Open and read documents in C++

If you want to open a text file and work with the data in plain-text format, you can do it using the most basic features of the C++ language and operating system. As for reading office documents, presented in a wide variety of file formats (DOCX, DOC, PDF, RTF, ODT, HTML, etc.), this task is more difficult to solve, since such documents are described by complex tree-like data structures within the DOM model.

Our C++ library is a cloud-based solution that will allow you to open documents in any office and web format. This distributed approach gives you flexibility in software development using C++ language, as all resource-intensive document processing will take place on Aspose servers. All you need is to get private keys to access Cloud API in C++ code.

Programmatically read Word, PDF documents in C++

You can iterate over document elements, or you can search for specific elements in the DOM tree. We provide a wide range of C++ functions both for working with the structure of the document and with the data contained in the document nodes.

The following C++ code example will help you quickly figure out how to load a document and perform some actions on it.

Upload a document you want to access
Run code
using namespace aspose::words::cloud;

auto config = std::make_shared<ApiConfiguration>(L"####-####-####-####-####", 
   L"##################");
auto wordsApi = std::make_shared<WordsApi>(config);
std::wstring fileName = L"Input.docx";

auto requestFileContent = std::shared_ptr<std::istream>(
   new std::ifstream(
      std::filesystem::path(getFileTextUtf16(fileName)), std::istream::binary));
std::shared_ptr<requests::UploadFileRequest> uploadDocumentRequest(
    new requests::UploadFileRequest(
        requestFileContent, std::make_shared<std::wstring>(fileName)
    )
);
wordsApi->uploadFile(uploadDocumentRequest);

auto requestParagraph = std::make_shared<aspose::words::cloud::models::ParagraphInsert>();
requestParagraph->setText(std::make_shared<std::wstring>(
   L"Reading and writing to the file in the cloud occurs automatically."));
std::shared_ptr<requests::InsertParagraphRequest> insertParagraphRequest(
    new requests::InsertParagraphRequest(
        std::make_shared<std::wstring>(fileName), requestParagraph
    )
);
wordsApi->insertParagraph(insertParagraphRequest);

std::shared_ptr<requests::DownloadFileRequest> downloadDocumentRequest(
    new requests::DownloadFileRequest(
        std::make_shared<std::wstring>(fileName)
    )
);
wordsApi->downloadFile(downloadDocumentRequest);
