Examples of JXPathExtractor

org.mule.module.xml.transformer.JXPathExtractor
The JXPathExtractor is a simple transformer that evaluates an xpath expression against the given bean and that returns the result.
By default, a single result will be returned. If multiple values are expected, set the {@link #singleResult} property to false. In this case a{@link List} of values will be returned. Note the property is currently ignoredfor non-String/XML payloads.

Examples of org.mule.module.xml.transformer.JXPathExtractor

        getAndTestTransformer("domToXml", DomDocumentToXml.class);
    }


    public void testJXPathExtractor()
    {
        JXPathExtractor extractor = (JXPathExtractor) getAndTestTransformer("jxpathExtractor",
            JXPathExtractor.class);
        assertEquals("/expression", extractor.getExpression());
        assertFalse(extractor.isSingleResult());
        assertEquals(JXPathExtractor.OUTPUT_TYPE_VALUE, extractor.getOutputType());
        
        Map ns = extractor.getNamespaces();
        assertNotNull(ns);
        
        assertEquals("http://foo.com", ns.get("foo1"));
        assertEquals("http://foo.com", ns.get("foo2"));
