html 试题试卷(包含latex)下载成word

 

主要目的:

  • 分享将带latex的html格式的试题试卷以word的格式下载,并且加一些灵活的排版样式
  • 接受群众的检阅,获得反馈
  • 骗取打赏,或者github star

需求背景:

  • html 混有latex公式的试题组成的试卷,下载成为word格式
  • word试卷的排版,纸张大小,字体,密封线,标题,题型,誉分栏等
  • html 呈现的样式和word呈现的样式一致(只能大体一致,有些样式还是没做到完全一致)

方案概要:

       主要方案:提取HTML里的题文内容 >> 转换为word标签样式 >> (制造试卷模板)将转换成word样式的题文填充到模板中 >> 组建word(doc 或 docx)

  • 制作freemark模板: 编辑好doc和docx的样板试卷,将其转化为xml格式,再转为ftl文件,并根据排版需求编写填充逻辑
  • 编写调用freemark下载程序:根据传入条件选择doc或docx模板下载
  • 解析html试题内容:用XPath分解试题内容,提取样式,将信息结构化
  • 将结构化的试题内容翻译为word标签格式:将html样式翻译为对应的word里面的标签格式,让其可以填充到freemark模板中而不违背word标签的语法规范
  • 综合以上步骤就可以将HTML格式的试卷下载为word格式的,文末会附源码

提前需要了解的知识:

  • freemark相关语法知识
  • XPath相关基础知识
  • html标签样式相关知识
  • word标签样式相关知识

详细实现步骤:

 freemark模板制作:

1.  根据需求制作全样式的试卷样板(doc,docx 各一份)[例图:A3全样式模板]

说明:包含需求所有样式(字体,密封线,标题,题型,誉分栏等),后续在编写模板显示逻辑时可以灵活控制是否生效

2.  将doc,docx 格式的样板转换为xml

doc格式的将文件另存为  Word XML 文档(*.xml) 格式,用Notepad++等类似更具打开(NotePad++中安装XML Tools 插件,这个可以格式化xml文件,对后续的工作用处很大)[例图,折叠起来,大体结构如下]

 

1).word xml 结构的简单介绍(纯属个人猜想,不是官方定义,如果想了解详细的结构找正规的介绍资料),下面只介绍我们用到的部分

· pkg:part:/word/_rels/document.xml.rels :用于定义header(页眉),footer(页脚),styles(样式),image(图片)等pkg:part的引用

说明:页眉,页脚可以定义多个,需要在word中展示的图片路径和引用在此定义

· pkg:part:/word/document.xml :正文部分,word中呈现的除页眉页脚以外的主要内容都在此部分(最重要的部分,后面介绍里面的格式)

· pkg:part:/word/footer.xml :页脚部分,设置试卷第几页,共几页

· pkg:part:/word/header.xml :页眉部分,设置试卷密封线

· pkg:part:/word/styles.xml :样式,设置默认字体等

· pkg:part:/word/media/image.png:图片内容(base64),docx中将图片放在/word/media文件夹下

docx 格式的样板,用解压工具解压开(不要惊讶,没写错就是解压开,docx 是一种压缩文件,它是将原本的doc的xml中的每个结构块拆开成独立文件压缩而成的)[例图:样例文件结构如下]

 

 word文件夹下文件

 

docx的结构大致如将doc中每个pkg:part单独拆成文件,放在一定结构的文件夹下,最后压缩而成的,每块的功能和doc的相应pkg:part一样

docx有的[Content_Types].xml文件:定义图片类型,和其他pkg:part

 正文部分:/word/document.xml 用到的标签简单介绍:

1>段落:<w:p> :段落;<w:pPr>:段落样式;<w:r>:内容部分;<w:rPr>:内容样式;<w:t>:文字内容

<w:p w:rsidR="004D42A0" w:rsidRDefault="005F1054">
    <w:pPr>
        <w:jc w:val="center"/>
        <w:rPr>
            <w:rFonts w:eastAsia="黑体"/>
            <w:b/>
            <w:sz w:val="30"/>
            <w:szCs w:val="30"/>
        </w:rPr>
    </w:pPr>
    <w:r w:rsidRPr="00771D19">

        </w:rPr>
        <w:t>学年</w:t>
    </w:r>
</w:p>

2>图片:<w:pict>:图片标签;<v:shape>:图片样式;<v:imagedata>:引入图片(根据/word/_rels/document.xml.rels定义的图片id)

            <w:r>
                <w:pict>
                    <v:shape id="_x0000768de9d0ea6111e98c2a28843b052b2f" type="_x0000_t75" style="width:85pt;height:43pt">
                        <v:imagedata r:id="rId768de9d0ea6111e98c2a28843b052b2f" o:title="2"/>

以上就是word试卷样板和word结构和标签的简单介绍,这写对于生成word很重要,涉及的内容也比较多,本人了解的也不多,是一个个试出来的,如有其它需求大家可以查文档或通过控制变量的方式,打开word编辑出自己想要的样式转成xml和原版xml对比找出不同的部分锁定样式设置的地方

 

2.  将xml样板转换为freemark的ftl模板

1).doc的xml文件直接将后缀改为.ftl,并将模板中的过多信息删除(每个后期填充的图片,段落样式保持一个),做到最精简的模板,放入项目中

2).docx的xml文件将 /word/document.xml 正文部分取出,如果页眉页脚样式也会有灵活变化也可以取出来做成模板,放入项目中

               

3).编写数据填充逻辑(得有一定基础的freemark语法基础)

doc模板的数据填充逻辑编写描述:

1>:图片引用编写:在/word/_rels/document.xml.rels 部分,动态引入图片链接,同时图片的base64也应该引到pkg:part 里

<pkg:part pkg:name="/word/_rels/document.xml.rels" pkg:contentType="application/vnd.openxmlformats-package.relationships+xml" pkg:padding="256">
    <pkg:xmlData>
        <Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
            <Relationship Id="rId8" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/header" Target="header2.xml"/>
             ..........
            <#list relations.relationshipStr as rs> 
                    ${rs} 
            </#list> 
        </Relationships>
    </pkg:xmlData>
</pkg:part>

2>:题文内容填充:在/word/document.xml部分

<w:p w:rsidR="00C93DDE" w:rsidRPr="00771D19" w:rsidRDefault="00BF47F0" w:rsidP="00C93DDE">
    <w:pPr>
        <w:jc w:val="center"/>
        <w:rPr>
            <w:rFonts w:eastAsia="黑体"/>
            <w:b/>
            <w:sz w:val="30"/>
            <w:szCs w:val="30"/>
        </w:rPr>
    </w:pPr>
    <w:r w:rsidRPr="00771D19">
        <w:rPr>
            <w:rFonts w:eastAsia="黑体" w:hint="eastAsia"/>
            <w:b/>
            <w:sz w:val="30"/>
            <w:szCs w:val="30"/>
        </w:rPr>
        <w:t>${(mainTitle.mainTitleName)!'XXXX学年度XX学校XX考试'}</w:t>
    </w:r>
</w:p>

<#list questionsList as qMap>
    <w:p w:rsidR="00A81065" w:rsidRDefault="00BF47F0" w:rsidP="00744A41">
        <w:pPr>
            <w:pStyle w:val="a7"/>
            <w:ind w:firstLineChars="0"/>
            <w:textAlignment w:val="center"/>
            <w:spacing w:line="360" w:lineRule="auto"/>
        </w:pPr>
    ${(qMap.questionContent)!""}
    </w:p>
</#list>

基本就是些if,else,循环list的操作就可以满足基本的需求,不再列举,只要找到正确样式和样式位置就可以完成

  根据freemark模板下载word程序编写:

1.  引入freemarker jar包

<dependency>
    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.26-incubating</version>
</dependency>

