Hello all,
I hope this is the correct place to ask this. I didn't want to ask on the
developers list as it doesn't seem like the proper place to ask questions about
end usage patterns.
In short, I am having an issue using the MemBufInputSource to take a chunk of
XML contained in a std::wstring and pass it to DOMBuilder::parse. I am creating
the input source as such:
MemBufInputSource xmlSource(
reinterpret_cast<const XMLByte *>(xml.to_utf8()),
static_cast<const unsigned int>(xml.length() * sizeof(wchar_t)),
"pidc_rules_file",
true
);
Ignore the 'to_utf8' call, that is just some encoding agnostic extensions we
have added to our std::wstring/std::string sub-class so we can actually compile
the code ANSI when required. I am telling the input source to adopt the buffer
that I pass to it, so that it isn't referencing back to the std::wstring's
internal buffer. Note in this case the code is compiled _UNICODE, so the
to_utf8 call is a simple pass-through to std::wstring::c_str, there is no
XMLString::transcode going on here.
When I attempt to call DOMBuilder::parse like so:
m_Doc = m_Builder->parse(Wrapper4InputSource(&xmlSource, false));
I get the following error passed to my error handler:
An exception occurred! Type:UTFDataFormatException, Message:invalid byte 2 (╠)
of a 2-byte sequence.
Obviously it's not liking part of the UTF-8 sequence I am passing it, but why?
The XML itself is fine. I can tell my builder to load the document from a file
using parseURI, and all works well. For functionality reasons, I need to be
able to load an arbitrary chunk of XML outside the scope of loading a file. Is
there another, more intuitive way to do this aside from creating a
MemBufInputSource? Please note, I am doing XML Schema validation, so I would
like to stick to DOMBuilder if possible.
I am pretty new to Xerces (although not XML or XML parsing in general), so I
fear I am simply missing something obvious here.
Any thoughts?
