契约
- XMLParser parses single-child elements into plain objects rather than 1-element arrays by default, causing array methods like map to throw TypeError, unless the isArray callback explicitly returns true for the tag or jPath.
- An XML document with multiple same-name sibling tags produces an Array by default without requiring the isArray option.
- The isArray callback receives tagName, jPath, isLeafNode, and isAttribute arguments during parsing to selectively enforce array wrapping.
- When isAttribute is true, the isArray callback forces attribute values into single-element arrays.
- Single-element nodes configured via isArray maintain array methods like map and filter without requiring runtime type guards.
