You can use context variables for that.

To extract the name, request the name in 1º node, and in the next node, add this JSON:

{
  "context": {
    "name": "<? input.text ?>"
  },
  "output": {
    "text": {
      "values": [
        "Hello $name."
      ],
      "selection_policy": "sequential"
    }
  }
}

The input.text capture all user has typed.

You can use $ for set and get the context variable with the name: $name will show what user has typed.

In other case, if user typed my name is XXXXX, you can use regex inside your context variable. Check this example for use REGEX inside context variables:

   "name" : "<? input.text.extract('^[A-Z][-a-zA-Z]+$') ?>"

@MichelBida did one example with regex, but with another request for user, check this link.

EDIT:

Use:

context.myproperty = "Hello World";

And now have the System Entity @sys-person, this entity extracts names from the user's input. Names are not normalized by the system, so "Will" is not treated as "William", nor vice versa, see official documentation. This entity can be active within Entity -> System Entities -> @sys-person
