You should set s1.StrictDelimiter := True for spaces not to be considered delimiters, more info here.
Since you work in a version that does not support the above (as was clarified after the answer was submitted), you have two options:
- Find a character you know will not be used in the original text (e.g. underscore), convert all spaces to that character before splitting, and convert back after splitting. This is robosoft’s suggestion.
- If you don’t have inverted commas and spaces in the text, you can use Alexander’s trick and wrap the text between delimiters in inverted command, so that
'hello hello^bye bye'turns to'"hello hello"^"bye bye"'. If you do choose this path and it works for you, please accept Alexander’s answer and not mine, he also provides the code to implement it.
Both workarounds not using StrictDelimiter have limitations: the first requires some unused character, and the second requires no inverted commas and spaces in the original text.
Maybe it’s time to upgrade to a newer version of Delphi 🙂
