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 = http://www.srcmini.com/inputElement.attr("value"); System.out.println("Param name: "+key+" \nParam value: "+value); } } }

输出：
