Customization
DZReadability provides various options for customizing the content extraction process. Here are some examples:
Option 1: Custom CSS Selector
You can specify a custom CSS selector to target specific elements for extraction:
“`swift

let readable = DZReadability(readabilityOptions: ReadabilityOptions(selector: “div.article-content”))
// …
“`
Option 2: Ignoring Specific Elements
If there are specific elements that you want to ignore during content extraction, you can exclude them using DZReadability’s `ignoredTags` property:
“`swift
// Create an instance of DZReadability with ignored tags
let readable = DZReadability(readabilityOptions: ReadabilityOptions(ignoredTags: [“aside”, “footer”]))
// …
“`
Option 3: Ignoring Classes
Similarly, you can ignore elements with specific class names:
“`swift
// Create an instance of DZReadability with ignored classes
let readable = DZReadability(readabilityOptions: ReadabilityOptions(ignoredClasses: [“advertisement”, “banner”]))
// …
“`
