Answer 1

Jesteś powołując

Document doc = db.parse(eventXml); 

z eventXml widocznym jako ciąg danych XML.

Jednak metoda DocumentBuilder.parse(String) oczekuje, że identyfikator URI do obciąży kod. Właśnie dlatego uzyskuje się wyjątek MalformedURLException: Java próbuje użyć Twojego XML jako identyfikatora URI.

Chcesz DocumentBuilder.parse (InputSource) lub DocumentBuilder.parse (InputStream). InputStream można utworzyć z Twojego String/StringBuffer przy użyciu np.

new InputSource(new StringReader(xmlString)) 

(untested).

Answer 2

parse() nie przyjmuje rzeczywistego XML jako parametru, zamiast tego pobiera adres URL do dokumentu.

Należy użyć
DocumentBuilder.parse(new StringBufferInputStream(eventXml));

Answer 3

Wysłany tak dużo treści, ale nic, co może pomóc każdy czytelnik, aby zobaczyć to, co staraliśmy się zrobić. Jeśli problem polega tylko na tym, że analizowanie XML daje ci problem, sprawdź, czy Twój plik XML jest dobrze sformułowany.

Answer 4

Ten fragment powinien zadziałać.

private String updateMyXML(String orderXML) { 
    javax.xml.parsers.DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); 
    InputSource inputSource = new InputSource(new StringReader(orderXML)); 
} 

Answer 5

Zamiast db.parse(eventXml), spróbuj:

Document doc = db.parse(new InputSource(new StringReader(eventXml)));
