Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

firstobject XML Editor, also called foxe, is a free Windows desktop editor for XML, HTML, loosely formed markup, and text files. It is aimed at users who need structured XML navigation alongside conventional text editing, particularly when documents require formatting, encoding conversion, validation, or work with large files. The portable single-executable design and permission for commercial use make it suitable for carrying between Windows systems or adding to an existing technical workflow without a paid tier.

Its strongest area is XML-focused editing depth. The editable and customizable tree view provides a structured way to navigate documents, while formatting, aligning, indentation, syntax coloring, and word wrap support day-to-day editing. MSXML-based DTD validation helps check document structure, and XSLT transformation support extends the tool beyond direct text changes. FOAL scripting uses C++-style syntax for users who need automation within the editor. Encoding selection and conversion, Unicode character functions, printing, and support for files exceeding 100 MB round out a focused XML toolkit.

The trade-off is breadth and platform scope. The Free plan includes the Windows desktop editor, portable executable, XML tree editing, syntax coloring, word wrap, FOAL scripting, and commercial use, with no paid tiers described. That makes the product a practical choice for Windows users whose work centers on XML or related markup. It is less suitable for people seeking a cross-platform editor, a broad general-purpose development environment, or AI-assisted editing. The official listing identifies version 2.4.2.431, released 23-Apr-2011, so buyers who prioritize frequent releases may prefer a more actively updated alternative.
