It's not an XML parser since it does not only split the content into the XML nodes, but also supports [SVG types](https://www.w3.org/TR/SVG/types.html#BasicDataTypes) parsing. ### Supported SVG types - [\<color\>](https://www.w3.org/TR/SVG/types.html#DataTypeColor) - [\<paint\>](https://www.w3.org/TR/SVG/painting.html#SpecifyingPaint) - [\<path\>](https://www.w3.org/TR/SVG/paths.html#PathData) - [\<number\>](https://www.w3.org/TR/SVG/types.html#DataTypeNumber) and \<list-of-numbers\> - [\<length\>](https://www.w3.org/TR/SVG/types.html#DataTypeLength) and \<list-of-lengths\> - [\<coordinate\>](https://www.w3.org/TR/SVG/types.html#DataTypeCoordinate) - [\<IRI\>](https://www.w3.org/TR/SVG/types.html#DataTypeIRI) - [\<FuncIRI\>](https://www.w3.org/TR/SVG/types.html#DataTypeFuncIRI) - [\<transform-list\>](https://www.w3.org/TR/SVG/types.html#DataTypeTransformList) - [\<style\>](https://www.w3.org/TR/SVG/styling.html#StyleAttribute) ### Benefits - Most of the common data parsed into internal representation, and not just as string (unlike typical XML parser). Tag names, attribute names, attributes value, etc. - Complete support of paths, so data like `M10-20A5.5.3-4 110-.1` will be parsed correctly. - [Predefined SVG values](https://www.w3.org/TR/SVG/propidx.html) for presentation attributes, like `auto`, `normal`, `none`, `inherit`, etc. are parsed as `enum`, not as `String`. - Every type can be parsed separately, so you can parse just paths or transform or any other SVG value. - Good error processing. All error types contain position (line:column) where it occurred. - No heap allocations. - Pretty fast. ### Limitations - All keywords must be lowercase. Case-insensitive parsing is supported only for color names. Still, it's extremely rare. - The `<color>` followed by the `<icccolor>` is not supported. As the `<icccolor>` itself. - Only ENTITY objects are parsed from the DOCTYPE. Other ignored. - CSS styles does not processed. You should use an external CSS parser. - Comments inside attributes value supported only for the `style` attribute. - [System colors](https://www.w3.org/TR/css3-color/#css2-system), like `fill="AppWorkspace"`, are not supported. - There is no separate `opacity-value` type. It will be parsed as `<number>`, but will be bound to 0..1 range. - Implicit path commands are not supported. All commands are parsed as explicit. - Implicit MoveTo commands will be automatically converted into explicit LineTo. ### Safety - The library should not panic. Any panic considered as a critical bug and should be reported. - The library forbids unsafe code. */ #![doc(html_root_url = "https://docs.rs/svgparser/0.6.0")] #![forbid(unsafe_code)] #![warn(missing_docs)] pub extern crate xmlparser; extern crate phf; #[macro_use] extern crate log; #[macro_use] extern crate error_chain; macro_rules! try_opt { ($expr: expr) => { match $expr { Some(value) => value, None => return None } } } pub mod path; pub mod style; pub mod svg; pub mod transform; mod attribute_id; mod attribute_value; mod color; mod colors; mod element_id; mod error; mod length; mod streamext; mod value_id; mod values_list; pub use attribute_id::{ AttributeId, }; pub use attribute_value::{ AttributeValue, PaintFallback, }; pub use color::{ Color, }; pub use element_id::{ ElementId, }; pub use error::{ ChainedErrorExt, Error, ErrorKind, }; pub use length::{ Length, LengthUnit, }; pub use streamext::{ StreamExt, }; pub use value_id::{ ValueId, }; pub use values_list::{ NumberList, LengthList, }; pub use xmlparser::{ ChainedError, EntityDefinition, ErrorPos, ExternalId, FromSpan, Stream, StrSpan, TextUnescape, XmlSpace, };
