Java 从HWPFDocument(.doc文件)中提取段落/字符串后,将数据写入excel文件
在这里,我的代码帮助我将.doc文件中的数据提取到段落和特定的字符串搜索中。我可以使用eclipse运行配置将其手动输出。但是1)我想让它直接输出到excel文件中。doc文件。2)输出必须只指定单元格Java 从HWPFDocument(.doc文件)中提取段落/字符串后,将数据写入excel文件,java,file-io,apache-poi,hssf,hwpf,Java,File Io,Apache Poi,Hssf,Hwpf,在这里,我的代码帮助我将.doc文件中的数据提取到段落和特定的字符串搜索中。我可以使用eclipse运行配置将其手动输出。但是1)我想让它直接输出到excel文件中。doc文件。2)输出必须只指定单元格 public static void readParagraphs(HWPFDocument docx) throws Exception{ we = new WordExtractor(docx); String[] paragraphs = we.getParagraphTe
public static void readParagraphs(HWPFDocument docx) throws Exception{
we = new WordExtractor(docx);
String[] paragraphs = we.getParagraphText();
// To fetch for mode
for(String p: paragraphs){
if(p.startsWith("MODE"))
System.out.println(" "+p);
}
for(String type: paragraphs ){
if(type.startsWith("TYPE"))
System.out.format(" "+type);
}
}
预期产出:
S.no | Doc name | Title | mode | type
=====================================================================
1 | laptop | A12345 | abcd 123456 | efghij A12345/123456
2 | laptop | A12346 | abcd 123457 | efghij A12345/123457
3 | laptop | A12347 | abcd 123458 | efghij A12345/123458
在这里,您可以看到我的HSSF工作手册代码
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("firstsheet");
Row row1 = sheet.createRow((short) 0);
row1.createCell(0).setCellValue("S.NO");
row1.createCell(1).setCellValue("DOC NAME");
row1.createCell(2).setCellValue("TITLE");
row1.createCell(3).setCellValue("MODE");
row1.createCell(4).setCellValue("TYPE");
Row row2 = sheet.createRow(rowNum++);
row2.createCell(3).setCellValue(" "+mode);
row2.createCell(4).setCellValue(" "+type);
Row row3 = sheet.createRow(rowNum++);
row3.createCell(3).setCellValue(" "+mode);
row3.createCell(4).setCellValue(" "+type);
下表见第1页标题文件。只需提取“A12345”
=====================================
| xx | A12345 |xx |
=====================================
下表提供了第2页或第3-6页。取决于每个文档
--------------------------------------------.--------------------
|MODE : Abcde 123456 efghit 234567 sddsldjf 232132 |
|----------------------------------------------------------------|
|INFO |TYPE : efghij A12345/123456 dsflsdjflsd B22323/&123456 |
| |xxxxxxxxxxxxxxxxxalphanumericxxxxxxxxxxxxxxxxxxxxxxxxxx |
-----------------------------------------------------------------
if(p.startsWith(“MODE”)//此方法有助于打印“MODE:Abcde 123456 efghit 234567 sddsldjf 232132”
if(type.startsWith(“type”)//此方法有助于打印“type:efghij A12345/123456 dsflsdjflsd B22323/&123456”
但有些文档没有“类型”,因此,我会选择两个选项,要么从“模式”中查找下一行直到“对齐”,要么从“模式识别”中提取“类型”行。寻求建议
下表在上表之后可用

对于(int i=0;i 对于(int i=1;i您必须更清楚地说明您试图实现的目标。1。)我希望它将输出直接导入excel文件中。doc文件
这是什么意思?2。)输出必须仅指定单元格
我们如何知道哪个输出和哪个单元格?1)当我们运行代码时,它必须使用FileOutputStreams而不是控制台输出创建excel文件。2)请忽略此项。我不太清楚。是的。我希望它在excel中。我知道Apache POI.sry不支持csv,该注释是错误的选项。如果要创建excel文件,请使用类似以下内容尝试(OutputStream out=Files.newOutputStream(new Path(),StandardOpenOption.create_new)){this.workBook.write(out);this.workBook.close();return Path.toFile();}
使用if(type.startsWith(“type”))由控制台输出上的HWPFDocument生成的此字符串方法的结果。如何将此字符串方法中的引用变量/创建对象调用到outputstreams中。我确实查看了链接,对于XSSF和HSSF很好。
