//the idea here is to create "tokens" or keywords. so we're going to seperate every word in the sentance and put it in an array tokens. and pass it over to //parseXML. so a string of "the quick brown fox jumped over the lazy dog" would become:
//	tokens[0] = "the"
//	tokens[1] = "quick"
//	tokens[2] = "brown"
//	tokens[3] = "fox"
//	tokens[4] = "jumps"
//	tokens[5] = "over"
//and the rest is truncated
