Are you looking for info like the following?
input: <a href=" http://www.example.com/√/with spaces/script
name.ext?uni=√&with spaces=with spaces ">test</a>
Here's the output in different browsers. (.href first and then
.getAttribute("href"))
Opera:
"http://www.example.com/√/with%20spaces/script%20name.ext?uni=%E2%88%9A&with%20spaces=with%20spaces"
" http://www.example.com/√/with spaces/script name.ext?uni=√&with
spaces=with spaces "
IE:
"http://www.example.com/√/with%20spaces/script%20name.ext?uni=√&with
spaces=with spaces"
"http://www.example.com/√/with%20spaces/script%20name.ext?uni=√&with
spaces=with spaces"
Firefox:
"http://www.example.com/%E2%88%9A/with%20spaces/script%20name.ext?uni=%E2%88%9A&with%20spaces=with%20spaces"
" http://www.example.com/√/with spaces/script name.ext?uni=√&with
spaces=with spaces "
Safari:
"http://www.example.com/%E2%88%9A/with%20spaces/script%20name.ext?uni=%E2%88%9A&with%20spaces=with%20spaces"
" http://www.example.com/√/with spaces/script name.ext?uni=√&with
spaces=with spaces "
For .href,
Leading and trailing raw spaces are stripped in all 4 browsers.
Raw spaces in directory names are converted to %20 in all 4.
Raw spaces in hvalues and hnames are converted to %20 in Opera,
Firefox and Safari, but not IE.
Wide characters in hvalues and hnames are converted to their
corresponding %HH sequence in Opera, Firefox and Safari, but not IE.
Wide characters in directory names are converted to their
corresponding %HH in Firefox and Safari, but not in IE and Opera.
For getAttribute,
Firefox, Opera and Safari give the actual value as it was in the
source. IE gives the same (at least in this case) as .href.
There are other things to check like leading and trailing raw spaces
in directory names and in hvalues and hnames because those might get
stripped by some browsers also.
Btw, if you look at the source of <
http://revision3.com/diggnation/2008-01-31tokenuser/ >, you'll see
that the Thumb and File hvalues in the embed src URIs are not escaped
properly, which is also the case for the markup they give others to
embed on their own site.
