Reading from XML file is too slow

I am trying to read some values from XML file, it takes about 1 or 2 minutes to finish reading, my xml file has about 4000 xml elements. Does anyone know this is normal or something wrong? How could make it faster?
Thank you

fine if it helps others... i hope NI will not be angry *fg*
thx for your bug-report, i do not test the sub.vi until now.
exchange the OR with an AND, solves the problem with the endless-loop, but error checking will not work (the loop only stops if no error AND no start-tag is found)
changing the loop termination condition and putting the NOT from the error condition to the no_starttag_flag do both. correctly stops the loop when error occurs OR no further elements found.
i attached the new sub.vi for version 7.0 and 7.1, also but some colors in the logo, for your convinience

Reading from XML File to Oracle

hello,
I am facing an issue.
I have an xml file which i want to read into an Oracle dB.
for ex
<user>
<user1 ident="1" />
<user2 ident="2" />
</user>
I would want to pick those attributes and insert them into the dB. i have been hunting high and low, but not reached anywhere.
The reason, i am using the xml file is, that the user enters values from 3 forms and those values are stored in the xml file. Now, i want to insert these values in the database.
Any help/suggestion are welcomed and appreciated.
Thank You
Sean

Reading from XML file using DOM parser.

Hi,
I have written the following java code to read the XML file and print the values. It reads the XML file. It gets the node NAME and prints it. But it returns null when trying to get the node VALUE. I am unable to figure out why.
Can anyone please help me with this.

Reading from XML file and updating the table ????

Hi
I have package which reads the hier.XML file and does Update inserts into the 5 tables
i have table called MAIN_tbl with the column cur_date.
The package kicks if this cur_date is one day less than the hier.XML file DT.
Currently i m manually checking this date's to make sure the Main_tbl cur_date is n sync with
hier.XML file DT.
for example :- hier.xml file DT is "20091020" then main_table cur_date should be 10/19/2009
in order to kicks of the pakage.
what i m looking to do ??
compare the hier.xml DT with the main_table cur_date,
if cur_date is -1(Preivous day) of hier.xml DT then run hier_pkg(Package)
if not then update main_table cur_date to -1(previous day) of the hier.xml DATE
Then later write the above logic to update the main_table in a procedure, and
then call the package from the procedure.
below are the top few lines of the hier.XML file which is relevant to the one which we are trying to do
<?xml version = '1.0'?>
<HIER_POSTING num ="111" HIER_TYP="CD" DT="20091020" Global="Y">
FYI : The hier.XML file is located in UNIX space.
How do i accomplish this. any idea ????
Thank you so much in advance. For giving a thought on this problem!!!

Any thought on this guys ???
Thanks!!

Trouble with multiline text box reading from xml file

Hi,
I have a text area, set to multiline. For some reason, when my text imported from xml shows up in the box, it starts several lines down into the box. So for example, my Text box is positioned with the top at the midpoint of my stage, but the text starts about 3/4 down the page, about half way down the text box. Can someone please tell me why this is happening and what I can do to fix it?
I noticed that when I put my cursor in the box and move it up and down, the rest of the text 'scrolls' into the frame, but otherwise it's cut off. please help!
Thanks,
Stan

Proxy service reading from XML file..

Hey all - i am a newbie here.
my project need is to access a xml file, retrieve its content by a proxy service and send its contents to client back.
Do i need to use java callout / MFL transformation? If yes, how?
I do not wish to make use of any corresponding business service for this purpose. Is above possible without using a business service? If yes then how?
Please help me out..!!
Thanks and Regards,
Swapnil K.

Hi Swapnil K.
do the following
1. Create an XML file registered as an XQuery resource like below:
<mapping>
<row>
<key>key1</key>
<value>value1</value>
</row>
<row>
<key>key2</key>
<value>value2</value>
</row>
</mapping>
2. create a simple soap proxy based on your wsdl I assume it would have only one operation with in parameter keyParam and one return paramter rerturnValue
3. add a pipeline pair and create an assing action to the variable rerturnValue assigning the follwing value
$mapping/row[key/text()=$keyParam]/value/text()
where $mapping is your eternal xml resource and $keyParam is the input parameter of your wsdl method.
by doing so you can modify your xml mapping without touching your proxy.
4. in the response pipe of your pipeline pair populate the $body with the appropriate wsdl reponse message containing the value of the rerturnValue varaible

