klyn.io.xml.xpath.DOMXPathEvaluator.selectNodes
method

    public selectNodes(expression as String, contextNode as Node, resolver as XPathNSResolver = null) as NodeList throws XPathException, DOMException:

Description

Evaluates an XPath expression and returns the matching nodes as a DOM `NodeList`.

This is a Klyn convenience method. The standard DOM XPath API still uses `evaluate(...)` and `XPathResult`.

Parameters

- expression XPath expression selecting nodes.
- contextNode Context node.
- resolver Namespace resolver, or `null`.

Returns

Matching nodes in document order.

Throws

- XPathException if the expression cannot be converted to a node set.
- DOMException if the context node is invalid.

Example

    nodes = DOMXPathEvaluator().selectNodes("/Spies/Spy", document)
    print(nodes.length)
