Groovy 生成xml文件（使用MarkupBuilder）

上一篇介绍了如何使用Groovy解析xml文件，本文再介绍如何生成xml文件。与解析xml一样，Groovy也提供了两种方式MarkupBuilder和StreamingMarkupBuilder。一般而言StreamingMarkupBuilder更专业，功能更全。他们的区别有点类似于DOM和SAX， 也就说处理较大的xml文件，StreamingMarkupBuilder性能更好， 不过一般情况下，区别不大。 下面我们以MarkupBuilder为例。

代码

import groovy.xml.MarkupBuilder
    
    class XmlWriter {
        public static main(def args){
            def strXml = new StringWriter()
            MarkupBuilder mb  = new groovy.xml.MarkupBuilder(strXml);
    
            //mb.'?xml'(version:"1.0", encoding:"UTF-8")
            mb.interview{
                data{
                    person(id:"05891", comments:"social recruitment"){
                        title{
                            position(code:"P7","Staff SE")
                        }
                        age("29")
                        assessment(interviewer:"manager1", "tech is ok")
                        experience{
                            phase(from:"2012", to:"now", "CompanyA")
                            phase(from:"2010", to:"2012", "CompanyB")
                        }
                    }
    
                    person(id:"05892", comments:"campus recruitment"){
                        title{
                            position(code:"P6","SE")
                        }
                        age("25")
                        assessment(interviewer:"manager2", "tech is ok")
                        experience{
                            phase(from:"2012", to:"now", "UniversityA")
                            phase(from:"2011", to:"2012", "CompanyB")
                        }
                    }
                }
                interviewInfo{
                    date("2016-10-12")
                    address("meetingroom 402")
                    organizator(dept:"cloud","ZhangSan")
                }
            }
    
            print strXml
    
            def xmlFile = "output.xml"
            PrintWriter pw = new PrintWriter(xmlFile)
            pw.write(strXml.toString())
            pw.close()
    
        }
    }
