Locating label element using class

I'm trying to locate the label element and fill it with some value but I'm not able to get it. I'm using Java, testNG and Selenium to write the below code.
The code that I used is below
driver.findElement(By.className("ng-pristine ng-empty ng-invalid ng-invalid-required ng-valid-maxlength ng-touched")).sendKeys("12345");
OR
driver.findElement(By.className("item-input-wrapper scan-input-label")).sendKeys("12345");
This is the details of element that I received when I inspect the element.

Actually selenium doesn't support to locate an element using By.className() with compound class name. You should try using By.cssSelector() instead to locate <input> element as below :-
driver.findElement(By.cssSelector("input[placeholder = 'Scan Container Label']")).sendKeys("12345");
Or more specific :-
driver.findElement(By.cssSelector("input[placeholder = 'Scan Container Label'][ng-model *= 'ctrl.currentValue']")).sendKeys("12345");
Edited :- If you want to locate <label> element using their class name try as below :-
driver.findElement(By.cssSelector("label.item-input-wrapper.scan-input-label"));
Or you can locate it also using By.className() with anyone if the single class name as :-
driver.findElement(By.className("item-input-wrapper"));

Actually selenium doesn't support to locate an element using By.className()
You can try syntax of css with classname, css=tagname.classname
i.e.
driver.findElement(By.cssSelector(input.item-input-wrapper)).sendKeys("12345");

Finding element with dynamic xpath not working

I have this in the HTML:
<textarea name="comment" class="form-control" rows="3" id="textarea_1160688690910416779_2159935466"></textarea>
I want to interact with id=textarea_, but the numbers are constantly changing after the "_". To solve this, I used this code:
driver.findElement(By.xpath("[starts-with(#id, 'textarea')")).sendKeys(comment);
However I am getting the error:
org.openqa.selenium.NoSuchElementException: Unable to locate element:

Use
driver.findElement(By.xpath("//textarea[starts-with(#id,'textarea_')]")).sendKeys(comment);

The reason you're getting this error is that you need to add '//' before your current XPath.
You could either use starts-with, this way:
("//textarea[starts-with(#id, 'textarea_')]")
You could also give 'contains' a try:
("//textarea[contains(#id, 'textarea_')]")
In both ways, you could use //*[... instead of textarea, for more cases

Your Xpath is not a valid Xpath.
It should contain a path and tag name
and it should be balanced (your [ is not closed)
So, if your tag is, textarea, and if it is at top: use /textarea
if not at top, use //textarea
This gives: "//textarea[starts-with(#id, 'textarea')]"

findElement by class where content equals text

I'm trying to locate and click an element on my page but can't use the by.id method as the id's are generated and change per session. For most elements I can get around this by using xpath but there is a dropdown menu where this does not work. I can click the element containing the dropdown and it shows me the options. If I locate the element I need and copy it's xpath the test case won't function stating it can't find the xpath. Now next to the id the Element I'm trying to click also has a class. Problem is that this class is not unique, all menu items in the dropdown have the same class with a different text. What I would like to do is something like:
driver.findeElement(By.class("x-menu-item-text").equals("Unique text 1here").click()
The class "x-menu-item-text" is not unique but the text in this particular class is. I can't use the ID as this is automatically generated. The full code for the item or element I want to click is:
<a id="ext-comp-1035" class="x-menu-item" hidefocus="true" unselectable="on" href="#"><span id="ext-gen250" class="x-menu-item-text">Unique text 1 here</span></a>
<a id="ext-comp-1035" class="x-menu-item" hidefocus="true" unselectable="on" href="#"><span id="ext-gen250" class="x-menu-item-text">Unique text 2 here</span></a>
I'm using Selenium Webdriver with Eclipse (Java).
Allthough the answer provided seems to work on most pages and locations, there is a situation however where I can't get it to work. Can anyone advise?
There is a page with buttons and I want to click one of these buttons. If I use the following statement:
driver.findElement(By.xpath("//*[#class=' x-btn-text' and text()='Add']")).click();
I get an error message
org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with
If I look at the source I see:
<button class=" x-btn-text" id="ext-gen539" type="button">Add</button>
So the element is present and visible.
I've tried adding a wait.until statement before the click statement but this does not work either:
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[#class=' x-btn-text' and text()='Toevoegen']")));
driver.findElement(By.xpath("//*[#class=' x-btn-text' and text()='Toevoegen']")).click();
Extra information: could this problem be because I'm looking for an element that is located in a popup?

You can use xpath locator

By.xpath("//span[#class='x-menu-item-text' and text()='Unique text 1here']")

How to access dynamic text within HTML icon tag with selenium WebDriver?

<span class="class name">16</span>
The "16" is dynamic and I don't know how to access it using Selenium Webdriver in java. I've tried By.xpath() and it didn't work but I feel like cssSelector would be more robust in this situation. could someone tell me how to access the 16. I'm writing a method to check the expected value to the given value. The 16 is part of an icon. I don't think that will make a difference because the cssSelector should still do the job.

You would do something like:
WebDriver driver = new FirefoxDriver();
String content = driver.find_element_by_class_name("class name").getText();
If there are multiple elements with the same class name you can use find_elements_by_class_name and iterate through them.

You could add a "data-" tag to the span element: example <span class="class name" data-hook="some.element.number">16</span>
Then your locator would look like this --> driver.findElement(By.cssSelector("[data-hook='some.element.number']");

Selenium WebDriver Finding Element by Partial Class Name

In the frame I'm working with, I have the following element:
<div class="x-grid3-cell-inner x-grid3-col-expRepCol"> New session from client IP 192.168.5.3 (ST=/CC=/C=) at VIP 192.168.5.2 Listener /Common/Tomcat (Reputation=Unknown)</div>
As well as many other similar elements. I am trying to locate this element by partial name text and click it with the following code:
String expectedText = "New session from client IP";
driver.findElement(By.className("div[class*='"+expectedText+"']")).click();
And I have also tried with cssSelector:
String expectedText = "New session from client IP";
driver.findElement(By.cssSelector("div[class*='"+expectedText+"']")).click();
But WebDriver keeps throwing an exception stating it's unable to locate that element. Any suggestions as to what could be the problem?

<div class="dd algo algo-sr Sr" data-937="5d1abd07c5a33">
<div class="dd algo algo-sr fst Sr" data-0ab="5d1abd837d907">
Above 2 are the HTML elements in yahoo search results. So if we wanna get these elements using partial class name with selenium python, here is the solution.
driver.find_element_by_css_selector("div[class^='dd algo algo-sr']")
In the same way we can get any elements with partial match on any attribute values like class name, id etc.
find elements with css selector partial match on attribute values

By.className is looking for a class with the name entered.
By.cssSelector is looking for a match for the selector you entered.
What you're attempting is to match the text of the div against class, which won't work.
You can try something like this:
driver.findElement(By.xpath("//div[contains(text(),'"+expectedText+"')]")).click();

I believe this will work:
driver.findElement(By.className("x-grid3-cell-inner x-grid3-col-expRepCol").click();
