title: Extracting data from a web page and inserting into html code of another webpage
body: <p>I have multiple webpages that only contain a single number in the HTML code, nothing else. These get updated from an IOT device I made. I also have a main data webpage, that is meant to display all of the data on one page. However, I cannot figure out how to extract the number the data webpages' in the HTML code of the main data webpage. </p>
  
  <p>The only workaround I have found is by using iframes, but this seems very clumsy, and not "pleasing for the eyes". Is there any way to do this using HTML, or maybe javascript? I am very new to web development. The only restriction is that I cannot change how the data is uploaded from the IoT device, so it has to be extracted from the individual data webpages that contain only numbers.</p>
  
  <p>Thanks in advance :) </p>
