Understanding Modern XML Transformation

Attribute vs. Element Disambiguation

In XML, an element can have attributes (<user id="1">) and child tags (<id>1</id>). Our converter applies an attribute prefix like @_ to ensure keys never collide.

Automatic Repeating Array Detection

When sibling elements share identical tag names (e.g., multiple <item> tags in an RSS channel), they are automatically grouped into a clean JavaScript array.

Safe In-Browser DOMParser

Uses the browser's sandboxed DOMParser API, isolating parsing from network entities and mitigating Billion Laughs XML entity expansion threats.
