This namespace will be the same as 325N/A * the one that would be returned by 325N/A * <code>{@link #getNamespaceURI(String)}</code> if it were given 325N/A * <code>prefix</code> as it's parameter. 325N/A * @exception SOAPException if the <code>QName</code> cannot be created. 325N/A * Returns the name of this <code>SOAPElement</code> object. 325N/A * @return a <code>Name</code> object with the name of this 325N/A * <code>SOAPElement</code> object 325N/A * Returns the qname of this <code>SOAPElement</code> object. 325N/A * @return a <code>QName</code> object with the qname of this 325N/A * <code>SOAPElement</code> object 325N/A * @see SOAPElement#getElementName() 325N/A * Changes the name of this <code>Element</code> to <code>newName</code> if 325N/A * possible.

Any attempt to do 325N/A * so will result in a SOAPException being thrown. 325N/A * Callers should not rely on the element instance being renamed as is. 325N/A * Implementations could end up copying the content of the 325N/A * <code>SOAPElement</code> to a renamed instance. 325N/A * @param newName the new name for the <code>Element</code>. 325N/A * @exception SOAPException if changing the name of this <code>Element</code> 325N/A * @return The renamed Node 325N/A * Removes the attribute with the specified name. 325N/A * @param name the <code>Name</code> object with the name of the 325N/A * attribute to be removed 325N/A * @return <code>true</code> if the attribute was 325N/A * removed successfully; <code>false</code> if it was not 325N/A * Removes the attribute with the specified qname. 325N/A * @param qname the <code>QName</code> object with the qname of the 325N/A * attribute to be removed 325N/A * @return <code>true</code> if the attribute was 325N/A * removed successfully; <code>false</code> if it was not 325N/A * @see SOAPElement#removeAttribute(Name) 325N/A * Removes the namespace declaration corresponding to the given prefix. 325N/A * @param prefix a <code>String</code> giving the prefix for which 325N/A * @return <code>true</code> if the namespace declaration was 325N/A * removed successfully; <code>false</code> if it was not 325N/A * Returns an <code>Iterator</code> over all the immediate child 325N/A * {@link Node}s of this element. This includes <code>javax.xml.soap.Text</code> 325N/A * objects as well as <code>SOAPElement</code> objects. 325N/A * Calling this method may cause child <code>Element</code>, 325N/A * <code>SOAPElement</code> and <code>org.w3c.dom.Text</code> nodes to be 325N/A * replaced by <code>SOAPElement</code>, <code>SOAPHeaderElement</code>, 325N/A * <code>SOAPBodyElement</code> or <code>javax.xml.soap.Text</code> nodes as 325N/A * appropriate for the type of this parent node.
