Task 150: .DOTX File Format

Task 150: .DOTX File Format

File Format Specifications for .DOTX

The .DOTX file format represents a Microsoft Word Open XML Document Template, as defined in the Office Open XML (OOXML) standards under ISO/IEC 29500 and ECMA-376. It serves as a template for creating .DOCX documents, incorporating predefined settings such as styles, layouts, and formatting. Structurally, .DOTX adheres to the Open Packaging Conventions (OPC), utilizing a ZIP archive container that holds XML files for content, relationships, and metadata. The format is macro-free, distinguishing it from .DOTM (macro-enabled templates), and follows the same foundational structure as .DOCX but with a content type of application/vnd.openxmlformats-officedocument.wordprocessingml.template. Key components include [Content_Types].xml for part definitions, _rels/.rels for relationships, word/document.xml for the main template content, and docProps folders for properties.

1. List of Properties Intrinsic to the .DOTX File Format

The properties intrinsic to the .DOTX format are primarily metadata fields stored within the ZIP archive, specifically in docProps/core.xml (core properties), docProps/app.xml (extended properties), and optionally docProps/custom.xml (custom properties). These properties are standardized in the OOXML specification (Part 2: Open Packaging Conventions) and can be extracted without external dependencies. Custom properties are user-defined and variable, so they are not exhaustively listed but can include name-value pairs of various data types.

The following table enumerates all standard properties:

Category Property Name Description Data Type
Core Title The document's title. String
Core Subject The document's subject. String
Core Creator The author or creator. String
Core Keywords Keywords associated with the document. String
Core Description A textual description. String
Core LastModifiedBy The last user to modify the document. String
Core Revision The revision number. Integer
Core Created The creation date and time. DateTime
Core Modified The last modification date and time. DateTime
Core Category The document category. String
Core ContentStatus The content status (e.g., Draft, Final). String
Core ContentType The content type. String
Core Identifier A unique identifier. String
Core Language The primary language. String
Core Version The version number. String
Core LastPrinted The last print date and time. DateTime
Extended Application The application that created the file (e.g., Microsoft Word). String
Extended AppVersion The version of the application. String
Extended Company The company or organization. String
Extended DocSecurity Document security level (0-4). Integer
Extended HeadingPairs Vector of heading pairs for outline. Vector
Extended HyperlinksChanged Indicates if hyperlinks have changed. Boolean
Extended HyperlinkBase Base URL for hyperlinks. String
Extended LinksUpToDate Indicates if links are up to date. Boolean
Extended Manager The document manager. String
Extended Pages Number of pages. Integer
Extended Paragraphs Number of paragraphs. Integer
Extended ScaleCrop Indicates if thumbnails are scaled or cropped. Boolean
Extended SharedDoc Indicates if the document is shared. Boolean
Extended Template The template file name. String
Extended TitlesOfParts Titles of document parts. Vector
Extended TotalTime Total editing time in minutes. Integer
Extended Words Number of words. Integer
Extended Characters Number of characters (excluding spaces). Integer
Extended CharactersWithSpaces Number of characters (including spaces). Integer
Extended Lines Number of lines. Integer
Custom (Variable) User-defined properties (e.g., name-value pairs). Varies (String, Integer, Date, Boolean)

These properties are embedded in the file's structure and can be read, modified, and written back to maintain format integrity.

3. Embedded HTML/JavaScript for Drag-and-Drop .DOTX Property Dump

The following is an embeddable HTML snippet with JavaScript for a Ghost blog. It creates a drag-and-drop area where a user can drop a .DOTX file. The script uses the JSZip library (which must be included via CDN) to unzip the file, parse the XML files in docProps, extract the properties listed above, and display them on the screen. Custom properties are handled if present.

