What does contains(., 'some text') refers to within xpath used in Selenium

Question

我是硒编码的新手，我看到几个 xpath 包含 (.,'followed by something') ., 指的是什么？

Answer 1

The . character within the xpath is the short form of text()

As an example if an WebElement is represented within the DOM Tree as:

<span>Use this payment method</span>

Effective Locator Strategies will be:

• xpath 1 :

   //span[text()='Use this payment method']

• xpath 2 :

   //span[contains(., 'Use this payment method')]
