Question

Trying to work out how to search a website (eg https://www.fakewebsite.com/ ) for text between two stings (eg ABC text that changes from time to time XYZ ) and displays on my website. Think the following has something to do with it, but not sure how to scrape the data from the external site:

//Gets the part of the string inbetween the ABC and the XYZ
var part = str.substring(
    str.lastIndexOf("ABC") + 1, 
    str.lastIndexOf("XYZ")
);

Any ideas? Hope www.fakewebsite.com isn't a real site. Looking to do this with JavaScript as my site is a SharePoint site so scripting is a nightmare.

Answer 1

Hope that I understand your request. There are a few ways to go about realising this. In my opinion the easiest one is to try and match the text inside the requested website to regular expressions. If it helps you can reach here: https://regex101.com/

You can do something similar to what you did, like: body.match(/(text you want)/g), this should return an array with the matches or falsey.
