[API documentation](https://docs.rs/xml5ever)

**Warning:** This library is alpha quality, so no guarantees are given.

This crate provides a push based XML parser library that trades well-formedness for error recovery.

xml5ever is based largely on [html5ever](https://github.com/servo/html5ever) parser, so if you have experience with html5ever you will be familiar with xml5ever.

The library is dual licensed under MIT and Apache license.

# Why you should use xml5ever

Main use case for this library is when XML is badly formatted, usually from bad XML
templates. XML5 tries to handle most common errors, in a manner similar to HTML5.

## When you should use it?

  - You aren't interested in well-formed documents.
  - You need to get some info from your data even if it has errors (although not all possible errors are handled).
  - You want to features like character references or XML namespaces.

## When you shouldn't use it

  - You need to have your document validated.
  - You require DTD support.
  - You require an easy to use parser, with lots of extensions (e.g. XPath, XQuery).
  - You require a battle tested, industry proven solution.

# Installation

Add xml5ever as a dependency in your project manifest:

```toml
    [dependencies]
    xml5ever = "0.18"
```

# Getting started

Here is a very simple RcDom backed parser:

```rust

    let input = "<xml></xml>".to_tendril();

    // To parse XML into a tree form, we need a TreeSink
    // luckily xml5ever comes with a static RC backed tree represetation.
    let dom: RcDom = parse(std::iter::once(input), Default::default());

    // Do something with dom

```
The thing that does actual parsing is the `parse` function. It expects an iterator that can be converted into `StrTendril`, so you can use `std::iter::once(input)` or  `Some(input).into_iter()` (where `input` is `StrTendril` like structure).

# Working on xml5ever

To build examples and tests you need to do something along the lines of:

```rust
    git submodule update --init # to fetch xml5lib-tests
    cargo build
    cargo test
```

This will fetch tests from outside repository and it will invoke cargo to
build and test the crate. If you need docs checkout either [API docs](https://docs.rs/xml5ever) or run `cargo docs`
to generate documentation.
