I have seen that at times, we need to generate XML using code. This is in contrast to web services, wherein XML is generated by the compiler. In this post, I would like to give some pointers about creating XML files using C# - the "
XmlWriter" class. Consider the following piece of code:
XmlWriter xml = XmlWriter.Create(@"c:\file.xml");
This would instantiate an XML writer and you could use various commands like
xml.WriteStartElement(...),
xml.WriteValue(..),
xml.WriteEndElement() to construct the XML file dynamically. But there is a problem with this. A file created with such an instance of
XmlWriter (XML) would look like this:
<?xml version="1.0" encoding="utf-8"?><Users><User><Name>user1</Name></User><User><Name>user2</Name></User><User><Name>user3</Name></User></Users>
But, we may expect the XML file to have some line breaks, indentation to make it readable to others. For this, we need to apply some XML writer settings using the "
XmlWriterSettings" class as shown below:
XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
xmlWriterSettings.NewLineOnAttributes = true;
xmlWriterSettings.Indent = true;
Now the
XmlWriter would be instantiated as:
XmlWriter xml = XmlWriter.Create(path, xmlWriterSettings);
With this, the XML generated would be indented, with line breaks as appropriate! Check out the final output after the additional settings:
<?xml version="1.0" encoding="utf-8"?>
<Users>
<User>
<Name>user1</Name>
</User>
<User>
<Name>user2</Name>
</User>
<User>
<Name>user3</Name>
</User>
</Users>
