Hi,
I am working on the same part of the logic and got stuck here. The above code will work for linux, but I am working on windows platform.
I have seen in the post that you already gave such an example in the previous post, I searched for it but could not find it.
Can you please send me the link to that post or else if you can help me with the same in windows, that would be really great.
Thanks!!
Hi,
I am presently trying to display an XML document as a tree structure.
I am able to do it using JTree and SAX Parser.
Now I would like to get the parents of all non-leaf nodes and display them as sub-trees.
Does we have any function in JTree where I can retrieve the parents of non-leaf nodes and display them??
Please help.
Thanks!!
Thanks for replying to my queries.
I have one more question.
1. Is it possible for me to display only the tree structure without displaying the leaf nodes (I dont want to also display the root node)
2. I just want to get all the non-leaf nodes without the root node and display all non-leaf nodes(not needed in tree form)
Do we have any functions for retrieving the non-leaf nodes from the given tree?
Please help!!
Thanks!!
Sorry......the code given above could not display properly. So I am resending the code back in proper form.

Thanks for the reply. But by doing the above I will be able to modify the original tree that I have and will not be able to display the original tree that I have.
How can I display the subtree in another window or frame such that my original tree is preserved??
Please help me out in this.....
Thanks!!!

I am converting a given html document into a tree structure and displaying it using JTree and DefaultMutable classes.
By using the html parser and the JTree functionality, I can display the html doc as tree structure, but now I would like to get the subtrees only of that tree when clicked on any of the nodes in the tree or else If I input the node, I need to display only the subtree associated with that node and not the entire tree. Is there any function to do that or else if I need to parse with along the tree structure, How can I do that and what functions and classes are available for that.
Any help is appreciated.
Thanks!!!
Hi,
I have a small question.
How do I compute the number of files(which are specific such as .doc) in a directory in C++.
For example, if I have 10 files of type .doc format in a directory, how do I compute this value using C++.
Any help is appreciated.
Thanks!!
HI..
