[plt-scheme] X-expressions, HTML and a nonbreaking space ( )

Thu Oct 21 10:04:46 EDT 2004

Actually, I just made a typo in my response because I misread how your 
code worked. The symbol nbsp should not be in quotes; it should just be 
a symbol directly in your x-expression.

 > (define lhtml
    `(html
      (head
       (title "Flight Information"))
      (body
       (h2 "Item 1")(br) nbsp (h2 "Item 2"))))
 > (write-xml/content (xexpr->xml lhtml))
<html><head><title>Flight Information</title></head><body><h2>Item 
1</h2><br />&nbsp;<h2>Item 2</h2></body></html>
