How to get the attribute values out?

Hi everyone,
<root>
<category name="Mens Clothing" id="0">
<subcategory>Active/Baselayer Tops</subcategory>
<subcategory>Active/Baselayer
Bottoms</subcategory>
</category>
<category name="Womens Clothing" id="1">
<subcategory>aaa</subcategory>
<subcategory>bbb</subcategory>
</category>
</root>
How to get the attribute values out? For example "Mens
Clothing" and "Womens Clothing".
// the line below returns "Active/Baselayer Tops" and
"Active/Baselayer Bottoms"
var myXml:XML = new XML(event.result);
Thanks,

Here is attribute identifier operator from FB Help:
@ attribute identifier Operator
Usage myXML.@attributeName
Identifies attributes of an XML or XMLList object. For
example, myXML.@id identifies attributes named id for the myXML XML
object. You can also use the following syntax to access attributes:
myXML.attribute("id"), myXML["@id"], and myXML.@["id"]. The syntax
myXML.@id is recommended. To return an XMLList object of all
attribute names, use @*. To return an attribute with a name that
matches an ActionScript reserved word, use the attribute() method
instead of the @ operator.
Operands attributeName:* — The name of the attribute.
Example
How to use examples
The first example shows how to use the @ (at sign) operator
to identify an attribute of an element:
var myXML:XML =
<item id = "42">
<catalogName>Presta tube</catalogName>
<price>3.99</price>
</item>;
trace(myXML.@id); // 42The next example returns all attribute
names:
var xml:XML =<example id='123' color='blue'/>
var xml2:XMLList = xml.@*;
trace(xml2 is XMLList); // true
trace(xml2.length()); // 2
for (var i:int = 0; i < xml2.length(); i++)
trace(typeof(xml2
)); // xml
trace(xml2.nodeKind()); // attribute
trace(xml2
.name()); // id and color
} The next example returns an attribute with a name that
matches a reserved word in ActionScript. You cannot use the syntax
xml.@class (since class is a reserved word in ActionScript). You
need to use the syntax xml.attribute("class"):
var xml:XML = <example class='123'/>
trace(xml.attribute("class"));

How can i get the random values from database?

i want to get random values from database.
I try my best find no solution
plz give solution in either sql query or java method.
thanks in advance.

Random value out of a HashMap

Hi, I'm trying to make a translation program (for testing purposes)
I've put the words and their explanation in a HashMap like
key value
Run --- loop(wich is the translation in dutch)
I'm not sure if this is the right collection i need for it.
Another way i know is to create 2 arrays and do it that way...
But now I want to show a random key out of that Map or just loop trough them,how can that be done.
Can a moderator replace my message to the java newbies section :p I didn't saw it until now.

I'm in a generous mood
define this interface
import java.util.Map;
public interface RandomMap extends Map {
     Object getRandomValue();
}define this class
import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Random;
import java.util.Set;
public class RandomMapImpl implements RandomMap {
     private Map innerMap;
     public RandomMapImpl() {
          innerMap = new HashMap();
     public Object getRandomValue() {
          List list = new ArrayList(innerMap.values());
          if ( list.isEmpty() ) {
               return null;
          int index = new Random(System.currentTimeMillis()).nextInt(list.size() -1);
          return list.get(index);
     public void clear() {
          innerMap.clear();
     public boolean containsKey(Object key) {
          return innerMap.containsKey(key);
     public boolean containsValue(Object value) {
          return innerMap.containsValue(value);
     public Set entrySet() {
          return innerMap.entrySet();
     public Object get(Object key) {
          return innerMap.get(key);
     public boolean isEmpty() {
          return innerMap.isEmpty();
     public Set keySet() {
          return innerMap.keySet();
     public Object put(Object key, Object value) {
          return innerMap.put(key, value);
     public void putAll(Map t) {
          innerMap.putAll(t);
     public Object remove(Object key) {
          return innerMap.remove(key);
     public int size() {
          return innerMap.size();
     public Collection values() {
          return innerMap.values();
}you could make it simpler still by defining the following class instead
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Random;
public class RandomMapImpl extends HashMap implements RandomMap {
     public Object getRandomValue() {
          List list = new ArrayList(values());
          if ( list.isEmpty() ) {
               return null;
          int index = new Random(System.currentTimeMillis()).nextInt(list.size() -1);
          return list.get(index);
}but I'm not a big fan of class inheritance, it could cause you problems later. up to you

VB Script to accept PC names in text file and get registry key value out of those systems

