Hi to all :)

 

I send this exampe to harbour-users, but nobody answered me. I think it's a bug in TXmlDocument class.

 

I have simple XML with attributes which contaings special characters  
  and 
 -- sample XML is in attach. This is important line:

 

<Stavke naziv="DETA-&#xD;&#xA;-1603"/>

 

For reading I use this simple code:

 

PROC Main

   CLS

   oDoc := TXmlDocument():new()

   oDoc:read(MemoRead("c:\tmp\pp.xml"))

   x1 := oDoc:findFirst ("Stavke")

   ? s1 := x1:aAttributes["naziv"]

   x2 := oDoc:findNext ()

   ? s2 := x2:aAttributes["naziv"]

   x3 := oDoc:findNext ()

   ? s3 := x3:aAttributes["naziv"]

RETURN

 

Result (characters for special symbols) change every time I start this program???

 

 

Thanks in advance,

 

Nenad Batocanin

TXmlDocument  use to parse xml   function from   ....\core\contrib\xhb\hbxml.c

Some fragment:
...
               else if( strncmp( bp, "apos", iAmpLen ) == 0 )
                  chr = '\'';
               else if( *bp == '#' )
               {
                  if( *( ++bp ) == 'x' ) /* Hexadecimal */
                     chr = ( ( *( bp + 1 ) - '0' ) << 4 ) + ( *( bp + 2 ) - '0' );
                  else                   /* Decimal */
                     chr = atoi( bp );
               }
....

So,  enity   type :   &#xHHHH;  
 -  must be equal 2 chars len
 -  buggly when use alpha A-F or a-f

 - enity  &#NNNN;    must be < 255  (no Unicode )

Many thanks to you and everyone who helped me clarify the problem!

 

For now, I solved the problem by doing StrTran before parsing the XML.
