filter out jquery loop

[ggalan]

i have a jquery loop that looks like this.

var tagsArr=new Array();
$('.thumb_tag').each(function(){
        var htmlStr = $(this).html();
        $(htmlStr).find('a').each(function(){
            tagsArr.push($(this).html().toLowerCase());
			
        });
    });

the line: tagsArr.push($(this).html().toLowerCase());
will find all 'a' elements of this loop and display it

my question:
how can i set a "filter" so that i can do something like this

  if ($(htmlStr).find('a').match(/\bdesign\b/)){ // the \b is a word boundary and the word i want to only output is design
    tagsArr.push($(this).html().toLowerCase());
  }

in other words, if the element inside 'a' is

<a>design</a>

then perform this function

 tagsArr.push($(this).html().toLowerCase());

tried this, but no luck

 $('.thumb_tag').each(function(){
        var htmlStr = $(this).html();
        // $(htmlStr).find('a').each(function(){
       var itm =  $(htmlStr).find('a').each( function(){
            

     if (itm.innerHTML == "design"){
    tagsArr.push($(this).html().toLowerCase());

     }
            
        });
    });
