XML/RSS Standards
I've recently been trying my thumb at XML, in particular the RSS standards...

Does anyone happen to know if there's a standard tag and format for date and time of an item?

all of the RSS files i've been using as reference seem to be different...

That's something I've never understood about the world of XML - there's no standard tagging system... or am i missing something?

from my amateur probing of xml, you're right...

although it seems that certain things are applying standards, perhaps for certain industry aspects? i don't know. But i did manage on stumbling across RSS which is a standard for content exchange, mainly use to feed news articles to other websites. Many publications seem to be using it.

even devarticles:
http://www.devarticles.com/rss.php

its fun to look into... i'm hosting my browser homepage with a list of news articles from all my favourite sources...

RSS should have standard tagging names, because all it is is XML for news syndication.

The chemical industry has their own standard set (http://www.xml-cml.org/), and I know that a lot of other major sectors are heading towards their own standardised versions too.

Just got an update from PHPClasses that points to a class somebody's developed to handle a bunch of divergent standards for RSS. I haven't tried it out, but thought the link might go well in here.

Found the following for RSS at http://www.w3.org/2001/10/glance/doc/howto:
Quote:
<span class = "date"> (inside an item): the date of the enclosing item. The date format for all W3C News Feeds should be uniform, please use YYYY-MM-DD


Also, I found
Quote:
All date-times in RSS conform to the Date and Time Specification of RFC 822, with the exception that the year may be expressed with two characters or four characters (four preferred).

XML is not meant to have a standard tagging system, since XML is not a language of it's own. Rather, it's a set of rules, or call it a template, for constructing structured file formats. If you follow the rules, you won't need to write your own parsing routine, but are able to use standard software to parse your file.
