Step 3: If you want to save the edited XML document you can choose the Save function from the menu, the XML data will be displayed in a nice formated text.You can add, edit, or delete any node or brach of the tree stucture Step 2: After the XML data is loaded, it will be displayed in a hierarchical XML Grid which allows you to easily navigate the tree structure.You can choose any of the methods listed in the menu: paste the data directly to the Input Box, open the file from your loacal file system or get it from internet By URL Step 1: Load your XML file to the online XML editor.To resolve the exception error, remove the white-space character that precedes the first node in the Books.xml document. The exception error occurs on the following line of code. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it. When you test the code, you may receive the following exception error message:Īn unhandled exception of type occurred in Additional information: Unexpected XML declaration. String URLString = " XmlTextReader reader = new XmlTextReader (URLString) The AttributeCount property returns the number of attributes for the current node. Use the HasAttributes property to test whether the node has any attributes. ![]() The MovetoNextAttribute method moves sequentially through each attribute in the element. Element node types can include a list of attribute nodes that are associated with them. EndElement: //Display the end of the element. while (reader.Read())Ĭase XmlNodeType.Element: // The node is an element.Ĭase XmlNodeType.Text: //Display the text in each element.Ĭase XmlNodeType. The following code creates an instance of an XmlTextReader object and passes the URL to the constructor: XmlTextReader reader = new XmlTextReader (URLString) The XmlTextReader class has different constructors to specify the location of the XML data. Typically, XmlTextReader is used if you need to access the XML as raw data without the overhead of a Document Object Model (DOM) thus, XmlTextReader provides a faster mechanism for reading the XML. Ĭreate an instance of the XmlTextReader class, and specify the URL.Add the following code sample to the main procedure of the default class: String URLString = " You'll use the constant in the next step with XmlTextReader. Streams are used to provide independence from the device thus, program changes aren't required if the source of a stream changes. Retrieve the XML stream by means of a URL. ![]() ![]() You must use the using directive before any other declarations. Specify the using directive on the System.Xml namespace so that you aren't required to qualify the XmlTextReader class declarations later in your code. You can either continue to the Complete code listing section or continue through these steps to build the application.
