Validate XML to XSD with XMLLINT on CLI


I was looking for a nice tool to validate my XML messages against an XML Schema, when I ran into this command where you can really easily validate on the command line. That’s really cool since we’re becoming CLI ninjas anyway!

Update: This also works on Windows with this little gem.

The command is as follows:

xmllint --noout --schema schema.xsd ./message.xml

Which delivered the following output:

joris@jorislatitude:~/workspaces/_examples/XSD$ xmllint --noout --schema sample_schema.xsd ./messageone.xml 
./messageone.xml:2: element S_UNB: Schemas validity error : Element 'S_UNB': This element is not expected. Expected is ( INSDES ).
./messageone.xml fails to validate

As shown in above message, my example failed to validate, which is what I suspected, but now I can send my integration partner a better and really precise explanation! As said above: Awesomeness! :-)

Create sample XML message from XSD in Eclipse (Free solution!)

On an Oracle Service Bus project you are often supplied with XSD’s or WSDL’s when you’re integrating with clients. The customer or client expects you to test their web service but before you do, you might want to take a look at the XML which should be sent to make sure you’re sending compliant XML.

One way to do this is by importing the WSDL in SoapUI and creating sample test requests, this comes in quite handy when you are actually using a WSDL, but what if the customer only supplies an XSD? SoapUI does not support creating sample XML from an XSD element.
There are several commercial products which can solve this problem but if you’re only looking for generating sample XML messages from XSD, you might want to look at using Eclipse’s built in XML generating option:

First step is to import the XSD in your project, the right click the Schema and select “Generate” and then “XML”

You will be presented with a “New XML file” dialogue which lets you save your new XML sample. Choose any location you want, and click “Next”. Then you will be presented with the options for your new XML sample. Select the options you desire and press “Finish”

Your new XML file has been generated and ofcourse is compliant with your XSD right now!
