Thread: How to convert string in url encoding to html encoding?

Hello, I am using a testing tool that uses C code and it has a function which will convert from HTML to URL or PLAIN but not URL to HTML. Does anyone have any code which would convert the following

Code:

"3%2635%3Dsaptest15001%2C8P%26S5%2C88%2663%3DsecEnterprise%2C8P%264F%3D462265%2C8P%264E%3D642037JfUyOifEckq6pX62%2C8P%26pa%2C8P%26Tm%3D3650%2C83%261%2C8P%262r%3Dcgar-bobjqapp2%3A6400%2C8P%26Tn%3D{3%26.2%3D{3%26O%3DPersonalCategory%2C0P%262%3D462327%2C03}%2C2z%26.1%3D{3%26O%3DFavoritesFolder%2C0P%262%3D462326%2C03}%2C2z%26.3%3D{3%26O%3DInbox%2C0P%262%3D462328%2C03}%2C2z%26U%3D3%2C03}%2C%3Fz%263k%3D%40BOBJ_QA%2C8P%265U%3D642038JhpJ4sSqGXzP9rYn642037JfUyOifEckq6pX62%2C8P"

to

"3&35=saptest15001,8P&S5,88&63=secEnterprise,8P&4F=462265,8P&4E=642037JfUyOifEckq6pX62,8P&pa,8P&Tm=3650,83&1,8P&2r=cgar-bobjqapp2:6400,8P&Tn={3&.2={3&O=PersonalCategory,0P&2=462327,03},2z&.1={3&O=FavoritesFolder,0P&2=462326,03},2z&.3={3&O=Inbox,0P&2=462328,03},2z&U=3,03},?z&3k=@BOBJ_QA,8P&5U=642038JhpJ4sSqGXzP9rYn642037JfUyOifEckq6pX62,8P"

I've run out of ideas on how to accomplish this task. I would like to be able to reuse the code in the future as I am sure I will see this need again.

Its very easy with string functions like:

Code:

void transformed(char *s)
{
  char *ent[]={"&","<",">","""," "},
  *pre="&<>\" ",
  c[2]={0};
  int x;
  while( *s )
    if( sscanf(s,"%%%02x",&x) )
      s+=3,printf("%s",strchr(pre,x)?ent[strchr(pre,x)-pre]:(*c=x,c));
    else
      putchar(*s++);
}

transformed("3%2635%3Dsaptest15001%2C8P%26S5%2C88%2663%3DsecEnterprise%2C8P...");

To change the code to put in a string and not to stdout is your work.

First, thank you for the reply. I am always willing to learn but I am not understanding the logic. To convert 3%2635%3Dsaptest15001%2C8P%26S5%2C88%2663%3DsecEnt erprise%2C8P to 3&35=saptest15001,8P&S5,88&63=secEnter prise,8P how do you do that? It appears your code is going the other way as "transformed" is what I am converting from. Thx.

This is code I was working on trying to get S_Cookie1 to convert to S_CORRECT. I was going through each URL encoded and trying to convert to HTML but was overwriting itself and the code was choking the compiler.

Code:

lr_save_string("3%2635%3Dsaptest15001%2C8P%26S5%2C88%2663%3DsecEnterprise%2C8P%264F%3D462265%2C8P%264E%3D642037JfUyOifEckq6pX62%2C8P%26pa%2C8P%26Tm%3D3650%2C83%261%2C8P%262r%3Dcgar-bobjqapp2%3A6400%2C8P%26Tn%3D%7B3%26.2%3D%7B3%26O%3DPersonalCategory%2C0P%262%3D462327%2C03%7D%2C2z%26.1%3D%7B3%26O%3DFavoritesFolder%2C0P%262%3D462326%2C03%7D%2C2z%26.3%3D%7B3%26O%3DInbox%2C0P%262%3D462328%2C03%7D%2C2z%26U%3D3%2C03%7D%2C%3Fz%263k%3D%40BOBJ_QA%2C8P%265U%3D642038JhpJ4sSqGXzP9rYn642037JfUyOifEckq6pX62%2C8P","S_Cookie1");

MK27 I understand your comments however my concern is the conversion that I am after needs to be passed back to the server in the S_CORRECT format. It gets passed back in a SOAP envelope. I also agree with you that the method we were trying to get working is awkward but we were grasping at straws trying to come up with something. Can't remember if I mentioned this but our test tool has a function that will convert from HTML to URL or HTML to PLAIN but not the other way around. This code would get used in a test script so I would have to account for any delay in this process of conversion.
