Enumeration Type Documentation

XmlCaseOrder

enum class System::Xml::XPath::XmlCaseOrder

strong

Specifies the sort order for uppercase and lowercase letters.

Enumerator
None	Ignore the case.
UpperFirst	Uppercase letters are sorted before lowercase letters.
LowerFirst	Lowercase letters are sorted before uppercase letters.

XmlDataType

enum class System::Xml::XPath::XmlDataType

strong

Specifies the data type used to determine sort order.

Enumerator
Text	Values are sorted alphabetically.
Number	Values are sorted numerically.

XmlSortOrder

enum class System::Xml::XPath::XmlSortOrder

strong

Specifies the sort order.

Enumerator
Ascending	Nodes are sorted in ascending order. For example, if the numbers 1,2,3, and 4 are sorted in ascending order, they appear as 1,2,3,4.
Descending	Nodes are sorted in descending order. For example, if the numbers 1,2,3, and 4 are sorted in descending order, they appear as, 4,3,2,1.

XPathNamespaceScope

enum class System::Xml::XPath::XPathNamespaceScope

strong

Defines the namespace scope.

Enumerator
All	Returns all namespaces defined in the scope of the current node. This includes the xmlns:xml namespace which is always declared implicitly. The order of the namespaces returned is not defined.
ExcludeXml	Returns all namespaces defined in the scope of the current node, excluding the xmlns:xml namespace. The xmlns:xml namespace is always declared implicitly. The order of the namespaces returned is not defined.
Local	Returns all namespaces that are defined locally at the current node.

XPathNodeType

enum class System::Xml::XPath::XPathNodeType

strong

Defines the XPath node types that can be returned from the XPathNavigator class.

Enumerator
Root	The root node of the XML document or node tree.
Element	An element, such as <element>.
Attribute	An attribute, such as id='123'.
Namespace	A namespace, such as xmlns="namespace".
Text	The text content of a node. Equivalent to the Document Object Model (DOM) Text and CDATA node types. Contains at least one character.
SignificantWhitespace	A node with white space characters and xml:space set to preserve.
Whitespace	A node with only white space characters and no significant white space. White space characters are '\x20', '\x0d', '\x0a', '\x09'.
ProcessingInstruction	A processing instruction, such as <?pi test?>. This does not include XML declarations, which are not visible to the XPathNavigator class.
Comment	A comment, such as .
All	Any of the XPathNodeType node types.

XPathResultType

enum class System::Xml::XPath::XPathResultType

strong

Specifies the return type of the XPath expression.

Enumerator
Number	A numeric value.
String	A String value.
Boolean	A Boolean true or false value.
NodeSet	A node collection.
Navigator	A tree fragment.
Any	Any of the XPath node types.
Error	The expression does not evaluate to the correct XPath type.
