JAXB Unmarshalling resulted in SAXParser Exception

I tried to unmarshall the xml resulted in saxparser exception because the value of a element has a tag element which is not properly closed. It is what I get and have to process.

Here is the sample xml - 

<GetResultResponse>
  <ExecutionID>17716868</ExecutionID>
  <Device>STLMJWB</Device>
  <Status>Success</Status>
  <ResultSet>
    <Command>RTRV-ALM-ALL:STLMJWB0201000003FIS:ALL:<ctag=dq>;</Command>
    <CommandType>Raw</CommandType>
    <commandResult>Success</commandResult>
  <ResultSet>
</GetResultResponse>

The above xml contains along with other string as value of command and the tag is not properly closed resulting in the following exception -

[org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 212; Element type "ctag" must be followed by either attribute specifications, ">" or "/>".]

The xml input to unmarshall is fed as string reader

StringReader sr = new StringReader("ABOVE XML");
unmarshaller.unmarshal(sr);

I have two classes - One for GetResultResponse and other for ResultSet.

Things I tried to sort out - 1. CharacterEscapeHandler - Got error when I assigned this proerpty to Unmarshaller because only marshaller accepts this. 2. XmlJavaTypeAdapter - Unmarshalling happens before processing and returning values from Adapter. 3. BeforeUnmarshall - Set listener to unmarshaller; Returns null for command. 4. XmlMixed and XmlAnyElement - Expects proper closing tag.

Pleae let me know if you have any doubts. Thanks in Advance

Your XML as it currently is, is not valid. You need to properly escape the text content here:

<Command>RTRV-ALM-ALL:STLMJWB0201000003FIS:ALL:<ctag=dq>;</Command>

As

<Command>RTRV-ALM-ALL:STLMJWB0201000003FIS:ALL:&lt;ctag=dq>;</Command>
