How to Open, Format and Read an XML File on iPhone

Short answer: to open an XML file on an iPhone, use an XML viewer app. XML Viewer and Editor opens any XML file as a collapsible tree or with syntax highlighting, validates it as you edit, and can format or minify it in one tap. It is free to download and needs no account.

Why you need a dedicated app

iOS can preview some documents, but an XML config, API response or data feed usually opens as a wall of unindented text. A viewer adds structure so you can actually read it.

How to open and read an XML file on iPhone

Install an XML viewer from the App Store.
Open the file from Files, a Mail attachment or the share sheet, or paste the XML straight in.
Switch between tree view (collapse and expand nodes) and highlighted text view.
Tap a value to copy it, and use the breadcrumb to see where you are in a deep structure.

Useful features for working with XML on a phone

Tree view with colour-coded elements, attributes and text.
Syntax highlighting, auto-indentation and line numbers.
Built-in editor with real-time validation, so malformed XML is flagged as you type.
Format or minify with one tap.
XPath search to find elements, attributes and values across a large document.
XML diff to compare two documents side by side and see additions, deletions and changes.
