a chunk xml file this

i have 2 major problem
1) need obtain xsd file name xml , xml big 1/2gb (stax/sax nice solution)
2) need load xsd jar because whole app cannot have access file system.
for validation prefer system http://www.edankert.com/validate.html
i read include in answer problem validating xml file using java xsd having include
but using loader can't obtain infos file.
some idea?

1.) filename not inside xml...you should know filename of xml other means (user input, hardcoded, etc.). if have directory full of xml files, run loop on files. pseudo code:
for(getnextfile) { if(xmlvalidationwithxsd(nextfile)) //passed validation else //failed validation } i run scripts move xml files 1 place xml-only folder.
2.) believe streamsource allows this. here's did recently:
public static boolean xmlvalidationwithxsd(string xmllocation){ source xmlfile = new streamsource(new file(xmllocation)); //important: here need. multiple xsds (that relate each other) , getresource access form .jar files //treat xsd resource found in class path, assume full package name passed in xsdlocation source schemafilesource1 = new streamsource(benefitenrollmentrequestfileutil.class.getresource(new_xsd_file_resource1).tostring()); source schemafilesource2 = new streamsource(benefitenrollmentrequestfileutil.class.getresource(new_xsd_file_resource2).tostring()); source[] schemafilesources = {schemafilesource1, schemafilesource2}; schemafactory schemafactory = schemafactory.newinstance(xmlconstants.w3c_xml_schema_ns_uri); try { schema schema = schemafactory.newschema(schemafilesources); validator validator = schema.newvalidator(); validator.validate(xmlfile); return true; } catch (saxexception e) { logger.debug(xmlfile.getsystemid() + " not valid", e); logger.debug("reason: " + e.getlocalizedmessage()); } catch (ioexception e) { logger.debug(xmlfile.getsystemid() + " not valid", e); logger.debug("reason: " + e.getlocalizedmessage()); } return false; } sources:
referencing xsd schema within jar file
problem validating xml file using java xsd having include
edit:
the relation between file list contained in first tag have list of xsd use , first xsd 1 has same namesace first tag
