Question

我正在尝试获取有关撰写特定评论的评论者的详细信息。

问题是当你移动到某个部分时，评论者的信息弹出。我可以用硒做到这一点。

url<-"https://www.tripadvisor.com/Hotel_Review-g644300-d668891-Reviews-Hotel_Creina-Kranj_Upper_Carniola_Region.html#REVIEWS"

driver<- rsDriver()
remDr <- driver[["client"]]


remDr$open()

remDr$navigate(url)

details <- remDr$findElement(using = "xpath", paste("(//div[@class='username mo'])"))

remDr$mouseMoveToLocation(webElement=details)

我怎样才能得到一个memberid？ See image.

h<-read_html(url)

id<-html_attr(html_node(h,".expand_inline"),"class")

id 是 expand_inline scrname mbrName_9520BF5DXXXXX

id2<-gsub("expand_inline scrname mbrName_","",id)

id2 是 9520BF5DXXXXX

indurl<-paste0("https://www.tripadvisor.co.kr/MemberProfile-a_uid.",id2)

indinfo<-read_html(indurl)

名称<-html_text(html_node(indinfo,".nameText"));名称
