У меня есть XML, структурированный так:

Я хочу объединить смежные символы, имеющие одинаковый тег text с тем же атрибутом size, но только для каждого new_line block.

Мой ожидаемый результат будет: 

  <pages>
      <page id="1" bbox="0.000,0.000,462.047,680.315" rotate="0">
        <textbox id="0" bbox="191.745,592.218,249.042,603.5>

</new_line>
</textline>
</textbox>
</page>
</pages>

Но вместо этого я получаю это: 

  <pages>
      <page id="1" bbox="0.000,0.000,462.047,680.315" rotate="0">
        <textbox id="0" bbox="191.745,592.218,249.042,603.5>

          <text font="NUMPTY+ImprintMTnum" bbox="324.480,553.628,327.384,566.110" colourspace="DeviceGray" ncolour="0" size="12.482">sventura] </text>

</new_line>
</textline>

    </pages>

Мой код такой: 

import lxml.etree as etree

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

# Iterate over //newline block
for new_line_block in tree.xpath('//new_line'):
    # Find all "test" element in the new_line block
    list_text_elts = new_line_block.xpath('//text')

    # Iterate over all of them with the current and previous ones
    for previous_text, current_text in zip(list_text_elts[:-1], list_text_elts[1:]):
        # Get size elements
        prev_size = previous_text.attrib.get('size')
        curr_size = current_text.attrib.get('size')
        # If they are equals and not both null
        if curr_size == prev_size and curr_size is not None:
            # Get current and previous text
            pt = previous_text.text if previous_text.text is not None else ""
            ct = current_text.text if current_text.text is not None else ""
            # Add them to current element
            current_text.text = pt + ct
            # Remove preivous element
            previous_text.getparent().remove(previous_text)


newtree = etree.tostring(root, encoding='utf-8', pretty_print=True)
#newtree = newtree.decode("utf-8")
#print(newtree)
with open("output2.xml", "wb") as f:
    f.write(newtree)

Что я могу сделать, чтобы решить мою проблему?
