Usage 🚀

Importing the Library

To start using the library, import the necessary modules:

from docx_parser_converter.docx_to_html.docx_to_html_converter import DocxToHtmlConverter
from docx_parser_converter.docx_to_txt.docx_to_txt_converter import DocxToTxtConverter
from docx_parser_converter.docx_parsers.utils import read_binary_from_file_path

Quick Start Guide 📖

1. Convert to HTML:

   from docx_parser_converter.docx_to_html.docx_to_html_converter import DocxToHtmlConverter
   from docx_parser_converter.docx_parsers.utils import read_binary_from_file_path
   
   docx_path = "path_to_your_docx_file.docx"
   html_output_path = "output.html"
   
   docx_file_content = read_binary_from_file_path(docx_path)
   
   converter = DocxToHtmlConverter(docx_file_content, use_default_values=True)
   html_output = converter.convert_to_html()
   converter.save_html_to_file(html_output, html_output_path)
   

2. Convert to Plain Text:

   from docx_parser_converter.docx_to_txt.docx_to_txt_converter import DocxToTxtConverter
   from docx_parser_converter.docx_parsers.utils import read_binary_from_file_path
   
   docx_path = "path_to_your_docx_file.docx"
   txt_output_path = "output.txt"
   
   docx_file_content = read_binary_from_file_path(docx_path)
   
   converter = DocxToTxtConverter(docx_file_content, use_default_values=True)
   txt_output = converter.convert_to_txt(indent=True)
   converter.save_txt_to_file(txt_output, txt_output_path)
   

Supported XML Parsing Types 📄

The Docx Parser and Converter library supports parsing various XML components within a DOCX file. Below is a detailed list of the supported and unsupported components:

Supported Components

1. document.xml:

   • Document Parsing: Parses the main document structure.
   • Paragraphs: Extracts paragraphs and their properties.
   • Runs: Extracts individual text runs within paragraphs.
   • Tables: Parses table structures and properties.
   • Table Rows: Extracts rows within tables.
   • Table Cells: Extracts cells within rows.
   • List Items: Handles both bulleted and numbered lists through paragraph properties.

2. numbering.xml:

   • Numbering Definitions: Parses numbering definitions and properties for lists.
   • Numbering Levels: Extracts different levels of numbering for nested lists.

3. styles.xml:

   • Paragraph Styles: Extracts styles applied to paragraphs.
   • Run Styles: Extracts styles applied to text runs.
   • Table Styles: Parses styles applied to tables and table elements.
   • Default Styles: Extracts default document styles for paragraphs, runs, and tables.

Unsupported Components

• Images: Parsing and extraction of images embedded within the document.
• Headers and Footers: Parsing of headers and footers content.
• Footnotes and Endnotes: Handling footnotes and endnotes within the document.
• Comments: Extraction and handling of comments.
• Custom XML Parts: Any custom XML parts beyond the standard DOCX schema.

General Code Flow 🔄

The Docx Parser and Converter library follows a structured workflow to parse, convert, and merge document properties and styles according to DOCX specifications. Here’s a detailed overview of the technical process:

1. Parsing XML Files:

   • Document XML Parsing: The DocumentParser class reads and parses the document.xml file to extract the document structure, including paragraphs, tables, and runs. This data is converted into DocumentSchema Pydantic models.
   • Numbering XML Parsing: The NumberingParser class parses the numbering.xml file to extract numbering definitions and levels, converting them into NumberingSchema Pydantic models.
   • Styles XML Parsing: The StylesParser class parses the styles.xml file to extract styles for paragraphs, runs, and tables, converting them into StylesSchema Pydantic models.

2. Property and Style Merging:

   • Hierarchical Style Application: The library applies styles to paragraphs and runs based on a defined hierarchy. Explicit properties in the DocumentSchema remain unchanged, while styles are applied based on the style_id if present.
   • Default Style Application: If no specific style_id is present, default styles from StyleDefaults are applied. Finally, any remaining null properties are filled with default_rpr and default_ppr from the StylesSchema.
   • Efficient Property Merging: The merge_properties function is used to efficiently merge properties by converting Pydantic models to dictionaries, adding only non-null properties, and reassigning them to the original models.

3. Conversion to HTML and TXT:

   • DOCX to HTML:
     • The DocxToHtmlConverter class takes the parsed DocumentSchema and converts the document elements into HTML format.
     • Styles and properties are translated into equivalent HTML tags and CSS attributes.
     • The converted HTML content can be saved to a file using the save_html_to_file method.
     • WYSIWYG Support: The conversion maintains the visual representation of the document, ensuring accurate rendering of numbering, margins, and indentations as they appear in the original DOCX file.
   • DOCX to TXT:
     • The DocxToTxtConverter class converts the DocumentSchema into plain text format.
     • Paragraphs, lists, and tables are transformed into a readable plain text representation.
     • The converted text content can be saved to a file using the save_txt_to_file method.
     • WYSIWYG Support: The conversion preserves the structure of the document, maintaining numbering, margins, and indentations to ensure the text layout resembles the original document's format.

This detailed process ensures that the Docx Parser and Converter library accurately parses and converts DOCX documents while preserving the original document's structure and style as much as possible.
