MXXMLWriter

kg
Anyone know how to stream MXXMLWriter to a file? No matter what I try I end up with an empty file. My last attempt

MSXML2::IMXWrit erPtr pWriter
hr = pWriter.CreateI nstance(__uuido f(MSXML2::MXXML Writer40))
_ASSERT(SUCCEED ED(hr))

ISAXContentHand lerPtr pContentHandler
pContentHandler = pWriter

ofstream m_pFileStream;
m_pFileStream.o pen( outFile, ios::out )

pWriter->put_output( _variant_t(m_pF ileStream) )

hr = pContentHandler->startDocument( )

<write some xml

hr = pContentHandler->endDocument( )

m_pFileStream.c lose()

Hi, I doubt that ofstream supports the IStream interface. That is required
for IMXWriter. Also, check the return value when you set the stream, to find
mistakes like this one in the future.
For an implementation for a file stream of the right kind, look here:

Hi, I am trying to use MXXMLWriter with the indent flag to pretty print an XML document from vb6. Although the output is mostly indented in a reasonable way, the end tags are always bunched up at the end of a line not on a line by themselves e.g. <a> <b>

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
