Re: XML Toolkit - create an XML file to be passed as a parameter

In IBM's modernization redbook there are several different examples to
write XML.

Here is one example from the redbook:

http://powerext.com/jonxml.txt

One thing the CGIDEV2 approach dosn't do is automatical encode special
characters
in the XML data strings so if you have to pass "descriptive" data you may
end up with
invalid XML.

Another thing is that CGIDEV2 typical uses external IFS templates instead
of inline
procedures that powerEXT uses so to chose one or the other is also a matter
of
programming style where the latter method IMO is better for generating
complex XML.

Both powerEXT Core and CGIDEV2 generates XML in a buffer and since they
both are
service programs you can get the buffer address and size generated in one
program from
another program by just including the service program in both programs.

Both powerEXT and CGIDEV2 can either send the XML to a HTTP client or save
it to
the IFS but powerEXT has also a lot of other related procedures so it is
able to
read and manipulate the generated XML or JSON for that matter.

Hi - I found that CGIDEV2 makes writing XML amazingly easy. Here are some
articles that should show you how easy it is.

http://www.scottklement.com/presentations/XML%20From%

You can also go to the home of CGIDEV2 = http://www.easy400.net = search
on that page for "tuohy"- that's Paul Tuohy, who has several articles on
CGIDEV2. They don't mention XML directly, but they have general suggestions
for using CGIDEV2 that I've found helpful. Things like make the tag markers
for sections and variables - make them into comments.

We have CGIDEV2 available as someone contracting for us needed it for
some web service functions. I am not familiar with it as I have been
developing XML apps using the toolkit. Looks like I will be getting
familiar with it now. Thanks for the advice all.

XML Toolkit is not related to CGIDEV2 at all - the latter uses CGI APIs
to write to whatever, including a buffer in memory (a variable).

The toolkit uses some well-known (I think) APIs from the industry -
www.xml.com would be a place that might have some information - it's
hard to get the toolkit's docs, since you get them only when you install
it.

I like moving to CGIDEV2, as well - but it might not be an option, so an
alternative could also be writing out to a user space - that can be
processed just like any IFS file, and you can have a pointer to it that
a variable is based on. Ba-da-bing,

Haven't used those api's and hard to tell without seeing your code.
But it looks like it is based on CGIDEV2 so instead of writing the html to
stream file you can use this procedure, notes form prototype copy member.

******************************************************************
* GetHtmlBufferP subprocedure - Retrieves the pointer to the Html
output buffer
* Returns a data structure containing
* - the pointer to the Html output buffer
* - the used length of the Html output buffer
* Example:
* D OutBuffer s 32767 based(OutbufferP)
* D OutBufferInfo ds
* D OutBufferP *
* D OutBufferLen 10u 0
* C eval OutBufferInfo=callp(GetHtmlBufferP)
******************************************************************
D GetHtmlBufferP pr 20

The other option, you can have it write to IFS file and then read that
file into a variable that you can pass to the other program.

Not sure how to get properly formatted XML document into character
string using DOM api's from toolkit

Can't you just pass it as a large character parm between the two
