How to use certain parts of a string-parsing???

I have a form which pulls some data from a db. For example, it pulls the following about what office I work in:
DS/ISC/GCS/ABC/DEFG
The DS refers to the larger office, ISC referes to the next office down, and so forth. I CANNOT CHANGE THESE VALUES.
What I'd like to do is 'disect' this long string based on where the "/" lie in the string.
I'm basically only interested in the first two offices. In this example DS and ISC. So, when I want to display the parent office, the only string to display is DS and not DS/. Then on another line, I want to display the sub office ISC and not ISC/ . I guess I could parse? But I'm not sure exactly how to do this. If there is another 'easy' way to do this, I'd open to any suggestions.
TIA

How to use ora:parseEscapedXML() Function with String Content

Hello,
I am receiving a ResponseMessage that returns a string, but the content of the string is actually XML. I have tried to use the ora:parseEscapedXML() function to parses the string (see XML Fragment below) to return structured XML data that can be assigned to typed BPEL variables. The documentation is very limited for this (I've looked in the Developer Guide draft that is available at the OraBPEL site).
2 customer records from XML literal fragment copied from string result:
<?xml version="1.0" encoding="ISO-8859-1"?>
<recordset>
<customer>
<CustNum>AROUT</CustNum>
<CustLName>Hardy</CustLName>
<CustFname>Thomas</CustFname>
<CustEmail>[email protected]</CustEmail>
<CustAddress>120 Hanover Sq.</CustAddress>
<CustCity>London</CustCity>
<CustRegion></CustRegion>
<CustPostalCode>WA1 1DP</CustPostalCode>
<CustCountry>UK</CustCountry>
</customer>
<customer>
<CustNum>BSBEV</CustNum>
<CustLName>Ashworth</CustLName>
<CustFname>Victoria</CustFname>
<CustEmail>Victoria.Ashworth@B's.com</CustEmail>
<CustAddress>Fauntleroy Circus</CustAddress>
<CustCity>London</CustCity>
<CustRegion></CustRegion>
<CustPostalCode>EC2 5NT</CustPostalCode>
<CustCountry>UK</CustCountry>
</customer>
The copy rule for assigning CustNum to accountnumber that fails:
<copy>
<from expression="ora:parseEscapedXML(bpws:getVariableData('DataService_OutputVariable','invokeSpecMsgReturn','/recordset/customer/CustNum'))"/>
<to variable="outputVariable" part="payload" query="/client:QueryResult/client:customer/client:accountNumber"/>
</copy>
Any help would be greatly appreciated.

Hello,
I am attempting to provide more information in order to hopefully get some better guidance here.
1) The BPEL process I built receives input from a client that is one of city name or region name or postal code or country name and returns a list of customer records with their AccountNumber, LastName, FirstName, Email, Address, City, Region, PostalCode and Country. The BPEL flow invokes a packaged integration Web Service that retuns the records in a string whose content is XML (see XML fragment below).
2) The string content returned is vaiable based on the input (i.e. city name="London")
Two customer records from XML literal fragment copied from string result:
<?xml version="1.0" encoding="ISO-8859-1"?>
<recordset>
<customer>
<CustNum>AROUT</CustNum>
<CustLName>Hardy</CustLName>
<CustFname>Thomas</CustFname>
<CustEmail>[email protected]</CustEmail>
<CustAddress>120 Hanover Sq.</CustAddress>
<CustCity>London</CustCity>
<CustRegion></CustRegion>
<CustPostalCode>WA1 1DP</CustPostalCode>
<CustCountry>UK</CustCountry>
</customer>
<customer>
<CustNum>BSBEV</CustNum>
<CustLName>Ashworth</CustLName>
<CustFname>Victoria</CustFname>
<CustEmail>Victoria.Ashworth@B's.com</CustEmail>
<CustAddress>Fauntleroy Circus</CustAddress>
<CustCity>London</CustCity>
<CustRegion></CustRegion>
<CustPostalCode>EC2 5NT</CustPostalCode>
<CustCountry>UK</CustCountry>
</customer>
I want to <assign> each record from the packaged integration service result (the string whose content is XML) to a complexType variable defined within the BPEL Process WSDL (see example below).
XML fragment from BPEL WSDL:
<element name="QueryResult" type="client:recordType"/>>
<complexType name="recordType">
<sequence>
<element name="customer" type="client:customerType" maxOccurs="unbounded"/>
</sequence>
</complexType>
<complexType name="customerType">
<sequence>
<element name="accountNumber" type="string"/>
<element name="lastName" type="string"/>
<element name="firstName" type="string"/>
<element name="email" type="string"/>
<element name="address" type="string"/>
<element name="city" type="string"/>
<element name="region" type="string"/>
<element name="postalcode" type="string"/>
<element name="country" type="string"/>
</sequence>
</complexType>

How to use regular expression to find string

hi,
who know how to get all digits from the string "Alerts 4520 ( 227550 ) ( 98 Available )" by regular expression, thanks
br, Andrew

Liu,
You can use RegEx as
d+
Whether you are using CL_ABAP_REGEX class then
report zars.
data: regex   type ref to cl_abap_regex,
      matcher type ref to cl_abap_matcher,
      match   type c length 1.
create object regex exporting pattern = 'd+'
                              ignore_case = ''.
matcher = regex->create_matcher( text = 'Test123tes456' ).
match = matcher->match( ).
write match

MAX(SummaryNum) +1 bad idea, but how to use sequence part composite column

Hi,
My relational mode is as follows
Policy (policynum PK) has 1:M with Summary (policynum FK, SummaryNum part of PK, other columns part of PK)
Basically for each policy users can enter notes with SummaryNum 1, 2, 3, 4.... These numbers are shown to the user for tracking purpose. I need to make sure summary notes for EACH policy start with 1 (cannot really use sequence in the table in the strictest sense) and are incremented by 1. The current Oracle form basically creates the next highest possible value of SummaryNum by adding one to the currently available highest value. In brief, it is like a sequence number for summaries of a particular policy in the summary table.
PRE-INSERT
SELECT MAX(SummaryNum ) + 1
FROM Summary
I am trying to replicate this in ADF BC (using 11g) and know that not using sequencing and adding one to get the next number is a very bad idea due to concurrency challenges (transactional ACID properties). The reasons are as follows.
•     Using MAX(policy_memo_seq_num) + 1 is not scalable,
•     It will lead to duplicates in a multi-user environment, whether ADF BC, Oracle Forms, or any other technology
I also know how to use create a sequence in db, a related trigger, and then set the attribute in EO properties as DBSequence. My challenge is that since SummaryNum is not a primary key, and instead is part of a composite key in my case, how do I make sure that summary notes for EACH policy start with 1 in the Summary Table.
I appears that i cannot really use sequence in the table in the strictest sense as this will mean that for policies the summaryNum will start from the next available sequence number, but what i really want is to have it start by one for all policies.*
I would appreciate any help.
Thanks,

Not sure if there is a better way, but here is one way. Let's say your table was like this:
    SQL> desc versioned_item
     Name         Null?    Type
     ID           NOT NULL NUMBER
     VERSION      NOT NULL NUMBER
     DESCRIPTION           VARCHAR2(20)and lets say your data looked like this:
    SQL> select * from versioned_item order by id, version
            ID    VERSION DESCRIPTION
          1001          1 Item 1001
          1001          2 Item 1001
          1001          3 Item 1001
          1002          1 Item 1002
          1002          2 Item 1002
          1003          1 Item 1003To select only the rows for the max-version-id, you could do this:
    select id, version,description
    from versioned_item
    where (id,version) in (select id,max(version) from versioned_item group by id)
    order by id
            ID    VERSION DESCRIPTION
          1001          3 Item 1001
          1002          2 Item 1002
          1003          1 Item 1003To capture this as a view object, you'd only just need to paste in the WHERE clause above into the Where clause box of the view object. No need to use expert-mode since you're not changing the select list or from clause.

How to use a var as a string

hello, sorry for my question,
but I want to use a var as a string:
I know it is a completely beginners-question, but I didn´t need it until now:
var zahl = Math.floor((Math.random()*99)+1);
sym.$("frame")
          .css(
                              {'background-image':'url("images/zahl.jpg")'
I tried it with {zahl} and [zahl] but it does not work.
Help would be great
Oliver

Thanks a lot,
but sorry, I have no sucsess:

How to use DB toolkit to input string 255 into ACCESS Database

I am converting an existing LV-Application from LV5.1.1 w/SQL toolkit to LV7.1 with DB-Conn. Toolkit. One of the tables in my MS-Access database has a field of TYPE=memo (allows string lengths > 255 characters). I can't seem to find how to insert this field in the DB-table using the "DB Tools Insert Data.VI" without getting an error. I have tried converting the input string to a [U8] array, but that also doesn't work. Just inputing the long string (390-chrs) also gives an error. Reducing the string length to < 255 allows the new record to be input into the table without errors. However, I need to be able to input the longer strings for the application to work.
Does anyone have a solution to this problem.
Thanks,
Jim Cardinal

How to use certain entries from a txt file as metadata?

So during my plugin development I stumbled on a problem.
I have created a txt file for each picture telling me who's in the photos. So the first column in the file shows all the names that appear in the photo.
I want to add those names into LR for each photo. I thought using them as metadata would be a good idea. Then I could let the user enter a name of some person and create a smart collection having all photos with that person in them.
But putting it into practice isn't that easy.
So I started with the classic metadata definition:
metadataFieldsForPhotos = {
id = 'Person',
title = 'Person'
dataType = 'string',
searchable = true,
browsable = true,
Now I don't know how to actually read only the column entries of the txt file and displaying all the names appearing in it. Another problem is that each photo has its own txt file in "nameofphoto.jpg.txt" So LR must know which txt file belongs to a photo.
I know my question isn't very specific but it would be great if someone could help...

