| ==Usage Notes==
| |
| <ul>
| |
| <li>An XmlParseErrorReason enumeration may have one of the following values,
| |
| each of which is demonstrated in the [[#Example|example below]].
| |
| <dl>
| |
| <dt>InvalidUnicodeCharacter
| |
| <dd>The Unicode input contains an invalid character.
| |
| <dt>InvalidUTF8Encoding
| |
| <dd>The input UTF8 stream is invalid.
| |
| <dt>InvalidUTF16Encoding
| |
| <dd>The input UTF16 stream is invalid.
| |
| <dt>SyntaxError
| |
| <dd>A violation of the syntax of an XML document.
| |
| <dt>UntranslatableEBCDIC
| |
| <dd>The EBCDIC input contains a character that is not translatable to Unicode.
| |
| <dt>UntranslatableISOn
| |
| <dd>The ISO-8859-n input contains a character that is not translatable to Unicode.
| |
| <dt>UntranslatableUnicode
| |
| <dd>The Unicode input contains a character that is not translatable to EBCDIC.
| |
| This exception can be avoided using the <code>AllowUntranslatable</code>
| |
| option of the deserialization method.
| |
| </dl>
| |
| </ul>
| |
| ==Example==
| |
|
| |
| The following template is used to apply the LoadXml deserialization method
| |
| to a series of test ''input-string'' values
| |
| to demonstrate the XmlParseError exception output:
| |
| <p class="code"> Try
| |
| PrintText {~}: {%d:LoadXml(&'italic(input-string))}
| |
| Catch XmlParseError to %err
| |
| Print ' '
| |
| Print 'Error Reason:' And %err:Reason:ToString
| |
| Print 'Error Description:' And %err:Description
| |
| Print 'Error Character Position:' And %err:CharacterPosition
| |
| Print 'Error Input Hex Value:' And %err:InputHexValue
| |
| Print ' - - -'
| |
| End Try
| |
| </p>
| |
|
| |
| These are the results:
