You can deserialize complex nested Xml files into DTO Classes in Symfony in very simple steps using the JMS Serializer Bundle. Just follow these steps:

 

Step 1: Install Required Packages
Make sure you have the JMS Serializer Bundle installed. You can install it using Composer:

composer require jms/serializer-bundle

 

Step 2: Configure JMS Serializer Bundle
Configure the JMS Serializer Bundle in your Symfony application. Open your config/packages/jms_serializer.yaml file and add the following configuration:

jms_serializer:
    metadata:
        auto_detection: true

This configuration enables the JMS Serializer Bundle to automatically detect and use your DTO classes. For more configuration settings refer to the JMS Serializer Config page.
