Update record field value

Learning

Hi,

I have following record:

type node_t = Element of element_t | Text of text_t

and element_t = {
tag_name: string
children: node_t list;
mutable deleted: bool
}

and text_t = {
text: string;
line_number: int;
}

Now, I have a XML node stored in a variable called xml_node
And the data is :

xml_node = Element {tag_name = "cell"; children: []; deleted = false}

I want to update the deleted flag as “deleted=true” in the above node record.

Could you please tell me how to do it?

Thank you in advance
