# libxml2
4+
5+
This is [libxml2](https://gitlab.gnome.org/GNOME/libxml2), packaged for [Zig](https://ziglang.org/).
6+
7+
## Installation
8+
9+
First, update your `build.zig.zon`:
10+
11+
```
12+
# Initialize a `zig build` project if you haven't already
13+
zig init
14+
zig fetch --save git+https://github.com/allyourcodebase/libxml2.git
15+
```
16+
17+
You can then import `libxml2` in your `build.zig` with:
18+
19+
```zig
20+
const libxml2_dependency = b.dependency("libxml2", .{
21+
.target = target,
22+
.optimize = optimize,
23+
.iconv = false, // This would link to `libiconv` otherwise
24+
});
25+
your_exe.linkLibrary(libxml2_dependency.artifact("libxml2"));
26+
```
