Description

Hi,

I'm trying to parse (even mime type detect) some XML file that it's not large, but kinda tricky and my process hangs on :

XMLStringBuffer.append(char[], int, int) line: not available
XMLStringBuffer.append(XMLString) line: not available
XMLNSDocumentScannerImpl(XMLScanner).scanAttributeValue(XMLString, XMLString, String, boolean, String) line: not available
XMLNSDocumentScannerImpl.scanAttribute(XMLAttributesImpl) line: not available
XMLNSDocumentScannerImpl.scanStartElement() line: not available
XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook() line: not available
XMLNSDocumentScannerImpl$NSContentDispatcher(XMLDocumentFragmentScannerImpl$FragmentContentDispatcher).dispatch(boolean) line: not available
XMLNSDocumentScannerImpl(XMLDocumentFragmentScannerImpl).scanDocument(boolean) line: not available

Please see attached XML file.

Please advise.

Thanks
