Rust wrapper for [libxml2](http://xmlsoft.org/).
The main goal of this project is to benefit from libxml2's maturity and stability while the native Rust XML crates mature to be near-drop-in replacements.
As of the `0.2.0` release of the crate, there are some modest safety guarantees:
* Mutability, as well as ownership - we use `Rc<RefCell<T>>` wrappers to ensure runtime safety of libxml2 operations already in the Rust layer.
* Memory safety guarantees - in particular `Node` and `Document` objects have automatic bookkeeping and deallocation on drop, for leak-free wrapper use.
* No thread safety - libxml2's global memory management is a challenge to adapt in a thread-safe way with minimal intervention
**Coverage**: Only covers a subset of libxml2 at the moment, contributions are welcome. We try to increase support with each release.
**Welcome!** With these caveats, the contributors to the project are migrating production work towards Rust and find a continuing reliance on libxml2 a helpful relief for initial ports. As such, contributions to this crate are welcome, if your workflow is not yet fully supported.
## Installation prerequisites
Before performing the usual cargo build/install steps, you need to have the relevant components for using the original libxml2 code. These may become gradually outdated with time - please do let us know by opening a new issue/PR whenever that's the case.
### Linux/Debian
On linux systems you'd need the development headers of libxml2 (e.g. `libxml2-dev` in Debian), as well as `pkg-config`.
### MacOS
[Community contributed](https://github.com/KWARC/rust-libxml/issues/88#issuecomment-890876895):
```
$ brew install libxml2 # e.g. version 2.9.12
$ ln -s /usr/local/Cellar/libxml2/2.9.12/lib/libxml2.2.dylib /usr/local/lib/libxml-2.0.dylib
$ export LIBXML2=/usr/local/Cellar/libxml2/2.9.12/lib/pkgconfig/libxml-2.0.pc
```
### Windows
[Community contributed](https://github.com/KWARC/rust-libxml/issues/81#issuecomment-760364976):
* manually install builds tools c++ and english language by visiting [BuildTools](https://visualstudio.microsoft.com/fr/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16)
* launch cmd prompt with admin privileges and execute these commands sequentially:
```
C:\> git clone https://github.com/microsoft/vcpkg
C:\> .\vcpkg\bootstrap-vcpkg.bat
C:\> setx /M PATH "%PATH%;c:\vcpkg" && setx VCPKGRS_DYNAMIC "1" /M
C:\> refreshenv
C:\> vcpkg install libxml2:x64-windows
C:\> vcpkg integrate install
```
