问题:

I was looking to represent a carriage return within an xml node.
I have tried a whitespace preserve, hex entity with no luck- and a \n. viewing via a browser.

Example

<Quote>
Alas, poor Yorick!
I knew him
</Quote>

Thanks.

To insert a CR into XML, you need to use its character entity .

This is because compliant XML parsers must, before parsing, translate CRLF and any CR not followed by a LF to a single LF. This behavior is defined in the End-of-Line handling section of the XML 1.0 specification.

回答2:

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or  to insert CR/LF characters.

A browser isn't going to show you white space reliably. I recommend the Linux 'od' command to see what's really in there. Comforming XML parsers will respect all of the methods you listed.
