有什么方法可以读取.docx文件，包括使用python-docx自动编号 [英] Is there any way to read .docx file include auto numbering using python-docx

问题描述

问题陈述:从.docx文件中提取节，包括自动编号.

Problem statement: Extract sections from .docx file including autonumbering.

我尝试使用python-docx从.docx文件中提取文本，但它不包括自动编号功能.

I tried python-docx to extract text from .docx file but it excludes the autonumbering.

from docx import Document

document = Document("wadali.docx")


def iter_items(paragraphs):
    for paragraph in document.paragraphs:
        if paragraph.style.name.startswith('Agt'):
            yield paragraph
        if paragraph.style.name.startswith('TOC'):
            yield paragraph
        if paragraph.style.name.startswith('Heading'):
            yield paragraph
        if paragraph.style.name.startswith('Title'):
            yield paragraph
        if paragraph.style.name.startswith('Heading'):
            yield paragraph
        if paragraph.style.name.startswith('Table Normal'):
            yield paragraph
        if paragraph.style.name.startswith('List'):
            yield paragraph


for item in iter_items(document.paragraphs):
    print item.text

推荐答案

似乎当前 python-docx v0.8不完全支持编号.您需要进行一些黑客入侵.

It appears that currently python-docx v0.8 does not fully support numbering. You need to do some hacking.

首先，对于演示而言，要迭代文档段落，您需要编写自己的迭代器.这是一些功能:

First, for the demo, to iterate the document paragraphs, you need to write your own iterator. Here is something functional:

import docx.document
import docx.oxml.table
import docx.oxml.text.paragraph
import docx.table
import docx.text.paragraph


def iter_paragraphs(parent, recursive=True):
    """
    Yield each paragraph and table child within *parent*, in document order.
    Each returned value is an instance of Paragraph. *parent*
    would most commonly be a reference to a main Document object, but
    also works for a _Cell object, which itself can contain paragraphs and tables.
    """
    if isinstance(parent, docx.document.Document):
        parent_elm = parent.element.body
    elif isinstance(parent, docx.table._Cell):
        parent_elm = parent._tc
    else:
        raise TypeError(repr(type(parent)))

    for child in parent_elm.iterchildren():
        if isinstance(child, docx.oxml.text.paragraph.CT_P):
            yield docx.text.paragraph.Paragraph(child, parent)
        elif isinstance(child, docx.oxml.table.CT_Tbl):
            if recursive:
                table = docx.table.Table(child, parent)
                for row in table.rows:
                    for cell in row.cells:
                        for child_paragraph in iter_paragraphs(cell):
                            yield child_paragraph

您可以使用它来查找所有文档段落，包括表格单元格中的段落.

You can use it to find all document paragraphs including paragraphs in table cells.

例如:

import docx

document = docx.Document("sample.docx")
for paragraph in iter_paragraphs(document):
    print(paragraph.text)

要访问编号属性，您需要搜索受保护"成员 paragraph._p.pPr.numPr ，这是 docx.oxml.numbering.CT_NumPr 对象:

To access the numbering property, you need to search in the "protected" members paragraph._p.pPr.numPr, which is a docx.oxml.numbering.CT_NumPr object:

for paragraph in iter_paragraphs(document):
    num_pr = paragraph._p.pPr.numPr
    if num_pr is not None:
        print(num_pr)  # type: docx.oxml.numbering.CT_NumPr

请注意，此对象是从 numbering.xml 文件(在docx内部)提取的(如果存在).

Note that this object is extracted from the numbering.xml file (inside the docx), if it exists.

要访问它，您需要像打包文件一样读取docx文件.例如:

To access it, you need to read your docx file like a package. For instance:

import docx.package
import docx.parts.document
import docx.parts.numbering

package = docx.package.Package.open("sample.docx")

main_document_part = package.main_document_part
assert isinstance(main_document_part, docx.parts.document.DocumentPart)

numbering_part = main_document_part.numbering_part
assert isinstance(numbering_part, docx.parts.numbering.NumberingPart)

ct_numbering = numbering_part._element
print(ct_numbering)  # CT_Numbering
for num in ct_numbering.num_lst:
    print(num)  # CT_Num
    print(num.abstractNumId)  # CT_DecimalNumber
