How to return the heading number

Hi

I have managed to return the heading text in a given filename (thank you to the great experts at Stack Overflow) however I cannot return the heading number. Refer to code below. Is there a way to print/return the heading number (list numbering value not heading level).

Thanks

import docx

doc=docx.Document('filename.docx')

def iter_heading(paragraphs):
    for paragraph in paragraphs:
        if paragraph.style.name('Heading 1'):
            yield paragraph

for heading in iter_heading(doc.paragraphs):
    print(heading.text)

a solution, call addHeaderNumbering just before saving the document

def iter_heading(paragraphs):
    for paragraph in paragraphs:
        isItHeading=re.match('Heading ([1-9])',paragraph.style.name)
        if isItHeading:
            yield int(isItHeading.groups()[0]),paragraph

def addHeaderNumbering(document):
    hNums=[0,0,0,0,0]
    for index,hx in iter_heading(document.paragraphs):
        # ---put zeroes below---
        for i in range(index+1,5):
            hNums[i]=0
        # ---increment this---
        hNums[index]+=1
        # ---prepare the string---
        hStr=""
        for i in range(1,index+1):
            hStr+="%d."%hNums[i]
        # ---add the numbering---
        hx.text=hStr+" "+hx.text

so i’ve looked into this several times. The issue appears to be that the underlying xml is very convoluted in how apps like Word generate actual heading numbers.

Here’s a primer: http://officeopenxml.com/WPnumbering.php

it seems implented in javascript’s docx here: https://docx.js.org/#/usage/numbering

Regardless, it’s pretty difficult to parse since it refers to document level metadata, which tracks numbering not as shown but as calculated through whatever is happening in the document.

While this would be a great feature, I can see already someone would need to spend quite a bit of energy getting it to work.
