XML file changing using regex by Java and apache commons - Made Easy

We need to download commons io 2.4 for the related java code.

Commons IO 2.4 (requires JDK 1.6+)

Commons IO 2.4 is the latest version and requires a minimum of JDK 1.6 - Download now!

XML File: DataInputFile.xml

<? Xml version = "1.0" encoding = "UTF-8"?>
<LayoutDef xmlns: intramart = "http://intramart/maskat/1.0.0" xmlns: dojo = "http://maskat.sourceforge.jp/widget/dojo/1.0.0">
  <Layout name = "dataMapper">
  </ Layout>
</ LayoutDef>
