Removing metadata Leave feedback

Not all metadata properties extracted from a file are marked with tags. Some file formats and metadata standards allow fully custom properties that can’t be tagged by the library, because their purpose is not clearly defined in the corresponding specification. In such cases you can use the property name (or any other attribute) to locate and remove it. The following example demonstrates an advanced removal scenario.

1. Load a file to modify
2. Pass a search predicate to the remove_properties method
3. Check the number of properties that were actually removed
4. Save the changes

from groupdocs.metadata import Metadata
from groupdocs.metadata.tagging import Tags


def removing_metadata():
    with Metadata("input.docx") as metadata:
        # Remove every property whose tags fall into the "content" category
        affected = metadata.remove_properties(
            lambda p: any(tag.category == Tags.content for tag in p.tags)
        )
        print(f"Affected properties: {affected}")
        metadata.save("output.docx")


if __name__ == "__main__":
    removing_metadata()
