XMLQuire

XMLQuire is a feather-light software application that gives you the possibility to seamlessly edit XML files. It offers support for syntax highlighting and automatic code completion.

As long as you have .NET Framework installed on your PC, you don't need to set up anything else. You can drop the executable file anywhere on the disk and just click it to launch XMLQuire, as well as save it to an external storage unit to directly run it on any PC. Unlike most installers, it doesn't modify Windows registry settings.

The interface is comfortable and easy to navigate, enabling you to open an XML file to edit, or to create a new one from scratch.

You can launch multiple XMLQuire instances, edit code while keeping an eye on the status bar for any errors, use a search function when dealing with large amounts of data, as well as review XPath axes, functions, operators and schema types.

Undoing and redoing actions is possible, so you can fix any mistakes. What's more, you can increase or decrease the indent, add comments, or format the XML code by trimming the left indentation, normalizing text or attribute line breaks, or by separating XML blocks.

The tool is optimized for widescreen monitors and preserves whitespace. You can enable word wrapping mode, as well as disable XML schema or DTD validation. These are just some of the options available.

We haven't come across any difficulties in our tests, thanks to the fact that XMLQuire didn't hang, crash or display errors. It had a good response time and low impact on computer performance, using low CPU and memory.

This software application comes loaded with handy options and configuration settings for editing XML files, and it's wrapped in a user-friendly interface. Too bad it hasn't been recently updated.
