C code :

void applyXslt(Saxon::Api::XdmNode^ fxmlFile, Saxon::Api::XsltTransformer^ xsltFile, const std::string& outputFile)
{
    // Apply the xslt to the cached xml
    auto processor = gcnew Saxon::Api::Processor(false);

    xsltFile->InitialContextNode = fxmlFile;
    auto serializer = processor->NewSerializer();    \\ Error occurs here

    System::String^ output = gcnew System::String(outputFile.c_str());
    serializer->SetOutputFile(output);

    xsltFile->Run(serializer);

}

It somehow fails to create a serializer , It worked when i created a test project , but now it doesnt seem to work. Is this a bug in Saxon ??

CodePudding user response：

To allow you to mark the question as answered, I summarize what seemed to have helped from the comments.

In general, the Processor class is central, see https://www.saxonica.com/html/documentation10/dotnet/dotnetapi.html saying

The first thing the application needs to do is to create a Processor. The Processor holds configuration information for Saxon, and shared resources such as the name pool and schema pool. It is possible to run multiple processors concurrently if required, but it is usually more economical for all Saxon processes within a single application to use the same Processor.

So based on that your code should hold on to the Processor you used to create the XdmNode and XsltTransformer you already pass in to your function applyXslt and pass that processor instance in as well as a parameter to then use it to create that Serializer.
