If you are a web-standards supporting -- or even just a web-standards aware -- blogger, you probably have a "Valid XHTML" button somewhere on your blog template...
But, after each new post, do you actually take the time to validate the new blog page in order to make sure no typo sneaked in and ruined your otherwise so pure XHTML markup? U-(
Even worse, what happens when an unscrupulous reader leaves a comment, using the best tagsoup he could ever produce in a miserable attempt to make his contribution look better? :no:
Of course, you filter some tags, you probably remove undesired ones, you even close unmatched opening tags... but what do you do when presented with some syntaxic nightmare like
<strong href="junk"> hello <ul> <blockquote> <li> world </strong> ? 88|
There's only one solution: integrate an XHTML validator into your blogtool!
b2evolution does integrate this, starting with version 0.8.2 which will be available shortly!
In the meantime, if you wish, you can try out the validator using the comment field for this post... ;)
