XML is Not a Database

XML is good- but only for some things. XML is very good at describing ordered lists, documents like they will be printed on paper, and simple trees, like family trees. For other things, XML is really bad. All other computer data with a more abstract nature has trouble conforming efficiently to the tree hierarchy of XML. Programs which use XML to describe and retrieve all kinds of data indiscriminately, suffer intense processing delays- particularly while attempting to traverse an ordered list to retrieve unordered data.The strongest feature of XML is that it's very close to the ubiquitous HTML. It's easy for many people to learn about XML because they're used to HTML. Data described by XML can be transformed into HTML very easily.XML works great to describe lists of items, like feeds of syndicated content for things like a news feed, stock quotes, or a series of audio or video episodes. It's great at describing outlines, with bigger sections broken down into smaller an…

A Window Into My Work Day

WARNING: Highly technical stuff ahead. Do not proceed without a pocket protector.Here's a good puzzle for you. How do you use a literal quotation mark in quoted XML text in a string wrapped by the same kind of quotation mark in an XPath query?If you say:
comments[text()="There's a 48" door."]The quotation mark after the 48 ends the text quotation, and the final part of the string (" door.",) is unexpected, and causes a syntax error. Simple enough so far, right?A literal quotation mark in an XPath string is NOT automatically escaped to it's character entity to indicate a literal quotation mark. Instead, it's naturally used as part of the XPath code, to break the XPath string.Your first impulse might be to switch quotation mark types. I disdain the switching of quotation mark types. In my opinion, the double quotation mark should always be used to indicate a string quotation, and if it must be escaped, it should be escaped. Some people prefer to u…

Sample Manual

I like to create my web pages in plain text editors. Here's a good template to start a new web page. I like the filename, "index.htm".
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
 "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us">
 <head>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
  <title>Fun Work</title>
  <style type="text/css">
  /* <![CDATA[ */
   h1{text-align:center;}

  </style>

Standard Page Format

Web pages are an extremely useful format for many different purposes. If possible, I think it's best to stick to the most widely used standards.This format may be UTF-8 encoded, Strict XHTML 1.1 with CSS1. The file may contain an American English (en-US) web page, valid in the strict XHTML 1.1 language, encoded in UTF-8. It may also contain a fun visual style for the page, in the CSS1 language.Entire jobs may be distributed in single ZIP files. The zip may contain web pages and atom feeds. An atom feed can include a good record of the whole project.Share your comments!

How to Have Fun at Work
