XML Child Axis Property (Visual Basic)

Provides access to the children of one of the following: an xref:System.Xml.Linq.XElement object, an xref:System.Xml.Linq.XDocument object, a collection of xref:System.Xml.Linq.XElement objects, or a collection of xref:System.Xml.Linq.XDocument objects.

Syntax

object.<child>

Parts

Term Definition
object Required. An xref:System.Xml.Linq.XElement object, an xref:System.Xml.Linq.XDocument object, a collection of xref:System.Xml.Linq.XElement objects, or a collection of xref:System.Xml.Linq.XDocument objects.
.< Required. Denotes the start of a child axis property.
child Required. Name of the child nodes to access, of the form [prefix:]name.

- Prefix - Optional. XML namespace prefix for the child node. Must be a global XML namespace defined with an Imports statement.
- Name - Required. Local child node name. See Names of Declared XML Elements and Attributes.
> Required. Denotes the end of a child axis property.

Return Value

A collection of xref:System.Xml.Linq.XElement objects.

Remarks

You can use an XML child axis property to access child nodes by name from an xref:System.Xml.Linq.XElement or xref:System.Xml.Linq.XDocument object, or from a collection of xref:System.Xml.Linq.XElement or xref:System.Xml.Linq.XDocument objects. Use the XML Value property to access the value of the first child node in the returned collection. For more information, see XML Value Property.

The Visual Basic compiler converts child axis properties to calls to the xref:System.Xml.Linq.XContainer.Elements%2A method.

XML Namespaces

The name in a child axis property can use only XML namespace prefixes declared globally with the Imports statement. It cannot use XML namespace prefixes declared locally within XML element literals. For more information, see Imports Statement (XML Namespace).

Example 1

The following example shows how to access the child nodes named phone from the contact object.

[!code-vbVbXMLSamples#17]

This code displays the following text:

Home Phone = 206-555-0144

Example 2

The following example shows how to access the child nodes named phone from the collection returned by the contact child axis property of the contacts object.

[!code-vbVbXMLSamples#18]

This code displays the following text:

Home Phone = 206-555-0144

Example 3

The following example declares ns as an XML namespace prefix. It then uses the prefix of the namespace to create an XML literal and access the first child node with the qualified name ns:name.

[!code-vbVbXMLSamples#19]

This code displays the following text:
