有什么方法可以读取 .docx 文件包括使用 python-docx 的自动编号

Question

问题陈述：从 .docx 文件中提取部分，包括自动编号。

我试过 python-docx 从 .docx 文件中提取文本，但它不包括自动编号。

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

看来目前python-docx v0.8 还没有完全支持编号。你需要做一些黑客攻击。

首先，为了演示，要迭代文档段落，您需要编写自己的迭代器。这是一些实用的东西：

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 table 个单元格中的段落。

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，您需要在 "protected" 成员 paragraph._p.pPr.numPr 中搜索，这是一个 docx.oxml.numbering.CT_NumPr 对象：

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）中提取的（如果存在）。

要访问它，您需要像阅读包一样阅读您的 docx 文件。例如：

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

Office Open XMl 文档中提供了更多信息。

有一个包 docx2python 以更简单的方式执行此操作：pypi。org/project/docx2python/

以下代码：

from docx2python import docx2python
document = docx2python("C:/input/MyDoc.docx")
print(document.body)

生成一个列表，其中包含以可解析的方式包含项目符号列表的内容。
