JQuery :: Show And Hide Rows With Matching ID's?

I have a script that prints out a lot of <tr>'s, each has a different id, let's say it's a number. What i am trying to get is when a user enters numbers in a certain textfield, named #idtext for example, it shows only those <tr>'s whose id numbers matches the entered value and hides the rest. For example, user enters 23 in the text field, rows with id numbers 123, 23, 231 are shown, the rest are hidden, etc.

Atm i have smoething like this, not working:

$("#idtext").change(function(){
var val = $("#idtext").val();
$('tr[id^<>'+val+']').hide();
$('tr[id^='+val+']').show();
});
