Rip text from a website into a string indicator on a Front Panel


This example demonstrates extracting text from a webpage.



Starting with a WebBrowser ActiveX control, invoke and property nodes are used to navigate to a URL and extract the text from the webpage.



  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Type the URL of a webpage into the URL text control, such as " http://www.google.com ".
  2. Run the VI.

This is a great VI!  I've been trying to migrate some online spreadsheets into LabVIEW for analysis, and until now I've had to copy every page into Excel or notepad first!  This is going to save me the longest, most manual step of the whole process.  Thanks!!!

Looks simmilar to the example here: http://zone.ni.com/devzone/cda/epd/p/id/2743

That works great and I have been using for a while now to test POE devices that have a status webpage.

But I don't have LV 8.6 so I can't really compare them...

Unfortunately, most readers of this Forum, including some real Experts, have not mastered the skill of being able to read the code that Posters fail to post. If we cannot see "what you did wrong", we are unable to tell you how to fix it. (Bob Schor 28 August 2018)

Is there any way to interact with the resulting page?  I want to extract text from a bank account.  Need to be able to login to account first, go to account page, then rip text.

I use datasocket read to extract the html source from URL addresses. Far simpler:
