XML : insert blank line from xml to pdf

being new to xml, I am currently working on a task involving writing an xml using notepad and converting it to pdf.

below is my sample:

  <?xml version="1.0" encoding="utf-8"?>  <Noti>  <title><b>LETTER&#xA;</b></title>  <summary>how to&#xA;</summary>  <summary>insert&#xA;</summary>   <summary>break&#xA;</summary>  <summary>line&#xA;</summary>  </Noti>    

After reading a related thread adding-a-new-line-break-tag-in-xml and using pdfconverter to convert the xml file to pdf I still get in my pdf:

  LETTER how to insert break line    

instead of:

  LETTER    how to    insert    break    line    

Hoping to get some explanation about this phenomenon

Best,
