Question
Invalid characters in XML
Hi all,
I am developing an application using XML to talk with legacy backend (mainframe), some old mainframe application may use some invalid characters (e.g. low value x'00') such that when these characters are exist in the tag value, the xml parser will throw exception.
My question is, how many characters in XML are regarded as "invalid"? I've found some information in W3C (http://www.w3.org/TR/REC-
"
Character Range
[2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */
"
But I'm not quite understand for the above description. What is the corresponding Hex value ? Can anyone help to give me a brief explanation?
Thanks a lot!
