Как вставить родительский тег при условии XML Python?

Question

У меня есть XML, структурированный так:

То есть преобразование этой части PDF (выделено на скриншоте):

У меня есть код, который добавляет новую строку каждый раз, когда появляется новый текстовый сегмент (большой интервал между словами, изображенный на рисунке выше, в нашем случае между "Rodri go" и " 1 "). Я делаю это, используя атрибут "bbox" XML. Мой код работает таким образом, но проблема в том, что он не учитывает дефисы, поскольку они означают, что это одно и то же слово. Поэтому мне нужно, чтобы «mi-seria» была вместе внутри тега newline, а следующий символ новой строки начинается с «della». Если дефиса нет, должен начинаться перевод строки.

У меня есть обходной путь, который заставляет что-то работать, но мне нужно что-то более точное. Пока что мой вывод подходит для сегмента:

Но у меня нет кода, который говорит: «вставьте новую строку, только если расстояние <0 (я имею в виду, отрицательное число) и там не дефис, в противном случае не ". </p>

Мой код до сих пор:

import lxml.etree as etree

parser = etree.XMLParser(remove_blank_text=True)
tree = etree.parse('fe3.xml', parser)
root = tree.getroot()

# Get the first BBox value as float
# Return null if not found
def getBBoxFirstValue(line):
    if line is not None:
        bb = line.attrib.get('bbox')
        if bb is not None:
            try:
                return float(bb.split(",")[0])
            except ValueError:
                pass
    return None

new_line        = None
previous_bb     = None

for x in tree.xpath('//text'):
    # Get current bb value
    bb = getBBoxFirstValue(x)
    # Check current and past values aren't empty
    if bb is not None and previous_bb is not None:
        #print(bb, previous_bb, (bb-previous_bb))
        #print(abs(bb-previous_bb))
        # If distance with preview bb > 10
        if (bb - previous_bb) > 20 or (bb - previous_bb) < -1000:
            # If new_line isn't empty: it's inserted into parent tag at position of current tag

            if new_line is not None:
                x.getparent().insert(x.getparent().index(x), new_line)
            # A new "new_line" element is created
            new_line = etree.Element("new_line")

        # If the new line isn't not (e.g. one distance > 10 has been already found)
        if new_line is not None:
            new_line.append(x)

    # Keep latest non empty BBox 1st value
    if bb is not None:
        previous_bb = bb

# Add last new_line element if not null
if new_line is not None:
    tree.xpath('//text')[-1].getparent().append(new_line)


newtree = etree.tostring(root, encoding='utf-8', pretty_print=True)
#newtree = newtree.decode("UTF-8")
print(newtree)
with open("output.xml", "wb") as f:
    f.write(newtree)

Подводя итог, как я могу сделать мой код лучше, чтобы я мог вставить newline тег, когда указано определенное расстояние, но если есть дефис, я не разделяю слова, а если дефиса нет, я разделяю слова, открывая новый тег newline ?
