基于R的Power仪表板的数据抓取
基于R的Power仪表板的数据抓取
提问于 2022-09-26 13:26:33
我试图使用R中的Selenium在这个Power仪表板上创建一个数据集的.csv，仪表板是这里
我有问题，把数据抓取到适当的列，我需要滚动查看更多的数据，以便刮除整个列表。
我目前正在尝试的代码可以从表中提取，但它会创建一个无组织且不完整的数据集。我很难找到一个解决方案，如何干净地刮掉这个仪表板，并在我的R代码中添加一个滚动组件。我使用的代码是从这个职位引用的。
以下是我当前的R代码：
library(dplyr)
library(purrr)
library(readr)
library(wdman)
library(RSelenium)
library(xml2)
library(selectr)
selServ <- selenium(
port = 4444L,
version = 'latest',
chromever = '105.0.5195.19')
remDr <- remoteDriver(
remoteServerAddr = 'localhost',
port = 4444L,
browserName = 'chrome'
)
remDr$open()
report_url <- "https://app.powerbi.com/view?r=eyJrIjoiNmY4MTQyN2YtNTMyOC00NWMyLTk0ZWUtNDA1ZTllNDZlMTE0IiwidCI6IjZiY2NiNTZkLWI1YTQtNDkzOC05MGRhLTNhNDE4ZjA0MDJjYyIsImMiOjF9&pageName=ReportSection787ec227054b3e646910"
remDr$navigate(report_url)
zipcode_data_table <- read_html(remDr$getPageSource()[[1]]) %>%
querySelector("div.tableEx")
col_headers <- zipcode_data_table %>%
querySelectorAll("div.columnHeaders div.pivotTableCellWrap") %>%
map_chr(xml_text)
zipcode_data <- zipcode_data_table %>%
querySelectorAll("div.bodyCells div.pivotTableCellWrap") %>%
map(xml_parent) %>%
unique() %>%
map(~ .x %>% querySelectorAll("div.pivotTableCellWrap") %>% map_chr(xml_text)) %>%
bind_cols()
df_final <- tibble(final = col_headers, zipcode_data) %>%
type_convert(trim_ws = T, na = c(""))回答 1

我已经能够使用以下代码提取表的行：
library(RSelenium)
library(rvest)
library(stringr)
url <- "https://app.powerbi.com/view?r=eyJrIjoiNmY4MTQyN2YtNTMyOC00NWMyLTk0ZWUtNDA1ZTllNDZlMTE0IiwidCI6IjZiY2NiNTZkLWI1YTQtNDkzOC05MGRhLTNhNDE4ZjA0MDJjYyIsImMiOjF9&pageName=ReportSection787ec227054b3e646910"
shell('docker run -d -p 4445:4444 selenium/standalone-firefox')
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
remDr$open()
remDr$navigate(url)
Sys.sleep(5)
remDr$mouseMoveToLocation(x = 1035, y = 650)
list_Table <- list()
counter <- 1
for(l in 0 : 30)
{
if(l %% 10 == 0)
{
web_Obj_Table <- remDr$findElement("xpath", '/html/body/div[1]/report-embed/div/div/div[1]/div/div/div/exploration-container/div/docking-container/div/div/div/div/exploration-host/div/div/exploration/div/explore-canvas/div/div[2]/div/div[2]')
vector_Info <- strsplit(web_Obj_Table$getElementText()[[1]], "\n")[[1]]
vector_Info <- vector_Info[-(1 : 22)]
nb_Item <- length(vector_Info)
list_Row_Table <- list()
counter_Temp <- 1
for(i in 1 : nb_Item)
{
list_Row_Table[[counter_Temp]] <- ""
if(stringr::str_detect(vector_Info[i], "\\d{5,9}") == TRUE)
{
list_Row_Table[[counter_Temp]] <- paste0(list_Row_Table[[counter_Temp]], ";;;", vector_Info[i])
counter_Temp <- counter_Temp + 1
}else
{
list_Row_Table[[counter_Temp - 1]] <- paste0(list_Row_Table[[counter_Temp - 1]], ";;;", vector_Info[i])
}
}
list_Row_Table <- lapply(X = list_Row_Table, FUN = function(x) strsplit(x, ";;;")[[1]])
list_Table[[counter]] <- do.call("rbind", list_Row_Table)
counter <- counter + 1
}
print(l)
remDr$doubleclick()
