Parsing pdf files
提问by desi
I have a requirement to split a large pdf document into smaller files based on the content of the file. We use BCL easyPDF to manipulate pdf files. easyPDF can split pdf documents based on a page number, but it cannot split the document based on the file content. Also it does not have a search function (as far as I can tell, if I am wrong please someone let me know.) to determine the location of the content.
我需要根据文件的内容将大型 pdf 文档拆分为较小的文件。我们使用 BCL easyPDF 来操作 pdf 文件。easyPDF可以根据页码拆分pdf文档，但不能根据文件内容拆分文档。它也没有搜索功能（据我所知，如果我错了，请有人告诉我。）来确定内容的位置。
Now can someone tell me how I can find the location of text in a pdf file using .net?
现在有人可以告诉我如何使用 .net 在 pdf 文件中找到文本的位置吗？
Thanks

You might try Docotic.Pdf libraryfor your task.
您可以尝试使用Docotic.Pdf 库来完成您的任务。
The library can retrieve a collection of words with their bounding rectangles from PDFs. This should help you to find location of the text in a file.
该库可以从 PDF检索带有边界矩形的单词集合。这应该可以帮助您找到文件中文本的位置。
The library could also be used to extract text (with or without formatting).
该库还可用于提取文本（带或不带格式）。
