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.
Thanks and Regards,

because what you want is not the node value of CODE but the node value of the text nodes into it!
assuming only one text node into it, try this:

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

Hi,
I have been able to read the xml file and convert them into textboxes. The problem, i am facing is, how to i relate each of those values which are generated in the form of textboxes into values required by the Stored Procedure.
has anyone come across this problem or is there a better approach.
please advice
thank you all

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

How to display data in combo box from xml file.

Hi All,
        I have the data in xml file.
<jukebox>
    <song>
        <title>When the Levee Breaks</title>
        <artist>Kansas Joe and Memphis Minnie</artist>
        <url>delhi601(www.songs.pk).mp3</url>

    <song>
        <title>Walk Right In</title>
        <artist>Cannon's Jug Stompers</artist>
        <url>delhi601(www.songs.pk).mp3</url>
    </song>
</jukebox>
and i want to display the only url in combo box list. for that how can load this xml file and how can i show.
Can any one help me.
thanks
Raghu.

Raghuvasa,
Get the XML file data into an XML variable in your code, say var jukebox: xml. Then do
combo.dataProvider = jukebox.song.url
or as a shortcut
combo.dataProvider = jukebox.descendants("url")
The latter will pull out elements with tag name url at any depth in the xml structure, so sometimes you have to be careful, but in your case there should be no problem.

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

Error when loading data from xml file

Read data from xml files and populate internal table

Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...

<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
             xmldata type xstring .
DATA: mr      TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
    WRITE: / struct_accontextdir-context_id,
           struct_accontextdir-context_name,
           struct_accontextdir-context_type.
    NEW-LINE.
    ENDLOOP.</pre>
<br/>
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
    Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
      CALL TRANSFORMATION id
        SOURCE shiv = t_internal_tab
        RESULT XML xml.
    CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
<br/>
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

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.

How to ignore a node while reading data from XML file

Hi All,
I have a XML file that i am reading that XML file using XMLStreamReader and then i need to create another XML file that has specific nodes(from the database).
I need to ignore nodes(with values) that are not in the database and while creating the XML file, only nodes that are it the database should be written in the new file.*
For eg.
<XML>
<Stud>
<Name>XYZ</Name>
<Roll>1</Roll>
<Class>1</Class>
</Stud>
<Stud>
<Name>ABC</Name>
<Roll>2</Roll>
<Class>1</Class>
</Stud>
</XML>
In database i have only two node :<Name> and <Roll>.
So, my new XML will be
<XML>
<Stud>
<Name>XYZ</Name>
<Roll>1</Roll>
</Stud>
<Stud>
<Name>ABC</Name>
<Roll>2</Roll>
</Stud>
</XML>

Hi gborges,
Since you're new to LabVIEW, I thought I would post a few helpful links. A great way to learn some LabVIEW basics is to look over the introductions --
