Re: XML-SAX Handler static variables: How to reset?

Hi Marco,

Since this is an RPG question, I'm not replying to Midrange-L, but rather to the RPG list. Please send follow-ups there. Thanks!


There are many approaches to this...

1) Instead of using "loaded" as your user-defined "Communication area" parameter, you could pass a data structure. Put all of the static stuff in that DS, and then you could reset it from anywhere.

-or-

2) Keep the stuff as static fields in a procedure, but add an indicator named "reset" or something like that to your user-defined communications data parameter. When it's on, the procedure could easily reset the data.

-or-

3) Same as #2, but use a global variable instead of using the communications area. This is, imho, not as elegant, but some people really struggle to understand the communications area concept, so this would be an alternative.


Thoughts?

Hello,

thanks to Scott Klement' s examples now I can parse an XML file, but in case of errors the handler "xml_parse" don't reset some static variables (depth, stackname,stackval), so when I back to my program after "XML Open Error" I find the previous value on these variables, until I logout my user session:

xml-sax(e) %handler(XML_Parse: loaded)
%XML(%trim(filePath): 'doc=file');

P xml_parse B
D pi 10i 0
D loaded 10i 0
D event 10i 0 value
D string * value
D stringLen 20i 0 value
D exceptionId 10i 0 value
D value s 65535a based(string)
D ucs2val s 16383c based(string)
D MAX_DEPTH c 32
D depth s 10i 0 inz(0) static
D stackname s 65535a varying inz('')
D dim(MAX_DEPTH)
D static
D stackval s 65535a varying inz('')
D dim(MAX_DEPTH)
D static

Could someone tell me how to reset them each time I enter the program?

Thanks in advance,
