Re: Search and replace on a string

[Kevin Anthony <kevin s anthony gmail com>]

here's how i do it:

gchar* replace_str (const gchar *src,const gchar *find,const gchar *replace){

    gchar* retval = g_strdup(src);

    gchar* ptr = NULL;

    ptr = g_strstr_len(retval,-1,find); 

    if (ptr != NULL){

        gchar* after_find = replace_str(ptr+strlen(find),find,replace);

        gchar* before_find = g_strndup(retval,ptr-retval);

        gchar* temp = g_strconcat(before_find,replace,after_find,NULL);

        g_free(retval);

        retval = g_strdup(temp);

        g_free(before_find);

        g_free(temp);

    }   

    return retval;

}

I need to search some text in a big string ansd replace it with some other text.
The big string is null terminated and so is the replacement text.
I read that I can find the wanted text with g_strstr_len, but I can't figure out how can I do the substitution once I found the text.
Can please someone help me?
Pseudo code or just a hint will be appreciated.
TIA
