Java dom update xml

However, the highlighted line of code below constructs a source object that consists of the subtree rooted at a particular node. In the case below, TranformationApp02 is run on the file foo. At this point, you have seen how to use a transformer to write out a DOM and how to use a subtree of a DOM as the source object in a transformation. In the next section, you will see how to use a transformer to create XML from any data structure you are capable of parsing.

Hi Shahzeb, thank you for your answer, I have got the xml part working. My Answer already does that.

These DOM objects are linked together in a tree structure. The parser reads the whole XML structure into the memory. SAX parsers are event-based; they are faster and require less memory. On the other hand, DOM is easier to use and there are tasks, such as sorting elements, rearranging elements or looking up elements, that are faster with DOM.

DocumentTraversal contains methods that create iterators to traverse a node and its children. NodeFilter is used to filter out nodes. NodeIterator is used to go through a set of nodes. TreeWalker is used to navigate a document tree or subtree using the view of the document defined by their whatToShow flags and filter of the document.

The example parses the users. It utilizes the names of the tags in the code; for instance: elem.
