Store XML node value into an array with node element name
Hi,
I have the following code that displays the node element with the
corresponding node value. I want to store the values in an array in
reference to the node name.
i.e.
XML (my xml is much bigger than this, 300 elements):
<stock>
<symbol>SUNW</symbol>
<price>17.1</price>
</stock>-----
would store the following:
*data[symbol] = SUNW;*
*data[price] = 17.1;*
Thanks in advance,
Tony

I still need to store it in an array because its 300 elements in the XML stocks.
I've done the following but its not working, i'm getting error codes. I think its an easy fix. I'd also like to pass a String instead of a .xml document b/c my xml is stored inside a DB. Any suggestions on that?

How to insert values into an array of class
Hello everyone,
I need help in inserting values into an array of class, which i have read from a file.
Length of the array is 5. I should insert values one by one into that array.
If the array is full (if count = 5), then I should split the array into 2 arrays

How to create array with "n" elements...
Hy, how can i create a array with "n" elements ?
i know, but the thing is: the other methode (which
one isn't developed fom me) needs an Object Array
(Object []) to work correctly...then take a look into the method toArray() of the Collection interface.
thats why i need this gay "object Array"....I think it would be wise to avoid that adjective in this context and meaning. -
Sort array with equal elements
Hi, I'm a new one.
I have a problem to sort 2d array with equal elements (it has 5000000 of elements from 1-255) for example:
1 2 1 1 3 4 5 5 6 1 2 3 (value from 1-255)
2 2 1 1 3 3 3 3 4 4 4 1 (value from 1-255)
And I need make array or matrix 255 rows vs 255 colomns, and count how many equal elements for example:
1 2 3 4 5 6
1 0 1 0 1 0 0
2 0 1 0 1 0 0
3 1 0 1 0 0 0
4 0 0 1 0 0 0
5 0 0 2 0 0 0
6 0 0 0 1 0 0
I'll be happy if someone could help meI understand that it's very complicated explain.
I build 2d array from two 1darray each of them has values 1-255. So right now i must constract array or matrix 255x255 where must calculat how many times value from (1-255) for one array in another array and write this sum for each value 1-255. I try to show it
1 2 so I need array 3x3; for first row for value 1 I have two times value 3 and one time value 2
2 2 2 I have two times value 1 and one time value 2 and one time value 3
3 2 3 I have two times value 2 and one time value 3
3 2 so my result matrix will be 1 2 3
3 3 1 0 1 2
2 3 2 2 1 1
2 1 3 0 2 3
2 1
1 3

from xml where id=1
There is nothing returned.
Please advise how could I get the node value when there is namespace?
I know how to extract values if there is one namespace but i'm not able to extract values if there are two namespaces.
Any help is appreciable!!
Thanks in Advance.I fixed that problem too. What I thought was a singleton was actually a repeating element. I needed to be able to "multiply" the repeating node for the main node, but I couldn't find a concise way of doing this in SQL. So instead I did it in with two loops.
FOR rec IN (
SELECT
extractvalue(value(e), 'surchargeEntry/company',p_namespace) company
,extractvalue(value(e), 'surchargeEntry/surchargeType',p_namespace) surcharge_type
,extractvalue(value(e), 'surchargeEntry/shortDescription',p_namespace) short_description
,extractvalue(value(e), 'surchargeEntry/longDescription',p_namespace) long_description
,e.column_value surcharge_entry_xml
FROM TABLE(xmlsequence(extract(p_xml, 'surchargeInquiryResponse' ||
'/surchargeAttributes/surchargeEntry'
,p_namespace))) e
) LOOP
FOR rec_country IN (
SELECT
extractvalue(value(c), 'country/originationCountry',p_namespace) origination_country
,extractvalue(value(c), 'country/destinationCountry',p_namespace) destination_country
FROM TABLE(xmlsequence(extract(rec.surcharge_entry_xml, 'surchargeEntry/country',p_namespace))) c
LOOP
nafta_fee_obj.append_surcharge_entry_data(
v_arr
,r_surcharge_entry(
rec.company
,rec.surcharge_type
,rec.short_description
,rec.long_description
,rec_country.origination_country
,rec_country.destination_country
END LOOP;
END LOOP;
I populate a collection, which is easy to pass around between routines. I can easily convert the collection to a ref cursor, and index-by array, comma-delimited string, etc.
Apparently, the namespace is required in SQL, but not in staright PL/SQL.
I've also noticed that the docs say xmltype() has all these member functions, but when I try to use some of them, I get an error that it's undefined. Like getNumVal(). There are some functions I can use in SQL, or PL/SQL, but not vice-versa.

How does this program group and cluster these button values into an array?
In the attached program, there are 6 buttons in a cluster and 1 individual button. These buttons control a bunch of different relays to control power to different components of a single device. Right now the program works in that I can control the 6 buttons, the LED turns on in the board and the power is being transmitted. What I do not understand is how it is doing this. I ran the program with the highlight execution on and at the start of the read from array component, if say I pressed button 6 and hit ok, it reads #6, where did these get defined and labled? and if i wanted to add another button/relay how do i do this? If someone could explain step by step how this is grouping the relays on the board into an array and then controling them I would really appreciate it. Thanks.
Solved!

Cluster to Array.vi 85 KBThe #6 your seeing is the number of elements in the array not a value for the array.
Now for some deeper explainations. From the code it appears that exactly 1 of 6 valves may be used and an additional valve may be in one of two possible states.
When the program is run the cluster of buttons is initiallized to all False. and we enter the outer while loop where a sequence structure starts. In the first frame of the sequence we initiallize a shift register to hold the current value of "Buttons." and this loop runs unthrottled (Add a wait for next ms multiple to this loop to prevent using 100% of the CPU!)
For each iteration the buttons are read and if a change has occured to any value buttons that were previously True are reset to False to prevent opening more than one valve.
When the user presses OK or stop- the current "Buttons" value is passed to the next frame. This frame convertsthe 7 boolean values to a integer where each valve is controlled by a seperate bit of the integer (Isolation is bit 6 and bits 0-5 each control a mixing valve)
Now I'd strongly recommend reworking the DAQmx calls- it is pointless to initiallize the task each time you want to use it- Create the task in the initialzation case and wait until the user exits to destroy the task. And well a sequence structures are frowned on- (there are better ways to do this)
As far as adding a relay- right now the relays are associated to the hardware by their index position in the cluster (element 1 = bit 0 etc....) to add a new valve you would need to decide what bit you would use to drive it and code in that bits' value to write a 0 in that bit. (hint the 40 constant is realy 0x40 right-click>visable items>show radix )
Let me know if you need further elaboration

How to add one value into Input Entry Screen of Element
Hi ,
How to change the "Input Value" of Element which has already been processed and assigned. Its not allowing to update even though its been date tracked.
I want to add one more Value into Input Value screen.
Thanks
RamYou cannot remove existing input values or add new one if you have created any entries for the element

4 Node Q-Master Cluster issue with Nodes stuck at "Waiting"
I have a 4 node QMaster cluster configured no problem, One Cluster Controller and 3 Service nodes. When i export a project from FCP to compressor i can assign the cluster no problem. Then the only node that starts to process is the cluster controller, The service nodes stay at Waiting.... I f i make any other service node the Cluster controller then THAT node starts to process and the 3 Service nodes are stuck at waiting.
I can mount the cluster storage on all nodes and i am able to read/write to that volume.
The source material (Firewire drive) is also mounted on all nodes.
The setup is a new MB-PRO running FCP 5.0 and Compressor 2.0, QMaster 2.0 , the cluster nodes are all 1ghz G4's
Any ideas?
Many thanks
MACBOOK PRO 2.1 Mac OS X (10.4.6) Multiple G4's
MACBOOK PRO 2.1 Mac OS X (10.4.6) Multiple G4'sI don't recommend submitting to a cluster directly from the timeline. Instead, export a QT referance movie, and submit that to the cluster via compressor using a setting that has 'allow job segmenting' checked. If that is not checked, then you are telling Qmaster to only let one machine work on that file - this is recommended for high quality, multi-pass VBR Mpeg2 jobs because of how multi-pass and VBR work...
If you submit from outside FCP, but you are doing multi-pass VBR, you can send your cluster 4 jobs that will all happen at the same time tho.
Basically, to use all the nodes, it needs to have the whole file and be allowed to break it into segments, and send thos segments to the nodes. when you export off the time line, fcp sends the data to compressor frame at a time, not as a whole file, thus, no segmenting. -
Store int values into dynamic array
Hello all,
I'm a newbie in JAVA whose want to store int values (coming from a resultset) into an dynamic array. I know that normally to create a "dynamic array" you'd better use a Vector, but it seems that I don't know how to use it correctly (throws me a exception as : Incompatible type for method. Can't convert int[] to java.lang.Object[]).
Thanks in advance

