ExtractCSSPat issue on search results

[hamedf62]

Dear Salim;
thank you so much for such great efforts and useful package!

i have an issue in crawling and data gathering in search result pages.

in ExtractCSSPat mentioned few CSS rules but some of the pages doesn't include the required data and CSS is not available on them.

below error would occured:
Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 1, 0
In addition: Warning messages:
1: In UseMethod("xml_remove") :
closing unused connection 7 (<-DESKTOP-K73RC4R:11502)
2: In UseMethod("xml_remove") :
closing unused connection 6 (<-DESKTOP-K73RC4R:11502)
3: In UseMethod("xml_remove") :
closing unused connection 5 (<-DESKTOP-K73RC4R:11502)
4: In UseMethod("xml_remove") :
closing unused connection 4 (<-DESKTOP-K73RC4R:11502)
5: In UseMethod("xml_remove") :
closing unused connection 3 (C:/Users/Hamed/Documents/tripadvisor.com-281027/extracted_data.csv)

****i though its possible to put a conditional statement to check if the CSS tag is not available then return null in data set.
