TextFinder Woes

Projects Programming

Hi everyone,

I've been playing around with the TextFinder library and seem to have hit a wall. The project is supposed to pull text from an rss feed and if it sees one of the keywords, it makes a servo move. The problem I encounter occurs only when a keyphrase that is not yet present is before one that is already in the feed. This results in TextFinder telling me that none of my keyphrases are present even if they are.

if (client.connected()) {
    for (int i = 0; i < 4; i++) {    // for loop iterates through keyphrase array
      Serial.println("for loop");    // making sure the loop iterates from 0-3, which it does
      Serial.println(i);
      if (finders[i].find(myPhrases[i])  ) {    // text finder for parsing xml data for keyphrases
        Serial.print("Phrase ");
        Serial.print(myPhrases[i]);    //making sure the phrases iterate, which they do
        Serial.println(" has been found");
        
        myPhrases[i] = 0;    // nulls the array entry
        servos[i].write(0);    // moves the servo to desired position
        servos[i].detach();    // detaches the servo from the pin
      }
      else {
        Serial.println(i);
        Serial.println(myPhrases[i]);    //another check to make sure the phrases iterate, which they do
        Serial.println("no phrase found");
      }
      delay(1000);
    }
    Serial.println("Disconnected");
  }
  client.stop();
  client.flush(); 
  delay(3000); // wait 3 seconds before next update
}

The code above shows my attempt at creating four different finder instances and iterating through them as well but to no avail. Even when the first phrase is present, TextFinder only seems to recognize one correct phrase per for loop, meaning that if the first and last phrases (0 and 3) are present, I receive 16 iterations instead of both of them just being recognized in the first loop. Anyone have any idea what I'm doing wrong?

Without being clear on the effects of multiple stream objects (I'm learning as I go along), my approach here to test would be to initialise the connect and stream within the loop.

TextFinder finder(client);
boolean textFound = false;
for (int i = 0; i <4; i++) {
	if (client.connected()) {
		if (finder.find(myPhrases[i])) {
			Serial.print("Phrase ");
			Serial.print(myPhrases[i]);
			Serial.println(" has been found");
			
			myPhrases[i] = "";
			servos[i].write(0);
			servos[i].detach();
			textFound = true;
		}
		client.stop();
		client.flush();
	}
}

if (!textFound) {
	Serial.println("No phrase found");
}

delay(3000);

Reconnecting each iteration will (I think) reinitialise the stream and thus, logically, the search function will work.
