You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: loader_html.rs
    path of file: ./repos/rbatis/tests
    
    the code of the file until where you have to start completion: #[cfg(test)]
mod test {
    use rbatis_codegen::codegen::loader_html::load_html;

    #[test]
    fn test_parser() {
        let nodes = load_html(r#"<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "https://raw.githubusercontent.com/rbatis/rbatis/master/rbatis-codegen/mybatis-3-mapper.dtd">
<mapper>
    <insert id="insert">
        'insert into biz_activity'
        <foreach collection="arg" inde
    
    fn test_parser() {
        let nodes = load_html(r#"<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "https://raw.githubusercontent.com/rbatis/rbatis/master/rbatis-codegen/mybatis-3-mapper.dtd">

            '${key}'
        </foreach>
        'values'
        <foreach collection="arg" index="key" item="item" open="(" close=")" separator=",">
            '${item}'

        println!("{:?}", nodes);
    }
