Layer7 API Management

I need to convert the below JSON to XML 

{"bookstore":{"1234":["abc","xyz","lhvl"],"2345":["abc","xyz","lhvl"]}}

but i am getting error saying "Converted XML is invalid.  The content of elements must consist of well-formed character data or markup."

The same when i try converting using few online JSON to XML converters works fine.What could be the issue?

Hi Sonalee,

It looks like this is failing as it is not adhering to XML element naming:

XML elements must follow these naming rules:

Names can contain letters, numbers, and other characters
Names cannot start with a number or punctuation character
Names cannot start with the letters xml (or XML, or Xml, etc)
Names cannot contain spaces
