Crate xrust[−][src]
Expand description
A Rust implementation of the XQuery and XPath Data Model 3.1.
The library separates parsing from evaluation. An expression is compiled to create a ‘Sequence Constructor’. This constructor is then applied to a source document to produce a Sequence.
A Sequence is an ordered collection of zero or more Items, implemented as a Rust Vector. An Item is a Node, Function or atomic Value.
See the graphitem module for an example of how to evaluate an XSL stylesheet.
Status
The project, so far, is a proof-of-concept.
For XPath it provides most of v1.0 functionality, with some v2.0 and v3.1 features.
For XSLT, the implementation has barely started. To begin with it only supports literal result elements and literal text.
The library has not been extensively tested.
Plan
- Implement a v3.1 XSLT engine.
Goals / Future Work
- The library should always return errors, i.e. it should not panic
- Make the library more idiomatically Rust