4. Python Class for .DOTX Property Handling

The following Python class uses the zipfile and xml.etree.ElementTree modules to open a .DOTX file, decode and read the properties, print them to the console, and write updated properties back to a new file.

import zipfile
import xml.etree.ElementTree as ET
from io import BytesIO

class DotxPropertyHandler:
    def __init__(self, filepath):
        self.filepath = filepath
        self.properties = {}
        self.core_ns = {'cp': 'http://schemas.openxmlformats.org/package/2006/metadata/core-properties',
                        'dc': 'http://purl.org/dc/elements/1.1/',
                        'dcterms': 'http://purl.org/dc/terms/'}
        self.app_ns = {'ep': 'http://schemas.openxmlformats.org/officeDocument/2006/extended-properties'}
        self.custom_ns = {'cust': 'http://schemas.openxmlformats.org/officeDocument/2006/custom-properties'}
        self.read_properties()

    def read_properties(self):
        with zipfile.ZipFile(self.filepath, 'r') as z:
            core_xml = z.read('docProps/core.xml') if 'docProps/core.xml' in z.namelist() else None
            app_xml = z.read('docProps/app.xml') if 'docProps/app.xml' in z.namelist() else None
            custom_xml = z.read('docProps/custom.xml') if 'docProps/custom.xml' in z.namelist() else None

            if core_xml:
                core_root = ET.fromstring(core_xml)
                self.properties['Title'] = core_root.find('dc:title', self.core_ns).text if core_root.find('dc:title', self.core_ns) is not None else None
                self.properties['Subject'] = core_root.find('dc:subject', self.core_ns).text if core_root.find('dc:subject', self.core_ns) is not None else None
                # Similarly for other core properties...
                # (Omitted for brevity; add finds for Subject, Creator, Keywords, etc., as in the JS example)

            if app_xml:
                app_root = ET.fromstring(app_xml)
                self.properties['Application'] = app_root.find('ep:Application', self.app_ns).text if app_root.find('ep:Application', self.app_ns) is not None else None
                # Similarly for other extended properties...

            if custom_xml:
                custom_root = ET.fromstring(custom_xml)
                self.properties['CustomProperties'] = [
                    {'name': prop.attrib['name'], 'value': prop[0].text, 'type': prop[0].attrib['{http://www.w3.org/2001/XMLSchema-instance}type']}
                    for prop in custom_root.findall('cust:property', self.custom_ns)
                ]

    def print_properties(self):
        for key, value in self.properties.items():
            print(f"{key}: {value}")

    def write_properties(self, new_properties, output_path):
        with zipfile.ZipFile(self.filepath, 'r') as z_in:
            with zipfile.ZipFile(output_path, 'w') as z_out:
                for item in z_in.infolist():
                    if item.filename == 'docProps/core.xml':
                        core_root = ET.fromstring(z_in.read(item))
                        for key, value in new_properties.items():
                            if key in ['Title', 'Subject', ...]:  # Check against core keys
                                elem = core_root.find(f"dc:{key.lower()}", self.core_ns) or core_root.find(f"cp:{key.lower()}", self.core_ns)
                                if elem is not None:
                                    elem.text = str(value)
                        z_out.writestr(item.filename, ET.tostring(core_root))
                    elif item.filename == 'docProps/app.xml':
                        # Similar update for app.xml
                        pass
                    elif item.filename == 'docProps/custom.xml':
                        # Similar for custom
                        pass
                    else:
                        z_out.writestr(item, z_in.read(item))

# Example usage:
# handler = DotxPropertyHandler('example.dotx')
# handler.print_properties()
# handler.write_properties({'Title': 'New Title'}, 'updated.dotx')

(Note: The full implementation for all property finds and writes is abbreviated for conciseness; extend the finds and updates accordingly.)

5. Java Class for .DOTX Property Handling

The following Java class uses java.util.zip and javax.xml.parsers to handle .DOTX files similarly.

import java.io.*;
import java.util.*;
import java.util.zip.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.InputSource;

public class DotxPropertyHandler {
    private String filepath;
    private Map<String, Object> properties = new HashMap<>();

    public DotxPropertyHandler(String filepath) {
        this.filepath = filepath;
        readProperties();
    }

    private void readProperties() {
        try (ZipFile z = new ZipFile(filepath)) {
            ZipEntry coreEntry = z.getEntry("docProps/core.xml");
            if (coreEntry != null) {
                Document coreDoc = parseXml(z.getInputStream(coreEntry));
                properties.put("Title", getNodeValue(coreDoc, "title", "http://purl.org/dc/elements/1.1/"));
                // Add for other core properties...
            }
            ZipEntry appEntry = z.getEntry("docProps/app.xml");
            if (appEntry != null) {
                Document appDoc = parseXml(z.getInputStream(appEntry));
                properties.put("Application", getNodeValue(appDoc, "Application", "http://schemas.openxmlformats.org/officeDocument/2006/extended-properties"));
                // Add for other extended...
            }
            ZipEntry customEntry = z.getEntry("docProps/custom.xml");
            if (customEntry != null) {
                // Parse custom...
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private Document parseXml(InputStream is) throws Exception {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        DocumentBuilder builder = factory.newDocumentBuilder();
        return builder.parse(new InputSource(is));
    }

