Creating xml file with asp.net




















UTF8 ;. WriteStartDocument true ; writer. Indented; writer. WriteStartElement "Books" ;. WriteEndElement ;. WriteEndDocument ;. WriteString bName ; writer. WriteString bPrice ; writer.

You save time, because you don't have to worry about knowing how the XML namespace and classes work and the little subtle nuances that go with it, but it's also time consuming, because formatting and error checking is left up to you. Good method when you need an XML file in a pinch, but it's error prone and doesn't tell you much about the content in the file.

Here is a quick example that makes use of the StringBuilder class to concatenate each different element of our XML document. Our objString object now holds a full XML document, albeit still in string format. Up next we'll use the StreamWriter and write the stream, obviously. After that we close our reader and we're done. We have a shiny new XML file. You don't need to use a StringBuilder for this, but more than likely you'll be working with a much larger dataset than what I have in the example, and a StringBuilder is the better approach for that compared to regular string concatenation.

In order to use the StringBuilder you will need to specify the System. Text namespace. Also to use the StreamWriter class you will need to specify the System. IO namespace. This approach does have a slight learning curve, as there are a good number of classes to work with and functions to call that are very specific.

It offers more exact control of the XML document however. You create an XmlDocument when you need to process an XML tree or will be inserting elements in a non-sequential manner. But you choose your poison. It will do the job if need be. Below is the code to create a new Xml Document and then simply add an XML declaration and a namespace. As you can see it's quite a bit of code compared to our example above, but on the upside every XML element is it's own object, with functions and properties.

It does offer validation, and you can manipulate the XML in any way that you would want. We'll start by declaring a new object of type XmlDocument , which lives in the System. Xml namespace. Yet a third approach, depending on your needs. The XmlWriter class is a forward only non cached way to write xml content to a stream. The benefit in this? It's fast. I've read a few links but a little confused.

Or how would the file be created? How could i nest some fields? You don't need a schema to create a XML file. Schema file validates the XML. You will declare a schema file that will take care of it. So, as a beginner you might NOT want to mix things up. Step 3: After that add the following namespaces in the code behind:. Step 4: Now write the following code in the code behind file:. BindDatalist ;.

MapPath "Employee. ReadXml xmlreader ;. Close ;. DataBind ;. Step 5: Write the following code in the click event of the submit button, so that the data that is entered is stored in the XML File:. Load Server. Now the data stored in the XML file can be shown. CreateElement "Details" ;. CreateElement "Name" ;.
