javascript - Remove string after predefined string

I am pulling content from an RSS feed, before using jquery to format and edit the rss feed (string) that is returned. I am using replace to replace strings and characters like so:

var spanish = $("#wod a").text();
var newspan = spanish.replace("=","-");
$("#wod a").text(newspan);

This works great. I am also trying to remove all text after a certain point. Similar to truncation, I would like to hide all text starting from the word "Example".

In this particular RSS feed, the word example is in every feed. I would like to hide "example" and all text the follows that word. How can I accomplish this?

Though there is not enough jQuery, you even don't need it to remove everything after a certain word in the given string. The first approach is to use substring:

var new_str = str.substring(0, str.indexOf("Example"));

The second is a trick with split:

var new_str = str.split("Example")[0];
