Question 1

How to parse HTML from a website using Ji in Swift?

Accepted Answer

Initialize Ji with a URL, then use XPath queries to extract nodes. For example, 'let jiDoc = Ji(htmlURL: URL(string: 'http://www.apple.com')!)' and 'let title = jiDoc?.xPath('//head/title')?.first?.content' gets the page title.

Question 2

Ji vs SwiftyXMLParser for XML parsing in iOS?

Accepted Answer

Ji uses libxml2 under the hood, offering XPath support and robust HTML parsing, while SwiftyXMLParser is a pure-Swift alternative focused on simplicity. Choose Ji for XPath and cross-platform needs, but SwiftyXMLParser if you prefer no C dependencies.

Question 3

Can Ji handle malformed HTML like Python's Beautiful Soup?

Accepted Answer

Ji relies on libxml2, which has some error correction for HTML, but it's not as forgiving as Beautiful Soup. For heavily broken HTML, you might need preprocessing or a different library.

Question 4

How to install Ji with Swift Package Manager on Linux?

Accepted Answer

First install libxml2-dev via 'sudo apt-get install libxml2-dev', then add Ji as a dependency in Package.swift. The README specifies these steps for Linux compatibility.

Question 5

Does Ji support Swift concurrency with async/await?

Accepted Answer

No, Ji's API is synchronous and doesn't integrate with Swift's modern concurrency features. You'll need to handle async operations manually, like using DispatchQueue for network calls.

Question 6

What are Ji's performance implications for large XML files?

Accepted Answer

Since Ji wraps libxml2, it's generally performant, but building the entire document tree in memory can be resource-intensive for very large files. Consider streaming alternatives for gigabyte-scale data.
