How to create xml root tag which starts with digit in java using DOM pareser

<6tag>
  <abc>1</abc>
  <cde>2</cde>
</6tag>

Answer 1

XML tag names should not begin with a digit, but may contain a digit.

[4]     NameStartChar ::=   ":" | [A-Z] | "_" | [a-z] | 
                        [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | 
                        [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | 
                        [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | 
                        [#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

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

[5]     Name       ::=      NameStartChar (NameChar)*

Answer 2

The Java XML standards discourage the use of numbers in XML tags, probably because of software compatibility. However, they are legal to use, but not as a first character, as I read at the W3School .
