I'm trying to navigate in site: http://startupnationbook.com/startup-map
I want to click on link of Startups, however I'm not able to locate the element.
I tried:
elem = driver.findElement(By.xpath("//a[contains(text(),'Startups')]"));
and
elem = driver.findElement(By.xpath("//*[#id='listtoggle' and contains(text(),'Startups')]"));
In both cases I get: "Unable to locate element" error
What is wrong in my expressions and how can I locate the element to perform a click.
The map is in an iframe, you're probably not telling Selenium to look in there. I would also look for the span tag, and since the id listtoggle is used many times (poor design, making it worthless), just look for contains Startups.
// Also should probably use a wait here, in case the page takes too long to load
chromeDriver.switchTo().frame(chromeDriver.findElement(By.tagName("iframe")));
WebElement elem = chromeDriver.findElement(By.xpath("//span[contains(text(),'Startups')]"));
You can do like below :
WebDriver driver = new FirefoxDriver();
driver.get("http://startupnationbook.com/");
driver.findElement(By.xpath(".//*[#id='main-nav']/li[5]/a")).click();
Hope this will work. I have tested.

I am new to programming and extremely new to web scraping. I need to scrape a table from a web page, where the table is displayed after a video.
As I said on the title, I tried implicit waits like:
driver.implicitly_wait(40)
...
inputElement = driver.find_element_by_class_name("_td")
(I tried the same with the xpath)
and explicit waits:
wait = WebDriverWait(driver, 40)
wait.until(EC.visibility_of_element_located(By.XPATH("path...")
(tried the same with class name)
This is what I get:
NoSuchElementException: Message: no such element: Unable to locate element
I would REALLY appreciate your help!
There is an iframe we need to switch to so do this prior to looking for your elements.
iframe = driver.find_element_by_tag_name('iframe')
driver.switch_to.frame(iframe)
I am doing project on different crawlers and trying to mimic user actions. As part of it, I am crawling this url. Here there is a zip code box and I am trying to click on it and extract text from the drop down which will appear after that. I wrote the below code but not sure why it is not working at all. Can anyone please help? I did exhaustive search to find root cause but got nothing. Any suggestions would be much much appreciated.
driver.getUrl(aboveUrl);
WebElement inputBox = driver.findElement(By.id("pincodeInputId"));
inputBox.click();
System.out.println(driver.findElement(By.className("_3mWImx")).getText());
-- This gives null;
Awaiting help !
The reason is the node that you picked is the parent node of the element that has the text
You should use
System.out.println(driver.findElement(By.css("_3mWImx span")).getText());
And that would work. Also note that there are multiple element with the class _3mWImx, so this will only give you the first one. If you are interested in all of them, then you should be using driver.findElements and looping through the result
Actually there are more than one values in the drop down if you want to print all you have to used findElements(). Use this code it will give you desired result :
WebDriver driver=new FirefoxDriver( );
driver.manage().window().maximize();
driver.get("https://www.flipkart.com/moto-e4-plus-fine-gold-32-gb/p/itmevqynuz4fwxca");
WebElement inputBox = driver.findElement(By.id("pincodeInputId"));
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
inputBox.click();
List<WebElement> elements=driver.findElements(By.className("_3mWImx"));
for(WebElement ele:elements)
{
System.out.println(ele.getText()); //It will print innertext of each element
}

I am not able to click on 'Albums' in Facebook.
The HTML is Albums how to locate the element 'Albums' in selenium web driver.
I tried with using driver.findelement(By.xpath(span[#class="_3sz"]) showing error as element not found
And, the html looks the following:
<span class="_3sz">Albums</span>
If I am understanding your problem correctly then that xpath you mentioned returns more than one elements. Use a text based search which is more easier and specific.
driver.findelement(By.xpath("//*[.='Albums']").click();
And, here . is used to directly point to the parent element. Additional wait might be needed to wait for the element to interact. Also, I am assuming you are trying to click the element.
