SAX handler. package = org.xml.saxIt is strange concept initially, but easy enough once you get hands on and do it.
Here is an example of a simple handler that parses a specific XML response to create a dictionary using the element names as keys and the element content as values:
SatoriZipTaskSaxHandler.java
Description: Binary data
and here is an example of a method that uses that handler to parse a xml response from an input stream buffered Reader and return the resulting dictionary.
protected NSDictionary<String, String> parseResponse(Reader responseReader) {
XMLReader reader = WKXMLUtilities.createXMLReader();
SatoriZipTaskSaxHandler handler = new SatoriZipTaskSaxHandler();
reader.setContentHandler(handler);
// Convert responseReader into an InputSource
InputSource inputSource = new InputSource(responseReader);
try {
reader.parse(inputSource);
} catch (IOException e) {
throw new NestableRuntimeException(e);
} catch (SAXException e) {
throw new NestableRuntimeException(e);
}
NSDictionary<String, String> results = handler.results();
return results;
}
It parses responses sth like this that I receive from a remote service

ANyway, hope that helps a little,
