How to use SAXParser to transform using stylesheet

I've got some PL/SQL code that is generating in-memory XML
document based on query run against Oracle database, and then
transforms that XML using XSLT (for later posting over network).
I've been encountering lots of memory errors and wanted to try
using the SAXParser instead. However, the info I've found on
SAXParser never really talks about transforming using stylesheet.
How would I go about transforming a 'subdocument' at a time (I
need the output to exist as one very large properly formatted XML
document, not as a bunch of separate XML docs). Are there
examples of this somewhere?

Hi. What I understand is, you should pass the value of the body first on a variable before doing the MFL transformation action. Use the Assign action to do this.
Then Use the MFL transform on the value inside the given variable, and you can pass it back to body.

How to simulate discrete fourier transform using CMOS on multisim11.0

Please tell me how to simulate discrete fourier transform(DFT) using CMOS implementation in Multisim 11.0..

vlsi,
If I am reading your question correctly, I think this is more of an issue of IC design rather than how to use Multisim (the circuit you describe is likely very complex and would involve many CMOS/transistor components). If you have an existing or partial circuit already ready to start with, the group could better assist with how to implement or use in Multisim for simulation. Although it is possible to model a comlex digital parts with CMOS equivalent logic and gates, most of the more complex digital parts in Multisim are modeled in XSPICE, which allows the behavior to be described by a truth table and timing descriptions and the pins are modeled in SPICE.
However if you want to use a predefined DFT algorithm inline within a circuit simulation, you can likely use with a custom LabVIEW VI, we have several Fourier Transfer algorithms in which you could process a signal coming from a circuit simulation in which the transform and simulation could be run together.
http://zone.ni.com/reference/en-XX/help/371361B-01/lvanlsconcepts/discrete_fourier_transform/
There is an example of how this can be done with an FFT (which is a type of DFT)
https://decibel.ni.com/content/docs/DOC-7438
Another idea is to use our co-simulation technology in Multisim v12 together with the LabVIEW Control Design tools. The LabVIEW Control Design package has several discrete signal processing algorithms built in and you could use them together for very precise mixed signal co-simulation between an electrical simulation and a discrete processing algorithm.

How to do 2:1 transformation using XSLT in ccBPM?

Hi,
We have the following ccBPM defined:
A A B A/C D E F
Start---R1---T1---S2---T2---S3---T3---S1---END
R1: Receives Synch XML message A via plain HTTP adapter and opens S/A bridge.
T1: Transforms A into message B using XSLT
S2: Sends message B to a legacy system to do a lookup and gets response C
T2: Transforms A and C into D.
S3: Sends D to another legacy system synchronously and gets response E.
T3: Transforms E to the final response format F
S1: Sends F to the original requestor and close the S/A bridge.
We had created an XSLT style sheet which takes into
consideration of multi-mapping message structure (e.g.
ns0:Messages/ns0:Message1/A and Messages/Message2/C...)
For some reason, the integration process always fails at
Step T2. The only error message we got is:
<b>
Incorrect XML format after mapping: Message expected instead of Catalog
</b>
We went thru all the monitoring/trace tool and could not find any more info on the issue.
I'd really appreciate it if someone can explain the required steps
for designing and configuring n:1 XSLT transformation step.
Thanks in advance
-Simon

Hi Duke,
I still couldn't get it to work. I compared my xsl file
with yours and they look similar. I was able to turn on the
DefaultTrace. The trace log indicated the mapping call was
successful. But no output was generated. No error message
either. Supposedly XI combines two input xml messsages into
a single message to feed into the XSLT, is there away to
trace out this single input message?
Also do two input messages need to be correlated?
thanks again for your help

How to see if a DSO is used in any transformation

Hi Friends,
I am starting a new dataflow for a new release, lot of DSO's have been created in previous release, I want remove the objects which are not actually used in any reporting. However there a DSO which is used in one look up this i found when i went thru the code. However there are lot of unused DSO which i like to decommission, but am not sure if those DSO have been used in any transformation, and there is no proper documentation available either, hence its becoming challenging to identify each DSO.
I have used table RSAABAP to see if i can get some concrete info, in that table i got CODE-ID, but with that i cannot identify which other DSO or transformation are using this DSO in the look ups.
Can someone please throw some light on how to identify this issue?.
Regards
BN

