Examples with JXPathContext org.apache.commons.jxpath.JXPathContext used on opensource projects

Example 1 with JXPathContext

use of org.apache.commons.jxpath.JXPathContext in project galley by Commonjava.

the class JXPathContextAncestryTest method basicJXPathTest.

@Test
@Ignore
public void basicJXPathTest() throws Exception {
    final InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream("jxpath/simple.pom.xml");
    final Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(is);
    final JXPathContext ctx = JXPathContext.newContext(document);
    document.getDocumentElement().removeAttribute("xmlns");
    final String projectGroupIdPath = "ancestor::project/groupId";
    // NOT what's failing...just populating the node set to traverse in order to feed the ancestor:: axis test.
    final List<?> nodes = ctx.selectNodes("/project/dependencies/dependency");
    for (final Object object : nodes) {
        final Node node = (Node) object;
        dump(node);
        final Stack<Node> revPath = new Stack<Node>();
        Node parent = node;
        while (parent != null) {
            revPath.push(parent);
            parent = parent.getParentNode();
        }
        JXPathContext nodeCtx = null;
        while (!revPath.isEmpty()) {
            final Node part = revPath.pop();
            if (nodeCtx == null) {
                nodeCtx = JXPathContext.newContext(part);
            } else {
                nodeCtx = JXPathContext.newContext(nodeCtx, part);
            }
        }
        System.out.println("Path derived from context: '" + nodeCtx.getNamespaceContextPointer().asPath() + "'");
        // brute-force approach...try to force population of the parent pointers by painstakingly constructing contexts for all intermediate nodes.
        System.out.println("Selecting groupId for declaring project using path-derived context...");
        System.out.println(nodeCtx.getValue(projectGroupIdPath));
        // Naive approach...this has all the context info it needs to get parent contexts up to and including the document!
        System.out.println("Selecting groupId for declaring project using non-derived context...");
        System.out.println(JXPathContext.newContext(node).getValue(projectGroupIdPath));
    }
}

Example 2 with JXPathContext

use of org.apache.commons.jxpath.JXPathContext in project opennms by OpenNMS.

 */
@Test
@SuppressWarnings("unchecked")
public void testXpath() throws Exception {
    JSONObject json = MockDocumentBuilder.getJSONDocument();
    JXPathContext context = JXPathContext.newContext(json);
    Iterator<Pointer> itr = context.iteratePointers("/zones/zone");
    while (itr.hasNext()) {
        Pointer resPtr = itr.next();
        JXPathContext relativeContext = context.getRelativeContext(resPtr);
        String resourceName = (String) relativeContext.getValue("@name");
        Assert.assertNotNull(resourceName);
        String value = (String) relativeContext.getValue("parameter[@key='nproc']/@value");
        Assert.assertNotNull(Integer.valueOf(value));
    }
}

Example 3 with JXPathContext
