Traditionally its better to encrypt something that has little redundancy, i.e. with little repetition. This is often why text files are compressed before they are encrypted, then decrypted and decompressed at the other end.
It's difficult to suggest something without a little more info about what it is you're trying to encrypt. Do you mean encrypt individual members of a type, like a string field containing a name or something?
For ease its probably better to just encrypt the XML document, if you want to you could always find some .NET code to compress the document beforehand and then encrypt that.

i introduced a namespace into the XML document and all the Xpath construct did not work. It was working before i introduced the namespace. what is wrong?
<?xml version="1.0" ?>
<ROOT>
<TEST>something 1</TEST>
<TEST>something 2</TEST>
<ROOT>
selectNodes(_bstr_t(_T("//TEST")); // working
with namespace
<?xml version="1.0" ?>
<ROOT xmlns="http://www.mynamespace.com">
<TEST>something 1</TEST>
<TEST>something 2</TEST>
<ROOT>
selectNodes(_bstr_t(_T("//TEST")); // error
i added the namespace cos i am doing xml schema validation using MSXML4 which turned out to be ok.
but with the xmlns..., all the xpath expressions failed.
This is my first encountered with namespace in xml document
appreciate any help advise. thanks

what is the equivalent for NamespaceManager for VC++?

IMXNamespaceManager, i think... that said, i've no idea how to use it.
However, take a look at this:

I'd like to generate an XSL using ASP3.0
I've already written the code to make the XSL, but when loading it in to another ASP-page so that it can style a XML, I get the following error:
msxml3.dll error '80004005'
The stylesheet does not contain a document element. The stylesheet may be empty, or it may not be a well-formed XML document.
This while the beginning of the XSL-page clearly makes a root-element:
<%
Response.ContentType = "text/xml"
Response.Expires = 0
Set result = Server.CreateObject("Microsoft.XMLDOM")
%>
<?xml version="1.0" encoding="ISO-8859-1"?>
<%
'// add a node to the result tree for the stylesheet declaration
Set oNewNode = result.createNode("element","xsl:stylesheet", "http://www.w3.org/1999/XSL/Transform")
oNewNode.setAttribute "version","1.0"
oNewNode.setAttribute "xmlns:xsl","http://www.w3.org/1999/XSL/Transform"
result.appendChild(oNewNode)
'// the stylesheet declaration is the outermost grouping tag. It is the root
'// element and parent to all other elements
Set root = result.documentElement
...
What might be a sollution to fix this?

Why do you want to do this ? Why not generate it with XSL ?

I have a xml file which has to be sent to another system with the node name changed.
eg:
"<emp name="me" id = "30">"
has to changed to
"<employee name="me" id = "30">"
This is a bulk operation where performance is critical. The platform is vb6.0/vb.NET. Can any one help me out

Honestly I would not even use XSL for this. The change is so simple that just a string-replace function would be best. With XSL you would have far more overhead.
Even RegEx would probably be a better choice.

1. If the XML Document is large then, using DOM for transformation may not be practical. If that is the case, then under the .NET scenario, you should use the XmlTextReader and XmlTextWriter objects.
2. If the XML Document is not large enough then, you can use the DOM Methods which can be pretty verbose even in .NET.
3. Using an XSLT approach may be convenient if the document generally does not exceed 50 Kb.
the XSLT file is as follows:
<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@* | node()">
<xsl:copy><xsl:apply-templates select="@* | node()" /></xsl:copy>
</xsl:template>
<xsl:template match="emp">
<employee>
<xsl:copy-of select="@* | node()"/>
</employee>
</xsl:template>
</xsl:stylesheet>

I write:
<xsd:simpleType name="money">
<xsd:restriction base="xsd:decimal">
<xsd:fractionDigits value="2" />
</xsd:restriction>
</xsd:simpleType> to define a simple type in a schema file.
Then i use <cost>239.00</cost> in an XML file, where cost is of type money.
When i try to validate the XML with MSXML 4.0 it generates this error:
The element cost has an invalid value according to its data type.
If i remove the 9 from 239.00 everything will be ok.
What's wrong here? MSXML 4.0?
The case comes from an XML-Schema tutorial

The answer is

You're right

Try this :
...
<xsd:restriction base='decimal'>
<xsd:totalDigits value='10'/>
<xsd:fractionDigits value='2'/>
<xsd:minInclusive value='0.00'/>
<xsd:maxInclusive value='1000.00'/>
</xsd:restriction
...
And let me know

I've tried. Same story.
But it's not unusual. I had a problem with the pattern facet also. Guess MSXML has to grow up a bit.
If you need the sources i can send them to you.

I save comments from people in a XML file, but when I view it in IE it just show me the half or so ofthe data between a block.
I know that '&' is not alowed in XML but is there any others?

Its not that it isnt allowed, its just that to use it you must escape it. The restricted characters and their escaped versions are:
& == &amp;
' == '
> == &gt;
< == &lt;
" == &quot;
So:
"The fat cat & his dog"
Becomes:
&amp;The fat cat &amp; his dog&amp;

I'm learning XML now. Creating a simple xml file which is as follows:
<customer id="xyz">
<name>
<first>John
<middle>Smithy
<last>Doe
<line1>123 Some Street <line2>P.O. Box 555 <city>Anytown
<state>NC
<zip>55555
<phone>
<home>5551212
<work>5551213
<online>
<email>john@doe.com
<url>http://www.doe.com
but when trying to run it in IE6, is returned the following error:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
--------------------------------------------------------------------------------
The system cannot locate the resource specified. Error processing resource 'customer.dtd'. Error processing resource 'file:///D:/XMLExcise/xml1.xml'. Line 2, Position 42
So, what does this mean and what's the solution for it? Thanks!

Are there any documents or arctles that you have read explains XML for a starter?
not elaborately,but basic conceptions,with examples preferably,short but to point for future learning.

There are billions, which is part of the problem.
