Answer 1

As you have a lot of inputs I suggest filtering for the type of the input, in this case for button. Then you can narrow down the buttons based on their value attribute.

In your case the xpath expression should look like this:

//form//input[@type='button' and contains(@value,'Pesquisar')]

You can use it to find an element by xpath from your test like:

driver.FindElement(By.XPath("//form//input[@type='button' and contains(@value,'Pesquisar')]"));

Answer 2

I think you are more aiming towards finding a correct locator for the desired button. You might consider using the below xpath:

//form//input[contains(text(), 'Pesquisar')]

in findElement by xpath as the locating strategy.
