XML to tree structure

Hi guys
Not used Java in a while (or done much programming in a while to be honest) and i've been set the task of reading an XML document into a tree structure but without using any existing XML libraries. I'm a little bit stumped which line to go down and wondered if anyone had could help me out with a few suggestions as to how to tackle it.
Many thanks

yeah i have read the article and i get that i need to read in the first tag as the root and then add the next tag as a node and then its data as a node,Once you write the code to read a node, you just apply it recursively to these other nodes.
then once that tag has closed, back track and the next tag as a node and so on.To back track you should just have to return from your recursive method. Returning from the method implicitly pops a stack thus returning you to the enclosing tag.
But having real trouble making a start on the source code, can't find any good examples to get me started. My coding skills are really rusty.Can you write a simple "Hello world" program? Can you open a file, and read in one line at a time, and count the lines?
Thanks for giving me all this help.

XML with DefaultTreeModel structure

I�m developing an application which uses DefaultTreeModel as one of its major structure...
may I use a XML file as persistence ? May I map directly between the TreeModel and a XML file ?
Actually people around here cited Castor as the solution, but I can�t find in the castor documentation about trees mapping, just Vector, Hashtable and arrays...

I�m thinking like this way:
the XML is a tree structure...
the TreeModel is obviously a tree structure...
then, I should be able to create a Java DefaultTreeModel which reflects the XML file contents..
I�m reading the SUN tutorial ...

Tree structure of portal application in NWDS

Hi all,
Im new to portal applications and I did not under stand the tree structure that appears after we start portal application in ep perspective in NWDS. Especially the PORTAL-INF and src.code in the tree structure .If any body has any relevant information or document about it please send me.

portal applications are same as the Web applications developed in Java, JSP ....
PORTAL-INF is same as the WEB-INF in normal web application structure.
in Web application we create .war file whereas here we create as .par file.
in web application we have web.xml inside WEB-INF folder where as here we have portalapp.xml.
src.core and src.api is used as the source code folder.
You can check this in "Java Build path" if u go to the project properties.
Hope this give u a small idea on portal files structure.
cheers.

Generate Tree Structure from DB - XSQL??

We have a table that contains a tree structure using Parent/Child fields. We use "Connect By" to extract this in normal applications to show in a tree control.
We now want this in XML format output by our web server, where a client side app running in the browser can load this.
I have looked at XSQL utility but it looks to only generate a simple flat structure.
Anyone have an idea of how to automatically create a tree structure straight from the DB?
Thanks
Rob

You downloaded the wrong XML Parser!
XSQL requires Java Parser. Well, there's a copy included with the XSQL package so you actually don't need to do another download.
You really don't need XSQL if you just want a XML file from DB, you just needed a XML SQL Utility. Download that and run the samples.

     Calculation Views
     Unit Operation Views
        Cell Culture Views
        Purification Views
        MFR Views

All the nodes should have folder Icon.

Vishal,
If you structure your data with two columns, the first being the Node name and the second being the Parent node name (see your information below), the iBrowser applet will make a nice data driven tree with all of the SelectionEvent or navigational capabilities you want.
<?xml version="1.0" encoding="UTF-8"?>
<Rowsets DateCreated="2007-05-02T07:37:37" EndDate="2007-05-02T16:59:53" StartDate="2007-05-02T16:59:53" Version="11.5.3">
<Rowset><Columns><Column Description="" MaxRange="1" MinRange="0" Name="NAME" SQLDataType="1" SourceColumn="NAME"/><Column Description="" MaxRange="1" MinRange="0" Name="PARENT" SQLDataType="1" SourceColumn="PARENT"/></Columns>
<Row><NAME>Parent</NAME><PARENT></PARENT></Row>

Loading in tree structure from arraylist

Hi,
I have a ArrayList contains xml file path like
ArrayList al={"/folder1/sub1/sub11/1.xml",
"/folder1/sub1/2.xml,
"/folder1/test1/3.xml",
"/folder2/sub2/4.xml",
"/folder2/sub2/sub3/5.xml"}
Note: 1.This arraylist objects are dynamically loaded.
2.The objects in array list are not file system directory path like (e.g., C:/folder1/sub1/.....). Its string added in arraylist.
using this arraylist i want to load it in jsp tree structure, like
folder1
|___sub1
| |_sub11
| | |__1.xml
| |_2.xml
|___test1
|_3.xml
folder2
|
|_sub2
|___4.xml
|___sub3
|___5.xml
Can any one help me with logic or predefined function in java to iterate each string array object and split parent and sub child folder and load it in tree.
Edited by: manjunath_2284 on Aug 11, 2009 6:04 AM

Create a Node class that has a name and Map<String, Node> as children.
Iterate over the list, split each entry on "/", and place the parts that you get into the Node structure.

Can we change the Bill/Payment tree structure on Control central page?

Can we change the Bill/Payment tree structure on Control central page to Bill/Payment Tree containing a single node for all A/R related activities for a specific bill period, in reverse chronological order. Basically the tree should look like

I have tried changing controlCentralBPTree.xml but if I do that the tree is not expanding its just collapsed I m not able to expand.
So do I need to change some other file to change the tree structure and look like above?

Hello CHS.
I tested your project but to change the label and has not worked.
I tried running the Application Module and test the ViewCriteria, and show correctly the labels defined in control hint of bind variable.
Again, I think the component af:query should do the same, but does not work.
Any Oracle ACE Director some could verify this problem?
thank you very much

Repeating XML in Tree Display

I am using a Data Provider to load an xml file into a Tree
structure. My xml file has repeating nodes of <container> and
<product>, they are nested arbitrarily to reflect a proof of
concept. When I load this file into a Tree structure I get
repeating nodes, however in the original xml file, of course, these
nodes do no appear.
My call to load the xml into a XMLList through a Handler
function is as follows:
[Bindable]
private var dishesDP:XMLList;
private function dishesXMLHandler(event:ResultEvent):void
dishesDP = event.result..container;
The incorrect XML being loaded into my XMLList:
<container title="Pants" description="These go on your
legs">
<container title="Jeans" description="They are blue and
last a long time.">
<product id="1" title="Levi's Denium" description="Nice
normal blue jeans." price="17.50" image="image2.jpg"/>
<product id="2" title="Abercombie" description="Did
someone already wear these?? They got holes in them?" price="24.95"
image="image2.jpg"/>
</container>

wear them to work.">
<product id="3" title="Dockers" description="Boring old

<product id="4" title="Old Navy" description="Cheap

          <mx:HTTPService id="srv" url="http://localhost:8080/SampleWebApp/test.jsp" result="onResult(event)"/>
And treeData as a dataSource for Tree.

Required info on tree structure.

Hi All,
Can any body help me in displaying data in a tree structure in PDA.
We have a requirement where the data comes with parent & child relationship, each child may or may not be a parent and the tree may drill more than 10 levels.
when user clicks on the node all the subsequent childs need to be displayed and on the second click the tree need to be collapsed to that node level.(this should be similar to some of the data in sap ex: functional locations)
IS there a component in MI / MAM application to acheive the same else what is the possible way for this.
Your help will be well appriciated.
Thanks & Regards,
Sai.K. K

Hi Sai,
well, the answer is unfortunally a NO in the first place.
MI is based on standard JSP and AWT functionality - up to Version 7.0 - and both runtime environments do not support that stuff on PDA.
If you run the APP on Lapop only, you could build something like that with Java Script in HTML or extend the functionality there with some Add ons externally available that can be filled by normal XML. But this is outside the usual MI scope, it depends on your creative level. WebDynpro on the other side supports you with a tree view as I remember, so this could be an option - but again, only on Laptop.
The question is: why do you not split the tree view to several pages? I have no idea about the amount of data you need to carry with you, just in the first place already. Usually tree view could mean a lot of data and this could end up in a long waiting time just to display the first page. Perhaps it is an option to show the actual level of the tree and if the user selects on item, then this item is added to the path (how has he got there) and the next level is displayed in the screen. Pretty much like the Windows Workplace, where every klick on a folder opens a new window with just the info of that window. Performance wise tis could perhaps be the better option.
Does this help?
Regards,
Oliver
