Dynamically indexing into element arrays in XPath

Hi All,
I have XML with multiple <message> tags wherein each <message> tag contains multiple <itemBumble> tags
like
<confirmationMessage>
<message id="1">
<itemBundle>
</itemBundle>
<itemBundle>
</itemBundle>
</message id ="2">
<message>
<itemBundle>
</itemBundle>
</message>
</confirmationMessage>
My PL/SQL code to process above doc is
message_index := 1;
document_info := selected_nodes (doc_in, '/confirmationMessage/message["message_index"]/itemBundle');
Above code should fetch only all <itemBundle>
nodes in 1st <message> node
but it is fetching all <itemBundle> nodes from all <message> nodes
What i understand is message["message_index"] is not working..
If you use like message["2"] its working fine...
How to index based on variable value..
Anyboby knows ...?
Thanks

Hi,
I forgot to add one statement
selected_nodes () is user-defined function
it is just wrap up on
xslprocessor.selectnodes (
xmldom.makenode (doc_in),
xpath_in
);

How to insert elements into an array after each iteration of a for loop

I am new to labview and working on an application where I am supposed to store an element into an array (without overwriting) after each iteration in a for loop. I have tried using Build Array Function keeping the indicator outside the for loop and played with indexing but didn't work. Please suggest me an idea how to do it.
Thanks
Solved!

Thank you for your suggestion.Here is my actual application attached . In the first image, a difference in time is evaluated and an enum const of insert into array is passed to the shift register where it takes to Insert element into array phase (Second image). I need to enter the time difference into an array after every loop iteration. Please have a look and could you let me know where I am mislead.

PowerShell: Cannot index into a null array

I am trying to put together a script that will upload documents into a document library. Here is what my script looks like currently...
$fileStream = ([System.IO.FileInfo] (Get-Item $file.FullName)).OpenRead()
$FileName = $File.Name
$NewName = [IO.Path]::GetFileNameWithoutExtension($FileName)
$FileNameArray = $NewName.split("_")
$check = $FileNameArray.Length
Write-Host "My Array:" $FileNameArray
Write-Host "Array Length:" $check
#Add file
$folder = $web.getfolder($docLibrary.rootFolder.URL)
write-host "Copying file " $file.Name " to " $folder.ServerRelativeUrl "..."
$spFile = $folder.Files.Add($folder.Url + "/" + $file.Name, [System.IO.Stream]$fileStream, $true)
$spItem = $spFile.Item
#populate columns
$spItem["First Column"] = $FileNameArray[0].ToString()
$spItem["Second Column"] = $FileNameArray[1].ToString()
$spItem.Update()
$fileStream.Close();
Currently when my script tries to update the columns with the elements from the array, I am getting this error message
Cannot index into a null array.
At C:\powershellscripts\Upload-FilesIntoSharePoint.ps1:164 char:6
+ $spItem["First Column"] = $FileNameArray[0].ToString()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : NullArray
...earlier in the script, I placed checks to see what my array is like, and it hold data. When I ran it, I had 2 elements in my array, those values where printed to the console. However, the script stalls when am trying to get the values into the respective
columns. Does anyone have an idea why this is happening? Thanks.

Hi,
first of all ensure that NewName has at least one underscore and then debug the code to see the value of $FileNameArray[0].

How to put data into a array element in the BPEL

Hi,
I have a element in the WSDL which is of type Array. (i.e accepts unlimited data for the same element). How should i put a data into a array in the BPEL.
Example:
The below Example gives u an idea about wht iam asking:pasting a piece of my requirement:
<s:element minOccurs="0" maxOccurs="1" name="parameters" type="tns:ArrayOfCSParameters" />
<s:complexType name="ArrayOfCSParameters">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded"
name="CSParameters" nillable="true" type="tns:CSParameters" />
</s:sequence>
</s:complexType>
<s:complexType name="CSParameters">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="RevenueItem" type="tns:RevenueItem" />
<s:element minOccurs="0" maxOccurs="1" name="AccountURIs" type="tns:ArrayOfString" />
<s:element minOccurs="0" maxOccurs="1" name="GroupURIs" type="tns:ArrayOfString" />
<s:element minOccurs="1" maxOccurs="1" name="Percentage" nillable="true" type="s:decimal" />
</s:sequence>
<s:attribute name="Version" type="s:decimal" use="required" />
<s:attribute name="URI" type="s:string" />
</s:complexType>
Any suggestion is appreciated.
Regards
pavan

You have 2 options i guess.
Use the transformation and the for-each to construct the array-list
or like Richard said, use a loop in bpel, assign in the loop an variable of element type="CSParameters" and append this variable to your variable with accepts the arraylist.

