Regex question--works in the regex tester but not in processing

I am trying to pull names off of a website--the names are all in caps so it seemed like it would be easy but I am getting a lot of extra text. I tested a solution that worked great in http://regexpal.com, but will not work in processing

here is my regex equation

"(?!LOW)([A-Z][A-Z][A-Z]+)"

I want words that are all caps, three letters or longer, and not the word LOW

What I am getting are lots of single letters (probably pulled from the start of sentances) and the word LOW

Here is my code:

import prohtml.*;

import java.util.regex.*;

PrintWriter txtfile;

HtmlList htmlList;

void setup(){

size(100,100);

//enter your url here

htmlList = new HtmlList("http://nuclearweaponarchive.org/Usa/Tests/Nevada.html");

String s_list = "";

for (int i = 0;i<htmlList.pageList.size();i++){

String s = htmlList.pageList.get(i).toString();

Pattern p = Pattern.compile("<");

Matcher m = p.matcher(s);

boolean found = m.find();

if (found == false){

s_list = s_list.concat(s + " ");

}

}

println(s_list);

Pattern q = Pattern.compile("^KT[A-Z]&&[A-Z]&&[A-Z]+");

Matcher n = q.matcher(s_list);

int numMatches = 0;

// load existing text into memory

String lines[] = loadStrings("nuclear_match.txt");

txtfile = createWriter("nuclear_match.txt");

for(int i=0;i<lines.length;i++){

txtfile.println(lines[i]);

}

while(n.find() == true){

String h = n.group();

txtfile.println(h);

numMatches++;

}

txtfile.flush();

txtfile.close();

println("results: " + str(numMatches));

String word_list[] = split(s_list, ' ');

saveStrings("html_input.txt", word_list);

}