Hi Kumar,
Just to rephrase my understanding on your issue :
The issue you are facing is , You have many DSO, which you feel that is not required, but you are not sure weather to delete them or not......as some other transformation might be using the Active table of DSO in the Start/End/Expert Routine.....which you have decided to deleted........
Now below are some options
1) Direct way is display dataflow.......which will tell you where is the direct transformation between the source and Target data target. Now here you will miss those data Targets which are reading the DSO active table in routine.
2) For Lookup/Reads in routines :Find out the Active table technical name of DSO ( /BIC/AXXXXXX00)
      GOTO -
      SE11---> Database table = /BIC/AXXXXXX00
      Click on whereused list icon.....then you can select almost everything from available option available and execute... It will give the Program ID where your DSO is used.
Hope this helps...
Thanks
Mayank

How to remove/ignore the element using SAXParser

hello all,
I want to parse the text content in string from the existed xml file. but had problem with the parser. Does anyone have good idea, how to remove or ignore the <link> tag in tag <text>?
IS: the output is only the rest of part text behind <link style="blue" src="www.test.com" />.
Wanted: the whole text in <text> tags. like "Reach more customers by creating targeted micro-sites using test's multi-store retailing functionality."
Given below is my code :
<?xml version="1.0"?>
<test xmlns="http://www.test.com/test">
<title>test title</title>
<text>Reach more customers by creating targeted micro-sites using test's<link style="blue" src="www.test.com" /> multi-store retailing functionality.</text>
</test>java code using SAXParser

i think u can't modify the xml file using SAX
SAX is only for reading XML
for any modifications in xml file u have to use DOM parser....
correct me if i m wrong....

Help: How to Validate XML using SAXParser and return the entire error list

Hi,
I have a problem, I'm trying to validate a xml document against the DTD. Here Im using SAXParser and having the ErrorHandler object passed when setting the error Handler, like parser.setErrorHandler(errorHandlerObj).
I need an output like where the entire XML document is read and all the errors have to be reported with the line number.
like example:
<b>Line 6: <promp>
[Error]:Element type "promp" must be declared.
Line 8: </prompt>
[Fatal Error]:The end-tag for element type "promp" must end with a '>' delimiter.
who can i achieve this.</b>
what happens with the present code is that it throws the first error it encountered and comes out.
how can i solve this problem

You can try to set the following feature to 'true' for your SAXParser:
http://apache.org/xml/features/continue-after-fatal-error
At least Xerces supports this feature.

How to use 'Extract Values' transformation?

Hi,
I am new to EDQ. I have the following requirement - source system sends me partyname+address details. I need to check in the oracle database and if there is a match then send back the ID along with the input details. I am using Lookup check audit process to check if the data is present in the database. If the data is present then I need to send back the ID. To extract the ID I am using 'Extract Values' transformation. I am not able define the Reference Data for this . Can provide a example how to use the same.
Thanks
Prabha

Just use Lookup and Return.
Though it sounds like you really should be using a match process.

How to skip dtd validation when using SaxParser?

Hi all,
I'm using xerces.jar from apache to parse xml documents. I have a problem when the
dtd file is not accesible. I get a HttpUrlConnection exception. I want to skip this action or to ignore this problem and go further. I thought that the following line of code will solve the problem but it doesn't
saxParserFactory.setValidating(false);
Does anyone know how to do it?
Thanks,
Sergiu

hi,
Thanks for the hint, my problem is that I don't want to load the file in memory.
Therefore I use SaxParser.
Both solutions provided in that forum require loading on the whole file in memory
Any other ideas?
Thnaks,
Sergiu

How do I "Init without data transfer' using 7.0 transformations and DTP's?