EDIT
Driver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(10));
Driver.Navigate().GoToUrl("http://www.facebook.com");
Driver.Manage().Window.Maximize();
Driver.FindElement(By.CssSelector("#email")).SendKeys("your email");
Driver.FindElement(By.CssSelector("#pass")).SendKeys("your pass");
Driver.FindElement(By.CssSelector("[type='submit'][value='Log In']")).Click();
Driver.FindElement(By.CssSelector(".fbxWelcomeBoxName")).Click();
Driver.FindElement(By.XPath("//*[.='Photos']")).Click();
wait.Until(ExpectedConditions.ElementIsVisible(By.XPath("//*[.='Albums']")));
Driver.FindElement(By.XPath("//*[.='Albums']")).Click();
By albumname = By.XPath("//strong[.='2014']"); //this should be your album name. In my case it's 2014
wait.Until(ExpectedConditions.ElementExists(albumname));
Driver.FindElement(albumname).Click();
wait.Until(ExpectedConditions.ElementExists(By.CssSelector(".fbPhotoAlbumHeader.fbPhotoAlbumOptionsPresent [type='file']")));
Driver.FindElement(By.CssSelector(".fbPhotoAlbumHeader.fbPhotoAlbumOptionsPresent [type='file']")).SendKeys(#"D:\Users\Saifur\Desktop\FacebookPicture\150232_585410621540701_1836495431_a.jpg");
wait.Until(ExpectedConditions.ElementExists(By.CssSelector(".pvm.phl.footerBox.uiBoxWhite")));
Driver.SwitchTo().ActiveElement();
wait.Until(ExpectedConditions.ElementExists(By.CssSelector("[name='postPhotosButton']")));
Driver.FindElement(By.CssSelector("[name='postPhotosButton']")).Click();
Notice mine is C#
It always best practice to follow this sequence while selecting elements.
1) ID
2) CSS
3) XPath (This will have some issues with different browsers specially IE)
In this case, considering this is no other span class with same name. It would have work like this "span._3sz". Simple and powerful.
Initially I tried with below code:
WebElement admin = driver.findElement(By.xpath("//a[text()='Users']"));
and then also with
WebElement usrs = driver.findElement(By.xpath("//html/body/div[2]/div[3]/div[1]/form/div[4]/div[2]/div[1]/a[linktext()='Users']"));
The above codes didn't identify the object (link) in web page.
Please help me to resolve this issue.!
Try for the first 'a' element containing 'Users'.
WebElement admin = driver.findElement(By.xpath("//a[contains(text),'Users']"));
or for exact match
WebElement admin = driver.findElement(By.xpath("//a[.='Users']"));
and
"//body/div[2]/div[3]/div[1]/form/div[4]/div[2]/div[1]/a[contains(text),'Users']"
If you're going the xpath route, make it easy on yourself. Inspect element with Chrome then right click on the element in the chrome console and "copy xpath". That will give you the exact xpath and you don't have to worry about any "contains" or anything else. That's what the [1] is for.
I was working on reading mails from gmail using webdriver and in between I hit upon this difference between By.id and By.tagname.
I am trying to get access to a "table" whose id is ":pg". So I could
Either use By.id(":pg")
OR use By.tagname("table") and search for an element with id :pg
Here is the code for both cases.
By.id:
WebDriver webDriver = new FirefoxDriver();
webDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
webDriver = webDriver.switchTo().frame("canvas_frame");
WebElement table1 = webDriver.findElement(By.id(":pg"));`
Above code, I directly get the element which has id ":pg"
By.tagname:
WebDriver webDriver = new FirefoxDriver();
webDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
List<WebElement> tables = webDriver.findElements(By.tagName("table"));
for(WebElement table2: tables){
String id = table2.getAttribute("id");
System.out.println("id: "+ id);
if(id != null && id.equals(":pg")){
System.out.println("FOUND IT!!!");
}
}
Above code, I find all elements with the tagname of table and then see which one has the id ":pg".
Both these code snippets are essentially doing the same but using different ways(By.id or By.tagname). However, the first snippet of code which uses By.id always succeeds while the second snippet of code which uses By.tagname fails almost always. (It will work with additional waiting however)
Why is this difference between By.id and By.tagname?
Thanks,
Chris.
The :pg element is not present on the page initially.
Using By.Tag, selenium will not wait for the :pg element.
Because By.Id example is more specific, selenium will continue checking if the :pg element exists until the implicit wait (5 seconds) times out.
By.Tag is not specific at all. On findElements(By.tagName("table"), Selenium will return an array of all the tables that are present immediately after the page loads. As the :pg element is not present yet, it will not be in the array.
To answer your question, yes it is better to use By.Id because:
1. It is more specific.
2. Saves lines of code
3. Forces selenium to wait for the element to exist.
It is better to use By.Id according to your question.
By.tag is not used for specific data, it actually will search and return an array of all the tables with the specified tag name. On the other hand using id you can get the appropriate output for identifying/locating element.
Go for tag only if id, name or class is not specified and the best way can be By.cssSelector if no element is found.
Thanks
