Examples with XmlDeclaration org.jsoup.nodes.XmlDeclaration used on opensource projects

Example 1 with XmlDeclaration

use of org.jsoup.nodes.XmlDeclaration in project jsoup by jhy.

the class XmlTreeBuilderTest method testParseDeclarationAttributes.

@Test
public void testParseDeclarationAttributes() {
    String xml = "<?xml version='1' encoding='UTF-8' something='else'?><val>One</val>";
    Document doc = Jsoup.parse(xml, "", Parser.xmlParser());
    XmlDeclaration decl = (XmlDeclaration) doc.childNode(0);
    assertEquals("1", decl.attr("version"));
    assertEquals("UTF-8", decl.attr("encoding"));
    assertEquals("else", decl.attr("something"));
    assertEquals("version=\"1\" encoding=\"UTF-8\" something=\"else\"", decl.getWholeDeclaration());
    assertEquals("<?xml version=\"1\" encoding=\"UTF-8\" something=\"else\"?>", decl.outerHtml());
}

Example 2 with XmlDeclaration

use of org.jsoup.nodes.XmlDeclaration in project jsoup by jhy.

the class DataUtil method parseByteData.
