Examples with XML com.ibm.streams.operator.types.XML used on opensource projects

Example 1 with XML

use of com.ibm.streams.operator.types.XML in project streamsx.topology by IBMStreams.

the class XMLTupleTest method testConstant.

@Test
public void testConstant() throws Exception {
    final Topology topology = newTopology();
    String sdata = "<book><title>Dracula</title><author>Bram Stoker</author></book>";
    byte[] data = sdata.getBytes(StandardCharsets.UTF_8);
    XML xml = ValueFactory.newXML(new ByteArrayInputStream(data));
    TStream<XML> source = topology.constants(Collections.singletonList(xml)).asType(XML.class);
    assertNotNull(source);
    assertEquals(XML.class, source.getTupleClass());
    TStream<String> out = convertXMLToString(source);
    completeAndValidate(out, 10, sdata);
}

Example 2 with XML

use of com.ibm.streams.operator.types.XML in project streamsx.topology by IBMStreams.

the class PublishSubscribeTest method testPublishXML.

@Test
public void testPublishXML() throws Exception {
    TStream<String> source = source();
    source = source.transform(s -> "<a>" + s + "</a>");
    TStream<XML> xml = source.transform(v -> {
        try {
            return ValueFactory.newXML(new ByteArrayInputStream(v.getBytes(StandardCharsets.UTF_8)));
        } catch (IOException e) {
            return null;
        }
    }).asType(XML.class);
    xml.publish("testPublishXML");
    TStream<XML> subscribe = source.topology().subscribe("testPublishXML", XML.class);
    TStream<String> strings = subscribe.transform(v -> {
        byte[] data = new byte[100];
        InputStream in = v.getInputStream();
        int read;
        try {
            read = in.read(data);
        } catch (IOException e) {
            return null;
        }
        return new String(data, 0, read, StandardCharsets.UTF_8);
    });
    strings = strings.transform(s -> s.substring(3, s.length() - 4));
    checkSubscribedAsStrings(strings);
}

Example 3 with XML

use of com.ibm.streams.operator.types.XML in project streamsx.topology by IBMStreams.

the class PublishSubscribeTest method testFilterOnXML.

@Test(expected = IllegalArgumentException.class)
public void testFilterOnXML() throws Exception {
    final Topology t = new Topology();
    TStream<XML> xmls = t.constants(Collections.<XML>emptyList()).asType(XML.class);
    ;
    xmls.publish("sometopic", true);
}
