Validating an xml document

You can also use the Get Element By Id to retrieve nodes.To use this approach, you’ll have to define ID’s in the document type definition declarations of your XML file.
This example creates a book node, adds attrubutes to that node, and then adds that node to the document. When a user chooses a book and presses an up or down button, your code could call methods like these to position the corresponding book node before or after other book nodes.
Note also that this method loads an entire DOM tree into memory, see comments for alternatives if you want to save on RAM.
What you are asking is how to verify that a piece of content is well-formed XML document.
To get a validating parser, or one that understands name spaces (or both), you can configure the factory to set either or both of those options using the following code.
Note - JAXP-conformant parsers are not required to support all combinations of those options, even though the reference parser does.
The only caveat is that this requires that you have 3-5x as much memory available as raw size of the input document.
To get around this limitation you could use a streaming parser, such as Woodstox (which implements standard Stax API). Not only can you validate the documents structure, but you can supply some pretty complex rules about what type of content your nodes and attributes can contain.
If so, you would create an XMLStream Reader, and just call "reader.next()" as long as "Next()" returns true.
The Document Object Model provides APIs that let you create, modify, delete, and rearrange nodes.
This is easily done by simply letting an XML parser (try to) parse content in question -- if there are issues, parser will report an error by throwing exception.
There really isn't anything more to that; so all you need is to figure out how to parse an XML document.
Before you try to create a DOM, it is helpful to understand how a DOM is structured.
