For finding a specific node, theSelectSingleNodemethod is used. If there are multiple nodes matching your search criteria, then theSelectSingleNodereturns the first node that matches the search criteria, navigating from top of the tree down, in document order. To retrieve multiple nodes into a node...
Select is a more specific method in that it assumes that the return type is a node-set and inserts the nodes in an iterator. Sorting the Node-Set An interesting extension built into the XPathExpression class is the ability to sort the node-set before it gets passed back to the caller. ...

The pagination query function supports query based on multiple filter criteria, meaning that each query can contain more than one filter criterion. For example, the following expression contains two filter criteria, indicating that the 10GE port data of nodes 1 to 100 is queried. select="/ifm:...
Many XPath expressions select a set of nodes. In essence, they return a node-set. One function does that, too. The id(...) function returns the node with the specified ID. (Elements have an ID only when the document has a DTD, which specifies which attribute has the ID type). Posit...
public classXPathProcess extendsProcess Extends the pipeline Process class to select node(s) from an XML Document or an XML DocumentFragment, given an XPath pattern. Multiple XPath nodes selected would become a DocumentFragment and a single XPath Node would be converted into an XML Doucument. Henc...
The selectNodes method takes a string expression (either XPath 1.0 or XSL Pattern) and returns a reference to an IXMLDOMNodeList interface representing the collection of nodes matching the expression. The following code snippet illustrates the use of selectNodes in Visual Basic®: Expand table...
