Can a json string contain HTML tags with it?

Question

Consider this my json string,

[{"Mat_id" : "2","Mat_Name" : "Steel",
"Measurement" : "mm","Description" : "Steel"}] 

Can i add HTML Tags inside this json string like this,

[{"Mat_id" : "2","Mat_Name" : "Steel",
    "Measurement" : "<bold>mm</bold>","Description" : "Steel"}]

• Whether this is a valid json string?
• When Eval('('+ thisstring +')') will raise an issue? If so what is it?

I am doing so because i will pass this json object to a yui datatable which consumes json datasource...

EDIT:

This my resulted json string,

{"Table" : [{"Mat_id" : "2",
"Mat_Name" : "Jully","Measurement" : "<bold>Inches</bold>",
 "Description" : "Gully"},]}

But i didnt get my Measurement column values in bold...

Answer 1

Yeah.. no problem with that. :)

Answer 2

Technically, yes, you can do that... practically, I'd be a bit concerned if there were HTML markup in my data. What else might be in there? Smells like an XSS vulnerability.
