xsd-validator
Quick and easy validation of XML files against XML schema (xsd files).
Requires Java to be installed.
Usage on Mac and Linux:
./xsdv.sh test.xsd test.xml
Usage from a Windows command prompt:
xsdv test.xsd test.xml
If you find it useful and want to install system wide (Linux/Mac only):
sudo ant install
xsdv test.xsd test.xml
Note this project is just a simple wrapper around the standard Java library routines for XML Schema validation.