Oracle sql query - bulk collect into a 50 element array, to print them.

INSERT INTO temp_mobile_donors_au
select distinct d.donor_id
from [email protected] d,
blood_drives b,
ds_malaria_travel_history h
where b.site_code = 'NA19'
and d.coll_date between trunc(add_months(sysdate,-24))
and trunc(sysdate)
and d.drive_id = 'DRV'||b.drive_id
and h.donor_id = d.donor_id;
I have 105 donors. I am taking these donors and have to print a report. I was using loop to print the donor sheet for each donor. Usually we have about 20 to 30 donors. So reports prints without any problem. Now we have about 105 donors and may be next time we may have more. So report does not print for all donors.
I print reports using this command
Cursor C2 is
select distinct donor_id
from temp_mobile_donors_au;
Begin
Open C2;
Loop
Fetch C2 into :param_donor_id;
Exit when C2%notfound;
print_mobile_donor_sheets_au;
End loop;
Close C2;
End;
procedure for print_mobile_donor_sheet_au----- is as below
v_url_c := 'http://'||v_rep_server_c||'report=r_ds_travel_history1&param_donor_id='||:control.param_donor_id;
Is there a way to iterate through a single cursor 50 rows at a time, bulk collect into a 50 element array, print them, bulk collect the next batch.
Any idea or help?

Here is a bulk-collect-limit example that got by googling:
SET SERVEROUTPUT ON
DECLARE
TYPE t_bulk_collect_test_tab IS TABLE OF bulk_collect_test%ROWTYPE;
l_tab    t_bulk_collect_test_tab;
CURSOR c_data IS
    SELECT *
    FROM   bulk_collect_test;
BEGIN
OPEN c_data;
LOOP
    FETCH c_data
    BULK COLLECT INTO l_tab LIMIT 10000; /*I think this is what you are looking for*/
    -- Process contents of collection here.
    DBMS_OUTPUT.put_line(l_tab.count || ‘ rows’);
    EXIT WHEN c_data%NOTFOUND;
END LOOP
CLOSE c_data;
END;
/So you need to three things:
1. TYPE t_bulk_collect_test_tab IS TABLE OF bulk_collect_test%ROWTYPE;
2. l_tab    t_bulk_collect_test_tab;
3. FETCH c_data
         BULK COLLECT INTO l_tab LIMIT 10000; /* use your reqd value */Change your code and try.

What is the easiest way to always increment to index 0 only for a multi-element array ?

The premise is to populate a spreadsheet from left to right in the same row but incrementing the column letter only (ie - B4, then C4 etc). Attached I have customized an existing example VI that works for a 2 element array (ie - B4) but does not work for a 3 element array (ie - B40, then becomes B50). Keeping it simple, what is the best and easiest way to modify my existing code to always check the array size and automatically index back to 0 in order to properly increment the first letter only (ie - B) and not the number (ie - 4) ?
Thanks !
Barry

In case you ever have more than 26 columns (as Ravens Fan noted), here
is some code I use to generate the column label from the column number
(0=A,1=B,...).

Hihow to insert 2 elements into 2D array?

Hi I had a hard time figuring out how to insert 2 elements into 2D arrays.
I tried using replace and insert array functions but it does not work right way.
I am using LV7.1. See the pic below.
How do I insert elements in that way?
Pls advise
Clement

Well, "replace array subset" is not the right tool, because it keeps the size of the array constant. Insert into array only works for entire rows or columns.
You need a hybrid approach, because you want to insert elements at the beginning of column 1 while padding the remaining columns to the new lenght of column 1. This won't be efficient but there are plenty of ways to do that (here is one example with DBL arrays, should work equally well for string arrays as in your case).
How much flexibility do you need? Is it always at the beginning of the first column? Are the arrays huge (=is performance an issue)? Is this a rare operations or do you constantly need to do this (e.g. inside a loop).
In any case this seems like a rather arbitrary and somewhat silly operation. What is the practical purpose?

