Tree Parsing

Hi,
I am having a Treeset with the following structure
key is a string and value is an object
0 linkObj
00 linkObj1
01 linkObja
1 linkObj2
10 linkObj3
11 linkObj4
110 linkObj5
111 linkObj6.
Tree structure is as follows
0 and 1 are parents
0 -> childs 00, 01 ,02 , 03 ....
1 -> childs 10, 11 ,12 ...
11 -> childs 110, 111, 112 and so on
I would request to parse this structure and fetch me the required object based on the node i pass.
Thanks in advance

theParent is the DefaultMutableTreeNode from you want to search.
Use this piece of code recursively:
Enumeration nodes = theParent.depthFirstEnumeration();
for (; nodes.hasMoreElements() ;) {
Object obj = nodes.nextElement();
DefaultMutableTreeNode objNode=(DefaultMutableTreeNode)obj;
Object userObj = objNode.getUserObject();
userObj is the object contained in the Tree node. So you ask it what you want (eventually make a cast to your object).
Bye, Anteo.

XML Tree Parsing problems

I am trying to make a program that will read the tree of an xml file and later store the data in a different format...
At the moment it reads part of the tree. but then a null pointer exception occurs on the line marked (***) in the .java file attached.
It starts at the base element ('servers' in this case) then finds if it has child nodes, if so it stores them, again and again untill it finds text, it will then print the text to screen, and remove the child from the previous node. If a node no longer has any children it is removed from the list and then the next node is found...
The problem being is that is isnt correctly working, as some of the nodes in the pastNodes arraylist are being replaced by one of their child nodes....so when it comes to the point where the list gets shorter and the next node needs to be found it has an incorrect tree list in pastNodes and dies on me.
The reason for doing it like this is so that i can list the values in a tree like format in an array (eventually) such as 'servers.server.ComputerName' has value 'Bobs_PC' etc. as the program that wrote this leaves multiple smae named variables with different types of value...e.g. like 100 'Name' tags but some refer to a drive name and others to services names.
Any ideas?
Cheers for any help.
Here is my code...sorry that its so long :(

          System.out.print("\n* Reading '"+xmlToRead+"'...");

     DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
     Document doc = docBuilder.parse(new File(xmlToRead));
     // normalize text representation
     doc.getDocumentElement ().normalize ();
     NodeList listOfNodes = doc.getElementsByTagName("servers");
     ArrayList pastNodes= new ArrayList();
     pastNodes.add(listOfNodes.item(0));
     while(((Node) pastNodes.get(pastNodes.size()-1)).hasChildNodes()){
          System.out.println("\n------");
          //stores all new nodes with children
          if(((Node) pastNodes.get(pastNodes.size()-1)).getFirstChild().getNodeName() != "#text"){

          //remove child node from parent once read
          if(((Node) pastNodes.get(pastNodes.size()-1)).hasChildNodes()){
               Node newNode = ((Node) pastNodes.get(pastNodes.size()-1)).removeChild(child);
               pastNodes.remove(pastNodes.size()-1);
               System.out.println("Child Removed: "+child.getNodeName());
               pastNodes.add(newNode);
               //deletes a node from list if it does not have any more children.
               if(!((Node) pastNodes.get(pastNodes.size()-1)).hasChildNodes()){
                    System.out.println("Removed Past Node : "+(pastNodes.size()-1)+"/"+((Node) pastNodes.get(pastNodes.size()-1)).getNodeName());
                    pastNodes.remove(pastNodes.size()-1);
     System.out.println(((Node) pastNodes.get(pastNodes.size()-1)).hasChildNodes());
     }catch (SAXParseException err) {
     System.out.println ("** Parsing error" + ", line " + err.getLineNumber () + ", uri " + err.getSystemId ());

     t.printStackTrace ();
          System.out.print("Done\n");
** And a snippet of the output at the console

Here is my code...sorry that its so long :(There is no problem if the code is long. But atleast it should be formatted to help us read it.
Node child = ((Node) pastNodes.get(pastNodes.size()-
1)).getFirstChild();
          //*** NULL POINTER HERE
//System.out.println(child.getNodeName()+"
deName()+" / "+child.getNodeType());I think you get the NullPointerException when you call a method on the child node. The getFirstChild() method could return null if there is no child node. It is always good to check for nulls.

Tagged text from standford parser

Hello all!
I am using the nlp(Natural language processing).
I am using the standford parser.
My target is to get tagged text from standford parser,
Example from here:
http://nlp.stanford.edu:8080/parser/
like :
the screen is samsung is good
output:
the/DT screen/NN is/VBZ samsung/JJ is/VBZ good/JJ
my code is:
   LexicalizedParser lp = new LexicalizedParser("C:\\englishPCFG.ser");
    lp.setOptionFlags(new String[]{"-maxLength", "80", "-retainTmpSubcategories"});
    String sent ="sound on samsung galaxy is the best.";
    Tree parse = (Tree) lp.apply(Arrays.asList(sent));
// parse.pennPrint();
    System.out.println();
    TreebankLanguagePack tlp = new PennTreebankLanguagePack();
    GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
    GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
    Collection tdl = gs.typedDependenciesCollapsed();
    TreeGraphNode sentence = new TreeGraph(parse).root();the api of this is here:
http://tides.umiacs.umd.edu/webtrec/stanfordParser/javadoc/
but I didnt find it.
thanks for helping

I am presuming that your question is that you don't know where to get the info from.
So experiment.
For example use Tree.pennPrint().
And tdl is a collection. So iterate through that collection, get each item and print the properties of each

How to count number of lines inside methods() using the Doclet API

Wrote a custom doclet using the [Doclet API|http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/doclet/index.html ] .
The purpose for the doclet is to load Java source files and create stubs (which are identical Java source files but do not contain any method implementation details).
Instead, the method implementation details need to be replaced with blank lines...
public class MyDoclet {
     private static String TAB = "\t";
     public static boolean start(RootDoc root) {
          ClassDoc[] classes = root.classes();
          // Parse through class or interface
          for (ClassDoc clazz : classes) {
               Type superClass = clazz.superclassType();
               // Print Methods
               MethodDoc[] methods = clazz.methods();
               for (MethodDoc method : methods) {
                    Parameter[] parameters = method.parameters();
                    println();
                    if (!method.isPrivate()) {
                         print(TAB + method.modifiers() + " "
                                                + method.returnType().simpleTypeName() + " " + method.name());
                         print("(");
                         for (int i=0; i < parameters.length; i++) {
                              Parameter parameter = (Parameter) parameters;
                              print(parameter.type().simpleTypeName() + " " + parameter.name());
                              if (i != parameters.length - 1) {
                                   print(", ");
                         print(")");
                         println(" {");
                         println("\n");
                         println(TAB + "}");
          return true;
As one can see, I am just creating the method and placing the opening and closing curly braces (along with a new \n line escape sequence, in between).
Am not really that familiar with the Doclet API...
Question(s):
(1) What is the best way to figure out how many lines of code are inside each method and then use a for loop to insert the exact same number of blank lines inside the methods?
(2) Is there a way to do it using the com.sun.javadoc.SourcePosition.line() method?
Would really appreciate it if someone could help me because this is an important requirement (hence the 10 Duke Stars).
Happy coding to all,
Mike

This is not possible using the Doclet API, because JavaDoc does not store any information regarding implementation detail. Although MethodDoc#position will give you the line where the method is declared, there is no way to determine where the method body starts and ends.
If you need that much information, maybe you would be better of using a tool such as Eclipse's Abstract Syntax Tree parser. AST will provide you with line numbers for each code expression, hence it is relatively easy to compute the first and last line in a method body.

Hi guys,
How to upload a XML file into sap?
is there any function module?
can anybody give me an example program for converting or uploading XML data into sap.

Hi all,
The XML code and XML file given is running fine for me, but when i am using it, my XML file and code, the tables GV_header and GT_item are filling in the perform but outside perform it's empty. Please find the code and XML file , PLease give the answer its urgent, points will be given for sure.

Treating a text file as a database

I would like to create a database in the form of a simple text file and use Java to access/maintain it.
I was thinking at first that JDBC-ODBC would be the way to go but I'm having syntax problems.
Is there a better way to handle this? Or perhaps does someone have a good example they could share with me?

If you already know SQL, writing your own JDBC driver that will create and access XML documents is easy
by John B. O'Donahue
As Java programmers, we have probably all used JDBC drivers. But until I received a project that was shipped without the commercial database it was built around, I had never thought of writing my own JDBC driver.
A major factor in my decision to attempt writing my own driver was that I was creating XML documents from my database tables anyway. It made sense to use the XML documents as my storage medium, and either replace the entire interface with a DOM interface, or write a JDBC driver to interface to the XML. Well, I hate ripping out code that works, and writing a JDBC driver looked like a lot of fun, so the decision was easy.
The main limitation of XML parsers is that they address the mechanics of the document, although the user is generally much more interested in content. The JDBC API, on the other hand, is geared toward handling data. A marriage of the two can give you the best of both worlds, particularly when you consider that a huge percentage of the XML on the Web was generated automatically from a database in the first place.
In this article, we'll be using the moreover.com news feeds as a real-world example of a practical use of XML. This example also shows off the advantages of a SQL-based approach. We really just want to scan for stories that interest the user, in much the same way as we scan newspaper headlines. A SQL query for headlines containing specific topics is a much more natural, content-oriented approach than a tree-parsing model, which is essentially document oriented.

Workin with threads

Hello all!
I am writing a project that works with nlp(natural language parser),I am using the stanford parser.
I create a thread pool that takes sentances and run the parser with them.
when I create one thread its all works fine but when I create more I get errors.
the "test" procedure is findings words that have some connections.
If I do an synchronized its supposed to work like one thread but still I get errors.
My problem is that I have errors on this code:
public synchronized String test(String s,LexicalizedParser lp ){
    if (s.isEmpty()) return "";
    if (s.length()>80) return "";
    System.out.println(s);
    String[] sent = s.split(" ");
Tree parse = (Tree) lp.apply(Arrays.asList(sent));
TreebankLanguagePack tlp = new PennTreebankLanguagePack();
GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
Collection tdl = gs.typedDependenciesCollapsed();
List list = new ArrayList(tdl);
//for (int i=0;i<list.size();i++)
//System.out.println(list.get(1).toString());
//remove scops and numbers like sbj(screen-4,good-6)->screen good
Pattern p = Pattern.compile(".*\$(.*?)\\-\\d+,(.*?)\\-\\d+\$.*");
       if (list.size()>2){
    // Split input with the pattern
        Matcher m = p.matcher(list.get(1).toString());
        //check if the result have more than 1 groups
       if (m.find()&& m.groupCount()>1){
           if (m.groupCount()>1)
               System.out.println(list);
return m.group(1)+m.group(2);
        return "";

How to get nodes from nlp

Hello all!
My mean problem is that I dont know how to extract nodes from GrammaticalStructure.
I am using englishPCFG.ser in java netbeans.
My target is o know the quality of the screen like:
the screen of iphone 4 is great.
I want to extract screen and great.
how can i extract the NN (screen) and VP (great)
the code that I wrote is:
LexicalizedParser lp = new LexicalizedParser("C:\\englishPCFG.ser");
    lp.setOptionFlags(new String[]{"-maxLength", "80", "-retainTmpSubcategories"});
    String sent ="the screen is very good.";
    Tree parse = (Tree) lp.apply(Arrays.asList(sent));
   parse.pennPrint();
    System.out.println();
    TreebankLanguagePack tlp = new PennTreebankLanguagePack();
    GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
    GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
    Collection tdl = gs.typedDependenciesCollapsed();thanks for helping

