如何获得带有cheerio的itemprop元素值？

Question

我第一次尝试在cheerio库中从paginas amarillas进行一些Web抓取操作，例如公司名称，地址等。该地址位于没有类的范围内，只有[C0 ]，我尝试了不同的方法，因为到达该选择器是一个很长的字符串，我一直获取数据，直到itemprop之前的那个，但是我不知道如何瞄准itemprop选择器，我遇到的麻烦是pathAddreses常量，它将在控制台日志上返回一个空数组，如果我删除字符串的最后一个元素（itemprop="streetAddres"），它将带给我数据，但不完全是我想要的那个]

这里是代码：

itemprop='streetAddres'

如果只想使用

const cheerio = require("cheerio");
const request = require("request-promise");
//const of the classes of the paginas amarillas elements we are aiming to
const pathProfesionals1 =
  ".container .row .first-content-listado .col-lg-7.col-md-8.col-xs-12 .bloque-central .central .listado-item.item-ip .box .cabecera .row .col-xs-11.comercial-nombre a h2 span";
const pathProfesionals2 =
  ".container .row .first-content-listado .col-lg-7.col-md-8.col-xs-12 .bloque-central .central .listado-item.item-ig .box .cabecera .row .col-xs-11.comercial-nombre a h2 span";
const pathTelephones1 =
  ".container .row .first-content-listado .col-lg-7.col-md-8.col-xs-12 .bloque-central .central .listado-item.item-ip .box .pie-pastilla .row .col-xs-4 a.llama-desplegable.btn.btn-amarillo.btn-block.phone.hidden.d-none span";
const pathTelephones2 =
  ".container .row .first-content-listado .col-lg-7.col-md-8.col-xs-12 .bloque-central .central .listado-item.item-ig .box .pie-pastilla .row .col-xs-4 a.llama-desplegable.btn.btn-amarillo.btn-block.phone.hidden.d-none span";
const pathAddress1 = `.container .row .first-content-listado .col-lg-7.col-md-8.col-xs-12 .bloque-central .central .listado-item.item-ig .box .row a .location span *[itemprop = 'streetAddress']`;

const pathAddress2 = "";

init = async () => {
    const arrCompanyName = [];
    const arrTelephones = [];
    const arrAddresses = [];

    const { category, city } = this.state;

    const $ = await request({
      uri: `https://www.paginasamarillas.es/search/${category}/all-ma/${city}/all-is/malaga/all-ba/all-pu/all-nc/1?what=carpintero&where=malaga&ub=false&qc=true`,
      transform: body => cheerio.load(body) //una vez hago la peticion lo paso a cheerio para que lo analice
    });

    const profesionals1 = $(pathProfesionals1).each((i, el) =>
      arrCompanyName.push($(el).text())
    );

    const telephones1 = $(pathTelephones1).each((i, el) =>
      arrTelephones.push($(el).text())
    );

    const profesionals2 = $(pathProfesionals2).each((i, el) =>
      arrCompanyName.push($(el).text())
    );

    const telephones2 = $(pathTelephones2).each((i, el) =>
      arrTelephones.push($(el).text())
    );

    const addresses1 = $(pathAddress1).each((i, el) =>
      arrAddresses.push($(el).text())
    );

    console.log(arrAddresses);
}

属性选择span标签，则需要从地址选择器中删除itemprop='streetAddress'。目前，Cheerio尝试使用* inside and not with
