Yes, SwiftSoup is a Swift library that can parse HTML from a string. SwiftSoup provides a set of powerful APIs inspired by the popular Java library Jsoup. It allows Swift developers to parse, traverse, and manipulate HTML documents in a type-safe and convenient manner.
To use SwiftSoup to parse HTML from a string in Swift, you first need to add the SwiftSoup dependency to your project. If you are using CocoaPods, you can add it to your Podfile:
pod 'SwiftSoup'
Or if you are using Swift Package Manager, you can add it to your Package.swift dependencies:
dependencies: [
.package(url: "https://github.com/scinfu/SwiftSoup.git", from: "2.3.2")
]
Once you have SwiftSoup integrated into your project, you can use it to parse an HTML string as follows:
import SwiftSoup
let htmlString = """
<html>
<head>
<title>Sample Title</title>
</head>
<body>
<p class="description">This is a sample paragraph.</p>
</body>
</html>
"""
do {
let doc: Document = try SwiftSoup.parse(htmlString)
let title: String = try doc.title()
let paragraph: Element? = try doc.select("p.description").first()
print(title) // Output: Sample Title
if let paragraphText = paragraph?.text() {
print(paragraphText) // Output: This is a sample paragraph.
}
} catch {
print("Error parsing HTML: \(error)")
}
In this example, we import SwiftSoup and define an HTML string. We then use SwiftSoup.parse to parse the HTML string into a Document object. We extract the title using doc.title() and find the first paragraph with a class of description using doc.select("p.description").first(). We handle potential errors using Swift's do-catch error handling.
Remember to always handle errors appropriately when working with parsing libraries, as there are many potential points of failure, such as malformed HTML or incorrect selectors.