Now my problem is, that I need for every ROW of my table UI Element a different cell editor. I know how to change it for the column. But is not my issue. I want to have images (traffic lights red and green) in some rows. The other rows should have numbers. The coding works, so that I have all the data at the right place in my table, only the images are shown as a string, because the cells of these rows have the cell editor Text_View. I tried something with cell variants (with cl_wd_table_standard_cell), but it was not possible for me to get a cell variant "image" in these cells/rows were I need it.
I hope you understand my problem and now what to do here.
Thanks a lot in advance.
Best Regards,

I definied my table in Layout Tab of the View and create here in thos method dynamicly my columns. lv_table_column = cl_wd_table_column=>new_table_column( ). . . lv_table->add_column( lv_table_column ). In I have my data that should be shown later in my table. So I create for each row in this fieldsymbol in a loop: lv_element = lv_node->create_element( ). lv_node->bind_element( new_item = lv_element set_initial_elements = abap_false ). Later I fill every cell in my table with a different value with this loop: LOOP AT ASSIGNING . IF sy-tabix EQ lv_cur_row. CLEAR ls_comp_tab. READ TABLE lt_comp_tab INDEX lv_col_count_read INTO ls_comp_tab. ASSIGN COMPONENT ls_comp_tab-name OF STRUCTURE TO . lv_value = . CONDENSE lv_index. CONCATENATE 'A' lv_index INTO attr_name. lv_element->set_attribute( name = attr_name value = lv_value ). ENDIF. ENDLOOP. Now my problem is, that I need for every ROW of my table UI Element a different cell editor. I know how to change it for the column. But is not my issue. I want to have images (traffic lights red and green) in some rows. The other rows should have numbers. The coding works, so that I have all the data at the right place in my table, only the images are shown as a string, because the cells of these rows have the cell editor Text_View. I tried something with cell variants (with cl_wd_table_standard_cell), but it was not possible for me to get a cell variant "image" in these cells/rows were I need it. I hope you understand my problem and now what to do here. Thanks a lot in advance. Best Regards, Ingmar

How do I insert into an array only if the condition is true?

I am buiding an array made up of pairs of data from a file. I am going through line by line putting the values in an array and then taking the pairs of two indexes oring them and putting the number into another array. I do not know if there is more than one set on each line so I have to do a while loop to check.The problem is I have to get the indexes in pairs, so for example I take in the element from index 0 and 1 and or them index 2 and 3 and or them, I do not need the combination of 1 and 2 or 3 and 4 and etc. I am using the "Quotient & Remainder" to check if the index is even or odd, if it is even I take that element and the very next index's element, I or them and put them in another array, but if i
t is odd I do not want to put anything into the array. How can I go about doing that? Any help would be appreciated. I am using version 6.1 Thanks, Molly

Molly,
Rather than running while loop which only executes code every other time you could instead just do a little more math to get your index values. Just multiply the iterator (i) terminal by 2 for the first index and then add 1 to it for the second (you'd need to run the loop half as many times of course). This would be more efficient and easier to read in your code. One other tip is that when you are running a loop a specified number of times it's cleaner to use a for loop rather than a while loop.

How to put 58 columns of data into an array in one shot?

I have a set of data with 58 columns and 5000 rows. However, I need to find offset for all the elements in this 5000x58 set of data. Is there an easier way to put all the data (offset) into an array in one shot other than using build array function? This is because if I use the build array function, I will need to separate all the data into 58 columns by indexing them. This is too time consuming.
Thanks for the suggestion! Have a good day!

You need to explain in much more detail, because your problem is not clear.
Is this a 2D array with 58 columns and 5000 rows?
What is your definition of "offset"?
Where does the offset value come from?
Is "offset" it the same for each row (or column) or does it depend on the data?
What is the definition of "one shot"?
Why would you need to seperate all the data into columns in order to use build array?
It it "too time consuming" to write the program or is the execution slower than expected?
Is the final output a 1D or 2D array or something else?
Please attach a VI containing a small 2D array diagram constant with typical data, then show us what kind of output you would expect after applying the described operation.

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!

The #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

Passing Dynamic Number of Elements and Attributes in Orchestrator

i am having trouble determining the best way, from a powershell snippet in a Run .Net Activity, to pass a dynamic list of elements with each element having a dynamic list of attributes . Example:
on one call of the activity the data might be the following:
element1 with 3 attributes
element2 with 2 attributes
element3 with 0 attributes
on another call of the activity the data be the following:
element1 with 0 attributes
element2 with 3 attributes
i understand how to create objects, arrays, and hashes. i would like to know the best way to pass the data above from the .Net activity powershell snippet (where the data is created) to another activity. Ideally I would like to pass
a custom object created with powershell (not an array or hash), but research tells me that it is not possible to publish an object on the Orchestrator databus. Any assistance is appreciated.

You can try combining the parameters into a single string in PowerShell separated by a delimiter like a semi-colon. Then you can have a single parameter in the Invoke Runbook activity. Once the parameter is passed you can then use the Split Field activity
that is included in the Data Manipulation IP.

You could do something similar for the SQL Query. Just combine the string to a single output in PowerShell and use the PARSENAME function, or something similar, to separate out your parameters.
