27 * The XmlValidationError class extends the {@link XmlError }XMLError class. The XML Validator contains
28 * extra attributes that can be used to construct the XML validation error programatically.
29 * <p>
30 * To extract the validation error cast the errors to XmlValidationError instead of
31 * XmlError for example:
32 * <br/>
33 * <pre>
34 * xobj.validate(new XmlOptions().setErrorListener(errors))
35 * for (Iterator it = errors.iterator(); it.hasNext(); )
36 * {
37 * XmlError err = (XmlError)it.next());
38 * if (err instanceof XmlValidationError)
39 * {
40 * XmlValidationError validationError = (XmlValidationError) err;
41 * }
42 * }
43 *</pre>
44 *
45 *
46 * Whenever an XmlValidationError is retrieved it will always be populated with
47 * the following information:
48 * <ul>
49 * <li>Message</li>
50 * <li>Severity</li>
51 * <li>Error Type </li>
52 * </ul>
53 *
54 * <p>
55 * The error type is very important because the other attributes of the
56 * XMLValidationError are populated based on the error type.
57 * </p>
58 * if errortype == INCORRECT_ELEMENT then
59 * <br/>
60 * offendingQName, badSchemaType will always be present, however expectedSchemaType and
61 * expectedQNames are available only if it is possible to determine them during vaildation.
62 *<br/>
63 *
64 * <p>
65 * if errortype == ELEMENT_NOT_ALLOWED then
66 * <br/>
67 * badSchemaType will always be present, however expectedSchemaType and
68 * offendingQName are available only if it is possible to determine them during vaildation.
69 * <br/>
70 *
71 * <p>
72 * if errortype == INCORRECT_ATTRIBUTE then
73 * <br/>
74 * offendingQName, badSchemaType will always be present
75 * <br/>
76 *
77 * <p>
78 * if errortype == ATTRIBUTE_TYPE_INVALID then
79 * <br/>
80 * no other addtional attributes are populated
81 * <br/>
82 *
83 * <p>
84 * if errortype == LIST_INVALID then
85 * <br/>
86 * expectedSchemaType will always be present
87 * <br/>
88 *
89 * <p>
90 * if errortype == UNION_INVALID then
