changelog.sh

#!/usr/bin/env sh

# skip first few lines in file (xml setup)
# replace explicit new lines in strings with nothing (all newlines are on own line)
# remove leading spaces
# read up to first blank line
tail -n +6 app/src/main/res/values/changelog.xml | \
    sed s'|\\n||g'  | \

extract-release-notes-from-android-changelog-resource-string.md

Shell script using only tail and sed to extract lines from an Android xml string resource file

tail -n +6 app/src/main/res/values/changelog.xml | \
    sed s'|\\n||g'  | \
    sed s'|^\ *||' | \
    sed -e '/^$/,$d'

This parses a changelog.xml file, which is used in-app to display release history. The xml file has the usual resource setup, followed by the version names and notes below them:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="changelog">
        \n
        <A version number, ignored by the script above>:\n
        - A line to describe something in this version\n
        \n
        <another version>:\n
        - Things to\n
        - describe this\n
        - release\n
        \n
        ...

This outputs:

- A line to describe something in this version
