You can use `Id2String` or define your own using `STRING.token2string` hook as follows:

syntax String ::= HexConstant2String ( HexConstant ) [function, hook(STRING.token2string)]

Hello Team,

I would like to parse a hex constant like

```
syntax HexConstant ::= r"0x[0-9a-fA-F]*" [token]
```
and use the hook `STRING.string2base` to get the `Int` equivalent, like

```
syntax Int ::= HexStringtToInt(String, Int) [function, hook(STRING.string2base)]

rule convert(S:String) => HexStringtToInt(S, 16)
```

but for that i need the hex as String,
which I could not find how to get.

Can you guys please me with that?

Regards,
Sandeep
