Manual linebreak and formatting docbook

Question

I am trying to make a simple help with Docbook. I need to format the text rather than letting text to be compact and non readable. It is better if the text can be set as it is being typed (i.e: preserve white spaces and line breaks)

So far I tried <?line-break?>, <?lb?> and <sbr/>. I only tried adding them to the position where I expect the line break as if using "\n" on C based language.

I am clueless of getting this done and I could not find any helpful resources. Any help appreciated regarding manual line break or formatting the text

With Docbook all the white space and line breaks can be preserved when using the tag <literallayout>. Where manual line breaks can also be done easily as if editing plain text!

<literallayout>
  O, for a muse of fire, that would ascend
The brightest heaven of invention!
A kingdom for a stage, princes to act,
And monarchs to behold the swelling scene!
</literallayout>

would give the output as,
