Help searching file

Question

The code segment below is attempting to read through the file until it reaches the "beginChar", once reached, this and all following strings or numbers are displayed(eventully added to a vector). Until the "endChar" is read in which case it halts. The code below does work up to a point but its very messy and ends by crashing. It also misses the next string after a number has been read.
My program attempted to add a douoble to a vector which was read from a file using the STream Tokenizer but wasnt allowed .
Anyone got any suggestions would be grateful cheers ; )
while((StreamTokenizer.TT_EOF != tokenizer.nextToken()))               {                     if ((StreamTokenizer.TT_WORD == tokenizer.ttype) && (tokenizer.sval.equals(beginChar)))                {                     System.out.println(tokenizer.sval);                     do{                          System.out.print(v);                          tokenizer.nextToken();                          if (StreamTokenizer.TT_WORD == tokenizer.ttype){                              System.out.println(tokenizer.sval);                              v.add(tokenizer.sval);                               }                              else if(StreamTokenizer.TT_NUMBER == tokenizer.ttype){                               System.out.println(tokenizer.nval);                               //v.add(tokenizer.nval);                               tokenizer.nextToken();                               }                              else                              {                                    System.out.println("Whatever");                                    System.out.print(v);                               }                    }while(!tokenizer.sval.equals(endChar));                    System.out.print("reached End");
