BE THE CODER > XML > XOM Examples > Remove Child by Index

XOM (XML Object Model) is a tree based java API for processing XML by taking the best ideas from SAX and DOM. It is simple, fast and easy to use. This requires the library xom-1.2.7.jar to be in classpath. The following example shows removing a child element from parent by index.
