Performs a grep (global-regular-expression-print) search of files in OpenXML format, which is to say inside ZIP files. See the command-line help for details.

Notes:

  • use the vbindiff tool to show how two binary files differ.
cardinal_pythonlib.openxml.grep_in_openxml.main() → None[source]

Command-line handler for the grep_in_openxml tool. Use the --help option for help.

cardinal_pythonlib.openxml.grep_in_openxml.parse_zip(zipfilename: str, regex: Pattern[AnyStr], invert_match: bool, files_with_matches: bool, files_without_match: bool, grep_inner_file_name: bool, show_inner_file: bool) → None[source]

Implement a “grep within an OpenXML file” for a single OpenXML file, which is by definition a .zip file.

Parameters:
  • zipfilename – name of the OpenXML (zip) file
  • regex – regular expression to match
  • invert_match – find files that do NOT match, instead of ones that do?
  • files_with_matches – show filenames of files with a match?
  • files_without_match – show filenames of files with no match?
  • grep_inner_file_name – search the names of “inner” files, rather than their contents?
  • show_inner_file – show the names of the “inner” files, not just the “outer” (OpenXML) file?
cardinal_pythonlib.openxml.grep_in_openxml.report_hit_filename(zipfilename: str, contentsfilename: str, show_inner_file: bool) → None[source]

For “hits”: prints either the .zip filename, or the .zip filename and the inner filename.

Parameters:
  • zipfilename – filename of the .zip file
  • contentsfilename – filename of the inner file
  • show_inner_file – if True, show both; if False, show just the .zip filename

Returns:

cardinal_pythonlib.openxml.grep_in_openxml.report_line(zipfilename: str, contentsfilename: str, line: str, show_inner_file: bool) → None[source]

Prints a line from a file, with the .zip filename and optionally also the inner filename.

Parameters:
  • zipfilename – filename of the .zip file
  • contentsfilename – filename of the inner file
  • line – the line from the inner file
  • show_inner_file – if True, show both filenames; if False, show just the .zip filename
cardinal_pythonlib.openxml.grep_in_openxml.report_miss_filename(zipfilename: str) → None[source]

For “misses”: prints the zip filename.
