# Blockly Parser

Deserialize XML generated by the [Google Blockly](https://developers.google.com/blockly/) UI into data structures.

## Example usage:

```rust
extern crate blockly_parser;

use blockly_parser::{
    Program,
    StatementBody,
    Block,
    FieldValue,
    program_from_xml,
};

fn main() {
    let xml: &str = r#"
        <xml xmlns="http://www.w3.org/1999/xhtml">
            <variables></variables>
            <block type="main_loop" id="[.)/fqUYv92(mzb{?:~u">
