Returns the current value of the parse event as a string, this returns the string value of a CHARACTERS event, returns the value of a COMMENT, the replacement value for an ENTITY_REFERENCE, the string value of a CDATA section, the string value for a SPACE event, or the String value of the internal subset of the DTD.

Usage

From source file:Main.java

public static String parseValue(XMLStreamReader xmlRdr, String elementName) throws XMLStreamException {
    String val = null;
    while (true) {
        xmlRdr.next();//from  w w w .  j av a 2 s . com
        int event2 = xmlRdr.getEventType();
        if (event2 == XMLStreamConstants.CHARACTERS) {
            val = xmlRdr.getText();
        } else if (event2 == XMLStreamConstants.END_ELEMENT && xmlRdr.getLocalName().equals(elementName)) {
            return val;
