Is  a valid character in XML?

Question

On this data:

<row Id="37501" PostId="135577" Text="...uses though.&#x10;"/>

I'm getting an error with the Python sax parser:

xml.sax._exceptions.SAXParseException:
comments.xml:29776:332: reference to invalid character number

I trimmed the example; 332 points to "".

Is the parser correct in rejecting this character?

Answer 1


 is the linefeed character, which seems to be the intent.

 would be the same as  (10 hex is 16 decimal) and would refer to the DLE (data link escape) character.

DLE is a transmission control character used to control the interpretation of data being transmitted.

Answer 2

As others have stated, you probably meant 
. The reason why  (0x10 = 10h = 16) is invalid is that it's explicitly excluded by the XML 1.0 standard: (http://www.w3.org/TR/xml/#NT-Char)

Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
