Extract function and line break

Problem Statement: I am trying to extract a list of string from an html content using the extract function and a combination of striphtml() and substitute(). The list of string contains a couple of line breaks but the extract function is stripping the line breaks. My goal is to keep the line breaks intact. I tried substituting the line breaks with space, it works. But char(13) does not work.

Sample code:

substitute(
  extract(
    striphtml(
      substitute(
        substitute(
          substitute(
            pv!htmlBody,
            "<p class=MsoPlainText>",
            "["
          ),
          "</p>",
          "]"
        ),
        "<br>",
        " "
      )
    ),
    trim(
      "Additional Comments:"
    ),
    trim(
      "Your Workgroup"
    )
  ),
  "][",
  char(
    13
  )
)
