将雅虎金融股票价格抓取到谷歌表格

Question

So I can get the xpath working for "mainstream" stocks like CVNA with this line:

=REGEXEXTRACT(INDEX(IMPORTXML("https://finance.yahoo.com/quote/CVNA?p=CVNA";"//*[@id='quote-header-info']");;3); "\d+.\d+|\d+")+0

But when trying to point to a specific exchange like Oslo exchange I get an error. Would like to scrape stock prices from NEL.OL

Any suggestions?

As the page is built in javascript on the client side and not on the server side, you will not be able to retrieve the data by the importxml / importhtml functions. However, the page contains a json which you can retrieve and analyze to retrieve the information you need.

  var source = UrlFetchApp.fetch(url).getContentText()
  var jsonString = source.match(/(?<=root.App.main = ).*(?=}}}})/g) + '}}}}'
  var data = JSON.parse(jsonString)

for instance, for marketprice, you can retrieve the informations by

function marketPrice(code) {
  var url='https://finance.yahoo.com/quote/'+code
  var source = UrlFetchApp.fetch(url).getContentText()
  var jsonString = source.match(/(?<=root.App.main = ).*(?=}}}})/g) + '}}}}'
  var data = JSON.parse(jsonString)
  var regularMarketPrice = data.context.dispatcher.stores.StreamDataStore.quoteData[code].regularMarketPrice.raw
  return regularMarketPrice
}
