Swifty XML Parsing (SwiftyXML)

This skill provides expert knowledge on parsing, querying, and constructing XML data using the SwiftyXML library. Use this when handling SVG XML, configuration files, or any structured XML content.

Core Responsibilities

• Ergonomic Access: Use @dynamicMemberLookup and subscripts for intuitive XML traversal.
• Typed Extraction: Safely convert XML nodes/attributes to Swift types (Int, Double, Bool, Date, etc.).
• Chain Validation: Use the .null result type to handle missing XML nodes gracefully without force-unwrapping.

Traversal Patterns

Common Procedures

Parsing XML from String

let xml = try XML(xmlString: "<root><item id='1'>Text</item></root>")
let id: Int? = xml.root.item.$id.int

Handling Missing Data

Always prefer optional extraction:

if let name = xml.user.profile.$name.string {
    // Process name
}

Iteration

XML objects conform to Sequence of their children:

for child in xml.items.children {
    print(child.name)
}
