Here you have an example of how you can do it using p tags and jQuery. Hope it helps
var thePhrase = "this is the phrase to replace";
var toReplace = "this is the phrase that replaces thePhrase";
$("p").each(function(){
var $this = $(this);
if( $this.html() == thePhrase) {
$this.html( toReplace );
}
});
See a demo of it here http://jsfiddle.net/sousatg/w3jCj/
