XElement class
https://docs.microsoft.com/zh-cn/dotnet/api/system.xml.linq.xelement?view=netframework-4.8
Represents an XML element.
The following example creates an XML tree. The content of the new element comes from the LINQ query.
Dim xmlTree1 As XElement = _
<Root>
<Child1>1</Child1>
<Child2>2</Child2>
<Child3>3</Child3>
<Child4>4</Child4>
<Child5>5</Child5>
<Child6>6</Child6>
</Root>
Dim xmlTree2 As XElement = _
<Root>
<%= From el In xmlTree1.Elements() _
Where el.Value >= 3 And el.Value <= 5 _
Select el %>
</Root>
Console.WriteLine(xmlTree2)
This example produces the following output:
<Root>
<Child3>3</Child3>
<Child4>4</Child4>
<Child5>5</Child5>
</Root>

Dim root As New XElement("Company", _
New XAttribute("Type", "Publisher"), _
New XElement("CompanyName", "Wrox"), _
New XElement("CompanyAddress", _
New XElement("Street", "111 River Street"), _
New XElement("city", "Hoboken"), _
New XElement("State", "NJ"), _
New XElement("Counttr", "USA"), _
New XElement("Zip", "07030-5774")))
