Line breaks and paragraph breaks
Line breaks and paragraph breaks

I am reading an attributed string and breaking it up into text runs
using attributesAtIndex:longestEffectiveRange:inRange:, now I need to
break the resulting ranges of text into any lines ends and paragraph
ends that occur within the range, so that I can output <br /> and <p /
> tags in the code at the line breaks and paragraph breaks
respectively, and process the text between the line/paragraph breaks
separately.
The problem is that getLineStart:end:contentsEnd:forRange: and
getParagraphStart:end:contentsEnd:forRange: seem to both detect line
breaks and call them paragraph breaks. I don't really understand what
the difference is between these two methods. What does it count as a
line and what as a paragraph? Seeing as a paragraph break is also
counted as a line break, what is the best way to emit either a <p />
or a <br /> but not both? Is there a way of typing a line break (not a
paragraph break) in an NSTextVew?
Any suggestions on the best way to handle this would be appreciated.
TIA
Gideon
