SAX succeeds, but StAX fails

Question

Hy!
I tried to parse PubMed (a biomedical article database) with SAX and
also StAX. The last one failed, but I am not sure why (see Exception
below).
Why does SAX succeed and StAX don't? The XML document seems to be fine (see
http://www.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&retmode=xml&id=11748933
Any suggestions?

StAX example:
String address = "http://www.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&retmode=xml&id=11748933";
URL url = new URL(address);
XMLInputFactory factory = XMLInputFactory.newInstance();
XMLStreamReader parser = factory.createXMLStreamReader(url.openConnection().getInputStream());
while(parser.hasNext()) {
       switch(parser.getEventType()) {
        parser.next();
}Error message:
javax.xml.stream.XMLStreamException: ParseError at [row,col]:[50,39]
Message: A '(' character or an element type is required in the
declaration of element type "PubMedPubDate".
SAX example:
SAXParserFactory parserFactory = SAXParserFactory.newInstance();
parserFactory.setValidating(true);
parserFactory.setNamespaceAware(true);
SAXParser parser = parserFactory.newSAXParser();
parser.parse(url.openConnection().getInputStream(), new
PubmedEFetchHandler());(PubmedEFetchHander is a simple DefaultHandler with some debugging
output).

Answer 1

Have you looked at the usual suspects, such as disk space, file permissions etc.?
Generally, if/when one of the tools fails, I run it from the command line. To figure out the command line, take a look in the log file and you'll see the command that it ran. By running it from the command line, you usually get a better idea of why it failed.
