Name ; The above line of code will return the name of the first childe node. The first method that you should call while reading the elements is MoveToContent method. In order to instantiate an XmlReader object, you simply have to call static Create method of the Static XmlReader class and pass this method the path to the XML file which you want to read.
WriteLine xmr["status"] ; The above lines will display the value of the id and status attributes of the start element student.
WriteStartElement "item" ; writer. However, you should always keep in mind that the element that you are going to read is the next element in the XML document. Similarly, if you want to read a string which actually represents some XML data, you can use following technique as we did in Example1: Xml namespace to which XmlReader class belongs.
We can also use MoveToAttribute method and pass it the name of the attribute of the element to which currently the cursor is pointing. The output of the code in Example2 is as follows: AttributeCount ; The above line would display the number of attribute of the student element.
XmlDocument object is best explained with the help of an example. Have a look at the 6th example for this article. Like XmlReader, XmlWriter object is also instantiated through Create method where first parameter is the path to the XML file to which you want to write and the second parameter is the settings.
This method actually moves the XmlReader to the content, skipping the introductory information. In the following code, the WriteAttributeString method changes the namespace URI for the "x" prefix from "" to "abc". Have a look at the 4th example of this tutorial: The following line of code does this in our example: Output3 Here in the output, 2 is the number of attributes of the start element student.
But before moving towards our next example, modify your Student.
This can be useful when you know how to best optimize the number of namespace declarations. Declare namespaces manually by using the WriteAttributeString method.
Next, you call ReadStartElement and pass it the name of the start element of your document. The attributes that are written depend on the type of node the reader is currently positioned on: Have a look at the 3rd example of this article. If you want to get the name of the parent of the first child, you can simply call ParentNode and its Name property.
The output of the code in Example4 is as follows: Xml namespace that contains XmlReader class. Now the cursor is pointing to the start element or start node.
Now if you compile and run the code in Example6, you would find that the XML file that would be created looks like this: Output5 The output only shows that XML document has been written.
The file should look like this: If the data store has schema information available to it, the WriteValue method throws an exception if you try to convert to a type that is not allowed.important: XMLWriter expects UTF-8 data from you.
It can output xml in various encodings, but input should be strictly utf-8! ext/libxml/libxml.c Superclass: Object The XML::Writer class provides a simpler, alternative way to build a valid XML document from scratch (forward-only) compared to a DOM approach (based on XML::Document class). For example, you can call WriteValue to write a typed value, WriteCharEntity to write a character entity, WriteAttributeString to write an attribute, or you can write a child element.
This is a more sophisticated version of the WriteElementString method.
XmlWriter to write Element String with Attribute. Ask Question. up vote 14 down vote favorite. 2. I am using XmlWriter and I am wondering if some one ever tried to write the xml element string (leaf node) with attributes so that the output would look like I could be wrong in manipulating but essentially what I want to achieve is just to.
Function: xmlTextWriterEndDocument int xmlTextWriterEndDocument (xmlTextWriterPtr writer)End an xml document. All open elements are closed, and the content is. In this section we are going to explain that how you can use XmlWriter class to write an XML document.
XmlWriter class belongs to the same mint-body.com namespace to which XmlReader class belongs. Also both the classes share man common characteristics.
Like XmlReader, XmlWriter object is also instantiated through Create method where first .Download
