Javascript replace from to

I found good tutorials on how to do a string replace all for a string, but how to replace from a to b ?

Lets say we have this selector

$('a.mylink')

This selector will return something like

<a class=​"micro_avatar my_avatar">​</a>​ 
<a href=​"#!/​users/​user_name" style=​"background:​ 
  url(https:​/​/​secure.gravatar.com/​avatar/​randomnumber?size=24&default=mm)​ 
  no-repeat" class=​"micro_avatar">​</a>​
http://www.youtube.com/watch?v=_sgu7CioctU

In the page that Im testing this, will find multiple ocurrences of this w variations ( imagine a blog and each post have this inside).

Now we want to replace all the ocurrences to look like this

<a class=​"micro_avatar my_avatar">​</a>​ 
<a ** rel='nofollow' ** href=​"#!/​users/​user_name" style=​"background:​ 
  url(https:​/​/​secure.gravatar.com/​avatar/​randomnumber?size=24&default=mm)​ 
  no-repeat" class=​"micro_avatar">​</a>​

**<iframe width="560" height="315" src="** http://www.youtube.com/embed/_sgu7CioctU
**" frameborder="0" allowfullscreen></iframe>**

The trick part is not all the youtube links will have the same link.

Use Javascript substr 

var result = 
    val.substr(a, b);
