Is there any widget to display an XML file as an expandable/collapsable tree in GWT?

You might take a look at ext gwt the asyncXmlTree might be what you are looking for.

You might take a look at ext gwt, the asyncXmlTree might be what you are looking for. //EDIT// In reply to your comment: I know now what you are looking for. I don't know if this exists, but it shouldn't be to difficult to adapt the code of the asyncXmlTree.

If you look at the sourcecode of the example, you see that the data is returned by a DataReader. You can implement your own that returns not only the content, but also the xml tags. You could look at the code of the XmlReader for an example.

I'm using GXT (which is ext gwt, now renamed to sencha) in my project and I know that widget, but that's not what I want. From the documentation, that's a widget... "... which loads its children on demand using a remote service which returns xml. " I don't want to load the contents of the tree as XML from a remote service, I just want to display an XML file in the tree.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
