如何使用Groovy从XML文件提取HTML代码

Question

我有这个XML文件，我需要从“ mono”元素中提取HTML代码，但是我需要html标签。 我需要使用groovy编程语言。

“ mono”元素中的所有div都是HTML标记，包括div

先感谢您。

<dataset>
    <chapters>
        <chapter id="700" name="Immunology">
            <title>Immunology</title>   
            <monos>
                <mono id="382727">

                    <div>
                        <h1>blah blah</h1>
                    </div>
                    <div>
                        <p>blah blah</p>
                    </div>

            </mono>
            </monos>
        </chapter>  
        <chapter id="701" name="hematology">
            <title>Inmuno Hematology</title>    
            <monos>
                <mono id="blah blah">
                    <div>
                        <h1>blah blah</h1>
                    </div>
                    <div>
                        <div class="class1">blah blah</div>
                    </div>
                </mono>
            </monos>
        </chapter>
    </chapters>
</dataset>

我努力了 ：

import javax.xml.parsers.*;

xml = new XmlParser().parse("languages.xml")

println("There are " +xml.chapters.chapter.size() +" Chapters")

for (int i = 0; i < xml.chapters.chapter.size(); i++) {

            def chapter = xml.chapters.chapter[i]
            def chapterName = chapter.'@name'
            println chapterName

            println("----  Monos List ----\n\n")


            for (int j = 0; j < chapter.monos.mono.size(); j++) {

                        def mono = chapter.monos.mono[j]
                        println("Mono Content: " + mono.toString());
            }

           println("---- End Monos List ----\n\n")

}

但是我得到以下输出：

免疫学分为两章---- Monos列表----

单声道内容：mono [attributes = {id = 382727}; 值= [DIV [属性= {}; 值= [H1 [属性= {}; value = [blah blah]]]]，div [attributes = {}; 值= [P [属性= {}; 值= [blah blah]]]]]] ----结束Monos列表----

血液学---- Monos列表----

单声道内容：mono [attributes = {id = blah blah}; 值= [DIV [属性= {}; 值= [H1 [属性= {}; value = [blah blah]]]]，div [attributes = {}; 值= [DIV [属性= {类= Class1的}; 值= [blah blah]]]]]] ----结束Monos列表----

您可以使用XmlSlurper或XmlParser解析xml内容。

import groovy.xml.*
def RECORDS = '''

                            <div>

def monos = records.depthFirst().findAll{ it.name().equals('mono') }

输出：