2.  模板读取

public class PaperDownloadSeting {
    private static Configuration configuration = null;
    private static Map<String, Template> allTemplate = null;
    private static Logger logger= LoggerFactory.getLogger(PaperDownloadSeting.class.getName());
    static{
        configuration = new Configuration(Configuration.VERSION_2_3_0);
        configuration.setDefaultEncoding("UTF-8");
        configuration.setClassForTemplateLoading(PaperDownloadSeting.class, "/freemarkmould/papermould/");
        allTemplate = new HashMap<String,Template>();
        try{
            allTemplate.put("docmould", configuration.getTemplate("docmould.ftl"));
            allTemplate.put("docxDocumentMould", configuration.getTemplate("docxmould/document.ftl"));
            allTemplate.put("docxHeader1Mould", configuration.getTemplate("docxmould/header1.ftl"));
            allTemplate.put("docxHeader2Mould", configuration.getTemplate("docxmould/header2.ftl"));
            allTemplate.put("docxStylesMould", configuration.getTemplate("docxmould/styles.ftl"));
        }catch(IOException e){
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

3.  数据填充,word流生成

    /**
     *@Desc: 获取word文件流,paperMap:处理成word样式的试卷信息,out:word输出流
     */
    public  static void getwordFileOutPutStream(Map<String, Object> paperMap,String docType, OutputStream out){
        try{
            Writer w = new OutputStreamWriter(out,"utf-8");
            if(docType.equals("doc")) {
                Template t = allTemplate.get("docmould");
                t.process(paperMap,w);//freemark向模板填充数据
                w.close();
                deleteTmpImages(paperMap.get("tempMediaPath").toString());
            }
            if(docType.equals("docx")) {
                ZipOutputStream zipout = new ZipOutputStream(out);
                zipdocx(paperMap,zipout);
            }
        }catch(Exception e){
            e.printStackTrace();
            throw new RuntimeException(e);
        }finally {
            try {
                out.close();
                deleteTmpImages(paperMap.get("tempMediaPath").toString());
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
    }

    /**

到此我们就可以将文本的简单数据填充到模板,并下载成word了,接下来我们要做的就是将html格式的试题转换为相应的word格式,填充到模板

 

   解析html试题内容,将其结构化:

1.  引入XPath jar包

<dependency>
    <groupId>cn.wanghaomiao</groupId>
    <artifactId>JsoupXpath</artifactId>
    <version>2.2</version>
</dependency>

2.  解析HTML试题内容

    private String childStr;
    private String nodeParent;
    private  List<Node> childNodeList;

        return nodeName;
    }

    public void setNodeName(String nodeName) {
        this.nodeName = nodeName;

        this.attrMap = attrMap;
    }

        return nodeText;
    }

    public void setNodeText(String nodeText) {
       // nodeText=nodeText.replaceAll("[\n\r\t]","");
        nodeText=nodeText.trim();
        if(nodeText==null||nodeText.equals("")) {nodeText=null;}
        this.nodeText = nodeText;
    }

    public String getNodeStr() {
        return nodeStr;
    }

    public void setNodeStr(String nodeStr) {
        nodeStr=nodeStr.replaceAll("[\n\r\t]","");
        this.nodeStr = nodeStr;
    }

    public String getChildStr() {
        return childStr;
    }

    public void setChildStr(String childStr) {
        this.childStr = childStr;

        this.nodeParent = nodeParent;
    }

    public List<Node> getChildNodeList() {
        return childNodeList;
    }

    public void setChildNodeList(List<Node> childNodeList) {
        this.childNodeList = childNodeList;
    }
}

 以上代码就可以将html的题文结构化,接下来我们将这个结构化的题文翻译成word格式

 

   将结构化的题文翻译为word格式:

这块的代码比较多,写的也不好,就不粘了,大家可以看下我的源码看(看  com\pdl\paperdownload\wordpapermake\htmltowordhandle 下面的类就行),简单介绍一下这块的内容:

