I am trying to validate xml with a schema on the fly. I have been using the Sax parser. I am reading the schema from a db so I have it as a string. The code below works if the schema if specified as a URI. Is there any way to specify the schema as an InputStream? As I can't create tempory files on the server I need some other way. Any help is appriciated Thanks Stephen public static boolean validateSax(String xml, String schema){ try { XMLReader reader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser"); reader.setFeature("http://xml.org/sax/features/validation",true); reader.set   More>>

public static boolean validateSax(String xml, String schema){


try {

XMLReader reader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
reader.setFeature("http://xml.org/sax/features/validation",true);
reader.setFeature("http://apache.org/xml/features/validation/schema",true);
reader.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",schema);

reader.parse(new InputSource(new ByteArrayInputStream(xml.getBytes())));

} catch (SAXException e) {
return false
} catch (IOException e) {
return false
}

return true;

}
