XmlReader.Skip Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Skips the children of the current node.

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

Syntax

'Declaration
Public Overridable Sub Skip

public virtual void Skip()

Remarks

In the following XML input if the reader is positioned on the <a> node or any of its attributes, calling Skip positions the reader to the <b> node.

If the reader is positioned on a leaf node already (such as the <x> node or the text node abc), calling Skip is the same as calling Read.

 <a name="bob" age="123">
  <x/>abc<y/>
 </a>
 <b>
 ...
 </b>

This method checks for well-formed XML.

The XmlReader implementation determines whether or not the Skip method will expand external entities. The following table describes whether the external entities are expanded for the various types of XmlReader objects.

Type of XmlReader

Expands external entities

XmlReader instance created by the Create method that is reading text data.

No.

XmlReader instance created by the Create method that is reading binary data.

Not applicable.

XmlReader instance wrapped around another XmlReader instance.

Depends on the implementation of the underlying XmlReader. (The Skip method on the underlying XmlReader is called).
