There are encryption classes in .NET and also support in the Xml namespace for encrypting/signing XML. There isn't necessarily a "best method", it all depends on what you want and how you want it to work.

Is there a way to serialize non-textual objects, for example fonts and colors, using XML Serialization. working fine with binary formatter, but I have to use XML for political reasons.
Thanks PhilD

XML is text based so the question is can you represent your data in text. The answer of course is Yes. There different ways to do it. Lets look at a Date. It's a numeric type so we can store the string representation of the number or we can transform the date into a human readable format and store that as long as we can parse it back into the numeric type it will work. Another approach is to use a standard binary data mechanism in XML which is Base64 encoding.
Does that help?

Yeah, but I dont have to do the transforms on a double or or an int, nor a decimal (I think) so why should I have to do common things like Colors & Fonts - I guess I resent having to delve into XML serilization when binary works fine.

What are we, girl friends? I don't think so. 
Besides, if you don't like writing code just switch to being a Visual Basic Drag n Drop developer.

given i've been writing the stuff for 30+ years I guess the thrill of writing stuff that don't need writing has gone. BTW only Basic I ever used was Dartmouth Basic on a GE timesharing system - Gates would have been at scool then & I dont mean grad or high scool

i am using xpath to navigate through this xml file.
i used the following code to navigate through items node.
XmlDocument doc = new XmlDocument();
doc.Load(xmlfile);
XPathNavigator nav = doc.CreateNavigator();
XPathExpression exp = nav.Compile("rss/channel/item");
XPathNodeIterator iterator = nav.Select(exp);
XPathNodeIterator iter1;
while (iterator.MoveNext())
{
iter1 = iterator.Current.SelectChildren("media:content", "");
if (iter1.Count > 0)
{
while (iter1.MoveNext())
{
if (iter1.Current.HasAttributes == true)
{
string url = iter1.Current.GetAttribute("url", "");
}
}
}
}
but when i execute the code, the iter1.count always returns zero. if i select anyother children(like title or description)i am able to display the value.but when i select media:content(one of the subitems of item) i am not able to display the attribute value.
Where am i going wrong?
Any suggestions please
Thanks in advance.
Regards
Anuradha

hi guys,
i solved it by myself. for everybody's reference,
iter1 = iterator.Current.SelectChildren("content", "http://tools.search.yahoo.com/mrss/");
i need to include the namespace URI in the selectchildren method and it worked.
Thanks

I am trying to generate a Word document for an ASP.Net application -- all users will have Word 2003.
I created a simple document in Word (Simple.doc).
Then, I used an XML Schema found in Simple.xsd and placed a couple of XML placeholders in the document.
I saved it as Simple.XML.
Downloaded and ran wml2xslt to create simple.xslt.
However, I am a little stuck as to how to get the data from my application into xml using this xslt file. Every example I can find seems to assume all data will be coming from a SQL database or databound web/win forms.
I would like to do something like:
Swap("xmlDataElementName", myObject1.ToString());
Is this doable; any help is greatly appreciated.

I want to figure out the formula in getting the following:
$2500 loan amount
239.9961% APR
12 month term
Bi-weekly payment (26 payment total)
What is the formula for each payment?
What is the formula for the Total Finance Charge?
How can I calculate Bi-weekly equal payments??
We know that each payment will be $251.96 (Equal Payments) But how have they come up with such formula?? And where?
HELP!?!?!?!?!

I will assume that your $251.96 is paying both interest on the balance and part of the loan is repaid each month.
So each each payment = interest + repayment
I used to Excel and "Goal-Seek" to work out the nominal (annual) rate of interest, it is 234.214%. Therefore each bi-weekly payment (assuming 52 weeks in a year) is 1/26 x 234.214% which is 9.008%
This is the interest part: so in first week interest is balance x 9.008% which is $225.206
Subtract this from $251.96 and you have the net repayment that month, $26.76.
For bi-week 2, interest on the balance is now $2473.24 x 9.008% .. etc
As to formulas I don't know if there is one, it's so long since I did all this stuff.. As you can see the interest is calculated monthly based on the remaining balance, and totals $4050.96

I am venturing into the .NET XML world and have already run into a problem.
I have some very simple (I think) XML that defines several loan rate values, with attributes indicating the min and max amount for the loan:
<code>
<LoanInformation>
<LoanRates>
<Loan MinValue="001000.00" MaxValue="004999.99">
<Margin>10.25</Margin>
<Floor>14.75</Floor>
</Loan>
<Loan MinValue="005000.00" MaxValue="009999.99">
<Margin>5.25</Margin>
<Floor>9.75</Floor>
</Loan>
</LoanRates>
</LoanInformation>
</code>
So, a loan for $2500.00 should have a margin of 10.25/floor of 14.75, while a loan of $7500.00 should have a margin of 5.25/floor of 9.75.
I want to access these values in my C# code to calculate the rate/payment, but am stuck.
<code>
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath(@"~\App_Data\LoanInformation.xml"));
string xPath = string.Format("//LoanRates/Loan[@MinValue >= '{0:000000.00}' and @MaxValue <= '{0:000000.00}']", plcdata.LoanAmount);
XmlNode node = xmlDoc.SelectSingleNode(xPath);
</code>
node seems to always be null, unless I remove the 'and @Max ..' clause. I added the leading zero's in case text vs. number comparison was causing a problem.
Any pointers would be greatly appreciated.

Your XPath query is incorrect. Your code should read:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath(@"~\App_Data\LoanInformation.xml"));
string xPath = string.Format("//LoanRates/Loan[@MinValue <= '{0:000000.00}' and @MaxValue >= '{0:000000.00}']", plcdata.LoanAmount);
XmlNode node = xmlDoc.SelectSingleNode(xPath);

Duh! I've been trying various combinations, *assuming* the problem was XML (and my lack thereof) related. Stupid logic!

Hi, I wrote a Schema Validator in C#.NET.
XmlTextReader R = new XmlTextReader(FileToParse);
XmlValidatingReader V = new XmlValidatingReader(R);
try
{
XmlSchemaCollection xsc = new XmlSchemaCollection();
xsc.Add("", SchemaFile);
V.Schemas.Add(xsc);
V.EntityHandling = EntityHandling.ExpandEntities;
V.ValidationEventHandler += new ValidationEventHandler(ShowValidationErrors);
while (V.Read())
{
}
//V.Close();
//MessageBox.Show("Validation Completed");
//R.Close();
}
catch (XmlException xe)
{
//Display exceptions
}
catch (XmlSchemaException xse)
{
//Display exceptions
}
catch (Exception ee)
{
//Display exceptions
}
finally
{
V.Close();
MessageBox.Show("Validation Completed");
}
This works fine if the xml file DOES NOT contain entity declarations.
But, If the xml file contains any entity declaration (as below), the 'ValidationEventHandler' throws errors like
"Validation Error: The 'mytest' element is not declared.Line : 8 Position : 2"
"Validation Error: The 'articles' element is not declared.Line : 9 Position : 2", etc.....
How do I overcome this in C#.NET

hi ,
can someone tell me what is xml serializer and why it works only on public fields
Thanks
Mukkanti
|
|
|
|
|

Because private means that the proprty/field/method/whatever is only visible to code inside the scope that declares it. Since an XmlSerialer class is not declared as part of your class code, it can't see inside your class.

All I want to do is select all the nodes under the docment root. e.g:
<?xml version="1.0" encoding="UTF-8"?>
<Categories>
<Category>
<content_provider_id type="integer">1</content_provider_id>
<id type="integer">2</id>
<name>Traffic Alerts</name>
</Category>
<Category>
<content_provider_id type="integer">1</content_provider_id>
<id type="integer">1</id>
<name>News Alerts</name>
</Category>
<Category>
<content_provider_id type="integer">1</content_provider_id>
<id type="integer">3</id>
<name>testing category</name>
</Category>
</Categories>
What xpath would return all the Category nodes? But I don't want it to be specific to this xml file.
