RE: reserved character in XML element value

Thanks everyone for the great info, and the links. My guess , as Scott suggested, is that the provider does not support CDATA.

Thanks for confirming my perceptions.

But lets test it:

RPGLE code ...

clearSrvPgm();
setContent('');
echo('Your solution: &27 ;');
echo('<br>');
echo('My solution: &#39 ;');
echoToClient();
return;

The result:

No Vern,

%27 is the same as &#39

The first is an escaped char the second is an character entity

&27 - same as &#39 - hex and decimal

&apos isn't and HTML entity and should be encoded as&#39

Most browsers does recognize and render&apos but you may experience
problems in javascript

I think this discussion has made a little sense out of something in one
of our products - I had to HTML-encode things like apostrophes -&apos
did not always work - had to use&27, as I recall.

Now I just saw a site that differentiated HTML-encoding vs XML-encoding
- the former has only 4 reserved characters, the latter has 5. The 5th
one is&apos - not part of HTML, therefore, not consistently rendered,

IME.

Nice!!

Hi David,


Firstly, the parser should not parse the content of a CDATA block.

That

doesn't mean it wont though. You are at the mercy of the

implementation and

they are not all standard. Anybody who has had to talk to many SOAP

servers

learns this lesson quickly.

See http://www.w3schools.com/xml/xml_cdata.asp for some details

confirming your belief.

Secondly, when escaping entities yourself there are a few characters

to

watch out for - not just the ampersand (&):

Certain characters are reserved because they form the structure of the

markup language. they are<>'".

To escape them they are replaced by representations:

< goes to&lt;

goes to&gt;

' goes to&apos;
" goes to&quot;

Because the escaped representations begin with an ampersand (&) that

character is now also reserved! So we have to escape it too:

& goes to&amp;

If you want to escape the characters yourself NEVER escape the

ampersand

last because escaping all the others introduces new ampersands into the
markup and you want to leave those ones alone.

Finally, why work this out yourself? Use an open source tool to do

this.

Henrik has built a good one, and you can download mine at
http://sourceforge.net/projects/xmli/files/ They're free and much

used.

Cheers
