XML:
<CONTACTS>
<Contact ContactID=”2″>
<FirstName=”Arpit”/>
<LastName=”Gupta”/>
</CONTACTS>
XELEMENT: (located in System.xml.linq)
XElement xml = new XElement(“CONTACTS”, new XElement(“Contact”, new XAttribute(“ContactID”,”2″), new XAttribute(“FirstName”,”Arpit”), new XAttribute(“LastName”,”Gupta”)));
C# Code :
Loads XML from a local file into an XDocument Object
XDocument xmlDoc = XDocument.Load(@”C:sites.xml”);
Var q = from c in xmlDoc.Descendants(“site”)
select (string)c.Element(“name”) + “–” + (string)c.Element(“url”);
foreach (string name in q)
{
console.writeline(“site:” + name);
}
XML:
<Sites>
<site technical=”true”>
<name>Arpit</name>
<url>good2seeu.wordpress.com</url>
</site>
<site technical=”true”>
<name>Arpit_ABC</name>
<url>google.com</url>
</site>
</Sites>
XDocument is used to select the items to display VIA “Descendants” property in the “from” clause. Finally, “foreach” block is used to loop through every Element loaded via “select” statement and displayed via “console” object.
Filter VIA Where Clause:
Code snippets selects and display only those site elements with “TRUE” valus in its Technical Attributes.
XDocument XDoc = XDocument.load(@”C:Sites.xml”);
Var q= from c in XDoc.Descendants(“site”)
where c.Attribute(“Technical”).Value = “true”
select (string)c.Element(“name”) + “==>” + (string)c.Element(“url”);
foreach(string name in q)
{
console.writeline(“site:” + name);
}
