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.
Assembly: System.Xml (in System.Xml.dll)
| Exception | Condition |
|---|---|
| XmlException | Incorrect XML encountered in the input stream. |
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->Equals( "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>
