Question 1

How do I parse an XML file with Ono in Swift?

Accepted Answer

Load the XML data into a Data object, then use ONOXMLDocument.XMLDocument(with: data) to create a document. From there, traverse elements using properties like rootElement and children, or query with XPath/CSS selectors, as shown in the Swift example in the README.

Question 2

Is Ono better than NSXMLParser for iOS apps?

Accepted Answer

Ono provides a more intuitive DOM-style API compared to NSXMLParser's event-driven model, making it easier for common parsing tasks like web scraping. However, NSXMLParser might be more memory-efficient for streaming or very large documents due to its SAX-style approach.

Question 3

Does Ono support HTML5 parsing?

Accepted Answer

Yes, Ono uses libxml2 for parsing, which has good HTML support including HTML5. The library can handle HTML documents loaded from strings or data, as indicated in the features for flexible loading and query support.

Question 4

How to handle XML namespaces in Ono?

Accepted Answer

Ono has correct handling of XML namespaces with methods like firstChildWithTag:inNamespace:, allowing precise querying of elements within specific namespaces, as demonstrated in the Objective-C example with the 'dc' namespace.

Question 5

What are the memory usage implications of using Ono?

Accepted Answer

Since Ono uses DOM-style parsing, it loads the entire document into memory, which can lead to high memory consumption for large documents. This makes it less ideal for apps with strict memory constraints or those processing massive files.

Question 6

Can I use Ono in a macOS command-line tool?

Accepted Answer

Yes, Ono is compatible with macOS 10.7 and higher, so it can be used in command-line tools or any macOS application. Installation via CocoaPods or manual linking of libxml2 is required, as specified in the requirements.
