           if ($("#MyName").val() != '') {
                $.ajax({
                    type: "GET",
                    url: "Xml/Badwords.xml",
                    dataType: "xml",
                    success: function (xml) {

                        $(xml).find('Badwords').each(function () {

                             var flag = true;

                            $(this).children().each(function () {

                                var tagName = this.tagName;
                                var val = $(this).text();

         if (val.toLowerCase() == $("#MyName").val().toLowerCase())                       {
                                    $("#lblMyName").css("display", "block");

                                    $("#lblMyName").text("Please refrain from using profanity.");
                                    $(".postermyname").text('My Name);
                                     flag = false;
                                    return false;                                                                       

                                }

You'll have to split the input value on word boundaries and then compare that against the "bad" words.

Note that profanity filters is in generally a really bad idea, and will usually cause more issues than they solve

if ( $("#MyName").val().trim() != '' ) {
    $.ajax({
        type: "GET",
        url: "Xml/Badwords.xml",
        dataType: "xml",
        success: function(xml) {

            var input = $("#MyName").val().toLowerCase().split(/\b/),
                flag  = true;

            $(xml).find('Badwords').each(function() {
                $(this).children().each(function() {
                    var val = $(this).text().toLowerCase;

                    if (input.indexOf(val) !== -1) {
                        $("#lblMyName").css("display", "block")
                                       .text("Please refrain from using profanity.");
                        flag = false;
                    }
                });
            });
        });
    });
}
