Java poi3.9解析word文档

大家好，关于Java poi解析 word2003 doc文档资料太少了，希望大家能帮个忙，提供点思路

我想要做一个题库网站，题目源是word文档(那种考试试卷电子版)

1. Java poi图片位置处理
   HWPFDocument = new HWPFDocument(new FileInputStream("2011小学数学毕业模拟试卷1.doc"));
   List picA = docA.getPicturesTable().getAllPictures();//获取所有文档中的图片
   
   int length = doc.characterLength();
   for(int m =0;m<length-1;m++){
       Range range = new Range(m,m+1,doc);
       for(int j=0;j<range.numCharacterRuns();j++){
           CharacterRun cr=range.getCharacterRun(j);
           if(cr.getPicOffset()!=-1){} //表明是图片？然后标注明是list中的第几张图片
       ｝
   ｝

2. 数学试卷的高等数学公式
   解决思路一：poi是能解析成wmf图片(windows 画图板)，但是wmf并不是网页图片显示格式
   解决思路二：word安装mathtype工具后，可以将word文档中由mathtype公式编辑器编辑的数学公式转化成mathml，然后再解析word文本和mathml的混合文档
   但是数学公式在数据库中怎么存储呢？

3. 是否能有其他的工具实现，
   1.网上看到c#解析word文档更好？(微软自己的东西)
   2.VBA来做？
   3.我不知道用itext来解析pdf能否相对简单一点

#1

你确定java 解析word 的资料少？

#2

感觉都讲得很浅，并不是我想要的   poi word部分其官方的API，一些方法也讲得很简单
有过经验的朋友能一起来帮忙给个建议吗？

#3

InputStream input = null;  
HWPFDocument doc = null;
String content = null;
try {
input = new FileInputStream("2011小学数学毕业模拟试卷1.doc");
doc = new HWPFDocument(input);
content = doc.getRange().text();
        List<Picture> picA = doc.getPicturesTable().getAllPictures();// 把word中数学公式以wmf图片的格式读到List中
Picture p = null;
for (int i = 0; i < picA.size(); i++) {
    p = (Picture) picA.get(i);
    if(p!=null){
        FileOutputStream output = new FileOutputStream("F://" + i + "."+p.suggestFileExtension());
        p.writeImageContent(output); 
        output.close();
    }
}
} catch (Exception e) {
e.printStackTrace();
}

int pici = 1;
int length = doc.characterLength();
for (int m = 0; m < length - 1; m++) { 
Range range = new Range(m, m + 1, doc); 
for (int j = 0; j < range.numCharacterRuns(); j++) {
CharacterRun cr = range.getCharacterRun(j);
if (cr.isOle2()) {     // 表明是ole2对象，word文档数学公式由mathtype编辑的ole对象
cr.replaceText(cr.text(), "方程式"+pici);
                        //貌似只会替换一次
pici++;
}
}
}

我也遇到这样的问题

#6

大哥，现在实现了没有？小弟想请教一下

回复楼主 关于java读取word 公式问题

刚好今天我也碰到一个这个样的问题， 我用的是jacob 将word 转成html， word里面的公式会变成图片。
html就用Jsoup 解析的。

缺陷是 用jacob 服务器必须是windows 的。 而且需要装office2007 


今天找了一天的资料。没发现java可以操作word 公式的。。 

#8

用openoffice看看，是跨平台的，word中的公司是作为图片处理的

#9

第一问，也许资料少，但是官方API里肯定有例子，下载后的POI方法中也有demo。照着学，挨个测试一下效果。
第二问，数学公式中的任何符号都有对应的ASSIC编码吧，存储编码数字就可以了

#10

服务器是windows的方法多些如7楼说的jacob\及自己开发的插件，其它的用　openoffice但支持的也不是很好，加的样式什么的有时显示不太准确

#11

关于解析word中公式你解决没，之前看有说是用VBA，可是我们是要求可跨平台的，这下伤不起了

后来因为没有实现，这个不了了之了！不知道现在有什么实现思路了吗？

嗯，有思路了，正在做！，用openoffice解析，对于docx文件，要自己改里面的配置文件
