To get the values of the data, you should use some kind of xml parser.

since Java 1.6 you can use JAXB for this task:

@XmlRootElement( name = "PrintLetterBarcodeData" )
@XmlAccessorType(XmlAccessType.FIELD)
public class PrintLetterBarcodeData
{
    enum Gender
    {
        M, F
    }

    @XmlAttribute
    String uid;
    @XmlAttribute
    String name;
    @XmlAttribute
    Gender gender;
    @XmlAttribute( name = "yob" )
    int    yearOfBirth;
    @XmlAttribute
    String co;
    @XmlAttribute
    String street;

    // getters/setters omitted for readability, these should be used in production code
}

private static PrintLetterBarcodeData parse( String xml ) throws JAXBException
{
    Unmarshaller unmarshaller = JAXBContext.newInstance( PrintLetterBarcodeData.class ).createUnmarshaller();

    return (PrintLetterBarcodeData) unmarshaller.unmarshal( new StringReader( xml ) );
}

private static void sample() throws JAXBException
{
    String str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> <PrintLetterBarcodeData uid=\"s3434343\" name=\"sdsdasdasd\" gender=\"M\" yob=\"1991\" co=\"S/sdsds\" street=\"sdsdsdl605\"/>";

    PrintLetterBarcodeData barcodeData = parse( str );

    System.out.println( barcodeData.uid );
    System.out.println( barcodeData.name );
    System.out.println( barcodeData.gender );
    System.out.println( barcodeData.yearOfBirth );
    System.out.println( barcodeData.co );
    System.out.println( barcodeData.street );
}

you can then use it like any normal java object.

How do you put the text into eclipse, pasting from clipboard? In that case try Preferences/Java/Editor/Typing/ "Escape text when pasting into a string literal". If you read String from otyher source you can try with http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringEscapeUtils.html

You need to escape all the double-quotes:

String str="<?xml version=\"1.0\" encoding=\"UTF-8\"?> <PrintLetterBarcodeData uid=\"s3434343\" name=\"sdsdasdasd\" gender=\"M\" yob=\"1991\" co=\"S/sdsds\" street=\"sdsdsdl605\"/>";

What are the errors? It is hard to diagnose it without knowing the errors. However, I can say that you will need a \ character before the quotes inside the XML string.

It would be 

String str= "<?xml version=\"1.0\" encoding=\"UTF-8\"?><PrintLetterBarcodeData uid=\"s3434343\" name=\"sdsdasdasd\" gender=\"M\" yob=\"1991\" co=\"S/sdsds\" street=\"sdsdsdl605\"/>";
