Remarks
Note
The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.
This property can be changed and takes effect after the next Read call.
When EntityHandling is set to ExpandCharEntities, attribute values are only partially normalized. The reader normalizes each individual text node independently from the content of adjacent entity reference nodes.
To illustrate the difference between the entity handling modes consider the following XML:
<!DOCTYPE doc [<!ENTITY num "123">]>
<doc> A # </doc>
When EntityHandling is set to ExpandEntities the "doc" element node contains one text node with the expanded entity text:
| Depth | NodeType | Name | Value |
|---|---|---|---|
| 1 | Text | A 123 |
When EntityHandling is set to ExpandCharEntities, and WhitespaceHandling is set to Significant or All, the "doc" element expands the character entity and returns the general entity as a node:
| Depth | NodeType | Name | Value |
|---|---|---|---|
| 1 | Text | A | |
| 1 | EntityReference | num | |
| 1 | SignificantWhitespace |
