For parsing web scraped content in NodeJS using CSS selectors, we suggest using the Cheerio library emerges as a highly recommended tool. It affords developers the luxury of employing a jQuery-like syntax for traversing and manipulating the DOM of web pages, thus making the extraction of specific data points both efficient and straightforward. This capability is particularly valuable in scenarios where precise selection and rapid processing of web content are paramount. Augmenting your toolkit with a web scraping API can significantly bolster your scraping strategies. Such APIs are engineered to seamlessly navigate and extract data from websites, regardless of their complexity or the nature of the data protection measures in place. By combining Cheerio’s ease of use with the robustness of a professional scraping API, developers can achieve superior data extraction results, ensuring that their applications remain both powerful and scalable.
const cheerio = require('cheerio');
const $ = cheerio.load(`
<h1>Page title</h1>
<p>some paragraph</p>
<a href="http://bankstatementpdfconverter.com/">some link</a>
`);
$('h1').text();
"Page title"
$('a').attribute("href");
"http://bankstatementpdfconverter.com/"
Another well-regarded library is Osmosis, which supports HTML parsing through both CSS and XPath selectors:
const osmosis = require("osmosis");
const html = `
<a class="link" href="http://bankstatementpdfconverter.com/">link 1</a>
<a class="link" href="http://bankstatementpdfconverter.com/blog">link 2</a>
`
osmosis
.parse(HTML)
.find('a.link')
.log(console.log);
