# The input document first is parsed into a list of strings. Each string
# represents one of the following:
# - text node
# - processing instruction (the XML declaration is treated as a PI)
# - comment
# - CDATA section
# - DOCTYPE declaration
# - element tag (either <abc>, </abc>, or <abc/>), *including attributes*
# Entities are left untouched. They appear in their original form as part
# of the text node in which they occur.
# The list of strings then is converted to a hierarchical structure.
# The document top level is represented by a reference to a list.
# Each list element is a reference to a node -- a hash that has "type"
# and "content" key/value pairs. The "type" key indicates the node
# type and has one of the following values:
# "text" - text node
# "pi" - processing instruction node
# "comment" - comment node
# "CDATA" - CDATA section node
# "DOCTYPE" - DOCTYPE node
# "elt" - element node
# (For purposes of this program, it's really only necessary to have "text",
# "elt", and "other". The types other than "text" and "elt" currently are
# all treated the same way.)
# For all but element nodes, the "content" value is the text of the node.
# For element nodes, the "content" hash is a reference to a list of
# nodes for the element's children. In addition, an element node has
# three additional key/value pairs:
# - The "name" value is the tag name within the opening tag, minus angle
# brackets or attributes.
# - The "open_tag" value is the full opening tag, which may also be the
# closing tag.
# - The "close_tag" value depends on the opening tag. If the open tag is
# "<abc>", the close tag is "</abc>". If the open tag is "<abc/>", the
# close tag is the empty string.
# If the tree structure is converted back into a string with
# tree_stringify(), the result can be compared to the input file
# as a regression test. The string should be identical to the original
# input document.

Usage: $prog_name [options] xml-file
Options:
--help, -h
Print this message
--backup suffix -b suffix
Back up the input document, adding suffix to the input
filename to create the backup filename.
--canonized-output
Proceed only as far as the document canonization stage,
printing the result.
--check-parser
Parse the document into tokens and verify that their
concatenation is identical to the original input document.
This option suppresses further document processing.
--config-file file_name, -f file_name
Specify the configuration filename. If no file is named,
xmlformat uses the file named by the environment variable
XMLFORMAT_CONF, if it exists, or ./xmlformat.conf, if it
exists. Otherwise, xmlformat uses built-in formatting
options.
--in-place, -i
Format the document in place, replacing the contents of
the input file with the reformatted document. (It's a
good idea to use --backup along with this option.)
--show-config
Show configuration options after reading configuration
file. This option suppresses document processing.
--show-unconfigured-elements
Show elements that are used in the document but for
which no options were specified in the configuration
file. This option suppresses document output.
--verbose, -v
Be verbose about processing stages.
--version, -V
Show version information and exit.
