How to read a String, char by char at a time

Hi,
I'm sort of stuck on this. So I want to be able to read an ongoing live (twitter feeds) String, char by char and once it reads a char have it specifically do an action.
I have the parsing of the twitter String, but I'm stuck on reading each character individually and doing an action afterward. If someone could suggest anything, I'd really appreciate it! Thanks.
Here's my code:

Here's my code:

font = createFont("Arial-Bold.vlw", 70);
textFont(font);
textAlign(LEFT);
ellipseMode(CENTER);
//Styles
imageMode(CENTER);
smooth();
//Tweets
fill(254,49,30);
textFont(font, 20);
//Search
XMLElement rss = new XMLElement(this,
"http://search.twitter.com/search.atom?q=search&show_user=true");
XMLElement tweets[] = rss.getChildren("entry/title");
strTweets= new String[tweets.length];
for(int i = 0; i < tweets.length; i++) {
strTweets[i] = tweets[i].getContent();
}
}
void draw() {
switch (nextPage) {
case 0://Splash Page
background(255,253,245);

void tweets () {//Scroll Tweets
