I'm trying to crawl a webpage using node and cheerio. Everything is returning as I expect except for the hrefs.
I'm successfully returning values for 'headers' .find('h3').text() and 'descriptions' .find('a').text() but for 'links' .find('a').attr('href'); only the first is being returned. This confuses me as the text 'descriptions' are within the same anchor.
I've found that if I remove the .attr('href'); and just return .find('a') the link text (href) is displayed as expected. I can modify the returned value and make this work if need be but would prefer to do this correctly.
Script:
const cheerio = require("cheerio");
const axios = require("axios");
axios.get("http://localhost:8000/sample_page_2.html").then(urlResponse => {
const $ = cheerio.load(urlResponse.data);
$('div.tos-post-type').each((i, element) => {
const header = $(element)
.find('h3')
.text()
.trim();
console.log('------------------------------------------------------------------------------------');
console.log('HEADER: ' header);
const link = $(element)
.find('a')
.attr('href');
console.log('\nLINK(s): \n' link);
const description = $(element)
.find('a')
.text();
console.log('\nDESCRIPTION(s): \n' description '\n');
console.log('------------------------------------------------------------------------------------');
});
});
Here is a snippet of the page I'm trying to crawl:

Any ideas what I'm doing incorrectly?
Thanks!

Use map to get multiple attributes:
$(element).find('a').get().map(a => $(a).attr('href'))
