Answer 1

está invocando

Document doc = db.parse(eventXml); 

con eventXml aparentemente siendo una cadena de datos XML.

Sin embargo, el método DocumentBuilder.parse(String) espera un URI a carga el XML de. Es por eso que obtienes una excepción MalformedURLException: Java intenta usar tu XML como un URI.

Desea DocumentBuilder.parse (InputSource) o DocumentBuilder.parse (InputStream). El InputStream se puede crear a partir de su String/StringBuffer usando, p. Ej.

new InputSource(new StringReader(xmlString)) 

(no probado).

Answer 2

parse() no toma el XML real como parámetro, sino que lleva la URL a un documento.

Debe utilizar
DocumentBuilder.parse(new StringBufferInputStream(eventXml));

Answer 3

que han publicado tanto contenido, pero nada de lo que puede ayudar a cualquier lector a ver lo que estaba tratando de hacer. Si su problema es solo que el análisis XML le está dando un problema, entonces verifique que su XML esté bien formado.

Answer 4

Este fragmento debería funcionar.

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

Answer 5

En lugar de db.parse(eventXml), probar:

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