Question

Could you please suggest a platform that could extract webpage data (supporting elements like fields,buttons,links,label,grid data etc.) for webpage data extraction automating like Ruby,Python,C#,etc?

Answer 1

I suggest using the selenium platform. It is a very high quality web automation and supports C#,python,ruby,javascript,java,perl,and php. One of the most important features are that it handles javascript really well.

Selenium Documentation here.

Simple example:

Ruby:

@driver.get("https://demo.aravo.com/")
@driver.find_element(:id, "j_username").clear
@driver.find_element(:id, "j_username").send_keys "sample"
@driver.find_element(:name, "j_password").clear
@driver.find_element(:name, "j_password").send_keys "sample"
@driver.find_element(:name, "login").click
@driver.find_element(:id, "gbqfq").clear
@driver.find_element(:id, "gbqfq").send_keys "ruby fiel format"

Python:

driver = self.driver
driver.get("https://demo.aravo.com/")
driver.find_element_by_id("j_username").clear()
driver.find_element_by_id("j_username").send_keys("sample")
driver.find_element_by_name("j_password").clear()
driver.find_element_by_name("j_password").send_keys("sample")
driver.find_element_by_name("login").click()

C#:

public void TheDriverTest()
{
    driver.Navigate().GoToUrl("https://demo.aravo.com/");
    driver.FindElement(By.Id("j_username")).Clear();
    driver.FindElement(By.Id("j_username")).SendKeys("sample");
    driver.FindElement(By.Name("j_password")).Clear();
    driver.FindElement(By.Name("j_password")).SendKeys("sample");
    driver.FindElement(By.Name("login")).Click();
}
