\title{Default handlers for the SAX-style event XML parser}
\description{
 This is a function that returns a closure instance 
 containing the default handlers for use with 
 \code{\link{xmlEventParse}} for parsing XML documents
 via the SAX-style parsing.
}
\usage{
xmlEventHandler()
}
\details{
 These handlers simply build up the DOM tree and thus 
 perform the same job as \code{xmlTreeParse}.
 It is here more as an example, reference and a base
 that users can extend.
}
\value{
The return value is a list of functions
which are used as callbacks by the internal XML parser
when it encounters certain XML elements/structures.
These include items such as the start of an element,
end of an element, processing instruction, 
text node, comment, entity references and definitions, etc.

  \item{startElement}{}
  \item{endElement}{}
  \item{processingInstruction}{}
  \item{text}{}
  \item{comment}{}
  \item{externalEntity}{}
  \item{entityDeclaration}{}
  \item{cdata}{}
  \item{dom}{}
