converting XMLCh* in unicode to string

[jinesh kj <ji...@gmail.com>]

hi,

I have some doubts in this regard. I am having a program which reads the
text content of an XML element by getTextContent and i want to transcode it
to unicode. I have a simple doubt out of topic, like can i store the string
in std::string as other non unicode strings and use functions like find and
all?(basically i need to read the string word by word). Also
XMLString::transcode will transcode to native encoding i believe. If I use a
std::wstring, can i solve the problem?

regards

Jinesh K J

P.S: sorry, i know the question is more related to c++, if anyone know the
answers please  help me.

String data in Xerces-C is encoded in UTF-16, so it's already Unicode data.

Yes, XMLString::transcode() will transcode a string to the local code page, 
so it's not very helpful if you care about the fidelity of the data.  You 
can transcode UTF-16 to UTF-8 and store the UTF-8 bytes in std::string, but 
you may not be able to use all of std::string's member functions.  There 
was a very recent thread on the mailing list about this, so you should 
review the recent postings to the list.

Unlikely, unless your platform support UTF-16 for the wchar_t data type. 
Windows is the only platform that does this consistently.  Otherwise, you 
will probably have to fall back to std::vector<XMLCh>.
