*htmlparser* is a low-level, pull-based, zero-allocation HTML parser.

<br>

## Example

```rust
for token in htmlparser::Tokenizer::from("<tagname name='value'/>") {
    println!("{:?}", token);
}
```

<br>

## Why a new library?

This library is basically a low-level XML tokenizer that preserves the
positions of the tokens and is not intended to be used directly.

This library is a copy of [xmlparser](https://crates.io/crates/xmlparser) with some adjustments
to parse html.

<br>

## Benefits

- All tokens contain `StrSpan` structs which represent the position of the
  substring in the original document.
- Good error processing. All error types contain the position (line:column)
  where it occurred.
- No heap allocations.
- No dependencies.
- Tiny. ~1400 LOC and ~30KiB in the release build according to
  `cargo-bloat`.
- Supports `no_std` builds. To use without the standard library, disable the
  default features.

<br>

## Limitations

- Currently, only ENTITY objects are parsed from the DOCTYPE. All others are
  ignored.
- No tree structure validation. So an XML like
  `<root><child></root></child>` or a string without root element will be
  parsed without errors. You should check for this manually. On the other
  hand `<a/><a/>` will lead to an error.
- Duplicated attributes is not an error. So XML like `<item a="v1" a="v2"/>`
  will be parsed without errors. You should check for this manually.
- UTF-8 only.

<br>

## Safety

- The library must not panic. Any panic is considered a critical bug and
  should be reported.
- The library forbids unsafe code.
