MathML Query Generator

Converts individual content MathML elements to equivalent XQuery statements in DB2 dialect.

The content MathML elements may be given as

1. MathWebSearch expressions,
2. annotation-xml elements with the attribute encoding="MathML-Content",
3. semantic elements, or
4. MathML tags that contain content MathML only

Details

If a document contains multiple elements, only the first MathWebSearch expression is processed.

If no MathWebSearch element is available, the first annotation-xml element will be used.

If no annotation-xml Math element is available, the first semantic element will be used.
