ASCII control characters in CDATA section

[nowhere]

Hi,

I need to preserve some ASCII control characters (CR and LF) within an
XML file so I have included the data in a CDATA section. However,
when parsing it using expat, I lose the CR characters.

My question is: Should I be using a different character set (not
UTF-8) or is this a bug in expat?

TIA, Mark

I don't think so, with XML all line endings are normalized
http://www.w3.org/TR/REC-xml#sec-line-ends
so even a CDATA section doesn't help to preserve a carriage return

To preserve CRs, you need to use character references (&#x0D;), because
CR and CR-LF are normalized to LF when an XML document is read.

You can't use character references in a CDATA section, so it's
probably better to forget about CDATA and just escape any characters
that need it. The main use for CDATA is preserving human readability
of text that includes < and & characters, such as XML examples inside
an XML document. It doesn't really work for arbitrary data.
