An unhandled exception of type OpenQA.Selenium.InvalidSelectorException occurred in WebDriver.dll
Additional information: invalid selector: Unable to locate an element with the xpath expression //*[#id='hdtb-msb']/div[1]/div[4]/a) because of the following error:
SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//*[#id='hdtb-msb']/div[1]/div[4]/a)' is not a valid XPath expression.
I have tried finding the element through Class as well -- didn't seem to be working. Then remembered that it could be a time issue. After reading several articles/posts, I am not sure what else to try.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
namespace Webdemo2
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver = new ChromeDriver();
driver.Url = "http://gooogle.com";
var searchbox = driver.FindElement(By.Id("lst-ib"));
searchbox.SendKeys("Pluralsight");
//adding timeout
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(7));
var images = driver.FindElement(By.XPath("//*[#id='hdtb-msb']/div[1]/div[4]/a)"));
images.Click();
}
}
}
At the end of your xpath expression:
/a)
I think you need to take that closing parenthesis out of the expression.

Hello everyone I need some help. There is URL: http://lisans.epdk.org.tr/epvys-web/faces/pages/lisans/petrolBayilik/petrolBayilikOzetSorgula.xhtml. As you can see in screenshot I need to click checkbox Captcha.
https://i.stack.imgur.com/xjXaA.png
Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
namespace AkaryakitSelenium
{
class Program
{
private static string AkaryakitLink = "http://lisans.epdk.org.tr/epvys-web/faces/pages/lisans/petrolBayilik/petrolBayilikOzetSorgula.xhtml";
static void Main(string[] args)
{
IWebDriver driver = new ChromeDriver();
IJavaScriptExecutor js = driver as IJavaScriptExecutor;
driver.Navigate().GoToUrl(AkaryakitLink);
var kategoriCol = driver.FindElements(By.CssSelector(".ui-selectonemenu-trigger.ui-state-default.ui-corner-right"));
var x = kategoriCol[3];
x.Click();
var deneme = driver.FindElement(By.Id("petrolBayilikOzetSorguKriterleriForm:j_idt52_1"));
deneme.Click();
var check = driver.FindElement(By.Id("recaptcha-anchor"));
check.Click();
}
}
}
And lastly this error that I am facing:
"OpenQA.Selenium.NoSuchElementException: 'no such element: Unable to
locate element: {"method":"css
selector","selector":"#recaptcha-anchor"}"
Thank you for your help.
The element you are looking for is inside an iframe :
//iframe[#title='reCAPTCHA']
first you need to switch to iframe like this :
new WebDriverWait(driver, TimeSpan.FromSeconds(3)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.XPath("//iframe[#title='reCAPTCHA']")));
then you can perform a click on it :
var check = driver.FindElement(By.Id("recaptcha-anchor"));
check.Click();
PS : captchas are not meant to be automated. since Captcha stands for CAPTCHA stands for the Completely Automated Public Turing test to tell Computers and Humans Apart.
You can not bypass captcha with Selenium.
It is designed to avoid automated access to web pages as described here and in many other places.
I am trying to make a bot that goes through drop-downs and makes selections but it's having trouble finding the element. The code is below.
using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.Extensions;
using OpenQA.Selenium.Support.UI;
namespace selenium_test
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver;
driver = new ChromeDriver("C:\\");
Console.WriteLine("ChromeDriver Initialized");
driver.Url = "https://odyssey.gwinnettcourts.com/Portal/Home/Dashboard/26";
IWebElement typeElement = driver.FindElement(By.XPath(".//option[#id='cboHSSearchBy']"));
var typeSelect = new SelectElement(typeElement);
typeSelect.SelectByValue("JudicialOfficer");
typeElement.Click();
}
}
}
what exactly is the error? I can only assume that it is taking time to find element.
add wait time maybe? also, why using xpath when you have id of controls? id is quicker!
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementExists((By.Id("cboHSSearchBy"))));
Trying to remotly connect to another PC's WMI but when creating the CimSession I get the following error
System.InvalidProgramException:'Common Launguage Runtime detexted an invalid program'
The code I am running is as follows
using System;
using System.Text;
using System.Threading;
using Microsoft.Management.Infrastructure;
using Microsoft.Management.Infrastructure.Options;
using System.Security;
namespace SMAPIQuery
{
class Program
{
static void Main()
{
string computer = "ComputerB";
DComSessionOptions DComOptions = new DComSessionOptions();
DComOptions.Impersonation = ImpersonationType.Impersonate;
CimSession Session = CimSession.Create(computer, DComOptions);
}
}
}
Unsure as to what throws this error or how to get around it
The issue was I was using .Net Core and not .Net Framework
I'm running a basic c# test below. My test is essentially going to go onto www.asos.com then search for a specific item. When the search results are loaded I want to click on the first item that's returned. I tried to use CSS selector to click on the first imagine but I get an exception. Invalid selector.

{
IWebDriver webDriver = new ChromeDriver();
webDriver.Navigate().GoToUrl("http://www.asos.com/men/");
webDriver.Manage().Window.Maximize();
webDriver.FindElement(By.XPath(".//input[#data-testid='search-input']")).SendKeys("Polo Ralph Lauren Oxford Shirt In Regular Fit Blue");
webDriver.FindElement(By.XPath(".//button[#data-testid='search-button-inline']")).Click();
//*[#id="product-6153807"]/a/div[1]/img Xpath of the image to be clicked on
webDriver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
webDriver.FindElement(By.CssSelector("6153807")).Click();
}
}
}
use the following css selector.
article img
in code,
webDriver.FindElement(By.CssSelector("article img")).Click();
I've just installed Solr/Lucene on a Windows machine simply to test its capability. I've indexed a couple hundred files and I'm able to successfully query the indexed content through the web interface. Given that the web interface isn't too user friendly I thought I'd try to create a simple application to do a full text search over the indexed content. So far I have:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using Lucene.Net;
namespace solrTest
{
class Program
{
static void Main(string[] args)
{
string indexFileLocation = #"C:\solr-5.3.1\server\solr\test\data\index";
Lucene.Net.Store.Directory dir = Lucene.Net.Store.FSDirectory.Open(indexFileLocation);
Lucene.Net.Search.IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher(dir);
Lucene.Net.Index.Term searchTerm = new Lucene.Net.Index.Term("ID", "1");
Lucene.Net.Search.Query query = new Lucene.Net.Search.TermQuery(searchTerm);
Lucene.Net.Search.TopDocs results = searcher.Search(query, null, 10);
foreach(Lucene.Net.Search.ScoreDoc test in results.ScoreDocs)
{
Console.WriteLine(test.ToString());
Console.ReadLine();
}
}
}
}
When running the code I receive an error stating:
An unhandled exception of type 'System.IO.IOException' occurred in Lucene.Net.dll
Additional information: read past EOF
I know I'm missing something obvious. Your help would be greatly appreciated.
Edit: I downloaded Luke.Net and received the same error.
