OT Re: Converting HTML tags into uppercase using Perl

...and, while uppercase tags are allowed under html 4.01, they are NOT allowed in xhtml ~~xml~~ Slap ww upside the head!... so if this is other than homework, steve_g50 may wish to learn a bit more about .html as well as about perl.

Update: Grinder is, of course, correct both re xml and re need to provide cites, and Fletch, thanks! Your cite is bang_on.

uppercase tags [...] are NOT allowed in xml ww may wish to learn more about XML, or least be able to quote the specification chapter and verse in order to back up such a claim. I've been doing XML for years (and SGML before that) and I've never heard of such nonsense. A `start-tag` is a `Name`, and a `Name` is one or more `Letter`s (more or less, ignoring namespace issues), and a `Letter` may be drawn from many, many things, including, but not limited to, uppercase and lowercase letters. See the section on logical structures in the XML specification for more information. Update: my bad, I did ponder how ww could have come up with such an outlandish idea (because his/her advice is spot-on in general), and I failed to make the connection to XHTML. I just wanted to quash the meme before it got any further. • another intruder with the mooring in the heart of the Perl	[reply]

I think he misspoke and meant "XHTML" rather than XML. While you are correct that XML allows upper-, lower-, and mixed-case tag names, the XHTML spec does specifically require lowercase: 4.2. Element and attribute names must be in lower case XHTML documents must use lower case for all HTML element and attribute names. This difference is necessary because XML is case-sensitive e.g. <li> and <LI> are different tags. http://www.w3.org/TR/xhtml1/#h-4.2	[reply]