    private String getNodeValue(Document doc, String tag, String ns) {
        NodeList nodes = doc.getElementsByTagNameNS(ns, tag);
        return nodes.getLength() > 0 ? nodes.item(0).getTextContent() : null;
    }

    public void printProperties() {
        properties.forEach((key, value) -> System.out.println(key + ": " + value));
    }

    public void writeProperties(Map<String, Object> newProperties, String outputPath) {
        // Similar to Python: read zip, update XML docs, write new zip
        // Implementation omitted for brevity; use Transformer to update and write.
    }

    // Example usage in main method...
}

(Note: Full parsing and writing logic is abbreviated; implement additional node retrievals and XML transformations as needed.)

6. JavaScript Class for .DOTX Property Handling

The following JavaScript class (for Node.js) uses adm-zip and xml2js libraries (assume installed via npm) to handle .DOTX files.

const AdmZip = require('adm-zip');
const xml2js = require('xml2js');

class DotxPropertyHandler {
    constructor(filepath) {
        this.filepath = filepath;
        this.properties = {};
        this.readProperties();
    }

    async readProperties() {
        const zip = new AdmZip(this.filepath);
        const coreXml = zip.readAsText('docProps/core.xml');
        if (coreXml) {
            const parser = new xml2js.Parser({ explicitArray: false });
            const core = await parser.parseStringPromise(coreXml);
            this.properties.Title = core['cp:coreProperties']['dc:title'];
            // Add other core...
        }
        const appXml = zip.readAsText('docProps/app.xml');
        if (appXml) {
            const app = await parser.parseStringPromise(appXml);
            this.properties.Application = app.Properties.Application;
            // Add other extended...
        }
        // Custom similar...
    }

    printProperties() {
        console.log(this.properties);
    }

    writeProperties(newProperties, outputPath) {
        const zip = new AdmZip(this.filepath);
        // Parse, update objects, build new XML with xml2js.Builder, update zip entries, zip.writeZip(outputPath);
        // Implementation details omitted.
    }
}

// Usage: const handler = new DotxPropertyHandler('example.dotx'); handler.printProperties();

(Note: Requires npm install adm-zip xml2js; full property mapping and write logic abbreviated.)

7. C++ Class for .DOTX Property Handling

The following C++ class uses libzip and tinyxml2 libraries (assume linked) to handle .DOTX files.

#include <zip.h>
#include <tinyxml2.h>
#include <iostream>
#include <map>
#include <string>

class DotxPropertyHandler {
private:
    std::string filepath;
    std::map<std::string, std::string> properties;

public:
    DotxPropertyHandler(const std::string& fp) : filepath(fp) {
        readProperties();
    }

    void readProperties() {
        zip_t* z = zip_open(filepath.c_str(), 0, nullptr);
        if (z) {
            zip_file_t* coreFile = zip_fopen(z, "docProps/core.xml", 0);
            if (coreFile) {
                // Read buffer, load into tinyxml2::XMLDocument
                tinyxml2::XMLDocument doc;
                // doc.Parse(buffer);
                // properties["Title"] = doc.FirstChildElement("cp:coreProperties")->FirstChildElement("dc:title")->GetText();
                // Add others...
                zip_fclose(coreFile);
            }
            // Similar for app and custom...
            zip_close(z);
        }
    }

    void printProperties() {
        for (const auto& p : properties) {
            std::cout << p.first << ": " << p.second << std::endl;
        }
    }

    void writeProperties(const std::map<std::string, std::string>& newProps, const std::string& outputPath) {
        // Open zip, extract, modify XML with tinyxml2, add back to new zip archive.
        // Details omitted.
    }
};

// Usage in main: DotxPropertyHandler handler("example.dotx"); handler.printProperties();

(Note: Requires libzip and tinyxml2; full buffer reading, parsing, and writing logic abbreviated for conciseness.)
