Re: Novice - Problem with data encoding

[Antti Haapala]

 I have an XML doc that I generated using XML::LibXML that needs to be
 included as a hidden form field in a form post.

 The problem is that the browser is encoding the XML doc.

 ie.
 ?xml version=1.0 encoding=UTF-8?
 !DOCTYPE gtfd SYSTEM http://gftd/schemas/data.dtd;

 turns into:
 lt;?xml version=1.0 encoding=UTF-8?gt;
 lt;DOCTYPE gtfd SYSTEM quot;http://gftd/schemas/data.dtdquot;gt;

 which blows up in the parsing.  If I edit the result and swap back the 
 and  it works. How can I prevent the encoding of the XML data?

You have probably escaped the xml snippet twice yourself - check the code
of the page from your browser. If you see the value of your hidden field
as amp;lt;?xml..., you have done double escaping.

Just remove one of the escaping passes and it should work.

The browser isn't supposed to do any such encoding on its own. If it does
you need to change your browser. You aren't using Netscape 4.0, are you?

Thats what is wierd.  I don't do any escaping.  I think it might be embperl
doing the escaping because if I do a print of the XML doc string it has no
escaping.  If I put the string between [+ $content +] then it gets escaped.

Thanks for your help,
Chris

Yes, Embperl escapes your output per default, you can turn it off by using
$escmode e.g.

[+ do { local $escmode = 0 ; $content } +]

Gerald

P.S. The do { } is only necessary in Embperl 2.0

Novice - Problem with data encoding

[Chris Pizzo]

Hi,
I have an XML doc that I generated using XML::LibXML that needs to be
included as a hidden form field in a form post.

Code snippet:

sub getcXML   {
use XML::LibXML;
my $resp_doc = XML::LibXML::Document-new();
my $root = $resp_doc-createElement('blah');
...
my $content = $resp_doc-toString;
return $content
}

The html is:
form name=sndxml method = post action =
http://someserver.com/process_xml
input type = hidden name = xml_here value = [+ getcXML(); +]
input type = submit value = Order
/form



The problem is that the browser is encoding the XML doc.

ie.
?xml version=1.0 encoding=UTF-8?
!DOCTYPE gtfd SYSTEM http://gftd/schemas/data.dtd;

turns into:
lt;?xml version=1.0 encoding=UTF-8?gt;
lt;DOCTYPE gtfd SYSTEM quot;http://gftd/schemas/data.dtdquot;gt;

which blows up in the parsing.  If I edit the result and swap back the  
and  it works.
How can I prevent the encoding of the XML data?


Anyone point me in the right direction?

Thanks,
Chris
