Interface XPathExpression

public interface XPathExpression

Creation

Instances of X Path Expression objects can be created using the following factory style method(s).

XPathExpression object = createXPathExpression(
    contexts,
    value);

XPathExpression object = createXPathExpression(
    namespaceContexts,
    value);

<core:XPathExpression xmlns:core="http://xmlns.oracle.com/irm/core">
<namespaceContexts xmlns:example1="http://www.example.com">example1:e1</namespaceContexts>
<namespaceContexts xmlns:example2="http://www.example2.com">example2:e2</namespaceContexts>
<value>e1:node[@name='hello']</value>
