Daily newness: An online XML-to-XSD Converter

OK, most of you probably don’t know the difference between an XML file and an XSD (“XML Schema”) file. For a brief intro check out W3Schools’ XML Schema tutorial. A brief quote: “The purpose of an XML Schema is to define the legal building blocks of an XML document, just like a DTD.”

This week I needed to create an XML Schema doc for work. The XSD file would be used to validate XML files I’ll be making for my online courses. Well, being a newbie to XSD files (though not XML), I was making decent but very slow progress when a thought occurred to me: it should be possible to reverse-engineer an XML file to create an XSD file. And, considering how prevalent XML is these days, someone probably posted an online converter for it! Google to the rescue!

I found a number of tools (mostly software downloads such as XMLSpy), but the easiest one I’ve tried so far is by — gulp — the Evil Empire itself: Microsoft.

All I can say is whether you love ’em or hate ’em, their tool works great and is completely free. On my first try it pointed out some invalid XML I had written. After correcting my mistake, BAM!, I had a complete XSD file. It wasn’t perfect and needed some tweaking (optional versus required tags, string v. integer, etc.), but it eliminated most of the heavy lifting for me and I’ll be finished a heck of a lot sooner than I would have been without it.

Umm… thanks, Microsoft! (For once…)

Today’s bit o’ knowledge: Firefox Web Developer Extension

today i learned about chris pederick’s ultra-handy Web Developer Extension for Firefox. yeah yeah yeah, i know it’s been around for a while, but i never TRIED it until today. i wish i had tried it sooner!

among its many features is the ability to toggle outlines on and off (looking at other sites’ block-level CSS is fun in a voyeuristic way), as well as the ability to disable a site’s CSS, images, javascript, cookies and more! it makes it really easy to examine the nuts-and-bolts of a web page’s structure/design without doing a save-as and opening in an editor like dreamweaver. me likey mucho.
