Following are some of the options to do the same

1. Using XmlDocument

C#

XmlDocument doc = new XmlDocument();
doc.Load("D:\\build.xml");
XmlNode root = doc.DocumentElement; 
XmlNode myNode = root.SelectSingleNode("galleries::folder");
myNode.Value = "blabla";
doc.Save("D:\\build.xml");

2. You can also use LINQ to do the same

C#

using System.Xml.Linq;  
XDocument xmlFile = XDocument.Load("D:\\build.xml");  
var query = from c in xmlFile.Elements("galleries").Elements("folder")                 
select c;  foreach (XElement folder in query)  
{
	folder.Attribute("attr1").Value = "MyNewValue"; 
} 
xmlFile.Save("build.xml");
