docx（DOCX 文档处理）

DOCX creation, editing, and analysis

Overview

A user may ask you to create, edit, or analyze the contents of a.docx file. A.docx file is essentially a ZIP archive containing XML files and other resources that you can read or edit. You have different tools and workflows available for different tasks.

Workflow Decision Tree

Reading/Analyzing Content

Use "Text extraction" or "Raw XML access" sections below

Creating New Document

Use "Creating a new Word document" workflow

Editing Existing Document

• Your own document + simple changes Use "Basic OOXML editing" workflow
• Someone else's document Use "Redlining workflow" (recommended default)
• Legal, academic, business, or government docs Use "Redlining workflow" (required)

Reading and analyzing content

Text extraction

If you just need to read the text contents of a document, you should convert the document to markdown using pandoc. Pandoc provides excellent support for preserving document structure and can show tracked changes:

# Convert document to markdown with tracked changes
pandoc --track-changes=all path-to-file.docx -o output.md
# Options: --track-changes=accept/reject/all

Raw XML access

You need raw XML access for: comments, complex formatting, document structure, embedded media, and metadata.

Key file structures

• word/document.xml - Main document contents
• word/comments.xml - Comments referenced in document.xml
• word/media/ - Embedded images and media files
• Tracked changes use <w:ins> (insertions) and <w:del> (deletions) tags

Creating a new Word document

When creating a new Word document from scratch, use docx-js, which allows you to create Word documents using JavaScript/TypeScript.

Workflow

1. Create a JavaScript/TypeScript file using Document, Paragraph, TextRun components
2. Export as.docx using Packer.toBuffer()

Editing an existing Word document

When editing an existing Word document, work with the raw OOXML format by unpacking, editing XML, and repacking.

Workflow

1. Unpack the document
2. Create and run a Python script to edit the XML
3. Pack the final document

Converting Documents to Images

To visually analyze Word documents, convert them to images using a two-step process:

1. Convert DOCX to PDF: soffice --headless --convert-to pdf document.docx
2. Convert PDF pages to JPEG images: pdftoppm -jpeg -r 150 document.pdf page This creates files like page-1.jpg, page-2.jpg, etc.

Code Style Guidelines

IMPORTANT: When generating code for DOCX operations:

• Write concise code
• Avoid verbose variable names and redundant operations
• Avoid unnecessary print statements

Dependencies

Required dependencies (install if not available):

• pandoc: sudo apt-get install pandoc (for text extraction)
• docx: npm install -g docx (for creating new documents)
• LibreOffice: sudo apt-get install libreoffice (for PDF conversion)
• Poppler: sudo apt-get install poppler-utils (for pdftoppm to convert PDF to images)
• defusedxml: pip install defusedxml (for secure XML parsing)
