Examples

Basic Examples  (6)

Interpret MathML inputs:

Wolfram Language code: Interpreter["MathMLExpression"]["<math><mrow><mi>sin</mi><mo>&#8289;</mo><mo>(</mo><mi>x</mi><mo>)</mo></mrow></math>"]
Wolfram Language code: Interpreter["MathMLExpression"]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]

Restrict to a list of choices:

Wolfram Language code: Interpreter[Restricted["MathMLExpression", {{3, 4}}]]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["MathMLExpression", {{True, False}}]]["<math><mrow><mi>x</mi><mo>+</mo><msup><mi>&#8519;</mi><mi>y</mi></msup></mrow></math>"]

By default, all symbols are allowed. Restrict to a list of allowed symbols:

Wolfram Language code: Interpreter[Restricted["MathMLExpression", {Plus}]]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["MathMLExpression", {Plus}]]["<math><mrow><mn>2</mn><mo>*</mo><mn>2</mn></mrow></math>"]

By default, new symbols are created in $Context, but a custom context can be specified:

Wolfram Language code: var = Interpreter[Restricted["MathMLExpression", Automatic, Automatic, Automatic]]["<math><mrow><mn>x</mn></mrow></math>"] Context[Evaluate[var]]
Wolfram Language code: var = Interpreter[Restricted["MathMLExpression", Automatic, Automatic, "mycontext`"]]["<math><mrow><mn>x</mn></mrow></math>"] Context[Evaluate[var]]

Specify contexts for the allowed and output symbols:

Wolfram Language code: Global`x = 10; Interpreter[Restricted["MathMLExpression", Automatic, {"Global`", "System`"}, "Global`"]]["<math><mrow><mn>x</mn></mrow></math>"]

Prevent the creation of any new symbol:

Wolfram Language code: Interpreter[Restricted["MathMLExpression", Automatic, Automatic, None]]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["MathMLExpression", Automatic, Automatic, None]]["<math><mrow><mn>z</mn><mo>+</mo><mn>2</mn></mrow></math>"]
