//! This crate provides XML and DTD language support for the [tree-sitter][] parsing library. //! //! Typically, you will use the [LANGUAGE_XML][] constant to add this language to a //! tree-sitter [Parser][], and then use the parser to parse some code: //! //! ``` //! use tree_sitter::Parser; //! //! let code = r#" //! //! //! Tove //! Jani //! Reminder //! Don't forget me this weekend! //! //! "#; //! let mut parser = Parser::new(); //! let language = tree_sitter_xml::LANGUAGE_XML; //! parser //! .set_language(&language.into()) //! .expect("Error loading XML parser"); //! let tree = parser.parse(code, None).unwrap(); //! assert!(!tree.root_node().has_error()); //! ``` //! //!
