Appending Data in XML File using JAXB

Question

I need to write the 50,000 records into XML file. But at a time i need to write only 1000 records into XML. How do i append the data into XML using JAXB.

Answer 1

I have tried but the data is written in the following way:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Users xmlns="http://www.yyyy.com/umc/importer/jaxb">
<User id="101" xmlns="">
<username>gjhs</username>
<password>hdfhhdf</password>
<role>df</role>
<email>sdd</email>
<phone>sdfdf</phone>
<description>shkl</description>
<property name="ernnker" value="hkdfhk"/>
</User>
</Users>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Users xmlns="http://www.yyyy.com/umc/importer/jaxb">
<User id="101" xmlns="">
<username>gjhs</username>
<password>hdfhhdf</password>
<role>df</role>
<email>sdd</email>
<phone>sdfdf</phone>
<description>shkl</description>
<property name="ernnker" value="hkdfhk"/>
</User>
</Users>
If i can eliminate the following lines from the above files then my job is done:
</Users>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Users xmlns="http://www.yyyy.com/umc/importer/jaxb">
