# Warning!
|

#
|

# This module is tightly bound to the implementation details of the

# minidom DOM and can't be used with other DOM implementations. This
|
||||
# is due, in part, to a lack of appropriate methods in the DOM (there is
|

# no way to create Entity and Notation nodes via the DOM Level 2
|

# interface), and for performance. The latter is the cause of some fairly

# cryptic code.
|

#
|
||||
# Performance hacks:
|
||||
#
|
||||
# - .character_data_handler() has an extra case in which continuing
|
||||
# data is appended to an existing Text node; this can be a
|
||||
# speedup since pyexpat can break up character data into multiple
|
||||
# callbacks even though we set the buffer_text attribute on the
|
||||
# parser. This also gives us the advantage that we don't need a
|
||||
# separate normalization pass.
|
||||
#
|
||||
# - Determining that a node exists is done using an identity comparison
|
||||
# with None rather than a truth test; this avoids searching for and
|
||||
# calling any methods on the node object if it exists. (A rather
|
||||
# nice speedup is achieved this way as well!)
