scrapedCore($, opts)

Scrapes the data in the provided element.

For the format of the selector, please refer to the Selectors section of the Cheerio library

Params

• Cheerio|String $: The input element or the HTML as a string.

• Object opts: An object containing the scraping information. If you want to scrape a list, you have to use the listItem selector:

  • listItem (String): The list item selector.
  • data (Object): The fields to include in the list objects:
    • <fieldName> (Object|String): The selector or an object containing:
      • selector (String): The selector.
      • convert (Function): An optional function to change the value.
      • how (Function|String): A function or function name to access the value.
      • attr (String): If provided, the value will be taken based on the attribute name.
      • trim (Boolean): If false, the value will not be trimmed (default: true).
      • closest (String): If provided, returns the first ancestor of the given element.
      • eq (Number): If provided, it will select the nth element.
      • texteq (Number): If provided, it will select the nth direct text child. Deep text child selection is not possible yet. Overwrites the how key.
      • listItem (Object): An object, keeping the recursive schema of the listItem object. This can be used to create nested lists.

  Example:

  {
     articles: {
         listItem: ".article"
       , data: {
             createdAt: {
                 selector: ".date"
               , convert: x => new Date(x)
             }
           , title: "a.article-title"
           , tags: {
                 listItem: ".tags > span"
             }
           , content: {
                 selector: ".article-content"
               , how: "html"
             }
           , traverseOtherNode: {
                 selector: ".upperNode"
               , closest: "div"
               , convert: x => x.length
             }
         }
     }
  }
  

  If you want to collect specific data from the page, just use the same schema used for the data field.

  Example:

  {
       title: ".header h1"
     , desc: ".header h2"
     , avatar: {
           selector: ".header img"
         , attr: "src"
       }
  }
  

Return

• Object The scraped data.
