我有以下链接
url = "https://timesofindia.indiatimes.com/topic/Adani"
在上面的网址中，我想提取标题，在3个不同的列中提取标题和日期。
我只能提取一个新闻标题和段落以下代码
results_headline <- url2 %>%
read_html() %>%
html_nodes(xpath='//*@id="c_topic_list1_1"]/div[1]/ul/li[4]/div/a/span[1]')
results_para <- url2 %>%
read_html() %>%
html_nodes(xpath='//*[@id="c_topic_list1_1"]/div[1]/ul/li[4]/div/a/p')
我想提取该页面上的所有标题，段落和日期。 我怎么能在R？
中做到这一点答案 0 :(得分：1)
您可以再次使用css选择器来提取内容。
url2 = "https://timesofindia.indiatimes.com/topic/Adani"
titles <- url2 %>% read_html() %>% html_nodes("div > a > span.title") %>% html_text()
dates <- url2 %>% read_html() %>% html_nodes("div > a > span.meta") %>% html_text()
desc <- url2 %>% read_html() %>% html_nodes("div > a > p") %>% html_text()
data.frame(titles,dates,desc)
输出：
> data.frame(titles,dates,desc)
