Parsing Word documents with Python

If you ever had a need to programmatically examine the text in a Microsoft Word document, getting the text out in the first place can be challenging. Sure, you can manually save your document to a plain text file that’s much easier to process, but if you have multiple documents to examine, that can be painful.

Recently I had such a need and found this Toward Data Science article quite helpful. But let’s take the challenge a little further: suppose you had a document with multiple sections and need to pull the text from specific sections.

Let’s suppose I need to pull just the text from the “sub-sections”. In my example, I have three sub-sections: Sub-Section 1, Sub-Section 2, and Sub-Section 3. In my Word document, I’ve styled these headers as “Heading 2” text. Here’s how I went about pull out the text for each of these sections.

Step 1: Import your packages

For my needs, I only need to import zipfile and ElementTree, which is nice as I didn’t need to install any third party packages:

import zipfile import xml.etree.ElementTree as ET

Step 2: Parse the document XML

doc = zipfile.ZipFile('./data/test.docx').read('word/document.xml') root = ET.fromstring(doc)

Step 3: Explore the XML for the sections and text you want

You’ll spend most of your time here, trying to figure out what elements hold the contents in which you are interested. The XML of Microsoft documents follows the WordprocessingML standard, which can be quite complicated. I spent a lot of time manually reviewing my XML looking for the elements I needed. You can write out the XML like so:

Step 4: Find all the paragraphs

To solve my problem, I first decided to pull together a collection of all the paragraphs in the document so that I could later iterate across them and make decisions. To make that work a little easier, I also declared a namespace object used by Microsoft’s WordprocessingML standard:

# Microsoft's XML makes heavy use of XML namespaces; thus, we'll need to reference that in our code ns = body = root.find('w:body', ns) # find the XML "body" tag p_sections = body.findall('w:p', ns) # under the body tag, find all the paragraph sections

It can be helpful to actually see the text in each of these sections. Through researching Microsoft’s XML standard, I know that document text is usually contained in “t” elements. So, if I write an XPath query to find all the “t” elements within a given section, I can join the text of all those elements together to get the full text of the paragraph. This code does that:

for p in p_sections: text_elems = p.findall('.//w:t', ns) print(''.join([t.text for t in text_elems])) print()

Step 5: Find all the “Heading 2” sections

Now, let’s iterate through each paragraph section and see if we can figure out which sections have been styled with “Heading 2”. If we can find those Heading 2 sections, we’ll then know that the subsequent text is the text we need.

Through researching more the XML standard, I found that if I search for pStyle elements that contain the value “Heading2”, these will be the sections I’m after. To make my code a little cleaner, I wrote functions to both evaluate each section for the Heading 2 style and extract the full text of the section:

def is_heading2_section(p): """Returns True if the given paragraph section has been styled as a Heading2""" return_val = False heading_style_elem = p.find(".//w:pStyle[@w:val='Heading2']", ns) if heading_style_elem is not None: return_val = True return return_val def get_section_text(p): """Returns the joined text of the text elements under the given paragraph tag""" return_val = '' text_elems = p.findall('.//w:t', ns) if text_elems is not None: return_val = ''.join([t.text for t in text_elems]) return return_val section_labels = [get_section_text(s) if is_heading2_section(s) else '' for s in p_sections]

Now, if I print out my section_labels list, I see this:

Step 6: Finally, extract the Heading 2 headers and subsequent text

Now, I can use simple list comprehension to glue together both the section headers and associated text of the three sub-sections I’m after:

section_text = [ for i, t in enumerate(section_labels) if len(t) > 0]

And that list looks like this:
