I can't write correctly words to xml using StAX

问题

I have a problem, I want to get something like this:

<text>
<sentence>
    <word>a</word>
    <word>had</word>
    <word>lamb</word>
    <word>little</word>
    <word>Mary</word>
</sentence>
<sentence>
    <word>Aesop</word>
    <word>and</word>
    <word>called</word>
    <word>came</word>
    <word>for</word>
    <word>Peter</word>
    <word>the</word>
    <word>wolf</word>
</sentence>
<sentence>
    <word>Cinderella</word>
    <word>likes</word>
    <word>shoes</word>
</sentence>

but I get only this:

  <text>
<sentence>
    <word>a</word>
    <word>had</word>
    <word>lamb</word>
    <word>little</word>
    <word>Mary</word>
</sentence></text>

Example text

“ Mary had a little lamb .

Peter called for the wolf , and Aesop came . Cinderella likes shoes..”

And my class

public class StaxWriteXmlTest {

/**

 * @throws FileNotFoundException
 * @throws XMLStreamException

public static void main(String[] args) throws FileNotFoundException,
        XMLStreamException {

    // xml event writer with output stream
    XMLOutputFactory xmlOutFactory = XMLOutputFactory.newInstance();
    OutputStream outputStream = new FileOutputStream(itemXmlFile);
    XMLEventWriter eventWriter = xmlOutFactory
            .createXMLEventWriter(outputStream);
    ByteArrayOutputStream outStream = new ByteArrayOutputStream();
    XMLEventWriter xmlWrite = (XMLOutputFactory.newInstance())
            .createXMLEventWriter(outStream);

    XMLEventFactory eventFactory = XMLEventFactory.newInstance();
    XMLEvent end = createNewLine(eventFactory);
    XMLEvent tab = createTab(eventFactory);

    // Create start tag
    StartDocument startDocument = eventFactory.createStartDocument();
    EndDocument endDocument = eventFactory.createEndDocument();
    eventWriter.add(startDocument);

    // create config open tag
    eventWriter.add(end);
    StartElement configStartElement = eventFactory.createStartElement("",

    eventWriter.add(configStartElement);
    eventWriter.add(end);





    eventWriter.add(tab);
    StartElement itemStartElement = eventFactory.createStartElement("", "",

    eventWriter.add(itemStartElement);
    eventWriter.add(end);
    eventWriter.add(tab);

    // add words
    for (String words : word) {
        eventWriter.add(tab);
        createItemNode(eventFactory, eventWriter, "word", words);
        eventWriter.add(tab);
    }
    // eventWriter.add(tab);
    EndElement itemEndElement = eventFactory.createEndElement("", "",

I haven't parsed through all your code, but this section looks suspicious:

String[] splitText = allTogether.split("[.]");
for (int i = 0; i < splitText.length; i++) {
    // System.out.println(splitText[i]);
    String[] nexSplit = splitText[i].split("[ \t]");

    for (int x = 0; x < nexSplit.length; x++) {
        Arrays.sort(nexSplit, String.CASE_INSENSITIVE_ORDER);
        // System.out.println(nexSplit[x]);

        return nexSplit;

    }

}
return splitText;

Do you really want to return in that inner loop after one iteration? I doubt it.

Also, make sure to close your reader in your initItems() method.
