Remarks

This interface uses XPath, a way to select a node or groups of nodes that match a selection criteria, as parameters in several methods and properties (CountX property, DeleteProperty method, SetAttribute method, SetPropertyX method, and SimpleGetProperty method).  XPath provides a simple query language for identifying nodes in an XML document based on attribute, name, and values. 

An important point when using XPath is that the names of properties and attributes, as well as the values of both, are case sensitive. Also, because metadata always has a <metadata> root node, it can be omitted from patterns used with this interface. For example, "/metadata/node/subnode" should just be "node/subnode".

Some basic examples of XPath include:

For more examples of XPath, see the MSDN article, XPath Examples.

When using this interface on a newly-created XmlPropertySet, the property set should be cast to the IXmlPropertySet2 interface and the InitGeneric method should be called. See the XmlPropertySet coclass documentation for more information.
