Again, I say that it won't work on URLs with spaces, like "my web

weren't valid markup, but it seems to validate.
Some small points of information:
An HTML4 validator will only check that a HREF value is CDATA, as
required by the DTD:
http://www.w3.org/TR/REC-html40/struct/links.html#adef-href
http://www.w3.org/TR/REC-html40/sgml/dtd.html#URI
http://www.w3.org/TR/REC-html40/types.html#type-cdata
Plenty of things can be CDATA without being a valid URI:

Space characters (U+0020) that are not percent encoded are not valid in
a URI:
http://gbiv.com/protocols/uri/rfc/rfc3986.html#collected-abnf
That's not to say that browsers haven't developed error handling for
space characters (and other illegal characters) in HREF values.
The HTML5 draft proposes an algorithm for parsing and resolving HREF
values that includes such error handling:
