jQuery does not have a built-in selector to compare the values of
attributes, but it allows you to write custom filters (analogous to
plugins). I once found documentation on this but can't anymore. You
sort of have to read the source to learn to do this.
You just extend the $.expr[':'] object with your new filter set to a
string that is evaluated, where 'a' is the element being tested and
'm[3]' is the argument to the filter:
$.expr[':'].levelGreaterThan = '$.attr(a,"level")>m[3]' ;
Now you can use this anywhere:
$('qualif:levelGreaterThan(3)').remove();
Far more bizarre but potentially useful would be a custom filter that
tests any attribute:
$.expr[':'].attr = 'eval(m[3].replace(/^(\\w+)/,"$.attr(a,\\"$1\
\")"))';
and now write:
$('.qualif:attr(level>3)').remove();
Unfortunately the parser for [attr....] is not extensible, so you
can't create a [level>3] selector directly
