You write a trivial java program like this:

Compile and run it like this (notice xerces.jar and xml-apis.jar are
needed):

C:\xml>javac -classpath
.;c:\thirdparty\apache\xerces.jar;c:\thirdparty\apache\x
ml-apis.jar SchemaValidate.java

C:\xml>java -classpath
.;c:\thirdparty\apache\xerces.jar;c:\thirdparty\apache\xm
l-apis.jar SchemaValidate editor99.xml
Error:  org.xml.sax.SAXParseException: Datatype error: In element
'allowNull' :
tru is not a boolean.


NOtice that editor99.xml failed validation.  Here is editor99.xml and
editor.xsd which it validates against (note the xsi:schemaLocation is
defined in the .xml file):

------
editor.xml

<!DOCTYPE htmlEditor >

      </htmlType>
      <allowNull>tru</allowNull>

Subject: XML Schema validation using JAXP Q?


Hi all,
I would like to ask if it is possible to validate xml document against XML
Schema using JAXP? At the moment I am using XALAN and it should be XML
Schema aware, but I have no clue how to do the vlidation using JAXP.

Any help appreciated,

Jaub
