XSLT типография
Разделите большое количество текста на произвольное количество равных частей.
Мне, наверное, уже надоели их глупые вопросы, но у меня есть еще один вопрос.
У меня большой кусок текста

На выходе мне нужно разделить текст на "n" равными частями, чтобы в этих частях было примерно одинаковое количество текста. Затем эти части располагаются в столбцах, и необходимость в этих столбцах выглядит примерно одинаковой высоты. Другое условие: теги можно разбить (я имею в виду, что если тег "p" содержит много текста, его можно разделить на две части, чтобы перенести в другой столбец). Я думаю, что это монументальное задание, буду благодарен за любую помощь.
Я понимаю, что XSLT не является инструментом типографики. Но возможно ли разделить текст на части с одинаковым количеством символов в каждой части?

Возможно выравнивание текста с помощью XSLT (я делал это много лет назад). Вот небольшой пример, который вы можете использовать в качестве основы для выполнения вашей полной задачи:
Это преобразование:
<xsl:stylesheet version="1.0"

когда выполняется над этим документом XML (это оригинальный документ, который использовался тогда - этот текст CNN может быть прослежен до 2003 или 2002):
<text>
Dec. 13 — As always for a presidential inaugural, security and surveillance were
extremely tight in Washington, DC, last January. But as George W. Bush prepared to
take the oath of office, security planners installed an extra layer of protection: a
prototype software system to detect a biological attack. The U.S. Department of
Defense, together with regional health and emergency-planning agencies, distributed
a special patient-query sheet to military clinics, civilian hospitals and even aid
stations along the parade route and at the inaugural balls. Software quickly
analyzed complaints of seven key symptoms — from rashes to sore throats — for
patterns that might indicate the early stages of a bio-attack. There was a brief
scare: the system noticed a surge in flulike symptoms at military clinics.
Thankfully, tests confirmed it was just that — the flu.

правильно выполняет выравнивание каждой строки до нужной ширины не более 64 В результате получается:
