Java PDFBox，从表的一列中提取数据 [英] Java PDFBox, extract data from a column of a table

问题描述

我想了解如何从这个 pdf(例如图像)中提取 http://postimg.org/image/ypebht5dx/

I would like to find out how to extract from this pdf(ex. image) http://postimg.org/image/ypebht5dx/

例如，我只想提取列TENSIONE[V]"中的值，如果遇到空白单元格，我会在输出中输入字母X".我该怎么办?

For example, I want to extract only the values ​​in the column "TENSIONE[V]" and if it encounters a blank cell I enter the letter "X" in the output. How could I do?

我使用的代码是这样的:

The code I used is this:

 PDDocument p=PDDocument.load(new File("a.pdf"));
 PDFTextStripper t=new PDFTextStripper();
 System.out.println(t.getText(p));

我得到这个输出:

推荐答案

这些只是指导方针.在您使用时使用它们.这也没有经过测试，但可以帮助您解决问题.如果您有任何问题，请告诉我.

These are just guidelines. Use them upon your use. This is not tested either, but help you solve your issue. If you have any question let me know.

String text = t.getText(p);
String lines[] = text.split("\\r?\\n"); // give you all the lines separated by new line

String cols[] = lines[0].split("\\s+") // gives array separated by whitespaces
// cols[0] contains pins
// clos[1] contains TENSIONE[V]
// cols[2] contains TOLLRENZA if not present then its empty
