Question about sax and xml entity!

[Renato Tegon Forti <re...@acm.org>]

Hi All,

I have one doubt (or better, a problem!)

I heve one xml, like this:

// .

<xNome>A&amp;S ELETRO</xNome>

//..

Then I run a sax parser. I have

class sax_handlers 

   : public HandlerBase

   , private XMLFormatTarget

{

void characters(const XMLCh* const chars,   const XMLSize_t length)

{              

   char* name_char = XMLString::transcode( chars );   

   std::string name = name_char;  

   XMLString::release(&name_char);

// .

}

My problem is that in 'name' I have only 'A'! The '&amp;' not appears on my
variable!

My question is, where is my '&amp;'?

Thanks

Hi Renato,
the character() callback can be invoked several times to build the 
string found inside an element node; this can happen if the string 
started at the end of the current buffer of text loaded from the file, 
or (like in this case) because an entity reference has been found and 
potentially this could require loading an included file. You will see 
the ' character in the next call, followed by a third call to report "S 
ELETRO".
It's the SAX handler's task to join these three calls into a single line 
of text.

Hope this helps,
Alberto
