18.35 XML YAML JSON Conversion
20220912
Use the yq command to convert between YAML, JSON, and XML. The source code is available from command from https://github.com/mikefarah/yq with the documentation at https://mikefarah.gitbook.io/yq/.
To convert XML to YAML use --input-format string= (-p=) to specify
xml as the input format and --output-format string= (-o=) to
specify the output format as json
See Section 18.36 for details of the yq command.
A more sophisticated example extracts iradio entries from
RhythmBox’s
~/.local/share/rhythmbox/rhythmdb.xml file to convert to
json. Then use radiotray-ng’s Bookmark Editor under
Preferences to import those JSON entries into the file
~/.config/radiotray-ng/bookmarks.json (or use a text editor to do
so).
We can extract all of the iradio entries from the RhythmBox database with:
cat ~/.local/share/rhythmbox/rhythmdb.xml |
yq -p=xml -o=json '.rhythmdb.entry[] | select(.+type == "iradio") | {"name":.title, "url": .location}'The following will extract entries which have a specific genre into a json format consisting of name and url as required by radiotray.
cat ~/.local/share/rhythmbox/rhythmdb.xml |
yq -p=xml -o=json '.rhythmdb.entry[] | select(.+type == "iradio") | select(.genre == "Guitar") | {"name":.title, "url": .location}'Some manual processing still required, including commas between entries and grouping into the genre/group. Work in progress to get closer to what is required for radiotray.
