DocumentBuilder.parse kullanarak iyi biçimlendirilmiş XML ayrıştırırken doğrulamayı nasıl kapatabilirim?

Question

Java kullanıyorum 6. İyi oluşturduğumu bildiğim XHTML'yi ayrıştırmak istiyorum. Bu nedenle, DTD'ye veya dokümanda atıfta bulunulan diğer şemalara karşı herhangi bir doğrulama yapmak istemiyorum. Ancak, bu doğrulamayı nasıl devre dışı bırakacağımı bulmakta zorlanıyorum. Ben

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
    factory.setValidating(false); 
    final DocumentBuilder b = factory.newDocumentBuilder(); 
    final InputSource s = new InputSource(new StringReader(str)); 
    org.w3c.dom.Document result = b.parse(s); 

var Ama hala

benim ayrıştırıcı internete gidiş istemezler ... son satırında istisna olsun. Bunu nasıl devre dışı bırakırım? Teşekkürler, - Dave

Düzenleme: Başına Traroth önerisi, ben aşağıdaki kodu çalıştı, ancak aynı durum Muhtemelen EntityResolver konuyla ilgili

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
    factory.setValidating(false); 
    final DocumentBuilder builder = factory.newDocumentBuilder(); 
    builder.setEntityResolver(new EntityResolver() { 
     @Override 
      public InputSource resolveEntity(String publicId, String systemId) { 
        return null; 
      } 
     }); 
    final InputSource s = new InputSource(new StringReader(str)); 
    org.w3c.dom.Document result = builder.parse(s);

Answer 2

Eğer DTDlerinden dahil, TÜM dış başvurulan varlıkları yok sayacak bir DocumentBuilder'ı oluşturmak nasıl:

görüntülenmesine veya isValidating log ne olur

final DocumentBuilder builder = factory.newDocumentBuilder(); 
builder.setEntityResolver(new EntityResolver() { 
    @Override 
     public InputSource resolveEntity(String publicId, String systemId) { 
       // it might be a good idea to insert a trace logging here that you are ignoring publicId/systemId 
       return new InputSource(new StringReader("")); // Returns a valid dummy source 
     } 
    });
