The following analysis refers to the Document Object Model (DOM) specification.
XML elements (also known as tags) can be definitely considered containers, so we can reuse both the rdf:Property component for specifying tag attributes, and container membership properties for specifying relations to child elements in the DOM tree.
These may include text, which are expressed as RDF literals of type xsd:string.
Tag names are represented as RDF types: rdf:type.
SPARQL Anything reuses namespaces declared within the original document to name properties and types, when available, otherwise fallbacks to the default xyz:.
!!! note XML attribute values are always interpreted as literals, even if they are supposed to be QName in a referred XML schema. See also this comment.
SPARQL Anything selects this transformer for the following file extensions:
- svg
- svgz
- xml
SPARQL Anything selects this transformer for the following media types:
- application/xml
- image/svg+xml
- text/xml
