| ==Usage notes==
| |
| <ul>
| |
| <li>An <var>XmlParseErrorReason</var> enumeration may have one of the following values, each of which is demonstrated in the [[#Example|examples]] below.
| |
| <dl>
| |
| <dt><var>InvalidUnicodeCharacter</var>
| |
| <dd>The Unicode input contains an invalid character.
| |
| <dt><var>InvalidUTF8Encoding</var>
| |
| <dd>The input UTF8 stream is invalid.
| |
| <dt><var>InvalidUTF16Encoding</var>
| |
| <dd>The input UTF16 stream is invalid.
| |
| <dt><var>SyntaxError</var>
| |
| <dd>A violation of the syntax of an XML document.
| |
| <dt><var>UntranslatableEBCDIC</var>
| |
| <dd>The EBCDIC input contains a character that is not translatable to Unicode.
| |
| <dt><var>UntranslatableISOn</var>
| |
| <dd>The ISO-8859-n input contains a character that is not translatable to Unicode.
| |
| <dt><var>UntranslatableUnicode</var>
| |
| <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.

| |
| <ol><li>
| |
| The following template is used to apply the <var>[[LoadXml_(XmlDoc/XmlNode_function)|LoadXml]]</var> deserialization method to a series of test ''input-string'' values to demonstrate the <var>XmlParseError</var> exception output:
