При вставке родительского элемента в XML его родительский элемент не сохраняется (Python)

Question

У меня есть XML документ, структурированный так:

<pages>
  <page id="1" bbox="0.000,0.000,462.047,680.315" rotate="0">
    <textbox id="0" bbox="191.745,592.218,249.042,603.578">
      <textline bbox="191.745,592.218,249.042,603.578">
<text bbox="191.745,592.218,249.042,603.578">a
</text>
<text bbox="191.745,592.218,249.042,603.578">b
</text>
<textline>
</textbox>
<textbox id="1" bbox="0.000,0.000,462.047,680.315" rotate="0">
<textline id="1" bbox="0.000,0.000,462.047,680.315" rotate="0">
<text bbox="0.000,0.000,462.047,680.315">c
</text>
</textbox>
</textline

В этом документе, если бы было определенное расстояние между значением атрибута одного text элемента и его предшествующего брата, я бы Откройте тег new_line и закройте его, когда возникла необходимость открыть новый.

Код работает, но с ним есть проблема, поскольку родительский элемент textbox не сохраняется должным образом.

Мой код такой:

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)

По сути, XML принимает предыдущее строка при вставке new_line родительского тега.

      </new_line>

В основном он начинается new_line чуть позже textbox, а не сразу после textbox.

Ссылка на полный вывод, который я получаю: ссылка

Answer 1

Я вижу две точки.

• Во-первых, все элементы <textline> можно удалить с помощью strip_tags. В этом обсуждении объясняется, как работает функция.

• А затем оберните поиск new_line во всех <textbox> элементах, используя iter.

Полный код :

import lxml.etree as etree

parser = etree.XMLParser(remove_blank_text=True)
tree = etree.parse('data.xml', parser)

# 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

# Remove all 'textline' elements
etree.strip_tags(tree, 'textline')

# Search for all text "textbox" elements
for textbox in tree.xpath('//textbox'):
    new_line = etree.Element("new_line")
    previous_bb = None

    # From a given textbox element, iterate over all the "text" elements
    for x in textbox.iter("text"):
        # Get current bb valu
        bb = getBBoxFirstValue(x)
        # Check current and past values aren't empty
        if bb is not None and previous_bb is not None and (bb - previous_bb) > 10:
            # Inserte newline into parent tag
            x.getparent().insert(x.getparent().index(x), new_line)

            # A new "new_line" element is created
            new_line = etree.Element("new_line")

        # Append current element is new_line tag
        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
    textbox.append(new_line)


tree.write("output.xml", pretty_print=True)

Надеюсь, это поможет!
