Scheme XML loader for webpack.
**NOTE**:
At the moment, the _sxml-loader_ only works with
[Chicken Scheme](http://call-cc.org/) and its
[sxml-serializer](http://wiki.call-cc.org/eggref/5/sxml-serializer)
egg, so you need to install them in order to use the _sxml-loader_.
Usage
-----
**SXML**:
```scm
'(h1 "Hello")
```
_See the full example in the [example](example) directory._

By default SXML will be processed by _Chicken Scheme_
with _sxml-serializer_ egg. You can use a different interpreter
by setting the loader options.
GNU Guile example:
```js
// ...
use: [
'html-loader',
{
loader: 'sxml-loader',
options: {
interpreter: 'guile',
flags: ['-c'], // "eval" flag (in Guile case "-c") should be last.
// SXML_LOADER_CONTENT will be replaced with processing SXML markup.
expr: '(use-modules (sxml simple))(sxml->xml SXML_LOADER_CONTENT)',
},
},
],
// ...
```