NLP as Natural language processing, I assume : that bears some explicit acronym resolution, since, as you may have noticed, you have posted on a "general" java programming forum, where many won't know that - I didn't, I just ggogled it :o).
Moreover, you don't make it explicit whether you are using a library; apparently, yes, presumably, JavaNLP, which again would bear some linking and reference... Again, not everyone may have heard of it (I hadn't, until one minute ago!).
Then, maybe you'll have more chance asking such specific questions on a specific forum devoted to your library.
Have you done so, and do you deem the investigations so far lead you to a general Java question rather than to library specifics? Then link or quote or sum up what you have investigated so far ("I dont know how to" and "the code that I wrote is:...", although clear as to what you want, is rather short in terms of describing what you have tried so far).
Eventually, the library I mentioned seems to have rather extensive online Javadocs (I know nothing of the domain): have you read that?
Best regards,
J.

Database Update and Client Pull

HI,
I want to develop a functionality in which whenever a data changes in the database table then i want to refresh the jsp page that displays the information.
Is there any easy way apart from using a client pull with a fixed interval limit? Something like a database trigger could be trapped and that information sent to the server??
Any opinions? A sample working code would be highly appreciated.
Thanks
Anu

Hi John,
1) I like that the new model adds parameterization. It's cleaner than pulling in parameters from pre-set variables. However, the given example didn't actually make much use of it. The only non-constant parameter multiply-used in the example is the "table" variable. Seems like a lot of work for not a lot of gain, at least in this case?
2) I am cautious that this new template/model condenses the paradigm sooo much, that it is no longer clear where XPath is involved vs straight constant tag names. Yes, Adobe's example is overly-expanded but that's common in code meant to be a demonstration.
3) I also am cautious that the example intermingles direct node creation into the XPath search/processing chain. I've learned to be VERY careful with this. It only can work when the changes made do not interfere with the rule processing. In my model, I simply avoid it completely (by not making node-position or node-add/remove/move changes until after tree parsing is complete.) This will always be a safe model.
Bottom line: while I very much appreciate the parameterization and lintability (is that a word? Sure makes sense to me )... I think I would still define each rule separately rather than bring them all together as an inline array in the rule processing call. To me it seems sooo condensed that the XPath meaning can become lost. (Would someone recognize that //para/section-head is actually an XPath statement that could (in another situation) be //para/* or //para/following-siblings::* ... while some of the other strings are exact-match tag names?)
I realize this is all a matter of style... my preference: clarity for the future reader, particularly when the future reader is me a year later who forgot what all those parameters and embedded methods were all about ...
Blessings,
Pete

Dom - OutOfMemoryError:heap space

Hey
I have a text file with the following format:
galia_na skCiKjcpdm02-pdm23p--2o6 2008/10/28-09:14:11:595 80006024 8860002 68100509 2008/10/15 90 487.35 IskAFT046
1.     galia_na User Name
2.     skCiKjcpdm02-pdm23p--2o6 Invoice OBID (unique ID)
3.     2008/10/28-09:14:11:595 CreationDate or TimestampOut of the Invoice
4.     80006024 Invoice Number
5.     8860002 Batch Number
6.     68100509 Supplier Number
7.     2008/10/15 Invoice Date
8.     90 Currency
9.     487.35 New Amount
10.     IskAFT046 Invoice Type
The file is large, and when trying to build an xml file using DOM tree parser, I encounter " Exception in thread "main" java.lang.OutOfMemoryError: Java heap space". (IT'S because DOM is not working properly with big files, The DOM tree consumes large amount of memory)
The Xml format:

I wonder how to process only one "Month" in a time. Write a fragment of the DOM tree into the targer xml file, remove the month which was already updated in the xml file and continue
I have read about xml streaming, (javax.xml.stream package), but the thing is I have accumulative data tags, netAmount and quantity, and modifying xml with STax involves read it in... modify it, and write it out again
<Year ID="2008" netAmount="15883.700" quantity="6">
<Month ID="Oct" netAmount="2247.310" quantity="3" year="2008">
I wonder if there is a parser I can use for this purpose! I am using MyEclipse with jdk version 1.4 (can't upgrade!!!)
Thanks for the help !
Natalie
