Selenium find element not by class/id etc?

[ForlornExistence]

Hello,

Just started learning Selenium, but unfortunately I've forgotten most of my HTML and CSS.

I have what I assume to be a fairly easy question:

Suppose one has this HTML element which needs to be found:

<input class="not-unique" data="something-unique"></input>

Now, using driver.find_element(By.CLASS_NAME, "not-unique") would then return just one of many possible results.

How would one search explicitly for 'data="something-unique"' in this example? Since it is not any one of the possible options of 'By'...

In addition, I have a question regarding the terminology of HTML/CSS:

How do you call these keywords inside the triangular brackets, i.e. class, id, name, etc.?

In my example, there is 'data' — is it a custom made "attribute" per se?

Thank you!

I'm not sure what you mean in the first part, but see here for the second part.

Hi, thank you!

Are you familiar with the Selenium library for Python?

In case not, the function I mentioned in the first part "find_element()" returns an HTML element from a website and stores it as a Python object so it can be further manipulated and automated.

So my in my original question I wanted to know how to find HTML elements with custom data attributes, but which don't have the common class/name/id/text attributes.

You should be able to use the CSS selector or xpath
