XPATH syntax for element in {} with Selenium for Python

I am currently trying to click each button on a webpage with Selenium in Python, the class and text is always the same for each button but each button has different ids. The ids, however, are within "data-paramaters" in {} and I can't figure out how to get the correct syntax for the xpath. Here is a snippet of the website for one of the buttons:

<span class="contains-icon-details gc-btn gc-btn--s" data-isneededpromise="false" data-parameters="{"partner":"gs", "realId": "8da1d6a9-44d1-4556-bc12-92699749a30a", "tnId": "102086182829", "type": "details"}">More Details</span>

It seems the realId and the tnId are unique, so I would need to find the buttons with either one of those.

This works:

driver.find_element_by_xpath("//span[@class='contains-icon-details gc-btn gc-btn--s']").click()

but of course only for the first button as the class is always the same.

I tried something like this:

driver.find_element_by_xpath("//*[contains(@tnId, '102086182829')]").click()

but I get

Unable to locate element: //*[contains(@tnId, '102086182829')]

so definitely not the correct syntax.

I tried to find a solution online, but with no luck so far. Can anybody point me into the right direction? Thanks in advance.

In case realId value or tnId value is unique your XPath can be

driver.find_element_by_xpath("//*[contains(@data-parameters, '8da1d6a9-44d1-4556-bc12-92699749a30a')]").click()

or

driver.find_element_by_xpath("//*[contains(@data-parameters, '102086182829)]").click()

you should filter by the "data-parameters" attribute.

Try

driver.find_element_by_xpath("//span[contains(@data-parameters, '102086182829')]").click()

This is a dirty implementation of what you need. It would be better to extract the data-parameters field, deserialize JSON and check for the needed field;

spans = driver.find_element_by_xpath("//span[@class='contains-icon-details gc-btn gc-btn--s']")
for span in spans:
    data_parameters = span.get_attribute("data-parameters")
    try:
        data_parameters = json.loads(data_parameters)
    except:
        continue

    if 'tnId' in data_parameters and data_parameters['tnId'] == "102086182829":
        span.click()
        break
