need help with binary data format

[al...@cardsystems.com]

Hi,
I wonder if someone could answer a simple question. I am new to XML, so
maybe the question I have is pretty trivial, but here it is:
I am using xerces C++ parser on NT platform and it works fine unless I have
binary characters in my XML data. Assuming that I know the structure of the
XML, field name that might contain binary characters, and even all the
possible binary characters that can appear (there are only 2 or 3), what
would be the easiest way to parse correctly?
 
Any help is greatly appreciated.
Thanks,
 
Alex K.

You can't just include binary data in XML. XML consists of printable characters.

One solution is to uuencode the binary data before placing it in XML. Another solution would be to encode your 2 or 3 characters to something like &mychar1;.

We have many possibilities for binary characters and chose to enter them in
hex or octal.
<sometag data=”0x33” />
<sometag data=”044” />

In the C++ code we wrote a class to process the hex or octal.
