XMLSerializer attributes and carriage returns - bug?

[Thomas Greenwood <tg...@exel.co.uk>]

I have an XML document that contains carriage returns and line feeds in
attributes.  When I serialize this document with XMLSerializer these
carriage returns and line feeds appear in the output as exactly that - but
this then causes problems using the document as an XSLT, escaping the
carriage returns and line feeds stops any problems.  I have written some
code that should fix these problems, but was this by design or is this a
bug?  If this is a bug then I'll send my new code sample in with a bug
report, if not is there any way to get the current XMLSerializer to escape
the carriage returns and line feeds in attributes (does not look like there
is any code to do this)?

Thanks

Do you mean that you have done:

Element someElement = doc.createElement("e");
someElement.setAttribute("foo", "abc\ndef");

then tried to serialize a document containing the above attribute,
hoping to get this?

  <e foo="abc&#x0a;def"/>

but instead got this?

  <e foo="abc
def"/>

It's hard to offer specific advice without seeing a specific example, but:

1) Remember that XML normalizes whitespace, and an XSLT stylesheet is an 
XML document. You may indeed have to escape some characters to keep them 
from being normalized away, if that's what you want.

2) Make sure you understand XSLT's rules for handling whitespace. They're 
somewhat complicated, since they involve which XSLT element the whitespace 
appears in, the <xsl:strip-space> and <xsl:preserve-space> directives, and 
the xml:space attribute (if present in the document).
