当缺少&lt；tr&gt；标记时，使用rvest R-擦除HTML表格

我正在尝试使用rvest从网站上抓取一个HTML表。唯一的问题是，我要清理的表没有<tr>标记，第一行除外。如下所示：

<tr> 
  <td>6/21/2015 9:38 PM</td>
  <td>5311 Lake Park</td>
  <td>UCPD</td>
  <td>African American</td>
  <td>Male</td>
  <td>Subject was causing a disturbance in the area.</td>
  <td>Name checked; no further action</td>
  <td>No</td>
</tr>

  <td>6/21/2015 10:37 PM</td>
  <td>5200 S Blackstone</td>
  <td>UCPD</td>
  <td>African American</td>
  <td>Male</td>
  <td>Subject was observed fighting in the McDonald's parking lot</td>
  <td>Warned; released</td>
  <td>No</td>
</tr>

等等。因此，使用以下代码，我只能将第一行放入我的数据框中：

library(rvest)
mydata <- html_session("https://incidentreports.uchicago.edu/incidentReportArchive.php?startDate=06/01/2015&endDate=06/21/2015") %>%
    html_node("table") %>%
    html_table(header = TRUE, fill=TRUE)

如何更改它以使html_table理解这些行就是行，即使它们没有开始<tr>标记？或者，有没有更好的办法来解决这个问题？

解决方案

library(rvest)

url_parse<- read_html("https://incidentreports.uchicago.edu/incidentReportArchive.php?startDate=06/01/2015&endDate=06/21/2015") 

col_name<- url_parse %>%
  html_nodes("th") %>%
  html_text()

mydata <- url_parse %>%
  html_nodes("td") %>%
  html_text()

finaldata <- data.frame(matrix(mydata, ncol=7, byrow=TRUE))

names(finaldata) <- col_name

finaldata
