如何在Linux上使用python更新docx文件中的目录? [英] How to update table of contents in docx-file with python on linux?

问题描述

我在docx文件中的更新目录中遇到了问题，该目录由Linux上的 python-docx 生成.通常，创建目录并不困难(感谢此答案 https://stackoverflow.com/a/48622274/9472173 和此线程 https://github.com/python-openxml/python-docx/issues/36 )

I've got a problem with updating table of contents in docx-file, generated by python-docx on Linux. Generally, it is not difficult to create TOC (Thanks for this answer https://stackoverflow.com/a/48622274/9472173 and this thread https://github.com/python-openxml/python-docx/issues/36)

from docx.oxml.ns import qn
from docx.oxml import OxmlElement

paragraph = self.document.add_paragraph()
run = paragraph.add_run()
fldChar = OxmlElement('w:fldChar')  # creates a new element
fldChar.set(qn('w:fldCharType'), 'begin')  # sets attribute on element
instrText = OxmlElement('w:instrText')
instrText.set(qn('xml:space'), 'preserve')  # sets attribute on element
instrText.text = 'TOC \o "1-3" \h \z \u'   # change 1-3 depending on heading levels you need

fldChar2 = OxmlElement('w:fldChar')
fldChar2.set(qn('w:fldCharType'), 'separate')
fldChar3 = OxmlElement('w:t')
fldChar3.text = "Right-click to update field."
fldChar2.append(fldChar3)

fldChar4 = OxmlElement('w:fldChar')
fldChar4.set(qn('w:fldCharType'), 'end')

r_element = run._r
r_element.append(fldChar)
r_element.append(instrText)
r_element.append(fldChar2)
r_element.append(fldChar4)
p_element = paragraph._p

但是稍后要使TOC可见，则需要更新字段.提及的波纹管解决方案涉及手动进行更新(右键单击TOC提示，然后选择更新字段").对于自动更新，我发现了以下使用Word应用程序模拟的解决方案(由于此答案 https://stackoverflow.com/a/34818909/9472173 )

But later to make TOC visible it requires to update fields. Mentioned bellow solution involves update it manually (right-click on TOC hint and choose 'update fields'). For the automatic updating, I've found the following solution with word application simulation (thanks to this answer https://stackoverflow.com/a/34818909/9472173)

import win32com.client
import inspect, os

def update_toc(docx_file):
    word = win32com.client.DispatchEx("Word.Application")
    doc = word.Documents.Open(docx_file)
    doc.TablesOfContents(1).Update()
    doc.Close(SaveChanges=True)
    word.Quit()

def main():
    script_dir = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))
    file_name = 'doc_with_toc.docx'
    file_path = os.path.join(script_dir, file_name)
    update_toc(file_path)

if __name__ == "__main__":
    main()

它在Windows上很有效，但显然在Linux上不行.让某人对如何在Linux上提供相同功能有任何想法.我唯一的建议是在每个标题中都使用本地URL(锚)，但是我不确定 python-docx 是否可能，而且我对这些不太满意openxml 功能.我将非常感谢您的帮助.

It pretty works on Windows, but obviously not on Linux. Have someone any ideas about how to provide the same functionality on Linux. The only one suggestion I have is to use local URLs (anchors) to every heading, but I am not sure is it possible with python-docx, also I'm not very strong with these openxml features. I will very appreciate any help.

推荐答案

我从此[Github Issue] [1]中找到了一个解决方案.它可以在ubuntu上运行.

I found a solution from this [Github Issue][1]. It work on ubuntu.

def set_updatefields_true(docx_path):
    namespace = "{http://schemas.openxmlformats.org/wordprocessingml/2006/main}"
    doc = Document(docx_path)
    # add child to doc.settings element
    element_updatefields = lxml.etree.SubElement(
        doc.settings.element, f"{namespace}updateFields"
    )
    element_updatefields.set(f"{namespace}val", "true")
    doc.save(docx_path)## Heading ##
