如何使用groovy从XML文件中提取HTML代码

Question

我有这个XML文件，我需要从"mono“元素提取HTML代码，但我需要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

提前谢谢你。

<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>

我试过了：

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")

}

但我只得到了以下输出：

有2章免疫学- Monos列表

单声道内容: mono[attributes={id=382727}；value=[div[attributes={}；value=[h1[attributes={}；value=blah blah]，div[attributes={}；value=[p[attributes={}；value=blah blah]- End Monos List

血液学- Monos列表

单声道内容: mono[attributes={id=blah blah}；value=[div[attributes={}；value=[h1[attributes={}；value=blah blah]，div[attributes={}；value=[div[attributes={class=class1}；value=blah blah]- End Monos List

您可以使用XmlSlurper或XmlParser来解析xml内容。

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

                </monos>

                        <mono id="blah blah">
                            <div>
                                <h1>blah blah</h1>
                            </div>

                </chapter>
            </chapters>

  '''
def records = new XmlSlurper().parseText(RECORDS)
def monos = records.depthFirst().findAll{ it.name().equals('mono') }
assert monos[0].toString() == "blah blahblah blah";

输出：
