  • Parsing text with proHtml and printing random words to the screen
    Hi,

    I am running into some trouble with printing random words (using text()) found in parsing an html file. I can use println(), and actually get it to work; however, I want to display text on a different screen instead. 

    The error that I'm getting is 'The method text(String, float, float) in the type PApplet is not applicable for the arguments (String)'. I know that I need to convert my float (or is it an int) to a string somehow, but I have so much info going on that I can't easily find a solution. I would be very grateful if anyone can give me a solution!

    Here's the code:

    import prohtml.*;
    import java.util.regex.*; 

    PrintWriter txtfile;
    HtmlList htmlList;
    PFont myFont;

    void setup(){
      size(500,500);
      background(255);
      myFont = createFont("Rockwell", 48);
      textFont(myFont);
      frameRate(10);
      //enter your url here
      htmlList = new HtmlList("http://en.wikipedia.org/wiki/Life");
      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("[L|l]ife\\s[A-Za-z]+\\s[A-Za-z]+");
      Matcher n = q.matcher(s_list);
      
      String word_list[] = split(s_list, ' ');
      saveStrings("html_input.txt", word_list);
    }

    void draw() {
      String[] words = loadStrings("html_input.txt");
      int pastIndex = int(random(words.length));
      int presentIndex = int(random(words.length));
      int futureIndex = int(random(words.length));
      println(words[pastIndex]);
      String past = (words[pastIndex]);
      textAlign(CENTER, TOP);
      text(past);
      //textAlign(CENTER, CENTER); 
      //text(words[presentIndex]);
      //textAlign(CENTER, BOTTOM);
      //text(words[futureIndex]);
    }
