我使用以下代码来针对指定的XML架构验证XML文档(.gpx)。我将架构存储在本地作为.xsd文件。问题是,此方法使用Internet连接来验证架构。有没有办法我可以不使用互联网连接? (鉴于我在本地存储XML模式这一事实。)
代码:
public static boolean validate(String XmlDocumentUrl, String SchemaUrl) {
SAXParser parser = new SAXParser();
try {
parser.setFeature("http://xml.org/sax/features/namespaces", true);
parser.setFeature("http://xml.org/sax/features/validation", true);
parser.setFeature(
"http://apache.org/xml/features/validation/schema", true);
parser.setFeature(
"http://apache.org/xml/features/validation/schema-full-checking",
false);
parser.setProperty(
"http://apache.org/xml/properties/schema/external-schemaLocation",
SchemaUrl);
Validator handler = new Validator();
parser.setErrorHandler(handler);
parser.parse(XmlDocumentUrl);
if (handler.validationError == true){
System.out.println("XML Document has Error:"
+ handler.validationError + ""
+ handler.saxParseException.getMessage());
return false;
}
else{
System.out.println("XML Document is valid");
return true;
}
} catch (java.io.IOException ioe) {
System.out.println("IOException" + ioe.getMessage());
} catch (SAXException e) {
System.out.println("SAXException" + e.getMessage());
}
return false;
}
谢谢和问候,

使用“file://”网址引用您的本地架构。

将schemaUrl
指定为"file://path/to/schema.xsd"
。

Yoy可以通过你自己的DefaultHandler实现:
...SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(InputSource, new Defaulthandler() {
@Override
public InputSource resolveEntity(String publicId, String systemId)
throws IOException, SAXException {
InputStream is = ClassLoader.getSystemResourceAsStream("path_to_you_local_dtd_doc");
return is != null ? new InputSource(is) :
super.resolveEntity(publicId, systemId);
}
} )
