Compare of Variables and Document properties Leave feedback
On this page
GroupDocs.Comparison allows you to compare various properties of a Word document such as Variable, Built, and Custom properties.
Use the following methods of the CompareOptions class to enable comparison functions for document properties:
setCompareVariableProperty()allows the comparison of variable propertiessetCompareDocumentProperty()allows the comparison of built and custom properties
The following code snippet shows how to activate the comparison of the variable, built and custom properties:
'use strict';
// Import the GroupDocs Comparison Node.js SDK
const groupdocs = require('@groupdocs/groupdocs.comparison');
// Enable strict mode for better error handling
// Define file paths for source, target, and output documents
const sourcePath = 'sample-files/source.docx';
const targetPath = 'sample-files/target.docx';
const outputPath = 'result.docx';
// Initialize the comparer with the source document
const comparer = new groupdocs.Comparer(sourcePath);
// Add the target document to be compared against the source
comparer.add(targetPath);
// Create a CompareOptions instance to customize comparison settings
const options = new groupdocs.CompareOptions();
// Enable comparison of variable (custom) properties
options.setCompareVariableProperty(true);
// Enable comparison of built-in document properties
options.setCompareDocumentProperty(true);
// Execute the comparison and save the result to the output path
comparer.compare(outputPath, options);
// Terminate the process with a success exit code
process.exit(0);
This example creates a Comparer instance with the source document, adds the target document, and creates a CompareOptions object. It enables comparison of both variable properties (using setCompareVariableProperty(true)) and document properties including built-in and custom properties (using setCompareDocumentProperty(true)), then performs the comparison with these options. Any differences in document properties will be highlighted in the result document.
The result is as follows:
