DocStax2Validation

hi,dude,i wanna ask some questions about WSTX's validation ability.

i mean i hava got multiple xsd files,and wanna use WSTX to validate the xml files,but there is a problem that i 'm not sure that whether WSTX can support multiple validation xsd files as a group to validate xml files.here is my codes,only work when there is one xsd file.but my situtation is one xsd file linked to another one ,and so on.

package samples;

import java.io.File;

import javax.xml.stream.*;

import org.codehaus.stax2.*;
import org.codehaus.stax2.validation.*;

/**
* This is a simple example command line utility, that shows how to
* use the new Stax2 validation API to validate input documents against
* specific DTD instance.
*/
public class ValidateWithDtd
{
public static void main(String[] args)
{
if (args.length != 2) {
System.err.println("Usage: java ValidateWithDtd [input-file] [dtd-file]");
System.exit(1);
}
// First, let's parse DTD schema object
XMLValidationSchemaFactory sf = XMLValidationSchemaFactory.newInstance(XMLValidationSchema.SCHEMA_ID_W3C_SCHEMA);
File schemaFile = new File(args[1]);
///File schemaFile2 = new File(args[2]);
XMLValidationSchema xsd= null;
///XMLValidationSchema xsd2= null;

try {
xsd= sf.createSchema(schemaFile);
// xsd2= sf.createSchema(schemaFile2);//can't work 
} catch (XMLStreamException xe) {
System.err.println("Failed to process the DTD file ('"+schemaFile+"'): "+xe);
System.exit(1);
}

// And then validate a document:
File inputFile = new File(args[0]);
try {
XMLInputFactory2 ifact = (XMLInputFactory2)XMLInputFactory.newInstance();
XMLStreamReader2 sr = ifact.createXMLStreamReader(inputFile);

try {
sr.validateAgainst(xsd);
// sr.validateAgainst(xsd2);// can 't work 
/* Document validation is done as document is read through (ie.
* it's fully streaming as well as parsing), so just need to
* traverse the contents.
*/
while (sr.hasNext()) {
sr.next();
}
} catch (XMLValidationException vex) {
System.err.println("Document '"+inputFile+"' failed validation: "+vex);
System.exit(1);
}
} catch (XMLStreamException xse) {
System.err.println("Failed parse the input document ('"+inputFile+"'): "+xse);
System.exit(1);
}
System.out.println("Document '"+inputFile+"' succesfully validated.");
}
}

it seems that WSTX's API don't support multiple xsd&dtd files as a group to validate xml files.

please help me,thank you!!!

you'd better send me in the email:shuoleo@126.com
