Represent space and tab in XML tag

Question

How to represent space and tab in XML tag  Is there any special characters for them to represent

User · Answer

I think you could use an actual space or tab directly in XML document  but if you are looking for special characters to represent them so that text processors can t mess them up  then it s   space    amp  032  tab      amp  009

If you are talking about the issue where multiple and non-space whitespace characters are stripped specifically from attribute values  then yes  encoding them as character references such as  amp  9  will fix it

Illegal XML Tag Name Characters can be encoded using Unicode UCS-2  This works very nicely  I am using it to create XML that gets turned into json  JPath is weak compared to XPath   Notice the handling of spaces       characters  Unicode UCS-2 Code Chart  http   www columbia edu kermit ucs2 html          tag Name   tag Name Replace        x005F x0020             tag Name   tag Name Replace        x005F x0028             tag Name   tag Name Replace        x005F x0029       XML      lt Internal x005F x0020 Chargeback x005F x0020 ID gt  CHARGEBACKCODE  lt  Internal x005F x0020 Chargeback x005F x0020 ID gt     lt Bill x005F x0020 To gt  CHARGEBACKCODE  lt  Bill x005F x0020 To gt     lt Operator x005F x0020 or x005F x0020 Directly x005F x0020 Responsible x005F x0020 Individual x005F x0020  x005F x0028 DRI x005F x0029  gt zzz yyy gov lt  Operator x005F x0020 or x005F x0020 Directly x005F x0020 Responsible x005F x0020 Individual x005F x0020  x005F x0028 DRI x005F x0029  gt    transformed to json via json net        Internal Chargeback ID     CHARGEBACKCODE         Bill To     CHARGEBACKCODE         Operator or Directly Responsible Individual  DRI     xxx yyy gov

You cannot have spaces and tabs in the tag  i e   name  of an XML elements  see the specs  http   www w3 org TR REC-xml  NT-STag  Beside alphanumeric characters  colon  underscore  dash and dot characters are allowed in a name  and the first letter cannot be a dash or a dot  Certain unicode characters are also permitted  without actually double-checking  I d say that these are international letters
