public class XPathNormalizerWithXPath
extends XPathNormalizer

A XPathNormalizer that generates normalized path expressions by using an XPath expression that is evaluated on the context node in question.

The context item on which the XPath will be evaluated, is determined by XPathRewriterBase.getTextNodeAtPosition(S9ApiResource, String, int, Mode). This is generally a text node.

Field Details

PATH_FUNCTION_XPATH

public static final String PATH_FUNCTION_XPATH

An XPath expression suitable for normalizing path expressions to nodes.

Generates a path expression using the path(.) XPath function. This result in a path expression stepping from the root element to the context node. Element names are QNames in Clark notation.

• Constant Field Values

FROM_ROOT_CLARK_XPATH

public static final String FROM_ROOT_CLARK_XPATH

An XPath expression suitable for normalizing path expressions to nodes.

Generates a simple path expression stepping from the root element to the context node. Element names are QNames in Clark notation.

• Constant Field Values

FROM_DEEPEST_ID_CLARK_XPATH

public static final String FROM_DEEPEST_ID_CLARK_XPATH

An XPath expression suitable for normalizing path expressions to nodes.

Generates a path expression stepping from the deepest element with an XML-ID (@xml:id) to the context node. Element names are QNames in Clark notation.

Method Details

getNormalizedXPath

protected String getNormalizedXPath(DOMResource resource,
 net.sf.saxon.s9api.XdmNode node,
 boolean escaped)
                             throws SelectorException

Get the path to the XdmNode given as parameter by using the XPath expressing the normalizer was initialized with.

Specified by:

getNormalizedXPath in class XPathNormalizer

Parameters:

node - an XdmNode to which the normalized path must be generated to

escaped - whether or not the normalized XPath is to be escaped for X-processing, e.g., ' escaped to '.

Returns:

the normalized XPath expression as a String

Throws:

SelectorException
