Is it possible to restrict the enumeration of an attribute in dependecy of another attribute of the element?
For example <car manufacturer="x" model="y"> where the model enumeration is dependent of the manufacturer?

I have an XML file that contains lot of records.
For performance reasons, i wanted to read the file using filestream and streamreader. Also, it should read from the last. I need to retrive latest records.
How to move to previous line??
Thanks in advance

Can you count how many lines that you had read by using an integer count?

I am creating an XML string using serialization and it is formed in UTF-16. I want to make it to UTF-8 . What are the possibilities and how can I do it.
Since this is a very urgent issue I don't have time to do R&D. I would appreciate if somebody could give a quick solution.

WideCharToMultiByte() will do that.

Is it possible to use the values from a XML file as the restriction/enumeration in a schema?
The only way I know off is to use XSL to generate a XSD file that only contains the enumeration and then include it into the other XSD file.
For example a customers.xml and a order.xsd as the schmema for orders.xml, where the name should be restricted to those in customers.xml.

Not the only way (e.g. you could put the enumeration into orders.xsd and use DOM to change it according to the content of customers.xml), but I think your approach is better and far more practible, so in my opinion you should go for it.

Ok, this should be simple, but it doesn't seem to be.
XmlDocument object in memory that contains something like:
<content>testing ' and " and ' and "</content>
After I build my document with appropriate nodes, and set the value of the content node (with entities), I need to extract the xml as a string.
So far, every method I've used to extract the xml as a string converts the enties, so ' becomes ' and " becomes ".
The vendor that I'm working with is expecting the entities, not the converted characters.
??

You will need some how to replace the & character with & amp; This way the XmlDocument object will confuse and will translate the & amp; as & only. You will then have & amp;apos; in the memory, which should become & apos; when you get it.
Hope it helps.

Hi
Struggling here to sort, using xpath, an xml file by absolute numerics. My data (unfortunately) comes in comma formatted :-
<line id="1" impact="100,000,000.00"><br />
<line id="2" impact="-110,000,000.56">
I need to display this in order of the absolute value. I have googled and found the following xpath expression, but it doesn't seem to work. Any ideas?
expr.AddSort("concat( substring('-', 2 - (@impact < 0)), '1' ) * @impact", ( System.Xml.XPath.XmlSortOrder.Ascending , System.Xml.XPath.XmlCaseOrder.None, "", System.Xml.XPath.XmlDataType.Number);
Cheers

Sorted! (pardon the pun)
<br />
class myComparer : IComparer<br />
{<br />
<br />
public int Compare(object x, object y)<br />
{<br />
double l1 = double.Parse(x as string);
double l2 = double.Parse(y as string);<br />
l1 = Math.Abs(l1);<br />
l2 = Math.Abs(l2);<br />
<br />
if (l1 < l2) return -1;<br />
<br />
if (l1 > l2) return 1;<br />
<br />
return 0;<br />
}<br />
}<br />
and then use the comparer in the xpath expression
<br />
expr.AddSort("@Value" , new myComparer())<br />
Happy to be told there is a better way...
Cheers

hihi i'm a newbe in Java. If u don't mind, please show me basic code to create an XML file (i understood XML structure), how to retrieve data from this file and write data to it. I need to develop my application in "Eclipse.exe".
Follow your instruction i read on "http://developerlife.com/xmljavatutorial1/default.htm" and see this coding:
import com.sun.xml.tree.*;<br />
import org.w3c.dom.*;
You must have the a String URL of the XML document before you can instantiate a DOM object from it. Assume that an XML file called AddressBook.xml is at the following URL:
http://beanfactory.com/xml/AddressBook.xml. Here is the code to create a DOM object from this URL:
try <br />
{ <br />
String url = "http://beanfactory.com/xml/AddressBook.xml"; <br />
Document doc = XmlDocumentBuilder.createXmlDocument(url);<br />
}<br />
catch(Exception e){}
But i can not download Sun's parser or IBM's parser.
Can u tell me another way : )

These parsers might be available to you:
http://xerces.apache.org/[^]
or
http://www.jclark.com/xml/[^]
Also, I am really a C++ programmer with a little Java programming knowledge. So, I cannot really give a good example using Eclipse.

Simply spoken a XML Schema describes a set of elements and attributes and how these are allowed to be nested. Each XML file that claims to conform to the Schema has to follow these rules.
In your case the Schema has nothing to do with the storing process itself, but it gives you the possibility to validate whether your storage file (still) has the expected structure/content.
Out there are many tutorials on XML and XML Schema that can be easily found with google or the search engine of your choice. I suggest you read some of them, try to solve the problem on your own and come back if you get stuck at some point.

Well your best bet would be to use an instance of XmlDocument class that gives you a DOM representation of your XML file and add nodes to it according to the structure of your XML. Take a look at the MSDN documentation for the XmlDocument class which provides some examples and many links for further reading.

how to read the content of the XML File when we dont know the nodes.

If you're using DOM to access the XML file you can simply iterate over the child nodes of a given node starting with the document's root node.
