xml.sax removing newlines from attribute value?

[Grant Edwards]

I'm using xml.sax to parse the "datebook" xml file generated by
QTopiaDesktop. When I look at the xml file, some of the
attribute strings have newlines in them (as they are supposed
to).

However, when xml.sax passes the attributes to my
startElement() method the newlines seem to have been deleted.

How do I get the un-munged element attribute values?

newlines as in chr(10) rather than 
 ?

if so, the only way is to avoid XML:

http://www.w3.org/TR/REC-xml/#AVNormalize

if the "yes, I know, but I have good reasons" approach is okay with you,
and you're big enough to defend yourself against the XML-Is-The-Law
crowd, you can use a "sloppy" XML parsers such as sgmlop to deal with
your files:

Yup, Looks that way.

I can't quite find it in the BNF, but I take it that chr(10)
isn't really allowed in XML attribute strings. IOW, the file
generate by Trolltech's app is broken.

I didn't define the file or write the program that generated
it. It's claimed to be "xml", and I'm just trying to parse it.

Good to know for future reference. For now, I think I'll just
live with the way it works. Everything basically works, except
some strings don't display quite "right". My current app
treats the file as read-only. If I ever get around to
modifying data and writing it back, I'll probably have to deal
with the newline issue at that point.

it's allowed, but the parser must not pass it on to the application.

(in other words, whitespace in attributes doesn't, in general, survive
roundtripping)

Ah, I see. That's good to know.

[This is my first attempt at anything XMLish.]
