String to KeyValues

Ciao,

is there any possibility how to convert string to KeyValues tree? I need something like:

PHP Code:


		
			
// example inspired by https://wiki.alliedmods.net/KeyValues_(SourceMod_Scripting)#Basic_Lookup

new String:MyDataString[256] = "\"MyStructure\"{ \"STEAM_0:0:7\"{ \"name\" \"crab\"} }";
.
.
.
.
GetNameFromSteamID( PlayerSteamID, PlayerName, 32, MyDataString ); // PlayerSteamID and PlayerName are just for example
.
.
.
.
bool:GetNameFromSteamID(const String:steamid[], String:name[], maxlength, String:DataString[])
{
    new Handle:kv = CreateKeyValues("MyStructure");

    StringToKeyValues(kv, DataString); // need this function

    if (!KvJumpToKey(kv, steamid))
    {
        return false;
    }
    KvGetString(kv, "name", name, maxlength);
    CloseHandle(kv);
    return true;
}

I don't wanna make a new file with KeyValues structure and then convert this file to KeyValues. I wanna make string (e.g. pass throw function argument) ang this string convert to KeyValues.

Re: String to KeyValues

You were saying something like this, yes??

Code:

"MyStructure"

{

        "STEAM_0:0:0000"

        {

                "name"        "On_my_crab"

        }

        

        // or

        

        "LickMe_KickYou"

        {

                "SteamID"        "STEAM_0:0:0000"

                "name"                "Oh_my_crab"

        }

}

and this one should be..

PHP Code:


		
			
if (!KvJumpToKey(kv, steamid))

{

    CloseHandle(kv);

    return false;

}

Re: String to KeyValues

No, that was just an example (with mistake copied from SM wiki :-D ). The main thing I need is function

PHP Code:


		
			
StringToKeyValues(kv, DataString);

Because I don't wanna make KeyValues from file but from string. Now I found json https://forums.alliedmods.net/showth...highlight=json do you think that use json is better solution than KeyValues?

Re: String to KeyValues

As far as i concern, keyValue is string.
Why you want "StringToString"?

EDIT: Pardon my poor english but i don't realy understand it.

Re: String to KeyValues

Well, I don't mean KeyValues like string but like KeyValues tree. I just wanna iterate throw the KeyValues tree via function KvGotoNextKey(kv) etc. and only function to get existed KeyValues structure is via FileToKeyValues(kv, "myfile.txt") but I wanna use string instead of file.

So what I want is

PHP Code:


		
			
new Handle:kv = CreateKeyValues("MyStructure");

StringToKeyValues(kv, DataString);

and then

PHP Code:


		
			
do

{

// code

} while (KvGotoNextKey(kv));

I want this to pass KeyValues between functions. One function make a string and another function process this KeyValues string via function KvGotoNextKey(kv).

Now i think use json is better that KeyValues, but I am not sure..

Re: String to KeyValues

PHP Code:


		
			
StringToKeyValues( Handle:Kv, const String:SAVEPath[], const String:DataString[], const String:Buff[]  )

{

    decl String:Value[32][128];

    FileToKeyValues( Kv, SAVEPath );

    KvGotoFirstSubKey( Kv, false );

    

    new i;

    do

    {

        KvGetSectionName( Kv, Value[i], 15 );

        i++;

    }

    while ( KvGotoNextKey( Kv,false ));

    KvRewind( Kv );

    

    // retriv data from keyvalue. Maybe what you looking for

    KvJumpToKey( Kv, DataString, false);

    KvGetString( Kv, Value[0], Buff, sizeof( Buff ), "Null" );

    KvRewind( Kv );

}

I fail.. :cry:
