Java - 파이프로 구분 된 텍스트 파일을 XML로 변환

Question

파이프로 구분 된 텍스트 파일을 Java의 XML로 변환하는 데 사용할 수있는 방법이 있는지 궁금합니다. I 변환 찾고 구분 된 파일 형식으로되어 있습니다 :

RefNo | Location | Name | Age 
123  | North America | Steve | 32 

그리고로 변환 찾고 있어요 :

<data> 
    <RefNo>123</RefNo> 
    <location>North America</location> 
    <name> Steve </name> 
    <age> 32 </age> 
</data>
