Parsing .xls(excel) file and creating a .xdat(xml) file out of it
Hi All,
need some tips on a task i am trying accomplish for some days now.
I have a excel file, in which I have 10 columns with 40-50 rows of data.
I have a xml structure in mind, in which I want to put all these data from excel file. But till now I haven't understood exactly how I should go about it step by step.
Should I first parse the excel file and save each row (with the column names) in a list, and then read through each row and insert them in the xml format i have planned?
And how do I open a .xdat data and tell my program to insert the data in the sequence of sets I want them to be saved?
I know it's a pretty newbie question ... but will appreciate any help and tips provided. Would help me a lot to learn this new type of task.
Thank you.
with best regards,
Newbie
If you are using JAXB you unmarshall to read the xml. Then you marshall to write.
So what you do is:
1) Unmarshall your xml document. This means you now have your xml as Java objects.
2) Read through the Java objects using loops, etc making any changes to the values. I think here you want to add values, so you can set your values
3) Now in memory you have your new xml thats been updated, so you can marshall it (save it)
I'd recommend a JAXB tutorial. But the basic steps are:
1) Create an xml file and insure its valid
2) Use a free online utility (http://www.hitsw.com/xml_utilites/) to convert the xml into an xml schema (xsd)
3) Use xjc from the jaxb jar and run it over the xml schema (the command i use is xjc myxmlfile.xsd -p com.example
4) Step 3 above creates all the java classes for you to use so then you can unmarshall. Process. Then marshall
This is just a high level. I might have missed something, but the jaxb tutorial is really good and that's how I learned the process.

Can I unzip the .ipa file and edit the application.xml file
I want to modify the below info to also have an additional string value of 2, which somewhere along the line tells something somewhere that the app can run on the ipad. Is there some info in the compiled application that will error out if I modify this document?

</InfoAdditions>
into this
<InfoAdditions>
- <![CDATA[ <key>UIDeviceFamily</key><array><string>1</string><string>2</string></array> ]]>
</InfoAdditions>you can change the file extension to zip, unzip it, find the application.xml file in one of the subdirectories, edit it, rezip the files, change the file extension to ipa and install.

SSIS Compare 2 flat files and create a third flat file
Hey all,
I have two flat files structured as:
Flat File A:
3213,214,14,21421,354,325
Flat File B:
3213,214,14, 55,89, 21421,354,325
I am trying to create an ETL Package that compares Flat File A, to Flat File B, finds an anomaly, in this case
55,89, then outputs the anomalies to Flat File C, separated by commas.
How would I go about doing this? Everything I have looked at shows comparisons between SQL DB's.
Any suggestions?
Thank youHi, I'm looking for a no code solution for my clients. They're happy with drag and drop, but would prefer a no-code solution. Is this possible?
sorry what do you mean by drag and drop? what will client drag and drop? From what interface?
If you can give bigger picture then it would help
In SSIS you've to implement using SSIS tasks only
And in the above case you need to write code in any case be it script task which is in C#,VB .NET or be it execute sql task which is sql.

What is the best, most efficient way to read a .xls File and create a pipe-delimited .csv File?
What is the best and most efficient way to read a .xls File and create a pipe-delimited .csv File?
Thanks in advance for your review and am hopeful for a reply.
ITBobbyP85You should have no trouble doing this in SSIS. Simply add a data flow with connection managers to an existing .xls file (excel connection manager) and a new .csv file (flat file). Add a source to the xls and destination to the csv, and set the destination
csv parameter "delay validation" to true. Use an expression to define the name of the new .csv file.
In the flat file connection manager, set the column delimiter to the pipe character. -

I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration. -
How to set SAXParser at command-line interface to create a large XML file
Hi,
I am trying to create a large XML file (more than 50 MB) by selecting from Oracle database but failed because of "out of memory" error. According to "Oracle XML Developer Guide", we should use SAXParser to parsing a large XML file. But there is no example to show how to set SAXParser at command-line
Following is what I use to get xml files. It works only when the file is small.
java OracleXML getXML -DateFormat -withDTD -rowsetTag PO_HDR -conn
"jdbc:oracle:oci8:@server_name" -user "ID/password" "select * from table_name"
When I set SAXParser at the way below,
java oracle.xml.parser.v2.SAXParser OracleXML getXML -DateFormat -withDTD -rowsetTag PO_HDR -conn
"jdbc:oracle:oci8:@server_name" -user "ID/password" "select * from table_name"
it failed with the error message: "In class oracle.xml.parser.v2.SAXParser: void main(String argv[]) is not defined"
Does anyone know how to solve the problem? I'll be appreciated very much for your help.
Yihere are my ideas.
register the xml schema.
using xmldom, generate the desired xml output and return as xmltype.
then you can use something like this to check.
declare
xmldoc xmltype ;
begin
-- populate xmldoc from you xmldom function
-- validate against XML schema
xmldoc.isSchemaValid(schema_url, root_element);
if xmldoc.isSchemaValid = 1 then
--valid schema
else
--invalid
end if;

XML Publisher does not create a valid XML file when I try to 'generate '
I am working through an Oracle document that walks you through creating an XML Pub report. I am using HCM 8.9, Tools 8.49.15 and it has XML Pub installed and I have the Microsoft plug-in installed
I have created a query and have downloaded an rtf template and now am on a page where you enter your data source and then click ‘Generate’ for the sample data file. I did it and it created ‘PERSONAL_DATA_PAY.XML’ which is created from a PS Query. However if I click on ‘PERSONAL_DATA_PAY.XML’ it generates a blocky text file that is not an XML file and I can’t go any further.
Do you know why it’s not generating a valid XML file when I click on 'generate'?
