JDOM is an in-memory XML model that can be used to read, write, create and modify XML Documents. JDOM is similar to DOM in that they both provide an in-memory XML document model.
- DOM is designed to work the same in multiple languages (C, C++, ECMAScript, Java, JScript, Lingo, PHP, PLSQL, and Python),
- JDOM is designed only for Java and uses the natural Java-specific features that the DOM model avoids. For this reason JDOM intentionally does not follow the w3c DOM standard. JDOM is not an XML parser but it can use a SAX, StAX or DOM parser to build the JDOM document. JDOM versions since JDOM 2.0.0 (JDOM2) all use the native language features of Java6 and later like Generics, Enums, var-args, co-variant return types, etc.

Unlike DOM available in JDK , JDOM you have to download the library to use:
You can download the JDOM2 library at homepage:
Or simply download from Maven Repository:
