Welcome to the world of Fuzi, a sleek and speedy XML/HTML parser written in Swift! In this guide, we will delve into how to set up and utilize Fuzi, so you can handle XML and HTML documents with ease. Consider Fuzi your trusty sidekick, making your coding life smoother and more enjoyable.

Getting Started with Fuzi

Before diving into coding, you need to install Fuzi in your project. Let’s explore the installation methods:

Installation Methods

• Using CocoaPods: Add Fuzi to your Podfile:

platform :ios, 8.0
use_frameworks!
target 'MyApp' do
    pod 'Fuzi', '~> 1.0.0'
end

Then, run the following command:

$ pod install

• Using Swift Package Manager: Open Xcode, choose File > Swift Packages > Add Package Dependency, and use https://github.com/cezheng/Fuzi.
• Manually: Add all *.swift files from the Fuzi directory into your project and set the header search paths in Build Settings.
• Using Carthage: Create a Cartfile and run the command $ carthage update. Then follow up by dragging the Fuzi.framework into your project.

How to Use Fuzi

Let’s break down how to use Fuzi effectively by understanding its key features through an analogy.

Understanding the Parsing Process with an Analogy

Imagine you’re a librarian (Fuzi) receiving a large box of books (XML/HTML documents) that you need to organize. Your job is to carefully examine each book, noting the title, author, and other details (elements and attributes).

• **Finding the Books:** You start by opening the box and picking out books that have a specific genre (accessing the root element).
• **Categorizing Your Collection:** You can review all the information contained in the books, such as summaries and publication dates (accessing child nodes and attributes).
• **Locating Specific Titles:** If a librarian wants to find a book with a certain title, they could use a catalog system (XPath and CSS queries).

In coding terms, here’s how you would write this using Fuzi:

import Fuzi

let xml = "100"

do {
    let document = try XMLDocument(string: xml)
    if let root = document.root {
        // Access all child nodes
        for element in root.children {
            print("\(element.tag): \(element.attributes)")
        }
        // Getting child element by tag
        if let length = root.firstChild(tag: "Length") {
            print(length["unit"]) // unit attribute
        }
    }
} catch let error {
    print(error)
}

Troubleshooting

Here are some common issues you may encounter while using Fuzi and their solutions:

• Issue: “Attempt to access a node that doesn’t exist.”
• Solution: Ensure that the XML/HTML input is well-formed and check the tag names you’re querying.
• Issue: “CocoaPods fails to install Fuzi.”
• Solution: Make sure you have the latest version of CocoaPods installed. You can check using pod --version.
• Issue: “Unexpected error when parsing.”
• Solution: Review the error handling in your code—using try statements properly will help catch the precise error.
