.each loops through all elements which matches a specific selector. If the code below is not sufficient, change the selector ("td.ms-formbody") such that your desired elements are matched.

$("td.ms-formbody").each(function(){ /* Should walk through all elements */
var val = $(this).text().replace(/\s|\xA0/g,'');
    if($(this).parents().html().match('FieldName="#H#')==null){
        if(val.length==0){
            $(this).parents('tr:first').hide();
        }
    }
});

If you’re still stuck, provide your HTML code, so that a more specific answer can be offered.
