How to load XML file to DB

Question

Hi All,
My requirement is I have a XML file, its data should be stored in Database.
Below is the sample XML file.
<?xml version="1.0"?>
<PaymentInfoMessageResponse>
<PaymentInfoResponse>
<TransactionType>940</TransactionType>
<SequenceNum>04</SequenceNum>
<CompanyCode>902</CompanyCode>
</PaymentInfoResponse>
<StatusCode>OK</StatusCode>
<StatusDetail>OK</StatusDetail>
<ResponseItemCount>2</ResponseItemCount>
</PaymentInfoMessageResponse>
I have a table with columns name say TransType,SeqNum
the value 940,04 from XML file should be saved in TransType,SeqNum Column respectively
I am using file adapter with native format builder,selecting file type as complex type and
In design schema,I'm not able to proceed,i'm getting error in POP up as:
Native Format builder:error
No global elements exist.
How can i proceed or any other way to load XML file to DB.
urgent Help/suggestion is required.
Thanks in advance

Answer 1

HI all,
1)If my input is .txt file.
we can use file adapter,using native builder,sample it,
delimited/fixed length, we can do normal file read and file write/DB write.It works fine.
2)If my input file is xml file,we can't use native builder format(Because it doesn't support
delimited/fixed length/complex character in native format builder).
so,as said in the above reply,i took a sample XML file & converted to XSD using
File Menu > New > All Technologies tab > General > XML > XML Schema from XML Document.
It compiles fine.
Now,if i use file adapter(read) -- BPEL -- File adapter(write).
Inside Transform,i am mapping filereadVariable and filewrite Variable correctly.
If my input file is Abc.xml and its contents in read file are:
<?xml version="1.0"?>
<PaymentInfoMessageResponse>
<PaymentInfoResponse>
<TransactionType>940</TransactionType>
<SequenceNum>04</SequenceNum>
<CompanyCode>902</CompanyCode>
</PaymentInfoResponse>
<StatusCode>OK</StatusCode>
<StatusDetail>OK</StatusDetail>
</PaymentInfoMessageResponse>
In write folder,my contents are
<PaymentInfoMessageResponse>
<imp1:PaymentInfoResponse>
<imp1:TransactionType/>
<imp1:SequenceNum/>
<imp1:ReceiptTime/>
<imp1:CompanyCode/>
</imp1:PaymentInfoResponse>
<imp1:StatusCode/>
<imp1:StatusDetail/>
</PaymentInfoMessageResponse>
Now,if i use file adapter(read) -- BPEL -- DB adapter(merge).
Inside Transform,i am mapping filereadVariable and DBmerge Variable correctly.
If my input file is Abc.xml and its contents in read file are:
<?xml version="1.0"?>
<PaymentInfoMessageResponse>
<PaymentInfoResponse>
<TransactionType>940</TransactionType>
<SequenceNum>04</SequenceNum>
<CompanyCode>902</CompanyCode>
</PaymentInfoResponse>
<StatusCode>OK</StatusCode>
<StatusDetail>OK</StatusDetail>
</PaymentInfoMessageResponse>
My output in em console is like this.
<CeStatementHeadersIntCollection>
<top:CeStatementHeadersInt>
<top:statementNumber/>
<top:bankName/>
</top:CeStatementHeadersInt>
</CeStatementHeadersIntCollection>
NO data is being inserted into DB.
I can write my XMl file into write folder as it is using opaque object(No native format translation)
I can write XML file into DB using BLOB data type.
But my requirement is:
I have a table with columns name say TransType,SeqNum
the value 940,04 from above XML file should be saved in TransType,SeqNum Columns respectively.
Can i do it using DOM parser/SAX parser?
So any suggestion/help required
Thanks in advance
