xmlEventHandler {XML} | R Documentation

## 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 `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 `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.

`startElement` |
`endElement` |
`processingInstruction` |
`text` |
`comment` |
`externalEntity` |
`entityDeclaration` |
`cdata` |
`dom` |
