- # 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.
