append(value)

find(content_type)

openpyxl.packaging.relationship.get_dependents(archive, filename)

Relative paths are relative to parent object

openpyxl.packaging.relationship.get_rel(archive, deps, id=None, cls=None)

Get related object based on id or rel_type

openpyxl.packaging.relationship.get_rels_path(path)

Convert relative path to absolutes that can be loaded from a zip archive. The path to be passed in is that of containing object (workbook, worksheet, etc.)

openpyxl.packaging.relationship.tostring(element, *, encoding='utf-8', method=None, short_empty_elements=True)
