Data Graph Java

[antonello12]

Hello, I have to implement the Data Graph in Java from an XML database, data structures such as I recommended in order to make effective the next navigation? thanks

Might be just me, but your post makes next to no sense. Please elaborate

I'll try to explain myself better, I must start from an XML document as:

<movie>
<title> Hello </ title>
<actors>
<actor> Brad Pitt </ actor>
<actor> George Clooney </ actor>
</actors>
</movie>

and build an internal representation of the document in the form of a graph, where elements are represented as nodes and links between elements such as arches. Then I have to navigate through the graph to process the data. I wanted to understand what are the most efficient structures for the representation of a graph, ie Hashtable, matrices, etc. ...

Draw out a simple xml document, you will find a tree is most pertinent. See The XML data model
There are java libraries that do all this for you, for instance in the javax.xml.parsers package.
