jQuery find and replace string

Question

I have somewhere on website a specific text  let s say  lollypops   and I want to replace all the occurrences of this string with  marshmellows   The problem is that I don t know where exactly the text is  I know I could do something like     body  html   body  html   replace  lollypops    marshmellows       This would probably work  but I need to rewrite as little HTML as I can  so I m thinking something like    search for the string find the closest parent element rewrite only the closest parent element replace this even in attributes  but not all  for example replace it in class  but not in src   In example  I would have structure like this   lt body gt       lt div gt           lt div gt               lt p gt                  lt h1 gt                    lt a gt lollypops lt  a gt                  lt  h1 gt               lt  p gt               lt span gt lollypops lt  span gt           lt  div gt       lt  div gt       lt p gt          lt span class  lollypops  gt Hello  World  lt  span gt          lt img src   lollypops jpg  alt  Cool image    gt       lt  p gt   lt body gt    In this example  every occurrence of  lollypops  would be replaced  only  lt img src      would remain the same and the only elements that would actually be manipulated would be  lt a gt  and both  lt span gt s  Does anybody know how to do this

Why you just don t add a class to the string container and then replace the inner text   Just like in this example   HTML    lt div gt       lt div gt           lt p gt              lt h1 gt                lt a class  swapText  gt lollipops lt  a gt              lt  h1 gt           lt  p gt           lt span class  swapText  gt lollipops lt  span gt       lt  div gt   lt  div gt   lt p gt      lt span class  lollipops  gt Hello  World  lt  span gt      lt img src   lollipops jpg  alt  Cool image    gt   lt  p gt    jQuery     document  ready function             swapText   text  marshmallows

You could do something like this      span  p   each function         var text     this  text        text   text replace  lollypops    marshmellows          this  text text         It will be better to mark all tags with text that needs to be examined with a suitable class name   Also  this may have performance issues  jQuery or javascript in general aren t really suitable for this kind of operations  You are better off doing it server side
