XmlReader.MoveToContent Method

Checks whether the current node is a content (non-white space text, CDATA, Element, EndElement, EntityReference, or EndEntity) node. If the node is not a content node, the reader skips ahead to the next content node or end of file. It skips over nodes of the following type: ProcessingInstruction, DocumentType, Comment, Whitespace, or SignificantWhitespace.

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

public virtual XmlNodeType MoveToContent()

Return Value

Type: System.Xml.XmlNodeType
The NodeType of the current node found by the method or XmlNodeType.None if the reader has reached the end of the input stream.

ExceptionCondition
XmlException

Incorrect XML encountered in the input stream.

If the current node is an attribute node, this method moves the reader back to the element that owns the attribute.

This is useful when you want to write code that can skip over random XML markup without breaking. For example, suppose you have the following code:

if (reader.MoveToContent() == XmlNodeType.Element && reader.Name == "price") 
 {
    _price = reader.ReadString();
 }
if (reader->MoveToContent() == XmlNodeType::Element && reader->Name->Equals(S"price")) 
 {
    _price = reader->ReadString();
 }

This code can handle the following inputs without breaking:

<price>123.4</price>

and

<?xml version="1.0"><!DOCTYPE price SYSTEM
  "abc"><price>123.4</price>

and

<?xml version="1.0"><!DOCTYPE price SYSTEM "abc"
  [<!ENTTIY p
  "123.4">]><price>&p;</price>

and

<!-- some test comment --><?processing
  instruction?><price>123.4</price>
