How to include space in XML tag/element which gets transformed by XSLT into Excel sheet [duplicate]

Answer 1

How to I incorporate space in an XML tag/element? I tried putting or %20 or  etc etc . (all kinds of syntax) but all of them shows error on xml editor itself saying this hexadecimal character is not allowed

You can't. The W3C XML specification strictly defines the syntax of names. A name can only start with a letter character (this includes underscore), then the next characters can be letter characters or numbers or the hyphen, but the space is a delimiter and is not allowed as part of any name.

More precisely, here are the exact rules from the spec:

[4a]    NameChar    ::=    NameStartChar | "-" | "." | [0-9] | #xB7 | [#x0300-#x036F] | [#x203F-#x2040] 
[5]    Name    ::=    NameStartChar (NameChar)* 

To overcome this restriction you have to modify your XSLT transformation so that it outputs as Excel column names more convenient to read strings than XML names.
