Re: XML downloaded...how to upload?

["Carel Teijgeler" <coteijgeler@xxxxxxxxx>]

Hello  Rick,

There have been mentioned a few good approaches. Placing the XML document on 
the IFS is the shortest route. You can look at XML parsers in java, as there 
are tutorials with sample code at 
http://www-105.ibm.com/developerworks/education.nsf/dw/xml-onlinecourse-bytitle?OpenDocument&Count=500/

David mentioned the XML wrappers for RPG (download at IBM's AlphaWorks: 
http://www.alphaworks.ibm.com/tech/xml4rpg). But beware: documentation is 
hardly existant.

You can change the sample RPGDB2XML programme (hope it is the right name). This 
programme uses the uses the DOM interfaces to read an XML document from the IFS 
into a PF. You do not need the trouble with the vector handling in the sample. 
Using DOM the document is first parsed in memory into a tree structure, then a 
combination of parent element - child element is retrieved. As XML can have 
nesting, this process can be handled in a procedure, which can be called 
recursively, when the child element is in fact a parent element to other 
(child) elements.

Mapping the data to the file can be done, as it is shown in the sample 
programme, using embedded SQL. I personally prefer to place the retrieved data 
in an array element and output that to a flat file (one field); the array I 
defined has 32 entries with a length of 32, a length of 1024. Another programme 
can take that file and create the records in your database.

Conversion can bedone using the UniCode tables provided. The sample programme 
works fine without alteration to this part: I opened the XML document in 
Notepad and view the result of the parsing in my flatfile or the sample PF: no 
strange characters.

Regards.
