public class Element extends Node
In order to create an element, please use the createElement method instead of invoking the constructor directly. The right place to add user defined initialization code is the init method.

Fields Summary

Constructors Summary
public Element()

Methods Summary
public voidclear()
removes all children and attributes

        attributes = null;
        children = null;
public org.kxml2.kdom.ElementcreateElement(java.lang.String namespace, java.lang.String name)
Forwards creation request to parent if any, otherwise calls super.createElement.


        return (this.parent == null)
            ? super.createElement(namespace, name)
            : this.parent.createElement(namespace, name);
public intgetAttributeCount()
Returns the number of attributes of this element.

        return attributes == null ? 0 : attributes.size();
public java.lang.StringgetAttributeName(int index)

        return ((String []) attributes.elementAt (index)) [1];
public java.lang.StringgetAttributeNamespace(int index)

        return ((String []) attributes.elementAt (index)) [0];
public java.lang.StringgetAttributeValue(int index)

        return ((String []) attributes.elementAt (index)) [2];
public java.lang.StringgetAttributeValue(java.lang.String namespace, java.lang.String name)

        for (int i = 0; i < getAttributeCount (); i++) {
            if (name.equals (getAttributeName (i)) 
                && (namespace == null || namespace.equals (getAttributeNamespace(i)))) {
                return getAttributeValue (i);
        return null;            
public java.lang.StringgetName()
returns the (local) name of the element

        return name;
public java.lang.StringgetNamespace()
returns the namespace of the element

        return namespace;
public intgetNamespaceCount()
returns the number of declared namespaces, NOT including parent elements

        return (prefixes == null ? 0 : prefixes.size ());
public java.lang.StringgetNamespacePrefix(int i)

        return ((String []) prefixes.elementAt (i)) [0];
public java.lang.StringgetNamespaceUri(java.lang.String prefix)
returns the namespace for the given prefix

        int cnt = getNamespaceCount ();
        for (int i = 0; i < cnt; i++) {
            if (prefix == getNamespacePrefix (i) ||
                (prefix != null && prefix.equals (getNamespacePrefix (i))))
                return getNamespaceUri (i);    
        return parent instanceof Element ? ((Element) parent).getNamespaceUri (prefix) : null;
public java.lang.StringgetNamespaceUri(int i)

        return ((String []) prefixes.elementAt (i)) [1];
public org.kxml2.kdom.NodegetParent()
Returns the parent node of this element

        return parent;
public org.kxml2.kdom.NodegetRoot()
Returns the root node, determined by ascending to the all parents un of the root element.

        Element current = this;
        while (current.parent != null) {
            if (!(current.parent instanceof Element)) return current.parent;
            current = (Element) current.parent;
        return current;
public voidinit()
called when all properties are set, but before children are parsed. Please do not use setParent for initialization code any longer.

public voidparse(org.xmlpull.v1.XmlPullParser parser)
Builds the child elements from the given Parser. By overwriting parse, an element can take complete control over parsing its subtree.

        for (int i = parser.getNamespaceCount (parser.getDepth () - 1);
            i < parser.getNamespaceCount (parser.getDepth ()); i++) {
            setPrefix (parser.getNamespacePrefix (i), parser.getNamespaceUri(i));
        for (int i = 0; i < parser.getAttributeCount (); i++) 
            setAttribute (parser.getAttributeNamespace (i),
//                          parser.getAttributePrefix (i),
                          parser.getAttributeName (i),
                          parser.getAttributeValue (i));

        //        if (prefixMap == null) throw new RuntimeException ("!!");


        if (parser.isEmptyElementTag()) 
            parser.nextToken ();
        else {
            parser.nextToken ();

            if (getChildCount() == 0)
                addChild(IGNORABLE_WHITESPACE, "");
        parser.nextToken ();
public voidsetAttribute(java.lang.String namespace, java.lang.String name, java.lang.String value)
Sets the given attribute; a value of null removes the attribute

        if (attributes == null) 
            attributes = new Vector ();

        if (namespace == null) 
            namespace = "";
        for (int i = attributes.size()-1; i >=0; i--){
            String[] attribut = (String[]) attributes.elementAt(i);
            if (attribut[0].equals(namespace) &&
                if (value == null) {
                else {
                    attribut[2] = value;

            (new String [] {namespace, name, value});
public voidsetName(java.lang.String name)
sets the name of the element = name;
public voidsetNamespace(java.lang.String namespace)
sets the namespace of the element. Please note: For no namespace, please use Xml.NO_NAMESPACE, null is not a legal value. Currently, null is converted to Xml.NO_NAMESPACE, but future versions may throw an exception.

        if (namespace == null) 
            throw new NullPointerException ("Use \"\" for empty namespace");
        this.namespace = namespace;
protected voidsetParent(org.kxml2.kdom.Node parent)
Sets the Parent of this element. Automatically called from the add method. Please use with care, you can simply create inconsitencies in the document tree structure using this method!

        this.parent = parent;
public voidsetPrefix(java.lang.String prefix, java.lang.String namespace)
Sets the given prefix; a namespace value of null removess the prefix

        if (prefixes == null) prefixes = new Vector ();
        prefixes.addElement (new String [] {prefix, namespace});        
public voidwrite(org.xmlpull.v1.XmlSerializer writer)
Writes this element and all children to the given XmlWriter.

        if (prefixes != null) {
            for (int i = 0; i < prefixes.size(); i++) {
                writer.setPrefix (getNamespacePrefix (i), getNamespaceUri (i));


        int len = getAttributeCount();

        for (int i = 0; i < len; i++) {


        writer.endTag(getNamespace (), getName ());
