Process HTML Tags Causing Problems

We have a system where emails are sent out embedded with data pulled from
4D...

The system has been in place for a few years, and worked flawlessly until
switching over from 2004 running on a PowerPC to v11.9 running on a MacMini.
In most cases, it still works flawlessly, except for one email in which a
url link is created for the mail recipient to click on.

When the code generates the html, this is an example of the code that is
generated (IP address removed):

http://xxx.xxx.x.x:8181/4DCGI/CGI4D_FileServe&CGI4D_t_actionToTake=CGI4D_R
equest_Confirmation&CGI4D_t_Filename=Confirm.html&CGI4D_t_sessionID=TIDul48X
28601u4a991r

However, after HTML Process Tags, this is what ends up in the email:

HTTP://xxx.xxx.x.x:8181/4DCGI/CGI4D_FileServe&CGI4D_t_actionToTake=CGI4D
_Request_Confirmation&CGI4D_t_Filename=Confirm.html&CGI4D_t_sessionI
D=TIDul48X28601u4a991r

Note that after processing, "and," and been added everywhere after "&",
which means that the link will fail to load the correct web page and data
when the user tried to access it.

I have control over the receiving server, and can strip out the "and,", but
I would like to know why this might be happening in the first place.

Anyone have any thoughts or suggestions?

Re: Send more than 32K in an e-mail body - v11

Sounds like it's 32K *after* encoding.
I use blat with LEP for mailing after various collisions with 4D internet
commands; with the mac you have sendmail, no?

4D and HL7

Hi,

I currently have a stored procedure on the server (4Dv11) that's sending out
HL7 messages generated from 4D.  Acknowledgements are also received within
the same process.  

If there is a need to expand the scope to process an order message (ORM) in
4D, can I set up a different stored procedure to listen to these messages on
a different port? Or do I have to modify the stored procedure to parse
between acknowledgement and ORM messages?

I would also like to seek advice on how to read in and process incoming ORU
HL7 messages coming in from a different machine, eg., an echo machine.
I was thinking along the lines of setting up a stored procedure to listen to
incoming ORMs on a different port, parse the message for its parameters,
then store the data in some date for processing a later instance.

Can anyone advise on the above?  Thanks.

Regards,
Ronnie Teo

Re: 4D and HL7

Hi, further to my last mail, I would to ask if there is any component or
pre-processor that I can use in conjunction with 4D to help in parsing the
incoming ORU messages?  If it is something that we would have to code in 4D
itself, I am just afraid that we would miss out coding for any segments
during our processing.

Re: Process HTML Tags Causing Problems

HI Jack

I don't know how you get to the url, but maybe it is a confusion  
between 4DVAR (in v12 4DTEXT) and 4DHTMLVAR
Or maybe you can have a look at theis:

If you look at the documentation of the command XML SET OPTIONS
(http://doc.4d.com/4D-Language-Reference-13/XML/XML-SET-OPTIONS.301-737765.en.html 
),
you'll read the following information : "XML With escaping (default  
value): conversion of 4D strings to XML element values with  
replacement of characters. The Text type data are automatically parsed  
so that forbidden characters (<&>¹) are replaced by XML entities  
(&amp;&lt;&gt; &apos;&quot;)."
So you have to use the command XML SET OPTIONS to change this default  
behaviour.

Re: Process HTML Tags Causing Problems

Thanks...that seems to be the result of running HTML Process Tags...

BUT...

There is no XML involved..at all...

The text is just straight text, with HTML coding.

I seem to be able to solve the problem by running

$HTML_Text_t:=Replace String($HTML_Text_t;"&and;";"&")

Before passing $HTML_Text_t as the body of the email to be sent out using
the SMTP commands.

I still would like to know why this is happening.

Re: Process HTML Tags Causing Problems

This is an encoding issue… As I recall, when calling PROCESS HTML TAGS, it also encodes the string (in this
case, it is encoding & to &amp [not &and as you noted in your replace string call).  You might want to look at
the PROCESS HTML TAGS routine to see if has ability to disable encoding.

David, when I struck this it turned out there was a bug in my Startup method code.
Try running in interpreted mode and Trace startup method code.

Re: Client Manager process (observation)

Is RDPClip running? It needs to be disabled, I believe.

Yes, that was my mistake in typing...in the code it is &amp...thanks for
catching this...I had to go back and check it out...
