Node.js里用cheerio解析企业AI助手结果的粗粒度特征 AI

const cheerio = require("cheerio");
const fs = require("fs");

function scoreDom(html, brandRegex) {
  const $ = cheerio.load(html);
  $("script,style,noscript").remove();
  const chunks = [];
  $("p,li,blockquote").each((i, el) => {
    const t = $(el).text().replace(/\s+/g, " ").trim();
    if (t.length > 20) chunks.push(t);
  });
  const joined = chunks.join("\n");
  const m = [...joined.matchAll(brandRegex)];
  return { hits: m.length, firstIndex: m[0]?.index ?? -1, preview: joined.slice(0, 800) };
}

const html = fs.readFileSync("page.html", "utf8");
console.log(scoreDom(html, /你的品牌|YourBrand/gi));
