Run Java code in local

java -jar xml-compare-0.0.1-SNAPSHOT-jar-with-dependencies.jar <Input XML1 path> <Input XML2 path> <Output XLS path>

Eg:

java -jar xml-compare-0.0.1-SNAPSHOT-jar-with-dependencies.jar /home/ravi/Desktop/Projects/xml-compare/src/main/resources/XML1.xml /home/ravi/Desktop/Projects/xml-compare/src/main/resources/XML2.xml /home/ravi/Desktop/Projects/xml-compare/src/main/resources/Results2.xls

Run as Docker image

docker run -p 8084:8080 -v <local path>:/usr/src -t ravikalla/xml-compare /usr/src/<XML1 filename> /usr/src/<XML2 filename> /usr/src/<Results.xls filename>

Eg:

docker run -p 8084:8080 -v /home/ravi/Desktop/Projects/xml-compare/src/main/resources:/usr/src -t ravikalla/xml-compare /usr/src/XML1.xml /usr/src/XML2.xml /usr/src/Results.xls

Usage Notes

• Input validation: The tool validates file paths and accessibility before processing
• Error handling: Clear error messages for common issues (file not found, permission errors, etc.)
• Output format: Results are generated in Excel (.xls) format with separate sheets for matches and mismatches
