Jsoup Example: print form parameters

In this example, we will print form parameters like parameter name and parameter value. To do so, we are calling getElementById() method of Document class and getElementsByTag() method of Element class.

register.html

 <!DOCTYPE html> <html> <head> <meta charset=”utf-8″> <title>Register Please</title> </head> <body> <form id=”registerform” action=”register.jsp” method=”post”> Name:<input type=”text” name=”name” value=”tutor”/><br/> Password:<input type=”password” name=”password” value=”sj”/><br/> Email:<input type=”email” name=”email” value=”tutoraspire1987@gmail.com”/><br/> <input name=”submitbutton” type=”submit” value=”register”/> </form> </body> </html> 

JsoupPrintFormParameters.java

 import java.io.File; import java.io.IOException; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; public class JsoupPrintFormParameters { public static void main(String[] args) throws IOException { Document doc = Jsoup.parse(new File(“e:\register.html”),”utf-8″); Element loginform = doc.getElementById(“registerform”);   Elements inputElements = loginform.getElementsByTag(“input”); for (Element inputElement : inputElements) { String key = inputElement.attr(“name”); String value = inputElement.attr(“value”); System.out.println(“Param name: “+key+” nParam value: “+value); } } } 

Output:

Param name: name  Param value: tutor Param name: password  Param value: sj Param name: email  Param value: [email protected] Param name: submitbutton  Param value: register
