Class | Builder::XmlEvents
In: | lib/active_support/vendor/builder-2.1.2/builder/xmlevents.rb
Parent: | XmlMarkup

Create a series of SAX-like XML events (e.g. start_tag, end_tag) from the markup code. XmlEvent objects are used in a way similar to XmlMarkup objects, except that a series of events are generated and passed to a handler rather than generating character-based markup.

Usage:

      xe = Builder::XmlEvents.new(hander)
      xe.title("HI")    # Sends start_tag/end_tag/text messages to the handler.

Indentation may also be selected by providing value for the indentation size and initial indentation level.

      xe = Builder::XmlEvents.new(handler, indent_size, initial_indent_level)

## XML Event Handler

The handler object must expect the following events.

`start_tag(tag, attrs)`
  Announces that a new tag has been found. `tag` is the name of the tag and `attrs` is a hash of attributes for the tag.
`end_tag(tag)`
  Announces that an end tag for `tag` has been found.
`text(text)`
  Announces that a string of characters (`text`) has been found. A series of characters may be broken up into more than one `text` call, so the client cannot assume that a single callback contains all the text data.

### Methods

_end_tag _start_tag text!

### Public Instance methods

_end_tag(sym)
_start_tag(sym, attrs, end_too=false)
text!(text)