Hi!
I'm trying to have an analog square wave input determine where data gathered from a second analog input channel is stored. I want data to be stored to one array during the high signal period of the square wave and data to be store to another array during the low signal period of the square wave. The square wave I'm using is of constant frequency (8.3 Hz). I believe I need to use an analog input wave as opposed to a onboard clock or other timing mechanism because my square wave is also being used to modify the input going into my experimental setup. Thus the data storage needs to be correlated to the timing of the data modification in the experiment. I tried to use the retriggerable property node function, but receive error 200452, which I think means that my PXI card (6115) can't support this retriggerable function. So I'm looking for other ways to accomplish alternating data storage in response to an incoming analog square wave. Any help would be GREATLY appreciated... Thanks! (I'm also quite new with LabView so toddler-type explanations would probably be most useful )

Pulsed_Acq_Switch_Simplified.vi 47 KBHello Shari,
I am looking at your situation and it seems very intriguing. after downloading your file I have a couple questions to ask if you don't mind answering.
Currently in your program you are only taking one sample of data at a time, this could lead to uneven sampling. Would you like to sample at a consistent rate (say 10 Kilosamples of data a second?) if so what type of card are you using?
Also, Do you want your data to be in a 2-D array of data?

Create tree and store it's value in an array
I have to create a tree as shown below:
2--->7-->6-->5-->3
---->4
---->8
Here the numbers are the nodes of the tree and --->denotes the connection between them.
2
7 8
6
5 4
3
Another representation
2 is connected to 7and 8, 7 is connected to 6 and 4, 6 is connected to 5 and then 5 to 3.
Currently I am able to display the graph as shown in the first diagram but while storing the value, I am facing a problem.
I have declared a double dimensional array to store the array index.This gives me 2 as a[0][0],7 as[0][1],6 as [0][2],5 as [0][3], 3 as [0][4] and 8 as [0][1] and lower(2nd) 5 as [0][2].
Now since the timestamps are same for 7 and 8 and that for 6 and 5 so I saved them in the same array location.Instead I want 7 as [0][1][0] and 8 as[0][1][1].
I am using recursion to built and I knw I cant add a new [] everytime.
Can any1 of u suggest me how to store my array?
Thanks
The display I am trying to show instead coming proper in this windows so ------- means the connection between parent and children.
Edited by: abheyb on 25 Mar, 2008 5:45 PMHi,
Here you have to use the pure object oriented concept rather than using procedure oriented(like c).
Design a user defined class according to your problem that extends with any Collection. For Example. TableCell
Declare a attribute TableCell tableCell in your class.
Write the method called addCell(TableCell tableCell)
and printTablecell()
In this method you need to follow the recursion concept.
Design as u need...! If you are designing for binary tree, then you need to declare two attribute called tableCell1 and tableCell2

How to copy existing row value into new row with a trigger. Same table

PierreI will call it a very Wrong design.
It is a wrong Table Design. You are duplicating the data in table and not complying with the Database Normalization rules.
How about Verifying if Column A & B are NULL before inserting and inserting another row and avoiding it in Triggers?
If you are bent to achieve this, below code might be helpful. However, I would never go with this approach. If you would care about explaining the reason for going ahead with such a data model, people could suggest better alternative that might conform with Normalization rules.
create or replace trigger trg_test_table
after insert on test_table
for each row
declare
pragma autonomous_transaction;
begin
if :new.col_a is null and :new.col_b is null then
insert into test_table
select 2, systimestamp, col_a, col_b
from test_table
where pk_col = (select max(pk_col) from test_table b where b.pk_col < :new.pk_col);
