Simple XML Validator

Simple XML Validator is a simple-to-use application made in Java for web developers, which can automatically evaluate XML expressions and reveal possible errors and warnings. It doesn't have complex options or customization settings, making it suitable even for users less experienced with this kind of software.

Old, yet functional Java-based utility

The tool hasn't received updates for a long time, and it's necessary to put in on Java's exception list to be able to launch it with the latest edition of the Java Runtime Environment due to security reasons. Otherwise, the setup operation is speedy and uneventful.
When it comes to the interface, Simple XML Validator adopts a single window with a minimalistic appearance, where you can resort to the built-in file browser to locate and add an XML file from the local disk, removable drive, or network location. Otherwise, you can drag and drop items into the central window while navigating disk directories in Windows Explorer.

Drop and evaluate XML files

The XML code is automatically verified by the application. Results show the analysis time and description of each error, together with the total elements, characters, nesting, and maximum nesting.
There is no detailed information available, and the program doesn't implement options for printing or exporting data to file. However, it's possible to select and copy text by triggering the Ctrl+C hotkey, as there is no context menu available.

Evaluation and conclusion

Simple XML Validator was stable throughout its runtime in our testing. Although it hasn't been updated for considerable time, we haven't experienced any compatibility issues with the newest Windows or Java. It verified XML expressions quickly while consuming low CPU and RAM.
All in all, Simple XML Validator is a pretty basic software utility for discovering faulty XML code, but it's fast and can give you a hand.