Tony

Reading an xml file from a jar file

Short question:
Is it possible to read an xml file from a jar file when the dtd is
placed inside the jar file? I am using jdom (SAXBuilder) and the default
sax parser which comes with it.
Long Question:
I am trying to create an enterprise archive file on Weblogic 6.1. We
have a framework that is similar to the struts framework which uses it's
own configuration files
I could place the dtd files outside the jar ear file and specify the
absolute path in an environment variable in web.xml which is
configurable through the admin console.
But I want to avoid this step and specify a relative path within the jar
file.
I have tried to use a class which implements the entityresolver as well
as try to extend the saxparser and set the entity resolver within this
class explicitly, but I always seem to sun into problems like:
The setEntityresolver method does not get called or there is a
classloader problem. i.e. JDOM complains that it cannot load My custom
parser which is part of the application
Vijay

Please contact the main BEA Support team [email protected]
They will need to check with product support to determine
the interoperatablity of Weblogic Server with these other
products.

Reading an xml file from jar

I have an xml file in a jar file other than the class that needs to read it. Most of teh posts I've seen reccomend using class.getResource to get access to the jar, but since the file is in a different jar this wont work.
I load classes using URLClassLoader and explicitely access the class I need from a specific jar by creating a url thusly....
jar:file:/" + workingDirectory + "/folder/jarfile.jar!/specificfolder/specificfile.class"
Is there a similar thing for reading an xml file for a jar?

Have you tried:
"jar:file:/" + workingDirectory + "/folder/jarfile.jar!/specificfolder/specificfile.xml"

Depends upon the version of Oracle being used. Going from memory, I think it started with 10g that you had to CREATE DIRECTORY and then use that object in references to disk. It could have been 9i as I skipped that version. If you look at the documentation for whatever provided procedure you are calling it will tell you what it expects.
As the code runs on the server the DB resides on, the data file will need to be network accessible from there in order for your code to read the file.

File Adapter and reading all XML files from direcotry

Problem occurs on PI 7.1
I defined sender file adapter. File name mask is: "*.xml" to read all XML messages from directory.
Quality of service is: Exactly One.
Poll Interval: 30
Retry interval: 30
Processing mode: Archive with option "Add Timestamp".
Processing sequence: by name.
I though that with above configuration my File Adapter will be reading folder for all coming XML files. But somehow it is reading XMLs only when I'm activating it in Integration Builder.
Any idea what can cause such strange problem?

Hi Tomasz,
As per my understanding, you need to activate the file adapter for reading the XML files on your directory. Right?
If that is the case, then the issue might be with the Cache.
1. Clear the cache from the Integration Builder.
2. Check in SXI_CACHE whether there are any issues. Click on Delta Cache refresh to find out if there are any cache related issues.
Thanks,

Reading data From XML file and setting into ViewObject to Pouplate ADF UI

Hi,
I have following requirement.
I would like to read data from XML file and populate the data in ViewObject so that the data can be displayed in the ADF UI.
Also when user modifies the data in the ADF UI, it should be modified back into to ViewObject.
Here is an example - XML file contains Book Title and Author. I would like to read Book Title and Author from XML file and set it into ViewObject Attribute and then display Book title and Author in ADF UI page. Also when user modifies Book title and Author, I would like to store it back in View Object.
Please help me with this requirement and let me know if any solution exist in ADF, for populating the ADF UI screen fields with external XML file data.

Reading external xml files from a jar

Hi,
I am trying to read an xml file from a jar (which is not present inside the jar ) .
I am passing the file name as a string (like C:/folder/filename) to the SAXBuilder but it throwing
unknown protocol: c error.
i tried using an url , tried using a relative path but to no use.
Need help in this regard urgently.
TIA,
Regards,
Harsha

Hi,
Actually, my application needs to read two xml files , parse it, perform some operation and write
the result to an output file.
The names of the two xml files i mentioned, are specified in a properties file as absolute paths. (I even tried converting them to URIs)
The xml files are in the same directory as the jar ( i dont know if it should matter as i am giving the absolute path).
The main class reads the names of the files and passes the names as strings to the SAXBuilder.
This is where i am getting an exception.
Going by what you said, is it not possible for a java class to read a fie outside of the jar ? Is there no way to do this ? And right now i am not sure of how to go about this or if there's any work around . Any help would be appreciated.
Kindly reply at the earliest
TIA,
Harsha
