Replacing Specific Word / Term In HREF Path

I'm having an issue with doing a simple js task. I have a list of hyperlinks that contain various paths. For instance:
a href="[URL]
a href="[URL]

What I need is to remove the term "content" from all the hyperlinks in it's contain div. There is got to be a simple way of doing this and I can't seem to find the right direction. I also need to have the targets changed as well, which I was able to complete.
window.onload = function(){

var anchors = document.getElementById('containerDiv').getElementsByTagName('a');
var links = "content";
for (var i=0; i<anchors.length; i++){
anchors[i].setAttribute('target', '_blank');
} }