Hi All,
My task: Create VB script to accept PC names from a text file, process each host name to get Registry key value of individual host name and finally export them to a text file or an excel sheet having registry key value against each pc.
I want to pull key value of LSFORCEHOST located in HKCU/Environment of each PC and export this value against each pc in a text or Excel file.
What I achieved: I am able to process against single pc name but failed to process 3000+ systems listed in a text file which I tried to process through VB script. I am not pro and learning the VBS and cant write complex code.
My VBS code written so far(It failed many time with issue):
Option Explicit
Const HKEY_CURRENT_USER = &H80000001
Dim oFSO, sFile, oFile, sText, strComputer,oReg, strKeyPath, strValueName, strValue, objFSO, objFile, strContents
Set oFSO = CreateObject("Scripting.FileSystemObject")
sFile = "test.txt"
If oFSO.FileExists(sFile) Then
Set oFile = oFSO.OpenTextFile(sFile, 1)
Do While Not oFile.AtEndOfStream
sText = oFile.ReadLine
If Trim(sText) <> "" Then
strComputer = sText
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\default:StdRegProv")
strKeyPath = "Environment"
strValueName = "LSFORCEHOST"
oReg.GetStringValue HKEY_CURRENT_USER,strKeyPath,strValueName,strValue
Const ForReading = 1
Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\destination.txt",1, ForReading)
strContents = strValue
Set objFile = objFSO.OpenTextFile("C:\destination.txt",2, ForWriting)
objFile.Write strContents
objFile.Close
End If
Loop
oFile.Close
End If
I think when I tried to process each PC name from text file against registry key value, above code not working. As per my knowledge some issue in loop. Do I need to add FOR EACH feature?
Please help to correct it. Thanks in advance.

Your code contains numerous errors. Furthermore you make things difficult for yourself by giving similar names to the objects used for your input and output. If you are a systems administrator then your best bet is to make an effort to learn the language
instead of grabbing a few code fragments from here and there and hoping that somehow they will work.
Try the cleaned up code below for this particular project. Note the consistent code indentation. It helps you enormously when trying to understand the structure of the code. Remember also that you must fully qualify all file paths. Writing to "Destination.txt"
will cause endless confusion because you never know for sure where this file will reside.
Const HKEY_CURRENT_USER = &H80000001
Set oFSO = CreateObject("Scripting.FileSystemObject")
sKeyPath = "Environment"
sValueName = "LSFORCEHOST"
sFile = "D:\Test.txt"
If oFSO.FileExists(sFile) Then
Set oInput = oFSO.OpenTextFile(sFile, 1)
Do While Not oInput.AtEndOfStream
sComputer = oInput.ReadLine
If Trim(sComputer) <> "" Then
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" _
& sComputer & "\root\default:StdRegProv")
oReg.GetStringValue HKEY_CURRENT_USER,sKeyPath,sValueName,sValue
Set oOutput = oFSO.OpenTextFile("D:\destination.txt",8, True)
oOutput.WriteLine sValue
oOutput.Close

Excluded Values Appear in BI Query Results

A text file containing 587 material numbers was attached to a query selection screen on the "Exclude single values" tab. The query executed successfully, however, 150+ materials from the exclude file appeared in the results. Investigation into why this happens found:
1. When only 500 materials were imported to the "Exclude single values" tab none of the excluded materials appeared in the results.
2. When more than 500 materials were imported to the "Exclude single values" tab 150+ random materials from the exclude list appeared in the results.
Is there a way to ensure that when more than 500 values appear on the "Exclude single values" tab that none of them appear in the results?

Hello Christopher,
I think SAP Note 1130917 explains the issue you are seeing. Have a look and hopefully this will help.

I dont think you can capture the offset applied value in a exit as the value is dependent on the variable itself and nothing to capture the result after the offset has been applied.
why dont you capture the variable value itself and apply the logic to do an offset in the customer exit?

Getting an int value out of a textfield?!?

Okay so I have just started getting into Java programming and I have stumbled upon a problem. I am trying to make a little program that takes a value from one TextField then another from the next TextField and then puts the sum in the third value. But what I don't know how to do is how do I get the value from the 2 textfields? I know the .getText() method, but that returns a string and I need to get an int so that I can then add the two. Can anyone help me with this?? Thanx!
Fellow programmer

String mynum = myField.getText();
int getint = Integer.parseInt(mynum);
Now the getint has the value of mynum which gets its value from the field.
I think this is what you are wanting good luck

Getting the full value out Jdeveloper when used with Toplink.

Hi guys. Okay, I am going to show my ignorance of Toplink and maybe even Java!
But, I don't understand the toplink mapping process. I have done some tutorials on OTN that have me use the Table-to-Object wizard on Jdeveloper. That worked great.
But now as I use my own real database, the tables have forgein key relationships between multiple tables and such. When I tired the same excercise with these tables, I get a crazy StackOverflowError when I try to run my test app.
I notice that when I create the Objects at the same time, there are collections and links put in between the classes, but when I do them one at a time, I get just POJOs basically.
So what I don't understand is, Am I supposed to bring my objects to Toplink, already created and oriented to each other?
And what are all those links between classes when I use the wizard?

