Re: How to specify a Processing Instruction?

[ComCity <mikeb@comcity.com>]

This is for UPS (United Parcel System) XML Cost calculator.  I'm having to
transfer a node from one xml document to another.  When I do this without
specifying the encoding which is what I was doing originally, the UPS parser
was complaining that the "text" in the node had changed during my transfer.
When I look at the text, I note that the text is originally one long set of
characters with black squares where carriage returns should be.  I believe
this means that the node is originally "encoded".  When I transfer it by
virtually any and every means I try with MSXML including setting a node,
replacing a child node,etc., the text is formated by MSXML and the carriage
returns are changed to real carriage returns, etc.  According to UPS and
what I need to do, this "will not" work.

This access text must be preserved exactly as is and, in addition, the
encoding of ISO-8859-1 must be at the top of the XML document.  If I create
a "fake" xml document using notepad preserving the "encoding" (or what I
believe to be encoding) of the text and putting the encoding specification
at the top, the XML document is accepted by UPS when they manually submit
it.

So, I know what I need to do, but it totally escapes me on how I need to do
it.  Why?  Because, I have no way to keep MSXML from changing this text as
it is saved into the second XML document.....I was hoping that if I simply
create the document as ISO-8859-1 from the beginning, the MSXML parser will
leave this text "as is".  But, I don't even know if this will work.....its a
pure hypothetical guess at this point.  The only other solution I could come
up was to somehow tell MSXML "not" to change the encoding of this node, but
there's no way to do that that I know of.

I could send my XML document....what I currently am able to do and what UPS
says it needs to look like as an attachment if that would help.

Thank You very much.