1. 将结构化的题文里的每个node 解析成word的格式,得自己总结HTML样式和word样式的对应关系

下面简单列举几个对应样式:

· 下面绿色部分为word段落样式设置位置;黄色部分为内容样式设置位置

<w:p w:rsidR="00A81065" w:rsidRDefault="00BF47F0">
    <w:pPr>
        <w:ind w:leftChars="130" w:left="273"/>
        <w:textAlignment w:val="center"/>
        <w:spacing w:line="360" w:lineRule="auto"/>
    </w:pPr>
    <w:r w:rsidRPr="00043B54">
        <w:t xml:space="preserve"> 【解析】</w:t>
    </w:r>
    <w:r>
        <w:rPr>
            <w:rFonts w:hint="eastAsia"/>
            <w:b/>
        </w:rPr>
        <w:t>试题分析</w:t>
    </w:r>
</w:p>

· 居中:word段落样式

<w:jc w:val="center"/>

 · 首行缩进:word段落样式

<w:ind w:firstLineChars="200" w:firstLine="480"/>

· 右对齐:word段落样式

<w:jc w:val="right"/>

 · 加粗:内容样式

<w:b/>

· 斜体:内容样式

<w:i/>

· 下划线:内容样式

<w:u w:val="single"/>

· 允许内容中的空格显示设置(绿色部分为设置部分)

<w:r>
    <w:t xml:space="preserve"> hello pretty girl!</w:t>
</w:r>

· 上下标 sub sup:内容样式

<w:vertAlign w:val="superscript"/>

<w:vertAlign w:val="subscript"/>

 

 其他格式:

 · omml 公式放在<w:p>段落标签里面(关于latex转换为word公式omml的方法,可以看我的另一篇分享:https://www.cnblogs.com/maoyuwei/p/10874773.html

· 图片部分放在<w:p>段落标签里面

  textAlignment w:val="center" 为图片行内居中

  style="width:85pt;height:43pt" 设置图片宽高

<v:imagedata r:id="rId768de9d0ea6111e98c2a28843b052b2f" 设置图片引用地址

注:doc的图片得将它的base64码,和引用定义填充到模板;docx的图片放到word\media文件夹下,并将引用定义填充到模板
<w:p w:rsidR="00A81065" w:rsidRDefault="00BF47F0" w:rsidP="00744A41">
    <w:pPr>
        <w:textAlignment w:val="center"/>
        <w:rPr>
            <w:rFonts w:hint="eastAsia"/>
        </w:rPr>
    </w:pPr>
    <w:r>
        <w:pict>
            <v:shape id="_x0000768de9d0ea6111e98c2a28843b052b2f" type="_x0000_t75" style="width:85pt;height:43pt">
                <v:imagedata r:id="rId768de9d0ea6111e98c2a28843b052b2f" o:title="2"/>
            </v:shape>
        </w:pict>
    </w:r>
</w:p>

 · 表格部分放在和<w:p>同级

w:gridCol w:w="222" 列宽设置
<w:tr> 相当于html table中的 <tr>
<w:tc> 相当于html table中的 <td>
注意:word合并单元格的方式和HTML不太一样,不好描述,多试试自己就能发现规律
<w:tbl>
    <w:tblPr>
        <w:tblW w:w="0" w:type="auto"/>

根据以上规则,结合其他需要的规则,做html结构化题文的翻译,具体翻译代码太多不在这里展示

源码: https://github.com/mao-yuwei/paper_download

注意:spring boot 的项目,启动后访问 localhost:8080 到下载样例页:

可选择试卷,下载格式,纸张大小,字号,答案样式

 

试卷json数据放在:resources\paperdata  

请求方法位置:com\pdl\paperdownload\main.java

 

 

总结:

整个过程就是一个 了解HTML结构,了解word结构,然后翻译,拼接出一个完整word的过程

         

遇到问题: 经常有格式错误或特殊字符导致word打不开的情况,这个是一大痛点,但经过不断优化这样的情况已越来越少了
