The code is using a CSS selector and the Cheerio library to parse HTML and select specific elements, specifically targeting an element named "importer" that is a direct child of an element with a type attribute containing "StaticMemberExpression".

Additionally, it loads an HTML document or string into a Cheerio object using the cheerio.load() function.

Cell 5



//""`*[type*='StaticMemberExpression'] > *[name=="importer"]`;
//var $ = cheerio.load(page);

What the code could have been:

// Import required libraries
const cheerio = require('cheerio');

/**
 * Retrieves a static member expression from a given HTML page.
 * The expression is identified by the name "importer".
 * @param {string} page - The HTML page to parse.
 * @returns {Cheerio} The parsed HTML page.
 */
function getImporterExpression(page) {
  // Note: Cheerio.load() is a synchronous method. For real-time information, use async/await or promises.
  // TODO: Consider using a more efficient parsing library, like DOMParser.
  const $ = cheerio.load(page);
  
  // Use Cheerio to find the static member expression with name "importer"
  const importerExpression = $('*[type="StaticMemberExpression"]')
   .filter((index, element) => $(element).attr('name') === 'importer')
   .first();
  
  // Return the parsed HTML page
  return $;
}

// Example usage:
const page = '<HTML>...</HTML>'; // Replace with actual HTML content
const result = getImporterExpression(page);
console.log(result.html());