I have a data-mart situation where I have a standard DSO object that sends deltas up to a standard cube. This data flow is created with 7.0 transformation and a delta type DTP and has been running fine.
I now have a new single activated request loaded to the DSO object but I DO NOT want this request to delta update to the cube. In 3.x, I used to go into the init infopackage, manually delete the initialization pointer, and run a 'Initialize Without Data Transfer' to make this work. Deltas could then continue as before.
I do not see a way to do this using 7.0 transformations and DTP's. I want to reset the init from DSO to cube so this request does not get updated. Does anyone have step by step ideas on how this can be accomplished?
Thanks in advance for any help on this issue.

Hi,
delete the data in the cube by using oprtion selective deletion based on request number.
(if delta request is deleted from cube, with next load last delta records will also come)
in this scenario there is no need to delete initiaizations option.
in BI 7.0, initialization load is not there.
see below documentation on DTP in SAP help.
"On the Extraction tab page, specify the parameters:
a. Choose Extraction Mode.
You can choose Delta or Full mode.
In contrast to a delta transfer with an InfoPackage, an explicit initialization of the delta process is not necessary for the delta transfer with a DTP. When the data transfer process is executed in delta mode for the first time, all existing requests are retrieved from the source and the delta status is initialized. "

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

XML transformation using XSLT and Resin 2.1.11

I have the following problem:
I'm using a servlet to transform the xml files in my web-app to html. The servlet caches the ones transformed results. For each request it checks if there exists a cached result and if the result is based on the most actual xml file version (checking the "lastModified" method of java.io.File that represents the requested file).
This servlet works fine and without any errors.
My web-app also has some other servlets that use the xml transformation to generate a fragment of html code (the menu structure of my "normal" servlets is defined in one xml file for all other files and servlets).
After invoking these servlets (those that use the xml transformation to create their menu) the first described servlet (transformation of requested xml files) is not working "fine" any longer. All it results is the generated header and footer of the page (hard-coded in the XSL file). The complete content is lost.
Any ideas how to solve this problem?
Thanks in advance,
Thof

1. The cache:
The Hashtable is a field of my servlet called XMLTransformerServlet. The cache is not removed or deleted and none of its items is removed or deleted.
As I said: Caching works fine, wonderful, perfectly...
That's definitively not the problem.
2. Thread safety:
I've made all my servlet methods thread safe (just checked this...)
3. About the "anonymous" other servlet type that uses xml transformations:
Some of my servlets use a (thread safe) method to generate a fragment of html code that will show a simple menu structure. Therefore my web-app uses a file called menu.xml - by that way there's only one menu to maintain what makes sure that all my pages get the same menu structure (finally also the xsl file I'm using for "normal" xml transformation imports/includes and interprets this menu.xml).
The (thread safe) method has transforms the menu.xml file using a special xsl file (menu.xsl) and outputs the result to a StringWriter. From this StringWriter I obtain the code-fragment that will be returned by the method.
Before I saw the class StringWriter the first time I've used a temporary file to output the transformation result. Next I red in the file and returned its content.
Finally - this method is working fine and it's always returning the expected data.
4. The problem:
Sorry for repeating this all the time...
What I'm processing:
 - requesting some xml files -> XMLTransformerServlet is invoked and works fine:
   -> doGet checks the resource (if resource doesn't exist HTTP404 will be responded)
   -> doGet checks the caching state for this resource
      a) resource is in cache and no newer version of the File exists -> return cached element
      b) resource is in cache but a newer version exists in the file system -> recache and return newly cached element
      c) resource is not in cache -> cache the resource and return the newly cached element
 - requesting one of the other servlets (those that use xml transformation for menu generation)
   -> servlets invoked work fine
 - requesting a xml file:
   a) current version in cache -> return cached element
   b) no current version in cache -> transform the xml file and cache it
This last transformation of the requested xml file fails.
It is not failing in the sense of "throwing an exception"... it seems to work 100% fine and results a String that could be responded to the browser.
But stupidly it is not working fine...
Maybe (as you wrote) this is a bug (maybe in Resins xml transformation api).
Just thought someone else might have made a similar experience...

Vocal Transformer opens in MainStage. All controls in VT are visible & editable in MS. Don't set it up at the venue. Set it up in one or more patches before you leave your house. You will need up to twelve sliders or knobs plus one or two buttons on your controller to get the most out of it.
