# Test the 'maint print xml-tdesc' command. This file picks up every
# XML file matching the pattern maint-xml-dump-*.xml (in the same
# directory as this script) and passes each in turn to the command
# 'maint print xml-tdesc'.
#
# The expected output is generated by parsing the input XML file. The
# rules for changing an XML file into the expected output are:
#
# 1. Blank lines, and lines starting with a comment are stripped from
# the expected output.
#
# 2. The <?xml ... ?> and <!DOCTYPE ...> entities are optional,
# suitable defaults will be added if these lines are missing from
# the input file.
#
# 3. A trailing comment on a line will replace the expected output for
# that line but with the indentation of the line preserved. So
# this (The '|' marks the start of the line):
# | <reg name="r1" bitsize="32"/> <!-- <reg name="r1" bitsize="32" type="int" regnum="0"/> -->
# Will actually look for the following output:
# | <reg name="r1" bitsize="32" type="int" regnum="0"/>
#
# 4. Indentation of lines will be preserved so your input file needs
# to follow the expected indentation.
