Extensions.XPathSelectElements Method (XNode, String)

Selects a collection of elements using an XPath expression.

Namespace:  System.Xml.XPath
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

static member XPathSelectElements : 
        node:XNode * 
        expression:string -> IEnumerable<XElement> 

Parameters

node
Type: System.Xml.Linq.XNode

The XNode on which to evaluate the XPath expression.

expression
Type: System.String

A String that contains an XPath expression.

Return Value

Type: System.Collections.Generic.IEnumerable(XElement)
An IEnumerable(T) of XElement that contains the selected elements.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type XNode. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Although the ordering of returned collections is not specified in the XML XPath Language 1.0 Recommendation, this extension method returns nodes in document order.

Note that nodes are returned in document order even when you use a reverse axis, such as preceding-sibling or ancestor-or-self.

The following example creates a small XML tree and uses XPathSelectElements to select a set of elements.

No code example is currently available or this language may not be supported.

This example produces the following output:

<Child2>4</Child2>
<Child2>5</Child2>
<Child2>6</Child2>
