Brightman MkhwanaziSubject: Compressed content in CADATA

I have an xml document that has CDATA with compressed content. I am getting this error when opening the file :

Invalid character (Unicode: 0x1F)

I have attached the xml document.

I think the issue is with character encoding for compressed content.

That's not valid XML.

If the file had an XML header that stated version 1.1, then you
could hold the characters with Unicode values < 32 (except null).
And relatively few parsers handle XML 1.1; that standard was a
non-starter.

But CDATA does not mean "can hold binary content". It's just a
wrapper that lets you avoid having to escape certain characters
such as < and &. The "C" means "character".

Typically when one needs to write binary content, it is exported as
base-64, as in the examples at http://www.stylusstudio.com/binary_xml.html

Hi Tony

I am getting the file as it is. Is the no character encoding for compressed binary data?

Regards
Brightman

There is none. XML is a text format.

In fact, to be considered a conforming XML parser, it *must*
reject binary data.

The definition of CDATA is here, and notice it refers to "Char"s
http://www.w3.org/TR/2008/REC-xml-20081126/#sec-cdata-sect

Clicking on the "Char" link gets us to a list of valid Unicode values,
[2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

The only valid values with a Unicode value >=0 and <=31 are TAB,
CR and LF.