I was looking for the exact version to have the engineers review what might have caused the issue. 10.1.3 developer preview 4 has been thoroughly tested and we have not been able to get a stack overflow exception during the POJO generation from tables.
I would like to get a schema creation script that we could use to reproduce this issue. I can be contacted at douglas.clarke at oracle.com.

Numeric value out of range (null) - Inserting a double

Allright,
I can't figure this out to save my life.. I am refusing to put my code up because I am trying to insert into a DB Table with 140 some fields, so I will explain as best I can.. I am trying to insert a double into my DB.. I have been getting a numeric value out of range error on insertion. Just to see if it was a db problem, I shortened my query to 4 fields and two of them being the doubles for insertion. They inserted fine. So needless to say, i presumed that my insert statement for the 140 fields query was off. I double checked it and everything seems to be in order. I still get the error. I can assure that everything matches up.. my SQL string looks like this :
SQL = "INSERT INTO TABLE 1 (VAL1, VAL2, VAL3 ... VAL146) VALUES (?, ?, ? .... ?);
and my preparedStmt :
ps = con.prepareStatement(SQL);
ps.setInt(1, val1);
ps.setInt(2, val2);
ps.setString(3, val3);
ps.setDouble146, val146);
ps.executeUpdate();
Please help me solve this..

Normalization of query result

Hi BW Geeks.....
I created a report and my requirement was to get the ratio of Employee1 salary to the Total salary. So in the properties of the Salary Key Fig I choose Calculate single value as Normalise to Query Result. It gave me percentage(ratio) of each salary to the total salary. But when I multiply Normalised keyfigure with a restricted kf ,..the ratio doesnt get muliplied instead the actual value gets multiplied.
eg:----
Salary   Normalised to Query result
$5000      5000/8000 = 62.5%
$3000      3000/8000 =37.5%
Total---$8000
Now when I multiply this Normalised Query result with another restricted kf who has value say $1000 I get (5000) X (1000)-= 5000000 which is wrong. I want to get (62.5%)X (1000)= $625.00.
Can ne body please tell me y its doing tht way....Please help me its urgent
I will assign full points
Nikhil

Hi Nikhil,
The display option does not change the underlying value of the key figure, so when you are multiplying the mormalized value it will still use the underlying value in the calculation.
The other option to do this would be:
Create a new calculated key figure "salary" with a percentage function which is Percentage share of overall result. This key figure will display the data in %.
You can then use this calculated key figure in your subsequent calculated key figures.
Let me know if this helps.
Cheers

Query Result Filtered using User Roles SCSM 2012 R2 RU2

Hi,
I have a Query Result setup in a Request Offering that shows the list of Printers using the Printer CI. We have different sites with printers that start with the site location like MTL. There are no filters in the Query Result. What i did is create a Group
for each site that has the rule "start with" MTL (other groups have other 3 letter prefix). Then i created a user role for each group and only selected the Printer group for the site and i associated the User Role with our AD Site group called MTL-User.
i did this for each site. Now when i checked the Request Offering at first, with a user that is part of MTL-User group, it showed only the list of printers that started with MTL. Now today i came to check again and the same user is seeing all the printers
and not just the ones that start with MTL.
The User Role i made was based on the Read-Only Operator. I just dont know what the problem is

Thanks for that link. I had thought of something like that but i found it came to the same thing as just using the filter field that is already available when using a Query Result. I retried using User Roles and figured out that the problem is that my test
user is only part of the MTL-USER group so when i logged in with him into the portal (cireson Portal btw) i would see the proper result. If i logged in with a actual user that is also part of other groups besides MTL-Users, they see all the printers no matter
which AD group i define in the User Role.
So what i figured was that my group is not getting applied as the filter to the query Result and that the Member section in the User role is only to say who can see the Query result list. But then i have my test user for which this setup works...so im confused
on what exactly is overriding the results.

Exporting query result set into CSV file using Forms

Hi ,
My requirement is
-> I need to create a form where I have a Multi line text box and two button.
-> When I enter a query in text box and click on Execute button, It should execute a select query.
-> After execution, Result set needs to be exported into an Excel file.
Please give a hint how to do this????
Thanks,
maddy

as you are using text item to write SQL query by the user
so for that you need to use the exec_sql package to parse the text items query and get definitions and values of the columns being
resulted in the result set of the query.
once your query is execute to the desired connection then you need to use fetch the result to the CSV file by use of the TEXT_io package
which will open the text file with .csv extension and you have to pass the each line to that text file with comma separated values as "ss","rr" etc.
or you can use the ole2 package to call the excel application and then fetch the data of exe_sql query to that.
