Modifying the Code

Let's modify the sample code so that it pulls out the H3 tags rather than the H2 tags.

Duplicate the Code

Make a copy of scrape1-simple.js, calling it scrape1a-simple.js.

Modify the Code

Locate the section that selects the H2 tags:

    // Search for the elements we want
    selection = $('h2')

Change the code to select the H3 tags instead.

Run the Modified Code

Run the code from the Terminal session in Visual Studio Code:

node scrape1a-simple.js

You should see data.csv change as follows:

country
Tirana
Yerevan
Vienna
Baku
Minsk
Brussels
Sarajevo
Sofia
