I developed the following código to take the content of a given web page:

import java.util.logging.Logger;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
Logger logger= Logger.getLogger("org.bonitasoft");

URL url = null;
File file = new File("C:\\Backup\\page.html");

def x = 1;
//while (x = 1){
    url = new URL("http://site");

    BufferedReader inFile = new BufferedReader(new InputStreamReader(url.openStream()));
    BufferedWriter outFile = new BufferedWriter(new FileWriter(file));
    String inputLine;

    while ((inputLine = inFile.readLine()) != null) {
        Matcher matcherRamo = Pattern.compile("Ramo:\\s<.strong>\\s.*").matcher(inputLine)
        Matcher matcherNome = Pattern.compile("consulta-associados-item-nome-fantasia").matcher(inputLine)
        Matcher matcherFone = Pattern.compile("<strong>Fone: <.strong>").matcher(inputLine)
        Matcher matcherEmail = Pattern.compile("<strong>Email: <.strong> <a href=\"mailto:.*\" class=\"link\">").matcher(inputLine)
        Matcher matcherProduto = Pattern.compile("<span class=\"float-left\">").matcher(inputLine)
        Matcher matcherSite = Pattern.compile("<strong>Site: <.strong>\\s<a href=.* target=\"_blank\">").matcher(inputLine)

        if (matcherNome.find()){
            logger.info("NOME: "+inputLine.replace("<h3 class=\"consulta-associados-item-nome-fantasia\">", "").replace("</h3>", "").trim())
        }
        if (matcherFone.find()){
            logger.info("TELEFONE: "+inputLine.replace("<strong>Fone: </strong>", "").trim())
        }
        if (matcherEmail.find()){
            logger.info("EMAIL: "+inputLine.replaceFirst("<strong>Email: <.strong> <a href=\"mailto:.*\" class=\"link\">", "").replace("</a>", "").trim())
        }
        if (matcherRamo.find()){
            logger.info("RAMO: "+inputLine.replace("Ramo: </strong> ", "").replace("<strong>", "").trim())
        }
        if (matcherProduto.find()){
            logger.info("PRODUTO: "+inputLine.replace("<span class=\"float-left\">", "").replace("</span>", "").replace("<br>", " | ").trim())
        }
        if (matcherSite.find()){
            logger.info("SITE: "+inputLine.replaceFirst("<strong>Site: <.strong>\\s<a href=.* target=\"_blank\">", "").replace("</a>", "").trim())
        }

        outFile.write(inputLine);
        outFile.newLine();
    }
    //x++
//}
inFile.close();
outFile.flush();
outFile.close();

He is correctly picking up the information I need but when the process is finished, finished reading the entire page and returned me the filtered content he starts to do again the same thing, infinitely, if you can help me thank.

java loop groovy

  • Just out of curiosity, what is/does def x = 1;?

  • 1

    @Igorventurelli It was an unsuccessful test kk

  • Put the complete code.. There is no definition of class or method.. It is difficult to understand hehe

  • @Igorventurelli this is the complete code, I have nothing else

  • There’s... there’s not one public class Classe { } ._. That’s right?

  • 1

    @Igorventurelli, I’m sorry, I forgot to add to tag groovy, I put the Java for being extremely similar but it’s a groovy script

  • Let’s go continue this discussion in chat.

I solved my question as follows:

import java.nio.charset.StandardCharsets;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.util.logging.Logger;
Logger logger= Logger.getLogger("org.bonitasoft");

URL url = null;
def y = 1
def lista = []
BufferedWriter strW = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:\\TESTE\\teste.csv"), StandardCharsets.ISO_8859_1));
lista.add("EMPRESA;TELEFONE;EMAIL;RAMO;PRODUTO;SITE\n")

    url = new URL("http://site");
    BufferedReader inFile = new BufferedReader(new InputStreamReader(url.openStream()));
    String inLine;
    if (!inFile.toString().isEmpty()){
        while ((inLine = inFile.readLine()) != null) {
            Matcher matcherRamo = Pattern.compile("Ramo:\\s<.strong>\\s.*").matcher(inLine)
            Matcher matcherNome = Pattern.compile("consulta-associados-item-nome-fantasia").matcher(inLine)
            Matcher matcherFone = Pattern.compile("<strong>Fone: <.strong>").matcher(inLine)
            Matcher matcherEmail = Pattern.compile("<strong>Email: <.strong> <a href=\"mailto:.*\" class=\"link\">").matcher(inLine)
            Matcher matcherProduto = Pattern.compile("<span class=\"float-left\">").matcher(inLine)
            //Matcher matcherServicos = Pattern.compile("<strong>Atividade: <.strong>").matcher(inLine)
            Matcher matcherSite = Pattern.compile("<strong>Site: <.strong>\\s<a href=.* target=\"_blank\">").matcher(inLine)
            Matcher matcherNewLine = Pattern.compile("<!-- .consulta-associados-item-infos-right -->").matcher(inLine)
            if (matcherNome.find()){
                lista.add(inLine.replace("<h3 class=\"consulta-associados-item-nome-fantasia\">", "").replace("</h3>", "").trim()+";")
                //logger.info(inLine.replace("<h3 class=\"consulta-associados-item-nome-fantasia\">", "").replace("</h3>", "").trim()+";")
            }
            if (matcherFone.find()){
                lista.add(inLine.replace("<strong>Fone: </strong>", "").trim()+";")
                //logger.info(inLine.replace("<strong>Fone: </strong>", "").trim()+";")
            }
            if (matcherEmail.find()){
                lista.add(inLine.replaceFirst("<strong>Email: <.strong> <a href=\"mailto:.*\" class=\"link\">", "").replace("</a>", "").trim()+";")
                //logger.info(inLine.replaceFirst("<strong>Email: <.strong> <a href=\"mailto:.*\" class=\"link\">", "").replace("</a>", "").trim()+";")
            }
            if (matcherRamo.find()){
                lista.add(inLine.replace("Ramo: </strong> ", "").replace("<strong>", "").trim()+";")
                //logger.info(inLine.replace("Ramo: </strong> ", "").replace("<strong>", "").trim()+";")
            }
            if (matcherProduto.find()){
                lista.add(inLine.replace("<span class=\"float-left\">", "").replace("</span>", "").replace("<br>", " | ").trim()+";")
                //logger.info(inLine.replace("<span class=\"float-left\">", "").replace("</span>", "").replace("<br>", " | ").trim()+";")
            }
            if (matcherSite.find()){
                lista.add(inLine.replaceFirst("<strong>Site: <.strong>\\s<a href=.* target=\"_blank\">", "").replace("</a>", "").trim()+";")
                //logger.info(inLine.replaceFirst("<strong>Site: <.strong>\\s<a href=.* target=\"_blank\">", "").replace("</a>", "").trim()+";")
            }
            if (matcherNewLine.find()){
                lista.add("\n")
            }
        }
        y++
    }
    inFile.close();

//logger.info(lista.toArray().toString().replace("[", "").replace("]", "").replace(",", ""))
strW.write(lista.toArray().toString().replace("[", "").replace("]", "").replace(",", ""))
strW.close();
