I have an XPath query that looks like this, with both single and double quotes. How do I escape the apostrophe properly so that the query works?

I tried:

rating<- getNodeSet(doc1,"//*[(@id = "taplc_location_reviews_list_apd_0")]//*[contains(concat( " ", @class, " " ), concat( " ", "ui_bubble_rating", " " ))]"

How can I use this Xpath so that I'm able to scrape rating from Tripadvisor?

It's giving an error:

Error: unexpected symbol in "rating<- getNodeSet(doc1,"//*[(@id = "taplc_location_reviews_list_apd_0"

Try replacing the double quotes inside the xpath to single quotes (but leave the double quotes around the xpath), like so:

rating<- getNodeSet(doc1,"//[(@id = 'taplc_location_reviews_list_apd_0')]//[contains(concat( ' ', @class, ' ' ), concat( ' ', 'ui_bubble_rating', ' ' ))]"
