Create a new StartElement.

Usage

From source file:Main.java

/**
 * Constructs a new StartElement that merges the attributes and namespaces
 * found in the specified StartElement, with the provided attributes. The
 * returned StartElement will contain all the attributes and namespaces of
 * the original, plus those defined in the map.
 * /*from   ww  w . j av  a  2  s  .  c  o  m*/
 * @param tag The original StartElement
 * @param attrs An iterator of Atributes to add to the element.
 * @return A new StartElement that contains all the original attributes and
 *         namespaces, plus the provided attributes.
