Re: XMLSAX parser handling for embedded ampersand

Peter,

It is not XML-SAX that fails parsing the xml document due to a bug, but
the creator of the document who made the mistake. The ampersand is a xml
special character that needs to be encoded as "&".

For example (taken from "ILE RPG Reference":

xmlDocument =
'<meeting>+
<attendee name="Jack" company="A&amp;B Electronics"/>+
<attendee company="City&#x2B; Waterworks" name="Jill"/>+
<attendee name="Bill" company="Ace Movers" extra="yes"/>+
</meeting>';

Is parsed and printed as:

Attendee Jack is from company A&B Electronics
Attendee Jill is from company City+ Waterworks

Feel free to refer to w3schools for details:

Regards,

Thomas.

Gesendet von: rpg400-l-bounces@xxxxxxxxxxxx

XMLSAX does not appear to allow you to handle data like
"smith&brown" ( supplied by customer in a large file )
The parser raises a an *XML_EXCEPTION event when the ampersand is

encountered.

Even if you code for *XML_EXCEPTION events to ignore them it appears
that once encountered all subsequent events are returned as

*XML_EXCEPTION.

Some IBM doco says an ampersand should generate *XML_UNKNOWN_REF but
I always get *XML_EXCEPTION
Another IBM doco says a limitation of XMLSAX is that it does not
handle ampersand.

Anybody found this?
