuji provides a guide to XML standards, including a wide range of recommended resources for further information.

Use Data URIs to Include Media in XML

There are many ways to link to non-XML content within XML, including binary content. Sometimes you need to roll all such external content directly into the XML. Data scheme URIs are one way to specify a full resource within a URI, which you can then use in XML constructs. In this tip, Uche Ogbuji shows how to use this to bundle related media into a single file.

Use Language-Specific Tools for XML Processing

DOM and SAX are the two best known systems for XML processing, but they are really compromises across programming languages. As such, they do not take advantage of any language's particular strengths. Often it is better to duck conventional wisdom and use special APIs that take advantage of particular strengths.

Use the Unicode Database to Find Characters for XML Documents

The Unicode consortium is dedicated to maintaining a character set that allows computers to deal with the vast array of human writing systems. When you think of computers that manage such a large and complex data set, you think databases, and this is precisely what the consortium provides for computer access to versions of the Unicode standard. The Unicode Character Database comprises files that present detailed information for each character and class of character. The strong tie between XML and Unicode means this database is very valuable to XML developers and authors. In this article Uche Ogbuji introduces the Unicode Character Database and shows how XML developers can put it to use.
