+## Формулировка задания
+
+Дан XML-файл следующего содержания:
+
+```xml
+
+
+
+ J. Smith
+ Steve Jobs
+ 2024
+
+
+ J. Smith
+ Steve Jobs
+ 2022
+
+
+ A. Turing
+ Computing Machinery and Intelligence
+ 1950
+
+
+ G. Orwell
+ 1984
+ 1949
+
+
+```
+
+Необходимо спарсить его в класс, и реализовать консольный интерфейс для работы с ним. Доступные команды:
+- Вывод всех книг
+- Поиск книг по имени автора или году издания
+- Вывод в консоль пар `автор + название` с возможностью сортировать как по автору, так и по названию
+- Поиск книг по диапозону дат
+
+Операции для поиска данных реализовать с помощью Streaming API.
+
+## Запуск через Gradle

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
