ADjo LABS PROJECT : Lightweight, yet powerful! Free desktop utility, for fastest validation of 'large sized' XML file/s against XSD/s. Also supports validating hundreds of XML files (multiple) as a batch against XSD/s. Corroborating the power of MSXML DOM Parser!

vbsx-Validator

Free desktop utility for simple XML/XSD validation (supports multiple XSD). Fastest XML validation of 'large sized' files (in-memory) without rendering overhead. DOM Parser based XML / XSD validation built on MSXML6. Supports full (multiple) error parsing of a given XML.

Also supports Batch (Multiple XML Files) as a single operation. Validate hundreds of XML against a single or multple XSD as one batch operation. Generates verbose log file for all operations and output.

No-frills, lightweight yet powerful! Built specifically on windows native technologies! This has no dependency on third party compiler / interpreters / engines (e.g. java, nodejs. .NET or other such runtimes). However it does utilizes some 'legacy' dependencies listed in below 'built with' sections.

Download

Please do not download from source code section as it may not be stable.

Instead use any latest stable release version, available for download from Releases section

How To run

Simply double-click the main script file named 'VBSX_Main.vbs' to launch the utility. This will launch the command line interface. Please note that you might get UAC prompt if UAC is enabled on your windows.

When running under 'Bulk File Mode', the application would auto-create a main output folder and two sub-folders (valid file folder and Invalid file folder) on your filesystem. The app would auto save the XMLs being validated appropriately into these folders based on validation result.

Note : Drag and Drop may work with UAC disabled.

Refer Wiki for usage tips, screenshots and video demo

Prerequisites

Win 7 / 8 / Server.

MSXML6 Official Download here

Require admin privileges / script execution privileges (elevated UAC prompt) on your windows system.

Technical Notes (Design)

• The Validation Parser, accepts multiple XSDs against a given XML (XMLs referencing multiple XSDs) for validation since version v2.0.1 (Multi XSD support). However the parser does not auto-import any schemas from network or filesystem, but rather considers only user supplied XSDs, hence make sure you provide all required XSDs.

• The Parser has been designed 'not to resolve externals'. It does not evaluate or resolve the 'schemaLocation' or other attributes specified in DocumentRoot for locating schemas. The reason is that most of the time schemaLocation is not always valid or resolvable as XML travels system to system. Hence this design avoids non-schema related errors.

• The parser validates strictly against the supplied XSD (schema definition) only without auto-resolving schemaLocation or other nameSpace attributes from the XML document. This provides robust validation against supplied XSD.

• The validation parser inherently validates all XML for well-formedness / structural.

• The validation parser needs Namespace (targetNamespace) which is currently extracted from the supplied XSD. Please make sure that 'targetNamespace' declaration if any, in your XSD is correct. The targetNamespace decalaration is not mandatory and hence XSD without targetNamespace are also validated properly.

• The current version does not support XML files with inline schemas

• Please refer 'Further Reading' section of Wiki for more information if required.

vbsx-validator's Issues

Include support for XMLs and XSD with noNamespace declaration

Include support for multiple XSD for XML containing / referring multiple XSDs

• Check if multiple XSDs required
• Parse each XSD for target namespace
• Add each target namespace from each XSD to schema cache.

Implement windows file explorer (chooser) for specifying filenames rather then typing on cmd interface

Extract the Namespace property from the XSDs rather then XML doc. GetNamespaceURI (ObjXML)

Currently the 'GetNamespaceURI (ObjXML)' function extracts the namespace from the XML file to be validated. Better approach would be to extract the 'targetNamespace' property from the XSD itself

For BulkFileValidation, include enhancement to auto save in valid and invalid files in different folders

In BulkFile Validation module include the enhancement to create two folders namely 'valid files' and 'invalid files' and then auto save the validated files into the appropriate folder accordingly

Need dependency check procedure (check MSXML6.0) before continuing into program

Need user input validation for SingleFileValidation() & BulkFileValidation() for console input

SingleFileValidation() & BulkFileValidation()

For both the above Subs, need to introduce error handling for user invalid user input.
Check if the user input ends with '.xml' or '.xsd'

Include support for validating XMLs with Inline Schemas

Include support for validating XMLs with Inline Schemas

Check the ParseError property (line, linepos, filepos) members if the exact line could be extracted in case of error
