XML JSON, XML TO JSON

 The XML specification defines an XML document as a well-formed text, meaning that it satisfies a list of syntax rules provided in the specification. Some key points in the fairly lengthy list include:

 1. The document contains only properly encoded legal Unicode characters. 

 2. None of the special syntax characters such as < and & appear except when performing their markup-delineation roles. 

 3. The start-tag, end-tag, and empty-element tag that delimit elements are correctly nested, with none missing and none overlapping. 

 4. Tag names are case-sensitive; the start-tag and end-tag must match exactly. 

 5. Tag names cannot contain any of the characters !"#$%&'()*+,/;< = >?@[\]^`{|}~, nor a space character, and cannot begin with "-", ".", or a numeric digit. 

 6. A single root element contains all the other elements.