Thank you for the reply. Reading the file how I wanted worked fine and I chose to use keywords, as you suggested.
So now I tried to add the keywords to the pictures and I get:
"LrCatalog:withWriteAccessDo: could not execute action 'keywordProvider'. It was blocked by another write access call, and no timeout parameters were provided."
There's my function so far:
function Finder.findPerson(smartCollectionName)
     local catalog = LrApplication.activeCatalog()
     local photos = catalog:getMultipleSelectedOrAllPhotos()
       LrTasks.startAsyncTask( function()
            for i=1,#photos do
                 local photo = photos[i]
                 local photopath = photo:getRawMetadata("path")
                 local photoname = photo:getFormattedMetadata("fileName")
                 local folderpath = string.sub(photopath, 1, string.len(photopath) - string.len(photoname))
                 local metadataPath = folderpath .. "\.metaface\\" .. photoname .. ".txt"
                 local text = LrFileUtils.readFile(metadataPath)
                 local metadataValues = stringSplit(text)
                 for i = 0, #metadataValues do
                      catalog:withWriteAccessDo( "keywordProvider", function()
                           local keywords = catalog:createKeyword(metadataValues[i])
                           photos:addKeyword(keywords)
                      end)
                 end
           end
      end)
end
So what am I doing wrong?

How to use sed on a literal string containing regex meta characters?

I want to delete the lines from a file which match an arbitrary literal string.
The string is contained in a variable, and may itself contain various regex meta characters such as [,],^,$,|, etc
So, my problem is that sed wants to interpret these meta characters itself. For example:
x='abc[xyz$'
sed -i "/$x/d" file
produces a sed error about the unmatched [, and no doubt it wants to interpret the $ too.
(Of course, I could try and change the string $x so that every possible regex meta character was escaped with a \, but that seems immensely cumbersome. Also, can't see a way of using single or double quotes cleverly.)
Sorry if I am being thick about this, but any ideas or alternative methods would be most welcome!

frostschutz wrote:
With sed, you have to escape meta characters indivudually. That's just how it works. Of course you could do the escaping using sed as well, by replacing all meta characters (including \ and /) with \character.
If you want to match strings literally, use a different tool. Or do it in Bash.
while read line
do
[ "$line" != "$x" ] && echo "$line"
done < file
In Perl/PCRE instead of escaping indivudually there is \Q...\E but sed does not understand that, and \Q\E does not solve all problems either, if there is a \E in the $x you have to escape it with \E\\E\Q or something like it.
Thank you for your swift reply. Looks like sed can't be much of a friend in these circumstances!
Probably will have to go with the Bash file handling method.
Oh well ...

How to use Sockets to send/recieve Strings in XML form?

Hello there to everyone reading my Post !
I am entering a total new subject in my learning about Java Programming, where I will need to interact with a server, I was wondering If somebody could help me with a Question I have; here it is:
A server provided me a Socket, (and that is of course an IP address and a Port), And I am supposed to connect to that server using a Java program that connects to servers using a Socket class, then I am supposed to send a String representing a valid XML, and then the server replies me With another String representing a valid XML which I am supposed to store in a String type.
Is this exact write/read operation possible? If so, could someone please give me some code samples to solve this problem?
PD: The server Does this operation only: recieve/send Strings. as its called transactional switch.

Hi ejp, thank you very much for the quickest of replies.
I am wondering If could you please give me a more detailed source code sample, and the reasons are:
Well, first I am a newbie. and secondly, and most importantly, I actually can try to send the String that represents the XML, but then...
I don't have any idea about how to know when my program has finished sending the String. and therefore I wouldn't know where to put the lines of code that start reading the corresponding response String.
Could you please help me out?
PD: I've been using DOM to read XMLs. Does DOM Objects also allow to read/write XMLs using Sockets?
Thanks in advance!

How to use spare part from damaged equipment to a new equipment in SAP

Hello Gurus,
Sometimes we use a spare part from a discarded equipment to make the present equipment functional. How would this be documented in SAP?
Thanks & Regards
Raghuvarun

Hi Raghuvarun,
There will be several methods depending upon the your final objectives of such requirement.
In case you want to just maintain the spare part and the Equipment from which it has been removed, then use Catalog Codes. In the Object part Catalog maintain the Spare part in the Code part and the Equipment number in Item Text.
This method is hassle free.
In case the requirement's like physically identifying the spare-part etc., then the process would be very complex. You need to opt for not only Material Codes but also the Serialization of all these spare parts.
So you need to first consolidate your objectives of the requirement you have asked for. Then post a Query in detail explaining the objectives.
In most of the cases such requirements are satisfied with ideas like the 1st case I proposed, i.e., Catalogs & Codes.
