Basic Examples  (1)

Wolfram Language code: Needs["XML`"]

A SymbolicXML expression with one small error:

Wolfram Language code: symbolicXMLWithError = XMLElement["math", {"xmlns" -> "http://www.w3.org/1998/Math/MathML"}, {XMLElement["semantics", {}, {XMLElement["msup", {}, {XMLElement["mi", {}, {"x"}], XMLElement["mn", {"2"}]}], XMLElement["annotation-xml", {"encoding" -> "MathML-Content"}, {XMLElement["apply", {}, {XMLElement["power", {}, {}], XMLElement["ci", {}, {"x"}], XMLElement["cn", {"type" -> "integer"}, {"2"}]}]}]}]}];

SymbolicXMLQ indicates that there is an error:

Wolfram Language code: SymbolicXMLQ[symbolicXMLWithError, True]

SymbolicXMLErrors returns a part specification indicating where the error occurred, and a message indicating the nature of the problem:

Wolfram Language code: SymbolicXMLErrors[symbolicXMLWithError]

The XMLElement only has two arguments—the list for the attributes is missing:

Wolfram Language code: symbolicXMLWithError[[3, 1, 3, 1, 3, 2]]
