# Description Add `xaccess`,`xupdate` and `xinsert` scripts to standard library. They allow accessing and manipulating data in new xml format https://github.com/nushell/nushell/pull/7947 with relative ease. Access some data in nushell xml structure:  Update attributes of xml tags matching a path:  # User-Facing Changes New commands `std xaccess`, `std xupdate` and `std xinsert` # Tests + Formatting Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass > **Note** > from `nushell` you can also use the `toolkit` as follows > ```bash > use toolkit.nu # or use an `env_change` hook to activate it automatically > toolkit check pr > ``` # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date.
