[xsl] space in a url

[Roelof Wobben <rwobben@xxxxxxxxxxx>]

Hello,

I need a url like this :
http://test.tamarawobben.nl/recent-article/2012/04/Zelf bellen

But what I get is
http://test.tamarawobben.nl/recent-article/2012/04/zelf%20bellen

But then I my filter finds nothing because the title is zelf bellen and not
zelf+bellen.

Now I think that @handle can do the job but I don't have a clue how:

What I have is this : <a href =
"{$root}/recent-article/{$year}/{$month}/{$title/@handle}"> test</a>

But that one causes to zelf-bellen instead of zelf bellen.

Can someone give me a tip.
