PDF表格提取 [英] PDF table extraction
问题描述
我有(相同)数据另存为GIF图像文件和PDF文件，我想将其解析为HTML或XML.数据实际上是我大学食堂的菜单.这意味着每周必须分析一个文件的新版本！ 通常，文件包含一些页眉和页脚文本，以及之间包含其他数据的表. 我已经阅读了一些关于stackoverflow的文章，并且还开始尝试将表数据解析为HTML/XML:
I have (same) data saved as a GIF image file and as a PDF file and I want to parse it to HTML or XML. The data is actually the menu for my university's cafeteria. That means that there is a new version of the file that has to be parsed each week! In General, the files contain some header and footer text, as well as a table full of other data in between. I have read some posts on stackoverflow and I also had started some attempts to parse out the table data as HTML/XML:
- PDFBox || iText(Java)
- Google文档导入
- PDF2HTML || PDF2Table
GIF
- Tesseract-OCR
通过使用PDFBox解析PDF文件，我得到了最好的结果，但是仍然(由于菜单每周更改一次)，它还不够可靠.我收到的HTML有时包含更多(有时更少)的段落"(<p>)，因此我无法足够准确地解析数据.
I have got the best result from parsing the PDF-file with PDFBox, but still (as the menu changes weekly), it is not reliable enough. The HTML that I receive includes sometimes more, sometimes less "paragraphs" (<p>), so that I am not able to parse the data precice enough.
这就是为什么我想知道是否还有另一种方法?
That is why I would like to know if there is an other way to do it?
推荐答案
Tabula 是一个用于从任意PDF提取CSV/TSV表.
Tabula is a pretty good start on a JRuby web interface for extracting CSV/TSV tables from arbitrary PDFs.
