\alias{xmlEventHandler}
\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}{}
