Extracting strings from a file. - Whizion - 14.01.2011

So recently because of my scripting error some files were written wrong and now i want to fix that.

Here's an example of my file (it doesn't look like this, it's just a example):

So what i want to do is, to extract all the red parts in the file (there's over 500, so it's hard to do it manualy).

What i know is this, every part that i need to extract starts with "user- and the rest is the username ended by a ".

I tryed something with strcmp, strfind etc. but i failed.

Could somebody please write me some code that could do this? Thank you.

hm.. could you please upload 2 or 3 complete files to solidfiles? i want to have a look on them with an ascii editor... i hope to find some 0x0a chars, those are returns, i will try to sscanf for "%d%z" and compare if the %d is a number followed by one of those 0x0a. if the remaining %z string is not numeric, it can be saved to another file... well, iam ready to roll ^^

What the hell.

Whoa, thanks for the quick response.

Well it's not the same but i recreated it using dummy text: http://solidfiles.com/d/3956f/

One thing is certain it begins with "user-HEREGOESUSERNAME and ends with ".

Thanks a lot.

Re: Extracting strings from a file. - Finn - 14.01.2011

If the username is between " 's, what's the problem here?

pawn Код:

new File:example = fopen("lol.txt", io_read);
    
new string[256], name[64];
while(fread(example, string))
{
    new i, start = -1;
    while(string[i])
    {
        if(string[i] == '"')
        {
            if(start != -1)
            {
                strmid(name, string, start, i);
                break;
            }
            else
            {
                start = (i + 1);
            }
        }
        i++;
    }
        
    print(string);
    print(name);
}
    
fclose(example);

Edit: If you don't want the 'user-' to be included, simply change this part:

pawn Код:

start = (i + 1);

to this:

pawn Код:

start = (i + 6);

There might be more " 's than those associated with the user-, will this code work for that to?

Thanks.

No, it doesn't.

Your example text didn't have " 's elsewhere, so I thought that's how it is, sorry 'bout that.

Re: Extracting strings from a file. - Babul - 14.01.2011

@ Whizion: well, nvm. i guess Finn will do that for ya by reverting your file-write-routine. if the whole user file looks like your fake one, then you could create a macro using a tool like autohotkey, and find each "user- ,mark some chars (24 maybe?), copy them, paste them to another window, and repeat.
@ Finn. "what the hell" ? what do you mean? i guess youre smart enough to get what i asked for (despite my horrible english), so whats the prob? are you afraid iam stealing his userdata? or you got a problem that iam analyzing his little fakeuserdata.txt with another program to cut out a simple string after a "user- like its possible with EXIF informations in any picture?

btw in the whole time we spent arguing about this little shit, one of us could have fixed that by doing it in notepad, unless you already got 100k players ^^
