Re: XML parsing in RPG.

Hi Rick,

I don't know what the code looks like, but... given your symptom of "...losing all the characters before and including that string...", I'm guessing that the original guy did something like this:

ParsedData = Value;

Instead of:

ParsedData += Value;

i.e. he's wiping out any existing data in the string rather than adding it on to the end.

Scott, well, the guy who wrote it (not available) appears to be attempting
to handle those events, but not correctly I guess.

I suppose I need to crack the books.

Sounds to me like you are handling the XML_CHARS event, but not handling
the XML_UCS2_REF, XML_PREDEF_REF or XML_UNKNOWN_REF events.

If you were handling those events properly, the parser wouldn't "freak"
(which I doubt it's doing, anyway) and you wouldn't have to do any
special "manipulating" of the data.

Remember, refs like &amp; are a normal part of XML. They shouldn't
require any special processing on your part!

hey all,

I'm working on a program to parse XML using the "new" XML-SAX handlers

and

have a question.

I did not write the program, so I'm kind of working backwards here - I
don't fully understand the XML operations - trying to learn as I go, but
I'm sure others must have run across this problem and can give me an idea
of where to look to fix it.

the program works just fine 99.9% of the time, but one of the data

elements

comes through with replacement characters for an ampersand '&' - i.e.

&amp;

the parser sees this and freaks, losing all the characters before and
including that string, making the value whatever is after the ampersand.
basically, it interprets this:

the value is supposed to be: 'TRAVELERS CASUALTY & SURETY CO. OF

AMERICA'

which comes in from the 3rd party (after ebcdic translation) as:
<value xsi:type="soapenc:string">TRAVELERS CASUALTY &amp; SURETY CO. OF
AMERICA</value>
when the parser is done with it, it looks like this:
' SURETY CO. OF AMERICA'

I can manipulate the characters any way I want, but is '&' the only
character that gets treated this way? are there other &xxxx; replacement
variables for other characters?

I feel like I'm fishing without a worm here. I don't want to read every
XML link on infocenter or elsewhere searching for something that should

be

simple.

thanks in advance!

Rick
