Example 6 with XPathBuilder

use of org.apache.camel.builder.xml.XPathBuilder in project camel by apache.

the class XPathTest method testXPathUsingSaxon.

@Test
public void testXPathUsingSaxon() throws Exception {
    XPathFactory fac = new XPathFactoryImpl();
    XPathBuilder builder = XPathBuilder.xpath("foo/bar").factory(fac);
    // will evaluate as XPathConstants.NODESET and have Camel convert that to String
    // this should return the String incl. xml tags
    String name = builder.evaluate(context, "<foo><bar id=\"1\">cheese</bar></foo>", String.class);
    assertEquals("<bar id=\"1\">cheese</bar>", name);
    // will evaluate using XPathConstants.STRING which just return the text content (eg like text())
    name = builder.evaluate(context, "<foo><bar id=\"1\">cheese</bar></foo>");
    assertEquals("cheese", name);
