Cheerio - Ensure accurate text retrieval for selectors that produce multiple results

https://i.stack.imgur.com/FfYeg.png

I am trying to extract specific market data from the given webpage. Specifically, I need to retrieve "Sábado, 14 de Abril de 2018" and "16:00". Here is how I did it using Kotlin and the jsoup library:

val date = select("div.col-sm-8 > span.text-2")[1] //Sábado, 14 de Abril de 2018
val time = select("div.col-sm-8 > span.text-2")[2] //16:00

The above query returns an array, and I can easily access the required information using the index. However, due to some constraints, I now have to accomplish the same task using JavaScript.

I attempted to achieve the same functionality with JavaScript and the Cheerio library, but encountered challenges as it does not seem to work in a similar manner compared to Kotlin's jsoup. Both libraries are based on JQuery-like search modes:

// JavaScript code snippet
// Full code available at provided URL
let date = $("div.col-sm-8 > span.text-2")[1];
let time = $("div.col-sm-8 > span.text-2")[2];

console.log(date);
console.log(time);

When I executed the JavaScript code, I received unexpected results showing that date.text() was not functioning properly. By printing only the query result, I observed nested objects being returned instead of plain text values.

As someone relatively new to JavaScript, I need assistance on how to properly extract the desired information from the retrieved HTML content. Any guidance or alternative approaches would be highly appreciated.

Answer №1

If you want to retrieve a specific Cheerio element by index, you can utilize the eq() method, which works similarly to how it does in jQuery.

let date = $("div.col-sm-8 > span.text-2").eq(1);
let time = $("div.col-sm-8 > span.text-2").eq(2);

The eq() function allows you to target a particular element within the selection based on its index position.

Answer №2

My goal was achieved through the use of the slice method:

let date = $("div.col-sm-8").find("span").slice(1);                    
let time = $("div.col-sm-8").find("span").slice(2);

console.log(date.text());
console.log(time.text());
