英文:
data repetition in webscraping using xpath
问题
I understand your issue. To extract the specific information you want from the web page with a single occurrence, you can modify your XPath expression. Instead of using .map, you can use [1] to get the first occurrence of the element. Here's the modified code:
$x('//div[@class="cs"]/div/text()[1]').map(x => x.wholeText)
This code will give you an array with only one occurrence of each item:
['CS 35 (1.4)', 'CS 269 (7.3)', 'CS 137 (8.5)', 'CS 241 (7.5)', 'CS 226 (9.2)', ...]
By specifying [1], you are getting the first occurrence of the text within the specified div, which should solve your problem of repeated data.

Try changing your xpath expression to
$x('//div[@class="stats"]//div[@class="cs"]').map(x=>x.innerText)
Output should be:
[ "CS 35 (1.4)", "CS 269 (7.3)", "CS 137 (8.5)", "CS 226 (6.8)",
"CS 224 (7.7)", "CS 262 (8.7)", "CS 218 (8.8)", "CS 160 (5.6)",
"CS 252 (9.9)", "CS 239 (7)", … ]
