Example 36 with DSNamespaceContext

use of org.apache.xml.security.test.dom.DSNamespaceContext in project santuario-java by apache.

the class Santuario273Test method testC14n11Base.

@org.junit.Test
public void testC14n11Base() throws Exception {
    DocumentBuilder documentBuilder = XMLUtils.createDocumentBuilder(true);
    documentBuilder.setErrorHandler(new org.apache.xml.security.utils.IgnoreAllErrorHandler());
    Document doc = null;
    try (InputStream is = new ByteArrayInputStream(input.getBytes())) {
        doc = documentBuilder.parse(is);
    }
    Canonicalizer c14n = Canonicalizer.getInstance(Canonicalizer.ALGO_ID_C14N11_OMIT_COMMENTS);
    XPathFactory xpf = XPathFactory.newInstance();
    XPath xPath = xpf.newXPath();
    xPath.setNamespaceContext(new DSNamespaceContext());
    Node signedInfo = (Node) xPath.evaluate("//ds:SignedInfo[1]", doc, XPathConstants.NODE);
    byte[] output = c14n.canonicalizeSubtree(signedInfo);
    assertEquals(new String(output, java.nio.charset.StandardCharsets.UTF_8), expectedResult);
