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

Syntax

C++

public:
XPathDocument(
	XmlReader^ reader,
	XmlSpace space
)

Parameters

reader: Type: System.Xml::XmlReader^
The XmlReader object that contains the XML data.

space: Type: System.Xml::XmlSpace
An XmlSpace object.

Exceptions

Exception	Condition
XmlException	An error was encountered in the XML data. The XPathDocument remains empty.
ArgumentNullException	The XmlReader object parameter or XmlSpace object parameter is null.

Remarks

The XmlSpace object passed as a parameter specifies whether to preserve white space. Default preserves only significant white space; Preserve preserves all white space. By default, the XmlSpace object is set to Default.
The functionality of the XPathDocument constructor is identical to that of the XPathDocument constructor, except for the white space handling options described.
