xmlparser

xmlparser is a low-level, pull-based, zero-allocation XML 1.0 parser.

Example

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

Why a new library

This library is basically a low-level XML tokenizer that preserves a position of the tokens and does not intend to be used directly. If you are looking for a more high-level solution - checkout roxmltree.

Benefits

• All tokens contain StrSpan objects which contain a position of the data in the original document.
• Good error processing. All error types contain position (line:column) where it occurred.
• No heap allocations.
• No dependencies.
• Tiny. ~1500 LOC and ~40KiB in the release build according to the cargo-bloat.
• Supports no_std builds. To use without the standard library, disable the default features.

Limitations

• Currently, only ENTITY objects are parsed from the DOCTYPE. Other 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 an XML like <item a="v1" a="v2"/> will be parsed without errors. You should check for this manually.
• UTF-8 only.

Safety

• The library must not panic. Any panic considered as a critical bug and should be reported.
• The library forbids the unsafe code.
