OxRdfXml is a parser and serializer for [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/).

The entry points of this library are the two [`RdfXmlParser`] and [`RdfXmlSerializer`] structs.

Usage example counting the number of people in a RDF/XML file:

```rust
use oxrdf::{NamedNodeRef, vocab::rdf};
use oxrdfxml::RdfXmlParser;

fn main() {
    let file = br#"<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:schema="http://schema.org/">
 <rdf:Description rdf:about="http://example.com/foo">
   <rdf:type rdf:resource="http://schema.org/Person" />
   <schema:name>Foo</schema:name>
 </rdf:Description>
 <schema:Person rdf:about="http://example.com/bar" schema:name="Bar" />
</rdf:RDF>"#;

    let schema_person = NamedNodeRef::new("http://schema.org/Person").unwrap();
    let mut count = 0;
    for triple in RdfXmlParser::new().parse_read(file.as_ref()) {
        let triple = triple.unwrap();
        if triple.predicate == rdf::TYPE && triple.object == schema_person.into() {
            count += 1;
        }
    }
    assert_eq!(2, count);
}
```
