How to split string? 1

[KenChristensen]

Hi,

Iam working on a html editor and I am making a funktion for users to edit html tags.
(ex: user marks a line in editor and it opens a form. Then the form gets the information from the lins).

But how do I split the string so i get the text between the 2 first "s and the next 2? Ken Christensen

I am not sure that I really understand your question. But the HyperString library has some really useful functions in it.

In particular, you will probably find that one of the Parse functions will do what you require.

I used this bit of code to separate path and name of a file.

speech_marks := 0;
for counter := 1 to Length(MyString) do
  if(IsDelimiter('"', MyString, counter)) then
  begin   
    speech_marks := speech_marks + 1;
    case speech_marks of
      1: first_pos := counter;
      2: second_pos := counter;
      3: third_pos := counter;
      4: fourth_pos := counter;
    end;
  end;
end;

FirstWord := Copy(MyString, first_pos, second_pos);
SecondWord := Copy(MyString, third_pos, fourth_pos);

Not sure this is the best way to do it, but it should work ok!

Forget the line above the code - forgot to change it!!

Hi Stretchwicster,

Thanks for the reply..
But.
Can you please come with an example using your code? Ken Christensen

Ok...I used this bit of code to separate path and name of a file:

  db_length := Length(db_path_and_name);
  for counter := 1 to db_length do
    if(IsDelimiter('\', db_path_and_name, counter)) then
      final_delimiter := counter; 
      {indicates position of backslash in string}
  
  db_path := Copy(db_path_and_name, 1, final_delimiter);
  db_name := Copy(db_path_and_name, final_delimiter + 1, db_length);

Basically when the for loop is terminated

 final_delimiter

will store the position of the last backslash in the string.

For dir paths and filenames you can sue ExtractFileDir and ExtractFileName.

Thanks Lou! I obviously didn't look hard enough!
