XPath: Find element that contains text X and not Y

Question

I'm attempting to find a web element using XPath in Selenium for Python. The web element should contain the text "Chocolate" but not include "Dark" .

I've tried this syntax but not gotten it to work (be mindful of parantheses):

choco = driver.find_element_by_xpath("//*[text()[contains(., 'Chocolate')] and not[[contains(., 'Dark')]]]")

Here is the same code using line breaks and concatenation for readability:

choco = driver.find_element_by_xpath((
                                    "//*[text()[contains(., 'Chocolate')]" + 
                                    "and not[[contains(., 'Dark')]]]"
                                    ))

Answer 1

请尝试遵循XPath并让我知道是否发生任何错误：

//*[contains(text(), "Chocolate")][not(contains(text(), "Dark"))]

Answer 2

Here is the syntax with using just one set of square brackets.

For elements containing the word 'Chocolate' but not 'Dark', use:

//*[contains(text(), 'Chocolate') and not(contains(text(), 'Dark'))]

For just the text of the elements, use:

//text()[contains(., 'Chocolate') and not(contains(., 'Dark'))]

Given the following XML:

<doc>
  <e>Dark Chocolate</e>
  <e>Chocolate</e>
</doc>

The first expression results in:

> xpath -e "//*[contains(text(), 'Chocolate') and not(contains(text(), 'Dark'))]" test.xml 
<e>Chocolate</e>

The second expression results in:

> xpath -e "//text()[contains(., 'Chocolate') and not(contains(., 'Dark'))]" test.xml 
Chocolate
