Thanks! Tried var here = $("#Navigation li a[href='+Path+']"); and var here = $("#Navigation li").$("a[href='+relPath+']"); (Are they totally equal?) still gives me nothing.
I'm not very trained in javascript/jQuery but I thing you misunderstood my line 1 and 2. relPath is for the relative path -without the http-domain-prefix (my navigation tree is with relative urls) The http-domain-prefix is either on my local machine or on my site- domain. I've checked out the docs, but the use of quotes given here throws out an error in my Firebug: http://docs.jquery.com/Selectors/attributeEquals#attributevalue
