Java poi3.9解析word文档

[SHENZHOUCHEN91]

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

用openoffice看看，是跨平台的，word中的公司是作为图片处理的

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

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？

[记忆向前看]

显然是把公式截成图片了啊

显然你不懂mathml.ooxml！

[记忆向前看]

的确mathjax很不错
