Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

Jackson also allows you to parse or generate XML messages with the Jackson Dataformat XML Extension.

Jackson Dataformat XML Source Code files are provided in the source packge (jackson-dataformat-xml-2.14.0-sources.jar). You can download it at Jackson Maven Website.

 */
public class XmlInfo
{
    protected final String _namespace;
    protected final boolean _isAttribute;
    protected final boolean _isText;
    protected final boolean _isCData;
    
    public XmlInfo(Boolean isAttribute, String ns, Boolean isText, Boolean isCData)
    {
        _isAttribute = (isAttribute == null) ? false : isAttribute.booleanValue();
        _namespace = (ns == null) ? "" : ns;
        _isText = (isText == null) ? false : isText.booleanValue();
        _isCData = (isCData == null) ? false : isCData.booleanValue();
    }

    public String getNamespace() { return _namespace; }
    public boolean isAttribute() { return _isAttribute; }
    public boolean isText() { return _isText; }
    public boolean isCData() { return _isCData; }
